BOB
BOB ("Build on Bitcoin") is a hybrid Layer-2 powered by Bitcoin and Ethereum. By combining the security, liquidity, userbase, and innovation of the two largest blockchain ecosystems, BOB aims to close the gap between Bitcoin as a vehicle for mass adoption and Ethereum as a hub for innovation.
FusionLock audit
Common Prefix was commissoned to perform a security audit of BOB's FusionLock contract, where users can lock tokens. Upon a specified time (determined by the contract owner), users can either withdraw the tokens or bridge them to BOB using a bridge like Optimism's. We also ensured compatibility with the bridge by reviewing the list of tokens permitted to be locked in the contract.
Onramp audit
Common Prefix was commissoned to perform a security audit of BOB's Onramp smart contracts, facilitating users' onboarding onto the BOB L2 network without the need to hold any Ethereum assets beforehand.
