Heima Network

Heima is a full-stack chain abstraction protocol that lets users interact with multiple blockchains through a single unified account. The project addresses a persistent problem in multichain DeFi: that accessing liquidity on Ethereum, Solana, BNB Chain, Base, Tron, Blast, and other networks requires separate wallets, separate gas balances in each network's native token, and manual bridging between them. Heima abstracts all of that away, presenting users with one account, one balance view, and the ability to pay fees in whatever token they already hold.

From Litentry to Heima

Heima is the rebranded successor to Litentry, a decentralized identity protocol that launched in 2020 within the Polkadot ecosystem. Litentry built infrastructure for aggregating on-chain identity across networks, giving it deep experience in privacy-preserving cross-chain computation. After years operating as an identity layer, the team concluded that cross-chain abstraction represented a larger opportunity and a more direct path to mainstream DeFi usability.

The pivot was approved by the community through Referendum #38 in Litentry's governance system, announced January 20, 2025. The token swap from LIT to HEI at a 1:1 ratio completed on February 10, 2025, with Binance, Bitget, and other centralized exchanges handling the migration for users who held tokens on those platforms. Old LIT tokens are burned when swapped.

Four-Pillar Architecture

The Heima system rests on four interdependent components.

Heima Layer 1 is a Substrate-based blockchain that acts as the registry and settlement layer for the entire protocol. Because it uses the Substrate framework (the same foundation as Polkadot and its parachains), it inherits WASM and EVM compatibility, native governance modules, and runtime upgradeability without requiring hard forks. The network targets 500-millisecond block times. Every execution — whether an intent is fulfilled, an agent completes a task, or a cross-chain route is settled — is recorded on this chain, giving the system an auditable trail of all activity across all supported networks.

Omni-Account (Account Abstraction) replaces the model of one wallet per chain with a single identity that spans all supported blockchains. Users can log in with email, passkeys, or existing social accounts rather than managing seed phrases. Under the hood, the system deploys EIP-7702 proxy contracts on EVM-compatible chains and native proxy accounts on Substrate chains, all controlled through the unified identity. Omni-accounts support delegated operation, meaning users can grant permissioned execution rights to agents or applications without handing over private keys.

Chain Abstraction handles the mechanics of cross-chain execution. Rather than executing individual transactions, users express intents — desired outcomes such as swapping a token on Ethereum for a token on Solana at the best available rate. An omni-executor running inside a Trusted Execution Environment (TEE) evaluates the intent, identifies the optimal execution path across liquidity pools and bridges, and executes the sequence without requiring any user action beyond the original intent submission. Gas fees are sponsored by intent fillers — third parties who execute intents and earn rewards for doing so — so users never need to hold HEI or any chain's native gas token to transact. SMPC (Secure Multi-Party Computation) is used alongside TEE to secure omni-account key material. Off-chain execution in TEE environments emits cryptographic proofs back to the Layer 1, preserving auditability even when computation happens off-chain.

Agent Hub is a permissionless marketplace where autonomous agents register capabilities and offer services. Agents can access live on-chain data through Heima's APIs, integrate off-chain signals, and execute strategies on behalf of users. Participation is backed by staking-based guarantees, and agents earn through rebate models tied to usage. The hub is designed for trading bots, arbitrage agents, and automated position managers to operate across chains without custom infrastructure for each network.

Products and Integrations

The primary consumer product is a cross-chain trading interface that aggregates liquidity across supported networks and automatically routes to the best price. As of mid-2025, Heima reported 52,000 users and over 7.1 million total transactions processed through the platform.

AgentKeys is a newer product that extends omni-account capabilities to paired devices. A paired device holds its signing key locally, receives a scoped channel permission, and can send text, voice, and task requests through a shared permissioned path to an isolated agent environment. This enables flows where a user's device can trigger on-chain actions through an agent without the user directly managing transactions.

Wildmeta is the project's agentic trading and strategy execution platform, designed for automated position management across chains.

PumpX, a Solana-based meme token DEX, serves as the most documented integration case study in Heima's whitepaper. After integrating Heima's abstraction layers without rewriting its core trading logic, PumpX could accept payment in USDT, BNB, ETH, or other tokens from any supported chain for trades that settle on Solana, with gas management handled automatically and cross-chain routing directing orders to the cheapest available market.

HEI Token

HEI is the native token of the Heima ecosystem, with a maximum supply of 100 million. The token supply was targeted to reach full circulation within 20 months of the February 2025 swap. Distribution includes an ecosystem wallet allocation of 22.1 million tokens, a liquidity reserve of 5 million, a foundation allocation of 2.2 million, and a team allocation of 4.25 million subject to vesting. HEI serves three functions: governance participation through multi-layered proposal and referendum mechanisms; mediation asset in cross-chain liquidity pools, where it reduces bridging costs and slippage for user-deployed pools; and staking to secure the agent hub. Users themselves never need to hold HEI directly — intent fillers sponsor gas costs and earn operational rewards from the protocol.

Ecosystem Position

Heima occupies a cross-ecosystem position: built on Substrate with roots in Polkadot, but targeting EVM chains, Solana, Tron, and BNB Chain as the primary markets for its abstraction infrastructure. For Solana specifically, Heima routes cross-chain trading flows to Solana liquidity when it represents the best price or cheapest execution, and the PumpX integration demonstrates how Solana-native applications can adopt Heima's SDK to accept liquidity and user accounts from other networks without rebuilding their core logic.

The team inherited its technical depth from Litentry's years building TEE-based privacy infrastructure within the Polkadot ecosystem, and the protocol's security model — TEE-secured execution with cryptographic proofs anchored on-chain — reflects that background.
