A smart Twitter user caught a hack that could have cost Optimism a lot of money on a cross-chain bridge between BitBTC and the Ethereum layer-2 network.
Users can send assets between Optimism’s network and BitAnt’s decentralised finance (DeFi) ecosystem, which includes yield services, non-fungible tokens (NFTs), swaps, and the BitBTC token, where 1 million BitBTC is equal to 1 Bitcoin, using the proprietary cross-chain bridge (BTC).
