I built a wallet app that sends sBTC using bitcoin addresses instead of Stacks addresses. That's layer 2 sats sent from bitcoin address to bitcoin address in seconds for < $0.01 via the Stacks network: ✅Standard bitcoin addresses ✅Standard sign and broadcast semantics ✅Confirmation in seconds ✅Low fees ✅Self-custody ✅Bitcoin finality While this wallet is a prototype that works only with native Segwit addresses and requires or Leather - Grow your Bitcoin for transaction signing, Bitcoin addresses for sBTC (or all Stacks assets) could be adopted natively by any wallets. It doesn't require any changes to the Stacks core network. This address scheme could even be expanded so that fast, easy and cheap layer 2 BTC transactions could also work with legacy addresses. Here's how it works: Bitcoin legacy and native segwit addresses along with Stacks addresses all encode the so-called "hash160" of the user's public key. This means we can convert these two types of bitcoin addresses into a Stacks address and any Stacks address into either a legacy or native segwit bitcoin address. Using bitcoin addresses instead of Stacks addresses allows us to reuse many of the payment standards and QR code formats that have already been developed for bitcoin. It makes sBTC a true layer 2 bitcoin.
