Heima is the Substrate-based, EVM-compatible Layer 1 that Litentry became in 2025 after a governance vote. It runs as Polkadot parachain 2013 and executes both WASM and EVM contracts, with EVM chain ID 212013. A single omni-account lets users act on Ethereum, Solana, BNB Chain, and Base from one identity, and omni-executors running in trusted execution environments turn user intents into cross-chain transactions. HEI replaced LIT as the network token.
