## The memo

REJECTED. Babylon lets a BTC holder lock native Bitcoin in a self-custodial, timelocked UTXO to provide economic security to proof-of-stake chains, without bridging — a real technical innovation using Bitcoin script and extractable one-time signatures to enforce slashing only through the consequence of a finality provider's double-signing, never by trusting a bridge custodian with the BTC itself. But the standing facts here are disqualifying regardless of that design quality: DefiLlama's own protocol record lists zero registered security audits for Babylon, and this review could not independently confirm one exists elsewhere. Tracked TVL peaked near $7.1B in October 2025 and has since fallen to roughly $2.6-2.8B, a decline of about 60% that outpaces plausible BTC price movement alone. The BABY governance token is down roughly 94% from its April 2025 all-time high, hitting a fresh all-time low three days before this review. The covenant committee's membership and threshold, and the concentration of stake across finality providers, are both undisclosed in public documentation. This entry is reviewed on a 30-day cycle given the active drawdown.

## What would reopen the file

- A confirmed, primary-source independent security audit of the Babylon staking protocol is published
- The covenant committee's membership, threshold, and any change process are publicly disclosed
- Finality-provider stake concentration is disclosed and shown to be reasonably diversified
- TVL and the BABY token stabilize for a sustained period following the documented drawdown
