Heima is a full-stack coordination protocol that abstracts complexity across accounts, chains, and agents — enabling seamless, verifiable cross-chain execution for users and developers. Through a unified omni-account system, intent-centric execution, and a decentralized Agent Hub, Heima enables users to operate across multiple blockchains without manual bridging, wallet switching, or gas token management. Its architecture leverages a custom Substrate-based Layer 1, account abstraction, omni-executor routing, and programmable automation to deliver a seamless DeFi experience rivaling CEX usability while maintaining decentralization.
