Evolved from Litentry, Heima Network is a substrate-based, EVM-compatible L1 that connects to a Polkadot-class relay chain for shared security and interoperability. It is built for chain abstraction and cross-chain operations, with:

• HEI token — the native token: transfers, governance, staking.
• Runtime & pallets — omni-account (cross-chain account abstraction), parachain-staking, omni-bridge, TEE worker registration (teebag), extrinsic filtering, and full EVM support.
• omni-executor — a TEE (Gramine/SGX) worker that executes cross-chain UserOperations (EIP-4337 account abstraction) across Ethereum, Solana and other chains.

Repository layout

• parachain/ — the node, runtimes (heima, paseo) and pallets.
• tee-worker/omni-executor/ — the cross-chain TEE worker.
• local-setup/ — helper scripts for local development.

All commands below are run from the repository root unless noted otherwise.

Parachain

The parachain ships two runtimes: heima-runtime (paraID 2013) and paseo-runtime (paraID 2106, for the Paseo testnet), both produced by the heima-node binary.

Build

make build-node                 # build the heima-node binary
make build-runtime-heima        # build the heima runtime wasm
make build-runtime-paseo        # build the paseo runtime wasm

Runtime wasms land under parachain/target/release/wbuild/<runtime>/.

To build the litentry/heima docker image (by cargo profile):

make build-docker-release       # `release` profile
make build-docker-production    # `production` profile

Launch

Spin up a local network (2 relaychain validators + 1 collator) with zombienet:

make launch-network-heima       # or: make launch-network-paseo

Once it is up, the chain is reachable in the polkadot-js explorer at ws://127.0.0.1:9944. Tear it down with:

make clean-network

For faster iteration, run a single standalone node (no relaychain, instant block finality):

make launch-standalone

Test

make test-cargo-all             # cargo tests across the workspace
make test-ts-heima              # TypeScript integration tests (or: test-ts-paseo)

The TypeScript suite lives in parachain/ts-tests/.

omni-executor

omni-executor is a Rust TEE worker (running under Gramine/SGX) that executes cross-chain UserOperations — EIP-4337 account abstraction — across Ethereum, Solana and other chains, exposing a JSON-RPC server for authenticated submissions.

It vendors its Solidity dependencies as git submodules, so initialize them first:

git submodule update --init --recursive

Build

cd tee-worker/omni-executor
cargo build --release           # host build, for local development
make SGX=1                      # build & sign for Gramine/SGX

Run locally

A docker-compose setup brings up the worker together with a local Anvil EVM node and auto-deployed account-abstraction contracts. From tee-worker/omni-executor/:

make build-docker               # or: make build-docker-test (with test endpoints)
make start-local                # or: make start-test
make stop-local                 # tear down (or: make stop-test)

Test

TypeScript integration tests live in tee-worker/omni-executor/ts-tests/.
