ST
sBTC is a SIP-010 token on the Stacks blockchain that represents Bitcoin in a 1:1 ratio. The peg is maintained by a federated set of Stackers — STX holders who post stake to participate in sBTC custody — using Stacks’s distinctive Proof-of-Transfer consensus.
The goal is to give Bitcoin holders programmable Bitcoin without relying on a centralized custodian, while remaining anchored to the BTC base layer. sBTC is a key piece of Stacks’s roadmap toward a Bitcoin-aligned smart-contract layer.
