TRON API method that creates a transaction to deploy a new smart contract to the TRON network. This method prepares the deployment transaction with all necessary parameters, which must then be signed and broadcast to complete the contract deployment.

​
Parameters

  • owner_address — address of the account deploying the contract in hexadecimal format
  • abi — contract ABI (Application Binary Interface) as a JSON string defining contract methods and events
  • bytecode — compiled contract bytecode in hexadecimal format
  • parameter — (optional) constructor parameters encoded in hexadecimal format
  • call_value — (optional) amount of TRX to transfer to the contract during deployment (in SUN, 1 TRX = 1,000,000 SUN)
  • consume_user_resource_percent — (optional) percentage of caller’s resources used for contract calls (0-100, default 100)
  • fee_limit — (optional) maximum energy fee willing to pay for deployment (in SUN)
  • origin_energy_limit — (optional) energy limit provided by the contract creator for future calls
  • name — (optional) human-readable name for the contract

​
Response

  • visible — boolean indicating whether addresses are in visible format
  • txID — unique transaction ID for the deployment transaction
  • raw_data — raw transaction data containing all deployment parameters
  • raw_data_hex — raw transaction data encoded in hexadecimal format

​
Use case

The wallet/deploycontract method is used for:
  • Deploying new smart contracts to the TRON blockchain.
  • Creating TRC20 tokens, NFT contracts, and other decentralized applications.
  • Setting up contract resource limits and fee structures during deployment.
  • Preparing deployment transactions that can be signed offline for security.
  • Building deployment tools and contract management platforms.
  • Establishing smart contract infrastructure for DApps and services.
This method only creates the deployment transaction. You must sign the transaction and use wallet/broadcasttransaction to actually deploy the contract to the network.
