API

Mattie_Kadlec

I think that was an API outage or something like that. I remember reading similar stories. In any case, you can look into GRVT as well. They don't require KYC.

PubbaBean

I think people in general trust data from CoinGecko more than CMC these days anyways. So I guess the obvious choice for better data would be CoinGecko API.

myurtsever

You could use FreeBnk Pay—it supports recurring crypto (and stablecoin) payments with full API integration. [freebnk.io](http://freebnk.io)

It's not just this sub. It's every sub ever since the API fees controversy. Where did everyone who left go?

For Crypto I use a script which lets me Trail SLs- Binance API mostly. Binance is my go to and also Mex is pretty neat too. According to my strategy I specify rules for SLs and as when there is a change the SLs change automatically in the system. Stocks are usually longer term beta for me. I use options to hedge then. And if it's a sideways movement- I use delta neutral strategies to get some theta. Options I do both for Crypto and Stocks: Let's talk crypto first- I always have my hedges in place so the maximum loss is always defined and along with another script Trailing my Hard SLs- Here my exits are both movement and time based. Crypto Options are not that mature. Especially because Delta tends to change a lot. Hence for Crypto Options it's mostly Hero Zero calls- Yes they work amazing if you know your winning rate and profitability quite well :)

italianwopper

Very likely I agree it's the API. I actually don't think it was a bot on gate; I think it has to do with the API I created. Although I set the permissions to not allow withdrawals. I suspect something has been compromised here imo. The only other thing it could be is that my logging details were somehow stolen off my device. But I have travelled through my browser history through every site over the past 2 months. I know every site I've visited, nothing else in my history. It's definitely not a phishing site. No friend or family has access or log in details. I've looked through signs on my device. I've run PowerShell searches, manually searched my event viewer. I've run a malware check nothing. No trojans either. I've run wireshark and am still monitoring my network, I don't see unusual IP's.

d0x77

There is no other possible way in the world to withdraw your money without any sort of verification other than API keys, that or gate just decided to pull them out (yeah unlikely). How does bots within gate work? Do you need to input your API keys anywhere or does it connect you through the bot using your credentials? Because my guess is gate encrypts the API keys before exposing them, thats the least security measure that they could do, but yeah API keys are the reason, im confident.

italianwopper

Yeah absolutely, I have never copied a bot or tried to use anyone else's. Hence why I decided to write my own script which I never fully completed anyway. Definitely sounds malicious to me. First time I've tried using API and I've been hacked. Sounds too coincidental. I was a fool for trying the API on my trading account. A user here said I should have had a second account, I agree with that. Hopefully someone else learns from my mistake.

italianwopper

I'm pressing on with the request for API logs. According to them, the back end verified the withdrawals as approved via 2fa, email code, funds password etc. Notifications sent as well. Although none received my end. No signs of access into my email, looking at the IP activity. No signs of any other mail missing, or read, or tampered with. Gate hasn't sent me proof of the notification emails, or the API logs. Hoping the police work with me in requesting that info.

italianwopper

The whole event occurred over about 1 and half hours. There were definitely manual trades made. I see your point here, as in an exploit by gaining front door access into the account, then manually selling the assets into usdt to withdraw. Otherwise an API exploit that runs it backdoor, would execute the events a lot quicker.

italianwopper

Yeah I def did not enable any withdrawals. The only permission it was given was to place a spot order. Altho, I think the API has something to do with it. It looks like the most obvious to me. Gate won't provide me the API logs, I have to request that through the authorities which I'll do. If it turns out to be an API compromise, then it's an issue on gate's side as the API was set by me to be restrictive. I suspect this is why they're being difficult and unsupportive with me. If it turns out to be a gate issue, it opens a rather large fucken can of worms.

d0x77

I have designed my own bot and im using api keys to place trades, so im in a very similar situation like yours, my only guess for this "stealthy" theft is that you had enabled withdrawals for api keys, and they got compromised by using the gate bot, there is nothing else i could think of considering you know all the scams and phishing links, and you do take precautions. There is no way someone can steal from a CEX, its very complicated, the only way to bypass all this is through API keys, check the permissions, im pretty sure withdrawals are enabled.

Top_Mind9514

“API’s” are a huge security threat/risk

italianwopper

100% I think it was an API exploit yeah... that's all I can pin it down to. It's become an argument as to which side was breached my device or my account directly. Obviously I'll be put on me, the funds are gone and albeit the risk was my choice. I think I'll stick to trading on a local exchange if there must be trading. Gate is quick to take money but when you're funds are lost you're the last person they'd want to help.

BendNo2750

Hey dude, solid idea on using AI to spice up those password guesses! If the pass is English-based (like words, phrases from hints), here’s a quick take on scripting it with an AI API: Loop a script that hits an AI API for deets on keys/setup) with your hints as prompts. Something like: “Generate 50 creative English variations of [hint1] + [hint2], mix in numbers/symbols from 2015 era.” Then feed the output list into btcrecover or hashcat for testing.

