No problem at all. You’ll help me improve the tutorial. 😄

The purpose of Blue Wallet (and the other options listed) is to sign a configuration message linking your OCEAN Bitcoin address with the BOLT12 offer.

So you can use a Bitcoin address from any wallet, but that wallet needs to also support signing.

Coinos just added signing functionality but it still needs to be tested. I can confirm only confirm Blue Wallet at the moment. 🫡
