A cross-chain bridge between BitBTC and the Ethereum layer-2 network Optimism has been able to avoid a potentially costly exploit thanks to the work of an eagle-eyed Twitter user.
The custom cross-chain bridge offers a ramp for users to send assets between Optimism’s network and BitAnt’s decentralized finance (DeFi) ecosystem, which includes yield services, nonfungible tokens (NFTs), swaps and the BitBTC token, in which 1 million BitBTC represents 1 Bitcoin (BTC).
