Today is a huge day for Stacks and the broader Bitcoin ecosystem! The mainnet release of sBTC is here, introducing Bitcoin deposits that allow users to mint sBTC on the Stacks layer.

This post covers the key features of sBTC that are available now, a refresher on the continued rollout to follow, and how to participate in the sBTC incentive program and earn ~5% in annual Bitcoin rewards, paid in sBTC.
sBTC with Bitcoin Deposits
This initial phase of sBTC introduces deposit functionality, allowing users to start minting sBTC and participate in the ecosystem. Future iterations will introduce withdrawals and transition to a fully decentralized system, further reducing trust requirements. Today’s sBTC’s release opens with a 1,000 BTC cap which will gradually be increased to onboard more users.
Key sBTC Features Available Now
  • Bitcoin Deposits: Users can start minting sBTC now.
  • 1:1 Bitcoin Backing: sBTC maintains a 1:1 peg with Bitcoin, ensuring the integrity of users' assets.
  • Institutional Signer Network: A set of 15 community-elected Signers reduces single-entity trust. In 2025, sBTC will be moving towards a fully open, permissionless Signer network.
  • 100% Bitcoin Finality: Leveraging the recent Nakamoto upgrade, sBTC transactions are as secure as Bitcoin itself.
  • Transparent, Open-source Code: Ensuring trust and allowing for community scrutiny and improvement.
What’s next for the sBTC rollout
The sBTC rollout is structured in multiple phases to ensure security, usability, and scalability. Over the coming weeks, as more users, builders, and investors are onboarded to the sBTC protocol, core developers will continue working towards Bitcoin withdrawal functionality and further decentralization of the system.
