Heima: The Chain Abstraction Protocol for Cross-Chain DEX Trading

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.

Managing assets across different networks today requires manual bridging, wallet switching, and constant gas token management — all of which lead to poor user experience, high friction, and security risks.

Heima solves this by introducing a unified omni-account system, an intent-centric execution framework powered by the Omni Executor, and a decentralized Agent Hub.

With Heima, users interact through a single interface that abstracts away the complexities of underlying blockchains. Behind the scenes, the system computes optimal execution routes, sources liquidity, and fulfills intents through a decentralized execution framework secured by Trusted Execution Environments (TEEs).

This architecture allows users to operate across chains without switching wallets, manually bridging assets, or managing native gas tokens — enabling seamless and verifiable automation for cross-chain DeFi workflows.

Developers benefit from a programmable automation framework that supports delegated execution and enables custom automation strategies. On EVM chains, Heima offers EOA compatibility via EIP-7702 — allowing seamless integration with existing wallets without infrastructure overhaul. Heima supports both on-chain and omni triggers, enabling a new design space for building cross-chain DeFi protocols, wallets, dApps, and infrastructure primitives.

From unified balances and gasless transactions to chain-agnostic smart contract interactions, Heima provides the foundation for building decentralized applications that operate across multiple chains as if they were one unified environment.

Vision

Heima aims to solve these problems by delivering a seamless, cross-chain DeFi experience that rivals CEX usability while maintaining decentralization.

Architecture Overview

Heima is made up of four core module work in unison to deliver seamless coordination, universal access, and programmable automation across multiple blockchain ecosystems. They include:

---

1. Heima Network (Layer 1)

Heima network is a custom Layer 1 blockchain built on Substrate. This network serves as the coordination layer for intents, agents, and cross-chain execution. It anchors all user intents, manages agent registration, governs network parameters, and provides a secure, verifiable ledger of cross-chain activity. Through built-in scheduling, governance, and event systems, the Heima Network ensures high throughput, deterministic execution, and public auditability of all cross-chain workflows.

2. Account Abstraction (Omni-account)

Heima eliminates wallet fragmentation by introducing omni-account, a new account primitive that unifies Web2 and Web3 identities. Users can authenticate using email, passkeys, or any standard Web3 wallet. Behind the scenes, Heima leverages:

• EIP-7702 for EVM compatibility

• Substrate proxy accounts for native integration

• TEE-secured accounts to abstract non-native chains

This design enables a seamless login experience and allows users to control assets and activity across chains through a single account interface.

3. Chain Abstraction (Omni-Executor)

The omni-executor interprets and routes user intents such as swaps, transfers, or staking across any supported chain. It dynamically computes optimal execution paths, handles cross-chain messaging, manages gas abstraction, and ensures final settlement. All execution data is anchored back to the Heima Network for traceability. This layer decouples user experience from the underlying blockchain logic, enabling gasless, unified, and transparent operations.

---

4. Agent Hub

Heima enables decentralized, programmable automation through the Agent Hub, a permissionless network of bots and execution agents. These agents monitor conditions (on-chain and omni), fulfill user intents, and execute arbitrage, rebalancing, staking, or complex workflows. Agents are incentivized through built-in reward systems, staking mechanisms, and performance-based rebates.

Open, Extensible, and Composable

Heima is built with developers and integrators in mind. The system supports:

• custom signers, intent fillers, and execution logic

• External routers and automation logic

• Rebate and monetization layers for service providers and partners

Whether you're building an omni-chain DEX, wallet, GameFi automation, identity protocol, or complex dApp, Heima provides the infrastructure to deploy secure, scalable, and intent-driven applications.
