By running critical logic inside protected environments, Heima’s TEE infra enables x402 agents to execute and pay programmatically without manual intervention or custodial risk.

đŸ”č Secure Key Derivation: Root signers are generated inside TEE from the OmniAccount hash
đŸ”č Non-Custodial: Users sign with their EOA while smart accounts execute autonomously
đŸ”č Counterfactual Wallets: Addresses can be used before deployment via initCode in UserOps
đŸ”č Any ERC-20 Token: No EIP-3009 required — works with any standard ERC-20 via UserOp execution
đŸ”č Paymaster Support: Optional gasless transactions via the paymasterAndData field
đŸ”č Multi-Chain: EntryPoint clients configured per chain_id