Admirral

this is really cool! Are you pulling all data for analysis from DexScreener API or are you doing something that is solana specific? Do you have a GTM plan ready or in the works?

mohicanin

Not only in this sub. Whol Reddit is being created with AI to engage ppl, make then interract so they can charge bigger money from LLM companies for API access.... I see shitloads of posts where "ppl" are asking literally dumb questions, on which they coulda have found answers in google in no time... Time to completly move on to X

amanj41

Been an SDE for 7 years. And I can guarantee you it costs *literally* nothing to store rows on a blockchain (for a developer) once the data is loaded. I don’t know the total cost to load this dataset into Algo, granted. But if you want to dump data somewhere and expose an API to read from it there is go cost to the developer themselves once the data is loaded on the blockchain. Compared to hosting a DB in AWS, plus a lambda or EC2 or whatever to handle the queries. And if someone decides to DDOS your service for fun either you pay for the DDOS protection or get hit with a bigger bill. In any case, this just boils down to semantics. Yes blockchain is more costly and inefficient. But I’m just pointing out that blockchains subsidize the cost of storage once it’s loaded and the users of the data instead end up paying one way or another

Azzuro-x

You may ask Gate.io for assistance more precisely if their internal logs show login with your credentials + successful 2FA verification + verification sent to your email address and/or any API based connection attempt during the incident. For the login based scenario I only see two options for the missing verification email (1) they did not send it meaning their side was compromised or (2) someone has access to your emails, confirmed the access then deleted it.

metamorphosis

No worries. Good luck. It's highly unlikely your 3 layers of security got compromised or some sophisticated attack to take ownership of your OS/ machine is also highly unlikely....so it must have been exchange/bots/API related.

Azzuro-x

99% of the trades on the exchanges these days are performed by bots. They are safe to use with the proper API settings - assuming the given exchange enforces the rules (which is fairly easy to check with a test withdraw request if needed).

metamorphosis

Not familiar with gate exchange and if these bots are gate official bots or user bots? To narrow it down, does gate offer API activity log? Re: script. Did you implement your own gate API or downloaded a library ? Where from ? Either way, yeah it seems too coincidental. Check addresses to which funds are withdrawn too. Check their bubble map and activity. That can give some insights https://bubblemaps.io/

Azzuro-x

Have you enabled withdraw as well for the API key in question or only trading ?

god_damn_you_tiger

macOS user? If so, perhaps you were the victim of zero day attack that Apple patched 5 days ago. But 16k sounds too small to exploit, attack should have been really sophisticated and targeted. I lean towards API compromise here tbh

amanj41

Cheaper for who? Doesn’t get much cheaper for users to have a free public database with negligible transaction fees. Spinning up a DB in AWS and building a service with an API is more expensive singe ALGO is so cheap. I don’t think ALGO’s low fees are sustainable in the long run tho

HSuke

Depend on the platform. I often deal with platforms where the public module or API documentation doesn't exist, and the only way to get it is behind a customer login or vendor support. I've worked on many issues where I had to report bugs for their products. Microsoft is notorious for having incomplete documentation, especially for function parameters/arguments. A single function for Exchange or SPO can have 50 different parameters, 40 of which have either no documentation or bad documentation.

cali_dave

Just make a best effort and be prepared to explain your rationale to an IRS auditor. Take the highest/lowest/closing cost of the day you made the trade and use that as your cost basis. If you're a day trader, you should know how to keep track of that stuff. Don't rely on an exchange to track things for you. If you have timestamps of your transactions, you can query Coinbase's API to pull price data on a 1 minute time frame (if you need to get that granular).

I’ve explained why the token price must rise so we’ll skip that. Enterprise chains failed because they were siloed. CCIP isn’t a “private chain” — it’s the neutral interoperability standard between public chains, private ledgers, custodians, and banks that allows money and messaging to be sent within the same workflow. That’s not something you can replace with just running your own server. There’s a reason why major banks like Jp Morgan and anz are completing proof of concepts. Yes, price feeds are many. Pyth, flare, band protocol we could go down the list. But the moat isn’t built around the cheapest option, when it comes to the level of institutions link are onboarding, the moat is based on reliability, reputation, and integration at scale. DTCC, SWIFT etc aren’t going to pull some free API feed off Yahoo Finance, they value resilience, uptime guarantees, decentralized validation, and legal/insurance frameworks. Competitors offer price feeds, link offers everything they need in one platform. That’s the moat. Again, I don’t care for current revenue. Eth was at 100b market cap earning peanuts for fees. I agree fees don’t justify LINK’s market cap today. But by your logic, Eths 100b valuation in 2018 was also unjustifiable. Your logic would have most likely faded the run to 500b. Both are SoV bets, ETH on computation, LINK on interoperability. Difference is ones narrative has already run and become mainstream, the others is just getting started. The fact you think it’s so easy to simply switch a legacy system that the entire financial world has been running on for the last 50 years is laughable. This is a technological shift that has been in the making for almost a decade now, swift and link have been working together since 2016. In finance, cheapest ≠ winner. Reliability and standards win. SWIFT isn’t cheap but banks still pay because it’s the universal standard. Once you’re the default, switching costs lock everyone in. LINK is positioning to be the SWIFT of interoperability, and I believe that’s why swift themselves are already testing and integrating it. That’s what I’m betting on. Only time will tell.

