Research summary
Our research supports rejecting uniBTC for this advisor sleeve. It adds an upgradeable, multichain liquid-restaking wrapper to Bitcoin custody and has already suffered the exact minting risk that wrapper holders bear. In September 2024, an externally callable vault path treated ETH as native BTC and minted 30.8 unbacked uniBTC, causing roughly $2M of DEX-liquidity loss across a vulnerability deployed on eight chains. Later audits and Chainlink Proof of Reserve/Secure Mint controls are meaningful fixes, but they do not justify replacing native BTC with a restaking and bridge claim.
Observable review triggers
- uniBTC completes 24 consecutive months without a mint, reserve, bridge, or redemption incident after Secure Mint deployment
- Independent attestations reconcile every uniBTC liability by chain to reserves and disclose all custodians and encumbrances
- A proposed-size conversion to native BTC completes within a published service level under stressed secondary liquidity
- Any reserve-feed bypass, unbacked mint, bridge compromise, or redemption pause opens an immediate review
