Response

Before construction, the validator checks the account has pending unfreeze entries. The example account has none; the actual Nile response is:

{"Error": "class org.tron.core.exception.ContractValidateException : No unfreezeV2 list to cancel"}

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):

  "txID": "<computed from raw_data>",
