FAQ

When will sBTC be available?

sBTC deposits will be available on the mainnet starting December 17, 2024, with withdrawals expected in March 2025.


Full decentralization of the Signer set will follow in a subsequent phase, gradually expanding beyond the initial 15 community-elected signers.

What sets sBTC apart?

Here are the main differentiating characteristics of sBTC:
‍

  • sBTC is a true Bitcoin native product
  • sBTC is backed by respected leaders in the Bitcoin community (signer network)
  • sBTC’s security is provided by a decentralized network of validators/signers, rather than a single custodian, removing the need to trust a single entity or exchange
  • sBTC leverages 100% Bitcoin finality
  • sBTC’s technology offers optimal UX and DevEx for an L2
  • sBTC is a fully transparent project/product working in the open with public code

What security measures have been put in place to ensure sBTC is safe?

Partnerships with top-tier security experts have been established to ensure the protocol is fortified at every level:

  1. Asymmetric Research: Known for their rigorous research and protocol audits, Asymmetric brings security expertise to sBTC to identify and mitigate potential vulnerabilities.
  2. ImmuneFi: A robust bug bounty program incentivizes ethical hackers to uncover and address potential issues, adding an additional layer of defense.
  3. 3rd Party Audits: Independent audit reports will be completed for additional security reviews, ensuring the protocol is thoroughly vetted by external experts.

What wallets are supported for sBTC?

Xverse and Leather wallets are supported — two leading wallets with seamless integrations designed for Bitcoin and Stacks users.
‍

We are actively working with institutional custodians, staking providers, and other 3rd party wallets to support sBTC. More will be announced.

  1. Ensure BTC is accessible via one of the following non-custodial wallets: Leather and Xverse.
  2. To interact with the sBTC protocol and mint sBTC, head to the sBTC Dashboard and connect your non-custodial wallet with BTC ready to deposit.
  3. Enter the BTC amount to convert to sBTC.
  4. Enter your Stacks receiving address to initiate the transfer.
