CromaChain is a Layer 2 blockchain solution that combines AI-assisted smart contract development, cryptography, and consensus mechanisms to support scalable decentralized applications. It processes transactions using a DAG structure with zk-STARKs for verification, achieving transactions, while integrating EigenDA for data availability and zkEVM compatibility for Ethereum-based tools. The system enables natural language prompts to generate and deploy smart contracts, provides a cross-chain zkBridge for asset transfers, and maintains low fees.