Wow API3 exploded for a second there.

Key-Boat-7519

Engagement’s tanked because the sub outgrew the mod team and the API changes killed third-party tools, but you can still spark solid convo by timing posts during U.S. market hours and cross-posting to r/BitcoinBeginners, r/BitcoinMining, and r/CryptocurrencyTech. Niche subs crave new voices and the mods there are less trigger-happy. Keep posts data-backed-link mempool stats or on-chain graphs-so automod flags less often. I lean on UsePulse to spot when BTC mentions spike and push alerts to my Substack so followers know when a debate’s brewing; Launch Club AI quietly handles the comment templating so I don’t waste time rewriting the same TL;DR for each thread. So yeah, smart timing, proof-first content, and rotating among smaller subs can still pull real engagement even with today’s stricter rules.

Rich_Instruction_428

Its not based on eth it runs on all EVM chains and AVAX and SOL and CANTON etc etc. The token is used to pay for chainlink services called API calls. You want something done on LINK network you pay LINK. You're also calling it a chain its not a blockchain is an Oracle network with decentralised nodes. LINK is 80% of all Oracle market on all chains and wins no matter what L1 wins LINK over ETH all day.

VirtualDream117

Did you submit API reading?

DaskMusic

BTC and ETH are natively integrated into the ic network along with others like Solana, which gives BTC fully onchain smart contract abilities without the need for bridges, wrapping of tokens and 3rd party oracles since it enables any integrated asset native web2 API calls. Chainlink does have some competition and it is not the only one. Crypto would not collapse without chainlink or icp for that matter. BTC will likely always survive.

Ur_mothers_keeper

They won't wash out. They'll continue to diverge in interesting ways. Every single parameter you're using from the API to make decisions squares the number of possible outcomes. You're creating a chaotic system and trying it in different environments. Thanks for this BTW, it helped me understand something interesting I hadn't really thought of before.

EarningsPal

The API power. Infrastructure for any application to be a bank app.

dca-bot

The whole idea started over 6 years ago. I wanted to use DCA and build a quick and dirty script to execute it daily via API on my favourite exchange. I guess it was like 10$ per day. I talked with some friends about it. Some wanted to use the same script since back then no exchange was offering DCA. So I added a database to manage multiple "clients". One friend then said: "Yo why not scale the order size depending on market conditions, you could maximize your stack". That was the moment I digged deeper and created the multiplier engine. Over the years I tweaked it, using feedback and data driven development. Early this year we added a self service interface and invited more friends to use it. So in total I pay like 50$ for the hosting per month but invested many hundred working hours. Serving around 25 clients.

AskMeIfImAnOrange

Devve. You won't have heard of it (yet), but it is a permissioned chain specifically designed for Enterprise. It ticks the boxes that prevents most chains from being fully utilised by big money because of privacy, security, regulatory issues, etc. The chain is live and has been developed in stealth the last 9 years. They have not marketed it yet, they will begin when their partnerships start being announced - beginning Q4 this year. Basically, companies can spin up shards customised to their specific needs. Each shard operates essentially as a standalone blockchain, but multiple can be easily connected to work together e.g. you operate in multiple territories that have different regulatory requirements, or you want to scale up TPS as necessary. With this this system TPS is essentially infinitely scalable. Connection to the shard is via API, so incredibly easy for Enterprise to integrate. All of this will be offered as part of a Blockchain-as-a-service system. Similar to AWS but for blockchain. Anti-fraud, theft and loss protections are built in at the consensus level (and are patented) - things which are essential for Tradfi. Swaps also occur at consensus so no risky smart contracts are needed for trading. And they can occur while the user maintains full custody. Essentially combining the best features of current CEX'es and DEX'es For their first, big, on-chain project, they have partnered with one of the largest Tradfi enterprises in the world to create an exchange combining crypto and RWA capabilities. Instant swaps with self-custody. The partner will be revealed Q4 along with the launch of the exchange. Expect Bloomberg, CNBC, Fox, etc coverage. That is how big the partner is and how important this project will be to Tradfi. This is not a monolithic, permissionless blockchain. It won't satisfy the desires of the anti-government crypto users. What it will do is allow the really big Enterprise money to start using blockchain in ways that are practical to their requirements, not the other way round.

