Since you're more technical user I'd suggest Nunchuk. [https://nunchuk.io/](https://nunchuk.io/) It has the best multi signature support that I've seen. Works with various NFC enabled devices. Allows setting of fees by transaction. easy to see all the wallets you've created. Open source on github: [https://github.com/nunchuk-io/resources](https://github.com/nunchuk-io/resources)

It depends on the hardware wallets because there are several different designs. But yes you can be air-gapped at all times. Options are: 1) Plug in to USB (trezor, ledger). Not technically air-gapped, but the seed never leaves the device and the cryptography is done on the device. 2) Using microSD cards to transfer data between host and signing device (COLDCARD). 3) Using QR codes the transfer data between host and signing device (SeedSigner, Passport, Jade) 4) NFC. I think Jack Dorsey's company is working on this

I think the NFC signing is convenient. But not sure of the value of multi sig (w/Tapsigner) if you’re not collaborating.

No one should ever be keeping their funds on an exchange, period. That said, of all the exchanges out there, there are a handful that I continue to trust will remain around for as long as people are willing to even be investing in/purchasing/using crypto. These are the exchanges that I personally use and would recommend to others without hesitancy. Note, this is a US-centric list. Those include: * **Coinbase** (love them or hate them, Coinbase is one of the oldest continuously operating exchanges around and definitely right up there as the most well-known \[aside from Binance\], they have been one of the companies at the forefront pushing through new technologies for the industry and it's what I recommend for newbies. It's easy to use and they are rock-solid for 99.9% of people - the ones who I typically see making complaints tend to either be about something temporary that has been resolved or it's people who are doing something sketchy that has gotten their account flagged, of course there are extreme outliers but they are a fantastic exchange for most people, aside from their somewhat high fees). * **Gemini** (similar to Coinbase in terms of their legitimacy/institutional adoption as far as custodial holdings/investments are concerned, strict KYC standards similar to Coinbase, based in New York state which has the most insane requirements for any kind of financial business in the country especially for crypto-related stuff, also they just recently announced their new credit card offering which implies even further regulatory compliance) * **Binance** (while there's a big difference between Binance and Binance US, both are fine. The US one has been especially transparent and gone under a concerted push to be super compliant with all kinds of regulatory crap, going as far as to hire their CEO because he was formerly working for the SEC on crypto-related stuff. The US version has also massively expanded the number of tokens they have available and their support has improved dramatically when I have had to use it recently.) * **Kraken** (rounding out the list here with Kraken, who is certainly not at the end of the list because they are the worst, it's not an ordered list. Kraken is actually incredibly underrated in my personal opinion, their interface seems to be what drives some people to dislike them, though personally I think that once you figure out how you want to customize it, it's pretty great. Their support has been second-to-none for me, I was able to get a hold of someone and get support within 30 seconds from a real human being at some insane hour of the morning on a weekday, and had my issue resolved immediately. Can't say I've ever had that happen before. Also, they have by far the most customizable options for you as a user than any other exchange and it's very clear that they have an immense dedication towards security...they are the only exchange, for example, that allows you to submit a public PGP key that they will use to encrypt any outgoing communications to you with, for additional security and verification purposes. That's just one of many options. They have the 3rd most options of different assets available, out of the 4 exchanges listed here \[Gemini has the least\], but they do have good liquidity on all of their pairs and their fees are not bad.) Hopefully this list is helpful to some of you. **Remember,** it's repeated *ad nauseum* for a reason **"not your keys, not in your own wallet, NOT YOUR CRYPTO" - learn to live by this rule! Get yourself a self-custodied setup and hardware wallet ASAP!** Ledger Nano is a good one to start off with. Even better still, ***get a hardware security key*** (Yubikey FTW) to use ***in addition to using a password manager*** (keepass and bitwarden are the two best ones), which has second factor authentication/TOTP generation built in. ***Stop using your phone for everything, people lose their phones.*** ***!! Especially stop using your phone for any kind of SMS-based 2FA codes. !!*** You can use a Yubikey via NFC or plugged in via the port on your phone to securely generate your 2FA for signing in if you are insistent upon using your phone, and it works on your PC too. Also look into something for keeping your private key/mnemonic recovery phrase stored safely, such as the seedplate (by these guys - [https://coinkite.com/](https://coinkite.com/) ) or similar products out there, and keep that shit secured! I would also finally recommend taking the time to do a personal security audit of your entire setup as it currently stands. There are people out there (such as myself) whose job is providing such audit services to save people from losing their funds, falling victim to ransomware and various other attack vectors so as to mitigate risk as much as possible. Any good provider of this kind of service will be frank and honest with you and give you a detailed breakdown of where you need to make changes to your OPSec and won't be trying to sell you on some unnecessary and expensive services or subscription bullshit. Frankly, you can do this kind of thing on your own, the people who hire me are mostly too lazy or lack the knowledge to do it themselves, as few realize just how many ways they are exposing themselves to serious losses (simply by being only slightly careless, or worse, by not taking advantage of the abundance of free/cheap tools and services available to keep you safe.)

