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.

🔹 Secure Key Derivation: Root signers are generated inside TEE from the OmniAccount hash

🔹 Non-Custodial: Users sign with their EOA while smart accounts execute autonomously

🔹 Counterfactual Wallets: Addresses can be used before deployment via initCode in UserOps

🔹 Any ERC-20 Token: No EIP-3009 required — works with any standard ERC-20 via UserOp execution

🔹 Paymaster Support: Optional gasless transactions via the paymasterAndData field

🔹 Multi-Chain: EntryPoint clients configured per chain_id