UnsersGottaGo

Each system only words as well as their weakest link. When someone chooses trust an exchange, they take on all the risks of their OPSEC, without being able to verify it: - Exchange hack or rug pull - Malicious or negligent employee - Compromised web server, API, or login gateway - Missed security patches on their systems - Your devices always connected to the internet for logins - Seizure by exchange management or government order - Restrictions on where and how much you can send - KYC data collection and permanent records of ownership, amounts, and transaction history - Uncertain privacy future — you don’t know if they’ll sell your data later or leak it Every one of these has been talked about or experienced first-hand in this subreddit. the exchange-truster is betting they’ll stay solvent, secure, and honest — and they won’t know they’re wrong until it’s too late. By contrast, self-custody means you bet on yourself - your own discipline, planning and secrecy. - You must protect your seed phase from loss, theft, or damage. - you must maintain plausible deniability - having no evidence of bitcoin at all, maintaining fiat idenity, use of duress wallets and passphrases (see: Coldcard) - You must do your own inheritance planning, or the keys die with you. - Avoid physical coercion - don't feed or go near situations where someone can force you to hand over your keys. - maintain secure backups without revealing locations - practicing flying low so you blend in like all the other worker drones until one day you decide to Opt Out. The best choice between exchange custody and self custody is which risk you're more confident in managing - theirs, or yours.

I think the moment you posted or commented anything in a 18+ sub your profile gets marked as such. And remember when many normal subs switched to 18+ as a protest against the third party API ban? I think since then most profiles are 18+ now.

my bad, it is not actually multisig but Tron's account permissions feature. most of the wallets out there don't display such information, so all you get when withdrawing funds is a raw API response saying you don't have the permissions to withdraw. I don't know if they can make this scheme for ERC-20.

because if history is any indication, the companies that physically implement these ZK proofs do so very lazily by first storing the unencrypted data in a database before sending it to the ZK proof API. then some douche with a laptop of said database backup file lets it get out by writing their password on a post it note and going on a 4 hour lunch.

*TLDR [NanoGPT](https://nano-gpt.com/) offers private access to every AI model you can think of. No subscription, pay only for what you use, text, image, video. No account needed. Reply for an invite, or deposit as little as $0.10 to try it out..* # Why is this relevant for me? If you want to use the top AI models (like o3-pro, Grok and Veo 3) but don't want a $200 subscription, we're the place to go. If you want to use the top AI models but don't like the idea of linking your name, personal details and credit card to the prompts you do, we're the place to go. If you want to use uncensored models, we're the place to go. If you care about crypto being actually used, we're probably a place you want to check out and give a try. ## Improvements - **Account deletion is now a lot easier**. This used to be manual which frankly, not great. You can now easily do it from Settings and optionally provide a reason for deletion, but there's no need to do so. - **Open source model mode**: toggle open source mode in [Settings](https://nano-gpt.com/settings) and all closed source text models will be hidden from the options. For all of the open source models that we offer we do NOT run them directly through the provider, because many of the best open source models are Chinese and frankly we understand that distrust. We use no-log providers and are largely moving to TEE. - **TEE models**: we have a [blog up on this here](https://nano-gpt.com/blog/trusted-execution-environments-and-confidential-ai-on-nanogpt). They are the most private way to use open-source models online. We have a TEE category where the models are verifiably run through Trusted Execution Environments. For the newly added Qwen, Kimi, and GLM (see below) we also run them through a provider that claims TEE, but we have not been able to fully verify that yet so they're not shown in the TEE category yet. Deepseek V3 for example can be run through TEE. - **Price decreases**: for video and image models we should now be pretty much the cheapest or close to the cheapest provider for all of them. If you're running text models via API we match the price of the direct providers or beat it, so let's say ChatGPT costs $5 per mln tokens directly through OpenAI, we now charge $5 per mln tokens via API ourselves as well. For many of the open-source models we're cheaper than any publicly available option. For anyone that wants to build AI into their application/website - deposit anonymously, don't create an account, yet get the same or lower prices than at providers that want your credit card. ## New models **Text models:** - Grok 4. - Vercel v0 models. Very useful for frontend development, especially next.js/Vercel applications. We're the only ones that offer this as far as we know. - [Study mode](https://x.com/NanoGPTcom/status/1951290272064627038)! ChatGPT with a custom instruction designed to help you learn through guided discovery rather than providing direct answers. - Qwen 3 Coder, Qwen 3 235b a22b instruct + thinking. - Kimi K2 (also via Groq for super-speedy inference). - GLM 4.5. - Step 3 **Video models**: - Veo 3 image to video - Veo 3 fast (cheaper), text to video and image to video - Wan 2.2 (full, 5b and Turbo). Cheapest version here costs just $0.05 per video and has surprisingly good quality. - PixVerse 4.5 - Vidu Q1 - Face swap video - Longstories The prices on our video models have also been much decreased. Using them directly via the website or via API we should now be the lowest or one of the lowest priced providers for all of them. We now also do automatic refunds for failed generations. **Image models** I'd love to list them all, but it's genuinely too many. We added about 30, the biggest ones are Flux Krea, Hidream Edit E1.1, and Higgsfield Soul. Also face swap, which is quite fun to do. Prices for our image models have also all been dropped. That's all - happy to answer questions, and would mostly be happy if this inspires some other merchants to also start accepting crypto.