Don't know of anything I'd call comprehensive, but I found this to be one of the most helpful guides I found: https://www.suresats.com/post/best-bitcoin-hardware-wallets I have a Coldcard and am happy with it, although I would say it is more geared for a power user. There is no companion software wallet, you have to connect the Coldcard to one yourself, like Electrum or Sparrow (desktop) or Bluewallet (mobile). I think the Passport by Foundation Devices looks really good too but I don't have hands-on experience. I like those two because they heavily prioritize security, are bitcoin-only, and are air-gapped (no wired connection to a computer required, all transaction and signature info are passed by SD card, QR code, or NFC). But they are on the pricier side.

The Coldcard has 3 ways to get a transaction signed. It can act as a virtual disk and operate much like a ledger, being connected directly via USB. Mk4 has NFC and can work that way. But most ColdCard users use the built-in micro sd slot to sneaker net the PSBT files between device and coldcard.

I assume that my LN wallet must be online. The card just signs the money request and then the cash register informs my online wallet that it should send a transaction. Am I right? I am just guessing.

Yeah, this is a very important point to make. Humans each have a tolerance for security versus convenience. And the fact that most of us choose the same password for everything tells you most of what you need to know about that. I suppose it's important to note that he is scanning a static code. If he was scanning a dynamic code generated by the servers phone he would cut out about 70% of that time out, e.g: typing in the peso amount, generating the invoice himself. It is a pipe dream at this point but if 10 years in the future we are using NFC technology to transfer sats, we may look at videos like this as vital stepping stones towards a faster, more secure technology. Much in the same way that using chip and pin technology was a faster, more secure technology at the time, but much slower than current tech.

You can validate transactions via satellite. You can make payments through anything, Bluetooth and NFC are options, even with a piece of paper and pencil if you know the math.

Exactly! This is very similar to when the car was first invented. People’s frame of reference was that a car was a horseless carriage. Eventually people will just forget about these debit cards altogether. However, I will say that it would be ideal for merchants to accept lightning payments through NFC as well since tapping and paying is more convenient than the QR code. Banks normally use terminals which accept swipe, insert, or tap. With lightning, it would be tap and QR code.

Ya agreed. It’s got to be easy to use. China is really good about using mobile devices with bar codes.

But people also need a reason to use it. If I can just pay with my NFC phone, bank card and it’s authorized in seconds at a store why would the average person want to use it? It has to be able to do everything fiat can but better and better enough that it’s dumb to not use it.

2 questions: \- 'NFC reader'(NFC chip) embedded in shoe - why it can't be cracked and dublicated so several fakes links to same on-chain record? \- Why somebody should use smart contact instead of just regular payment in cash/via paypal. Yes, this mean that smart contract records of owner and 'real' owner will differ. So what? Nike have agreement with police forces and courts all over world to make it possible to return shoes to owner according to smart contract? This remind me marker code system our country tries to implement for alcohol and many other things. Every item is coded, all transacations between manufacturer and end user scanned and sent to centralized system. end user can check code and see path. retail is NOT allowed to sell if code is not readable or they don't have this item according to central system. Official reason for this to exist - prevent fakes. (Likely) real reason - taxes. System uses special kind of DataMatrix code.

> Surely the private key isn’t stored in the shoe itself Even if it were, it's not exactly difficult to duplicate an NFC chip. This is the whole issue with "smart contracts" and off-chain data or physical goods, they can only ever be authoritative over data that is on the chain.

