ZetaChain is a layer 1 blockchain and developer platform that connects any L1 and L2, from Ethereum to Bitcoin and beyond. With ZetaChain you can build interoperable omnichain contracts or use cross-chain messaging between EVM chains. Omnichain Smart Contracts are contracts deployed on ZetaChain that can use and orchestrate assets on connected chains, as well as on ZetaChain. With omnichain smart contracts you are able to have a single place of logic that can maintain the state of assets and data across all connected chains. You can implement cross-chain swaps, staking, lending protocols for Bitcoin or any cross-chain dapps. Cross-chain messaging (CCM) lets you send messages from any connected chain to any connected chain, including ZetaChain. Cross-chain messaging makes the most sense for applications that generally need minimal logic or state to maintain across all chains, and where data that needs only to be passed between different chains one way.
