​
Response

  • visible — boolean indicating whether addresses are in visible format
  • txID — unique transaction ID for the witness creation transaction
  • raw_data — raw transaction data containing:
    • contract — array with witness creation contract details
    • ref_block_bytes — reference block bytes for transaction validation
    • ref_block_hash — hash of the reference block
    • expiration — transaction expiration timestamp
    • timestamp — transaction creation timestamp
  • raw_data_hex — complete transaction data encoded in hexadecimal format

​
Use case

The wallet/createwitness method is used for:
  • Registering an account as a witness to participate in TRON network governance.
  • Setting up block production capabilities for earning rewards from the network.
  • Establishing a public presence for community voting and trust building.
  • Preparing to compete for one of the 27 Super Representative positions.
  • Contributing to network security and decentralization through validation services.
  • Building reputation and credibility within the TRON ecosystem.
This method only creates the witness registration transaction. You must sign the transaction and use wallet/broadcasttransaction to complete the witness registration. Becoming an active block producer requires receiving votes from TRX holders.
