ColdQR

@SeedEtcher The shop will soon be ready! Until then, feel free to shop at our resellers which are linked on the website.

@ColdQR I wonder how much they cost. Safari on iPhone won’t tell me.

Hello world!

@BatscheBatsche It's almost a shame to stamp these, but it has to be done!

Check out these beauties !

@TheBTCGame @SeedSigner @selfcustodykrux @FOUNDATIONdvcs @BlockstreamJade @KeystoneWallet Yes, a black fine tip marker did the trick. But to be honest, our final production batch even scanned without blackening the marks, but this depends on the lightning conditions.

@ColdQR @SeedSigner @selfcustodykrux @FOUNDATIONdvcs @BlockstreamJade @KeystoneWallet Pretty and functional! Curious, in this image, did you fill the punched holes with black somehow?

At 5.5 mm thick, this is not a flimsy plate. It is a solid titanium backup you punch with your Compact SeedQR, creating a permanent, airgapped, instantly scannable recovery for your Bitcoin keys. ColdQR. The physical form of your digital keys. Scan it directly with your hww!

@jamie_donald Thanks! Likewise for single sig with a BIP39 Passphrase, but we prefer multisig too.

@ColdQR Looks great. Awesome for a multisig with SeedSigner
