sBTC is a 1:1 Bitcoin-backed asset that lives on the Stacks blockchain. It’s designed to bring the full power of smart contracts to Bitcoin, without compromising trust or decentralization.

With sBTC, users can:

  • Mint sBTC by locking BTC using a decentralized peg mechanism secured by the Stacks Signer network
  • Use it across apps and smart contracts built on Stacks
  • Earn yield, provide liquidity, and trade like any other on-chain token Unlike centralized wrapped Bitcoin tokens, sBTC is secured by Stacks Signers and maintained via a decentralized protocol with peg-in/peg-out flows.

Leather will supports sBTC visibility and eventually allow users to manage sBTC as easily as they manage STX or BTC today. Leather also sponsors transactions for minting sBTC if users do not have STX in their wallet for network transaction fees.

sBTC is a third-party protocol asset not operated by Leather. Users should review the protocol’s documentation before use.
