Diamond Hands just dropped the beta release of Diamond Wallet, the first functional self-custodial Lightning wallet from Japan.
The wallet was built using the Breez SDK's Native (Greenlight) implementation.
It includes a new feature they’ve added called 'sats4ads,' where you can earn sats for watching ads.
Here are some of the key features:
-
You can earn sats through 'sats4ads' — just by watching ads in the app.
-
There’s Bolt Link, which is like bit.ly but with Lightning payments. You click a link, watch an ad, and earn bitcoin. Only users with a Lightning channel can claim rewards, keeping it secure and spam-free.
-
It’s self-custodial, so no third parties holding your funds.
Koji Higashi, the co-founder, mentioned that the regulations in Japan make it difficult to offer custodial services, so going the non-custodial route was the best move.
It’s still in beta, but they’re working on adding more features like in-app channel opening, direct ad delivery, interoperability with other wallets, as well as a referral program.
The Diamond Hands team shared a demo on X as well as this blog sharing more details on what they've built. They've also shared more technical details on their GitHub.
If you’re into testing out new stuff, you can find it on Google Play and Apple TestFlight.
