joinmarket-clientserver VS firmware

It's complicated. The more steps you take to obfuscate your transaction, the harder it will be for an adversary to track your coins. You can look into using something like the JoinMarket Wallet to keep your transaction more private.

You can use coinjoin services like joinmarket to anonymize your coins. You can also send them through a lightning swap.

This is a bitcoin service delivered in a low trust manner where the bitcoin user need only utilize software they run and control for the services and can protect themselves from malicious third parties with very little trust or consequence from peers. This is the gold standard of Bitcoin service. Examples include lightning routing, lightning liquidity marketplaces like pool, coinjoins like joinmarket, coinswaps, submarine swaps like loop and others.

If you want to play with OP_CHECKLOCKTIMEVERIFY, you can use the wallet in JoinMarket to create a fidelity bond. Be careful, though, because it's absolutely impossible to spend such a bond until its expiration.

I opened a GitHub issue - https://github.com/JoinMarket-Org/joinmarket-clientserver/issues/1349.

TIP: Use the BoM as well as the schematic.

As you can see, the default firmware of Coldcard is hardcoded with values d13e and cc10. We are going to change it to make it look like a benign USB device, more on it later. First, clone the original firmware from Github: https://github.com/Coldcard/firmware We now need to edit the file called ./stm32/COLDCARD/shared/usb.py: COINKITE_VID = 0xd13e CKCC_PID = 0xcc10

Software altered? You were supposed to download from source and flash it yourself. So why did you alter it? No one other than you could have altered it! https://github.com/Coldcard/firmware

Coldcard

Consider holding long term with a solution like this. Have you ever use a hardware wallet like a coldcard

Coldcard has many other security features as well. You can find more about them online. Probably the safest hard & cold wallet on the market right now. But most people don't buy it because of their $400 price tag. But definitely worth it for anyone holding more than a pretty penny.
