Diamond Wallet: Lightning Wallet with Bolt Link & sats4ads Functionality "We have about 200 testers from Japan now. With the beta release, we'll slowly expand to other markets, add important features like credit card channel opens, improve UI/UX etc. Lots to build but we're not in a rush and committed to pursuing the self-custody path." https://www.nobsbitcoin.com/diamond-wallet-beta/
