1inch Network unites decentralized protocols whose synergy enables the most lucrative, fastest and protected operations in the DeFi space. The initial protocol of the 1inch Network is a DEX aggregator solution that searches deals across multiple liquidity sources, offering users better rates than any individual exchange. This protocol incorporates the Pathfinder algorithm which finds the best paths among different markets over 180 liquidity sources on Ethereum, BNB Chain, Polygon, Avalanche, Optimistic Ethereum, Arbitrum and Gnosis Chain. In just over two years the 1inch DEX aggregator has reached 2M users and surpassed $150B in overall trading volume. The 1inch Aggregation Protocol facilitates cost-efficient and secure swap transactions across multiple liquidity sources.

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.