> The no-coiners can hold their whining since owning the NFT entitles you to a physical pair I guarantee you if I steal your NFT Nike isn't going to give me a free pair of sneakers. > The back heel of the physical shoe has an NFC reader that is linked to the on-chain asset which verifies the product's authenticity. This, beyond a shadow of a doubt, ends counterfeiting The chain cannot be authoritative over anything off-chain, and that goes triple for physical goods. Just put in an NFC chip with the same identifier, boom, counterfeited. There plenty of other workarounds as well. > This means, the consumer would be saving money As the poster listed above, the savings would come from Nike selling direct to customer in the first place. None of the saved money is coming from this shit - shipping and payment costs are unchanged, crypto payment processing is neither cheap nor free (and even if it were, most customers will not being paying in it). > When things go from digital to physical, they typically get 100x more valuable (Walmart to Amazon, Blockbuster to Netflix). This is such an absurd take there's really no response warranted but laughter. These companies had completely different business models. > Imagine buying a new pair of Dunks from your local skate shop, then getting a digital pair same day to throw on your avatar in the Otherside or display them on a shelf in your Meta Horizons social space? Just little ideas. Nobody wants Facebook's metaverse garbage

I think the utility absolutely makes sense. My issue with it is from an engineering perspective. It has no reason to be on a blockchain. There is a centralized issuer creating the tokens. The simpler, more effective, and more efficient solution is a regular old database with an API that can be checked using the unique ID stored in the sneaker’s NFC chip.

No a NFC tag does not provide any legitimate anti-counterfeiting protection. You can just counterfeit the NFC tag...

Newer NFC tags have a lot of security built into them now, although security that is utilizes hardware obfuscation alone has historically been broken.

Comments like yours once again assure me that a lot of people in the "NFT space" have little to no understanding of technology. Do you think modern NFC keycards can simply be copied?

You can be 100% certain that any and all data that sits in that NFC fob can be retrieved.

They are gonna start using these NFC tagged shoes with publicly placed NFC readers to try to track people in real life. This is just one step closer to mass surveillance. Imagine a day where you won't be allowed into a building without NFC shoes to track which rooms you entered. It does solve issues with ship lifting and other things tho.

Yes, I meant billion, as you can see by me dividing 1.8 billion by 365 "million" and getting 0.5%, sorry simple typo. > Everything else you've said up until this point is conjecture or speculation. No, it's an objective fact that a blockchain has zero possible way to monitor the physical world trustlessly. If you disagree, go ahead and name a single way that can happen. > They're also incorporating NFC tags into the physical shoe 1) In my example above where the guy sold the real shoe under the table and a counterfeit with the NFT, he could have simply removed the tags and put them in the counterfeit... 2) What happens if someone does scan a tag at some point, and it doesn't pan out? What are they gonna do? Sue the seller? NFTs have no legal weight. Dude just goes "Dunno man, I bought a pretty shoe from a guy for cash, I don't know anything about NFTs. What's an NFT?" And you're shit out of luck, also the blockchain is now just wrong. > it'll be on ledger and nobody will transact with the owner of that NFT. Also the ledger is anonymous, so this sentence makes no sense. You can't blackball me, because I can just make a new ethereum address in literally 5 seconds and transact from you again 5 seconds after that, with you being none the wiser that I'm the same guy. So....?

>Total shoe industry is 365 million. [You missed a zero. It's a little over 365 BILLION.](https://www.grandviewresearch.com/industry-analysis/footwear-market) Everything else you've said up until this point is conjecture or speculation on the technology. They're also incorporating NFC tags into the physical shoe that points to the on-chain asset. If there's ever a possibility of fraud, then it'll be on ledger and nobody will transact with the owner of that NFT.

NFC spoofing is just as much impossible. Assuming of course it is properly implemented. In the past many low-security use cases only used to unique ID of every NFC chip. And well, those you can simply clone. But exactly like blockchain, a basic secure implementation of NFC will have the NFC tag sign a message with its private key, and then you compare that to the public key. If you think spoofing a secure NFC implementation is not difficult: Try spoofing a contactless payment card ;) . The huge advantage NFC tags have here, is they are inside the product, instead if somewhere completely unrelated to the product, and you just have to trust the seller they actually belong together.

Lol proving your shoe is real by involving an NFC reader is inherently uncool, this technology would just make counterfeits cooler than they already are.

NFC spoofing is not particularly difficult