Of course the web2 API is still an issue, but you can get around that by talking to multiple data providers and establishing consensus. If you're interested, have a look here: [https://internetcomputer.org/https-outcalls](https://internetcomputer.org/https-outcalls) It first shows how ICP can do web2 requests from the chain itself, and also how you can us multiple web2 sources to get reliable data on-chain (in this case exchange rates). Of course there's some limits (e.g. 10 exchanges could collaborate to fake data), but every system requires some trust assumptions

Decent_Taro_2358

It is. But you can pay a mule to buy Apple Developer, pay the 99$ and release an app with some malicious code. I doubt Apple will find a hidden API call that sends your private key to a server. Your app gets removed, the mule gets the blame and you walk away with 8 Bitcoins.

In Studio, you will be able to customize your model through fine-tuning, adding vector DBs, or smart system prompts (or combination of all 3!).  After that, you can: 1. Use it privately 2. Plug it into an external app through our API 3. Or list it on Vertical Stream. If listed, others can use your model, and you earn 85% of the revenue it generates. This enables free market dynamics on our platform, rewarding those who build quality models.

I’m not familiar with how ICP works but the oracle problem can’t be solved. It’s like if someone says they’ve invented something that violates the 2nd law of thermodynamics. It just can’t happen. If the information is not natively on the chain, it must be added, if it must be added, then there is someone or something that adds it. That thing that is adding the information onto the network must be trusted. For example, who manages the API in your example? Who updates the thing that updates the api? If it’s a sensor checking the weather in Istanbul for your corn futures contract, can someone manipulate the sensor? These are all subject to manipulation, which means you can’t have a trustless or anonymous system. You need actors with reputations that can guarantee information is correct who are liable for failures, so you can sue them if the thing messes up. At that point we are back to square one, companies and institutions are being trusted to manage the data anyways, they can run the smart contracts themselves without needing a blockchain. The only thing you can do with a completely anonymous system is swap unbacked cryptocurrencies and tokens with each other, which is a tiny sliver of what defi was promising. The moment you introduce tokenized assets or external data, you can’t do the whole trustless/anonymous thing, and therefore there is no point to using a blockchain. The exception to this is the 3D printer analogy, for small actors trying to create something on their own with what they can easily get at hand, it makes sense because you can set these things up on the cheap, but the operating costs are substantially higher, at scale it will never be able to compete. Basically good for prototyping financial products.

There are solutions to the oracle problem if you look. For example, the icp network does not need oracles to talk to web2 API, it also uses a reverse gas model so no user gas fees, and has native bitcoin integration, so no need for bridges. It's essentially a protocol for a distributed compute platform that glues a number of blockchains together like ETH, BTC, SOl using chain key fusion with everything fully onchain. Factor in utopia for private enterprise features explains why Hbar partnered with dfinity. Is dfinity still hated though in this sub ?

Algo-trader on crypto, so yeah, using API and trading on Binance. Python for: market analysis, backtesting, documenting, portfolio analysis, risk management, and of course - trading. Deployed on Railway and Northflank + some services run on GitHub Actions. Front and analytics - Node/Express and React - Next.js Don’t know about better trading conditions, but for algo-trading there hardly any other ways to do it reasonably for retail and even businesses. On Binance my trading volumes are big enough not to be a “Regular” account holder, so there’s indeed some reduction in Maker and Taker fees, but anyone can get to those volumes that give you some dicsounts. As for those asking how hard to make a bot - it’s actually very easy, especially nowadays with AI, hard part is making sure that bastard can make money and not lose too much too fast.

CuriousGeorge22_02

Don't you need some sort of external interface to access the API and use it?

Odd_Pen_1041

I see so the bot can sometimes literally make a wrong trade or sum? When i start trading with the bot i get the API key?

Odd_Pen_1041

Never done anything related to API trading, how hard is it to make a bot?

reZZZ22

The Coinbase Email I received had this in its email. Wallet type: Trezor Metallic Status: Setup in progress Estimated completion: Within 24 hours Once the integration is complete, you will be able to manage your digital assets directly from your cold wallet interface using the Ledger API.

wynmead

I realize that. But you if you are processing thousands of combinations how does that work quickly? Is there an API one would use?

Humphrey-B-Bear

So it's a competitor to Stripe with less API fiddling. Perhaps the Trojan horse here is that PAYPAL just entered the stablecoin business.

Odd_Lengthiness_2175

As a general rule, you have to track your cost basis yourself. There's a number of services that do it now if you plug in all your API keys and wallets. Coinbase will issue a 1099-B, but your cost basis will only be accurate if your funds never left the exchange or you manually enter it for funds transferred in. If you buy an ETF like IBIT on Fidelity (or whatever your favorite broker is), it will be tracked like any other stock.

