  "owner_address":    "41dd791d6b49e190062d650e6a23c575510d35f2f9",

Response

Before construction, the servlet validates that owner_address matches the contract's origin_address (deployer). The example owner_address is not the TetherToken deployer; the actual Nile response is:

{"Error": "class org.tron.core.exception.ContractValidateException : Account[41dd791d6b49e190062d650e6a23c575510d35f2f9] is not the owner of the contract"}

When validation passes, returns an unsigned protocol.Transaction. Structure outline (txID / ref_block_* / expiration / timestamp / raw_data_hex semantics are the same as /wallet/createtransaction):
