Summary
Ketju does not approve Lorenzo enzoBTC: we could not confirm from primary sources how or when holders redeem, how many custodians must approve a transfer, or who can pause or freeze the contracts. We found no defect. Without these basic facts, though, Ketju cannot approve a position. enzoBTC is Lorenzo Protocol’s omnichain wrapped-BTC token. Users can mint it from native BTC, WBTC or BTCB, and three named custodians hold its backing. enzoBTC also depends on LayerZero and Wormhole, two messaging layers that Ketju does not approve. It shares a named custodian, Cobo, with Function FBTC, which Ketju also does not approve. A client who holds both may think the two are diversified when they share that custodian.