Cosmo_EVA

Hey Gobrrr. Thanks for the thoughtful questions. **1. How are you different from other VPN/antivirus projects that ended up failing or rugging?** Great point to raise. Just to clarify, the VPN is an optional add-on to Sentinel, not our core product. We’re not a “VPN project”, we’re a **security protocol** at our core and our flagship offering is the **EVA API,** integrated across 50+ partners. Just today, we announced a new integration with **Quantum Foundation**. To be honest, I don’t think there’s another startup you can fairly compare us to. Especially not at this mc, with this level of adoption, recurring revenue, and an ecosystem this robust. **2. How can I be sure your tools are safe and not doing anything shady in the background?** Totally valid concern, especially in crypto. None of our products require wallet connections, seed phrases, or access to your private keys. We designed them with user safety as the priority. We’re a security protocol...if our tools weren’t secure, we wouldn’t exist. And so far, that trust has helped us scale quickly and form strong partnerships. **3. Does Sentinel store or share any of my data?** No. You log in via your Chrome account, and that’s it. We don’t ask for, collect, or store any personal data**.** **4. What’s the benefit of holding $EVA?** $EVA is deflationary by design. Every single trade made through Instinct (our newly launched sniper bot) automatically buys back and burns $EVA. We're two days post-launch and over **$50K worth of $EVA has already been burned**, directly from revenue. As you know, burns increase scarcity with every transaction and, as volume grows, so does the demand, kicking off a flywheel that makes holding $EVA more valuable over time.

Extiint_EVA

Thank you for your question! 1. EVA is adopted in the space. We could perhaps discuss metrics, but it's worth noting that the underlying technology powering our extension is the same one we offer to other projects integrating our product via API. We are not focused exclusively on security, our product suite spans a broad range of web3 experiences. This includes trading (which is currently gaining significant traction), external API hooks, the extension you mentioned, a specialized security token detection tool, and a strong revenue stream as a company 2. Different services implement different levels of security. If you're referring specifically to our browser extension available on the Google Marketplace, it's a zero-risk product. We've designed it so that we don't collect, store, or use any user data. Sentinel runs entirely locally in the browser. Google also has a rigorous review process, every single update must be reviewed and approved. Being a security-oriented product, we must provide extensive proof that no external code is executed. Along with KYB proofs of course. 3.The only case where we store any data is related solely to the VPN (you need to turn it on yourself). In this case, we retain visited links and IP addresses for up to 30 days, standard industry practice, and actually a security measure. Not storing this kind of data would invite bad actors. Other than that, we store absolutely nothing. In fact, we don’t even use password credentials, all authentication is handled via Google Login. All of this is also in our privacy policy 4.EVA has several utility use cases: * A portion of our revenue (from partners who pay monthly for API-based security services) is used to buy back EVA tokens, effectively redistributing value to token holders. * We also recently launched a trading bot that has been performing exceptionally well. 100% of the bot’s revenue is used to buy back and burn EVA, making the token deflationary. You can check our chart — you’ll see hundreds of small EVA buys over the last few days. Each buy corresponds to a transaction executed by a user, triggering a buy-and-burn event for EVA.

You can run a asic with only one hashboard for 1kw. They can also ramp down via firmware. But I think the min on my Antminer S19 is 2kw. Full power is 3.2kw. I use Home assistant to turn it on and off when solar is available and then when the house overheats and it sucks hot air back in it overheats, this is when the firmware kicks in a d reduce the power. I use Luxor firmware and I think you can API into it with ramping signals.

Using Loveable to make a rapid prototype with a couple of features: 1) sentiment analysis tool - APIs are connected to Open AI, News API, and reddit. The tool looks at the last 90 days and uses hugging face sentiment analysis transformers to give a score from -100% (bearish) to 100% (bullish). Im only a couple weeks in so treading lightly adding a ton more sources and APIs so it doesnt break. Right now its analyzing 256 news articles and 50 social media posts. Id love for this to grow but i break this stupid thing once a day trying to expand and tune search results 2) predicting system: uses advanced AI ensemble techniques (this is not just bullshit TA, although TA is part of the calculations) and 2 years of rolling data (id love to make this bigger and use all time, but again it makes the script work much harder and breaks) to predict 24h, 7dd, 30d, 60d, and 365 days. The script takes that two years of data, compares it against the sentiment analysis, 4 ensemble models (random fortest, extra trees, xgboost, light gbm) to compare simulations and validate its own outcomes, and technical analysis Sorry that was pretty long but its a science based tool, not just total bullshit which is what im trying to convey 🤣

Cosmo_EVA

Hey Michael! Appreciate the warm welcome and great questions. **1. Is EVA open source?** No. Our AI is proprietary. We’ve already been copied once (a team frontran our original product), so it’s important we keep our code secure. Our edge comes from the accuracy and performance of our models and, frankly, that’s why we’re seeing strong adoption. We can’t give that away. **2. What’s the business model?** It’s multifaceted: **- API Revenue:** We generate monthly recurring revenue from protocols and individual users integrating our API. It’s already outperforming tools like GoPlus, QuickIntel, and others from a tech perspective, and with v2 on the way, we’re expanding both our accuracy and total addressable market. \- **Instinct Trading Bot:** We also earn from Instinct, our trading bot. Every trade on Instinct burns $EVA, so usage directly benefits token holders. We did **$200K in volume within 24 hours** of launch and we’re confident we can 5x that, which will supercharge the burn mechanism and token utility. So to sum it up: We’re not just building a 'product' (I dislike referring to web3 companies like this, we're start ups), we’re building a sustainable ecosystem, with real usage and real revenue behind it.

