Chain ID 56Account delegate
Third-party, not ours: eth-infinitism's canonical Simple7702Account v0.9 implementation, which is the code an EIP-7702 account adopts. A delegated account's on-chain code is the 0xef0100 prefix followed by this address, which is what GET /account/delegation-status reports as the delegate. UGTP verifies the runtime bytecode at this address against the approved implementation before it builds an operation for the account.

Chain ID 56Avalanche executor
Executes an account-signed EIP-712 execution request on Avalanche C-Chain, where EIP-7702 does not exist. It pulls the ERC-20 fee against an allowance the account granted once, so it moves nothing the account has not approved for it.
