Heima enables seamless interaction across multiple blockchains through an intent-centric execution model, removing the need for users to manually manage chain-specific operations or gas payments.

At the heart of this model is the omni-executor, a TEE-secured execution environment that interprets user intents and fulfills them via optimal cross-chain routes.

When a user submits an intent (e.g., “swap token A for token B at the best price”), Heima automatically determines how and where to execute it, abstracting away the underlying blockchain complexities.

Key Features:

  • Intent-Based Execution

    Users express desired outcomes rather than defining transaction steps. The system determines the optimal routing and execution strategy across chains.

  • Gas Abstraction

    Users can pay transaction fees with any supported token across any network. Gas management and token conversions are handled automatically behind the scenes.

  • Modular Architecture

    Transaction composition, cross-chain routing, and signature validation are decoupled into independent services.

    This enables flexible implementation strategies, from low-cost off-chain RFQ matching to trust-minimized on-chain DEX fulfillment, depending on user priorities.

  • Layer 1 Anchoring

    All execution steps are recorded and validated on Heima Layer 1, ensuring full traceability, verifiability, and auditability.


Heima’s chain abstraction infrastructure is designed to be production-ready, supporting complex DeFi workflows while preserving a simple and transparent user experience.

Through this intent-based system, users simply define what they want to achieve, while Heima coordinates execution securely and efficiently across multiple chains.