Cosmo_EVA

Our API is used by a mix of protocols and individual entities. Some integrate it directly into their products, others use it for personal trading and analysis.

Cosmo_EVA

Hey Meeleen. Thanks for your question. Calling it an 'antivirus' is just a familiar shorthand, but Sentinel is purpose-built for on-chain threats - something traditional antivirus software doesn't offer. Think of it as your silent bodyguard while you browse Web3: \- **Smart scanning:** It detects Web3 scripts on a site *before* it loads (contract addresses, wallet connect prompts, etc.) \- **Reputation scoring:** We use top-tier cybersecurity engines to score the site out of 100. If it ranks low, Sentinel blocks it automatically unless you override (trust/report). \- **Drainer protection:** Malicious links and drainer scripts are stopped before they can even load. That means no accidental wallet connects, no surprise signatures...no drain risk pretty much. \- **EVA AI-powered:** It runs on the same AI engine that powers our audits, sniper protection, and partner API. All of it is trained *specifically* for Web3. So the key differentiator is that traditional antivirus scans files. Sentinel scans *interactions*. It protects you at the moment of risk, when you’re about to sign, click, or connect. I don't browse without it. For us web3 natives, it's invaluable.

So in the case of the strike app, it doesn't have a public API so you have to do an couple manual steps. At the end of the year you'll need to import a transaction file. Also strike updated their account statement, so for Koinly, you'll need to read this and see if its worth it: https://feedback.koinly.io/apicsv-issues-public/p/strike-csv-account-statement-is-not-recognized-unknown-file?_gl=1*x7qqb4*_gcl_au*MTE2MTU1OTg4Mi4xNzUxNDI5MDA5LjEyMDE1MzE5NjkuMTc1MTQyOTAxMC4xNzUxNDI5MDEw*_ga*MzE4MzU0MzY0LjE3NTE0MjkwMDk.*_ga_2YY60QTWGC*czE3NTMzMzU3NDAkbzMkZzEkdDE3NTMzMzU3NDckajUzJGwwJGgxMjgzMzgwNTAz Transfers. Lets say you buy on strike and then transfer to a ledger or another exchange. You'll connect your wallet to koinly or cointracker. It normally will have all the transfers connected but since Stike has som incompatabilities you'll but need to make some changes. Example, it might show in you imported transactions that you made a transfer from strike. You'll have to update the record to show it went to your other wallet, since their is no API to make it easier for you. For the most part, it makes the tax docs easy, but you may have some issues that can assist you with , but it should be way easier than doing it yourself because: Staking ewards count as income Buying and selling portions is hard to track properly Are you doing HIFO, FIFO, LIFO? Are you global tracking or wallet based tracking? Etc. If you are gonna buy and just transfer to cold storage, then I suggest changing to buying from an exchange that integrates better with a crypto tax. tracker. If you hodl on strike and prefer it, you'll need to decide if its worth it to use a tracker but have to make occasional updates to your records.

I do on kraken advance through their API with a custom script I wrote, and I imagine you could do it with coinbase’s api too but I can’t speak from experience on that one

SuperbLeg3056

For those asking, the forensic audit will focus on price feed vs spot divergence and synthetic liquidity behavior. If anyone has raw API data from Bybit during liquidation spikes, feel free to DM or share here.

Nitram_2000

Have a look at Level Up Your Brain on YouTube. He shows a way there of how to use the Coinbase API to do recurring buys with Coinbase Advanced which has lower fees at no extra cost to use. I set it up at the start of this year and it’s been a godsend. Daily buys, up or down, just DCA.

This is a high-effort scam. The team is doing the bare minimum to pretend its a legit project while secretly profiting off it. Team is super sketchy. They barely communicate with the community, and all their updates are dead and unrelated to community concerns. Other than one of the co-founders, they never revealed themselves after 2022. Much of the original team is no longer around. One of the co-founders sued the team years ago and disappeared. People couldn't withdraw for years. And once they could withdraw, it was only in tiny amounts. The app kept lying about KYC and most people never got KYC to work, so they gave up. 93% of the supply is locked up. Most of that is because people can't withdraw their supply. Network is completely centralized and has no consensus protocol. It's just a centralized database with the a public API that took years to launch. We have no idea how much the team is selling.

