Summary
Ketju does not approve Babylon Protocol: we could find no security audit of it, and its TVL and token have fallen steeply. Babylon lets a holder lock native Bitcoin in a self-custodial, timelocked UTXO to help secure proof-of-stake chains, with no bridge. It uses Bitcoin script and extractable one-time signatures, so a staker’s BTC is slashed only when a finality provider double-signs. No bridge custodian ever holds the BTC. The design is a real technical advance, but other facts rule Babylon out. DefiLlama lists zero security audits for Babylon, and we could not confirm one elsewhere. Tracked TVL peaked near $7.1B in October 2025 and has fallen to roughly $2.6-2.8B. BTC’s price alone does not explain that drop of about 60%. The BABY token is down roughly 94% from its April 2025 high and hit a new low three days before our review. Public documents do not disclose the covenant committee’s members and threshold, or how stake is spread across finality providers. Ketju reviews this memo every 30 days while the drawdown continues.
Review triggers
- 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 after the documented drawdown