To add more info to the original comment I left here that you responded to (at first I thought this was too much information, but now I think it fits), I used gemini 2.5 to help me write a python script that could retrieve this information, but in the end, it failed because the etherscan API (as far as I am aware) cannot read information on binance smart chain.

sgtslaughterTV

Maybe I was not specific enough. I'm looking for more info on a BSC token. BSCScan's API key is deprecated and now you have to use some new multi-chain API that's on Ethereum and it is not presently fully up-to-snuff.

Wendals87

I use koinly. Add your exchanges by API or CSV or your wallet It may take some tweaking but unless you have gone full defi with liquidity pools and unknown tokens and stuff it should be pretty accurate

If you want free options, you might consider scraping Twitter data yourself using the Twitter API (though it has limits) and then running sentiment analysis with tools like VADER or TextBlob

Lazy take. Sure lots of chains claim scalability but Keeta actually hit 11m TPS in a live audit. They also will have the first On-chain credit bureau offering non-collateralized loans and protocol level KYC/KYB/AML with footprint and SOLO API.

Didn't those Covid apps require an official API to be released by Apple/Google specifically to enable the contact trace use case? I understand that something like this would be possible to implement on an OS level. I just suspect that this wouldn't fly if an app tried to do it.

Proj3ctPurp1e

Looking at both transactions on Solscan, it looks like they both failed because Exodus was trying to create a token account using an API that USDT does not support. It also looks like both those transactions failed. I'd reach out to Exodus support. They'd be more likely to be able to answer why your wallet tried to do that if it was just a basic transaction.

Secret_Operative

Block clock will display any text you send it. Write a small script to scrape the count and write it to the clock API.

Yes linking such screen to API for live stream events is great, they only potential issue is refresh rate. Getting stable and clean look on videos / streaming is hard.

You can use MQTT to send messages between the Meshtastic network and tcp/ip. I made a NodeRed flow that proxies payload over Meshtastic (required both ends). It's super slow even on the fastest speed, but it works. I should note that I basically had to write my own Reddit API wrapper for this, as http was just not happening. It could probably do simple webpages, sometimes that you could do with Lynx.

What are some of your most unlikely, "Oh, you're in crypto? I'm in crypto too." stories? I'll post mine first... I was smoking a cigarette in an airport in Milan. A guy, dressed rather professionally, also entered the smoking room and entered an online conference. I couldn't help but overhear him saying, "KrakenPro API" or something like that. Then I fire up my Kraken app while he's in the meeting, glance at him, and then say, "Pssst." He just kind of glanced back and nodded. Then I took the stylus out of my phone and wrote this message: "I work in BTC mining. Got a business card?" I walked up to him, showed him the message I wrote on my phone, and then quickly switched to a photo at work installing bitmain devices. He gave a big smile and said, "LinkedIn." So we swapped linkedin. When his online meeting ended we chit chatted a bit and went our separate ways.

Buying alts. I entered at BTC @ $7800. Put a good chunk into alts, day traded alts for a while and had overall slow but steady gains, but when that major drop happened, all the alts tanked and never recovered. Essentially, my gains were neutralized by my losses. I'm thinking I should train an AI prediction model (I've already done this before) and set up automatic trades via an API with the lowly alts that I still have. Why not experiment with it at this point.

They actually have 3 clear tiers/hierarchy; * Tier 1: Primary Source Data (The Gold Standard). This is verifiable, timestamped data generated by a third party at the time of the transaction. Eg CSV/API Transaction Reports from broker, Blockchain Explorer Data, Purchase/Sale Contracts. * Tier 2: Corroborating Third-Party Data (The Backup Plan) This is what auditors rely on when primary records are missing (e.g., from a defunct exchange). Bank Statements, showing a USD transfer to a specific crypto exchange on a specific date. Credit Card Statements, also showing payments to exchanges. * Tier 3: Taxpayer-Created Records (The Claim, Not the Proof) This directly addresses your point. This is the weakest evidence and is generally considered insufficient on its own. Spreadsheets/screenshots, The IRS views a spreadsheet as your calculation or log, not as proof. An auditor will treat it as simply your current claim and then ask for the Tier 1 or Tier 2 evidence to substantiate the numbers in it. This means in a strong sense you have tier 1, primary source data that will forever remain immutable contradicting your cost own basis calculation, so for every future disposal and calculation (on that asset) there is Tier 1 data exisitng that may/maynot refute. * The auditor will then say, "Thank you for this record. It shows when you took self-custody. Now, please show me the records for when you originally acquired the Bitcoin that was sent from that exchange wallet. I will also need the bank statements showing the fiat transfer that paid for it." I think you might be confused about capital gains tax in the first place. Remember it makes absolutely no difference whether you touch fiat currency or not. Swapping crypto for a car, a house, a coffee, or even another crypto is a taxable event. The idea of living in a "closed-loop" crypto economy to avoid taxes is a myth, due to the misunderstand of how capital gains tax work, and waiting for this to change will never solve your large underlying tax problem. You can't simply avoid capital gains on an investment house just because you used the gains to buy something else and not cash, otherwise everyone could avoid capital gains, forever.
