​
Parameters

  • owner_address — the address performing the token swap (base58 with visible: true, or hex with visible: false).
  • exchange_id — unique identifier of the exchange pair to trade on.
  • token_id — token ID being sold; use _ to denote TRX.
  • quant — integer amount being sold (token base units; if TRX, specify in sun).
  • expected — integer minimum to receive (token base units; if TRX, sun). Protects against slippage.
  • permission_id — optional permission ID for multi‑signature accounts.

​
Response

Returns a transaction object containing:
  • txID — unique transaction identifier
  • raw_data — raw transaction data including contract details
  • raw_data_hex — hexadecimal representation of raw transaction data

​
Use case

The wallet/exchangetransaction method is used for:
  • Swapping tokens directly on the TRON decentralized exchange
  • Converting between TRX and TRC20 tokens at current market rates
  • Building arbitrage bots and automated trading strategies
  • Implementing token exchange functionality in decentralized applications

  • amounts must be integers (do not quote numbers). If TRX is involved (token_id is ”_” on either side of the pair), express TRX values in sun (1 TRX = 1,000,000 sun).
  • the call returns an unsigned transaction; sign and broadcast it. On mainnet, the exchange must exist and you must have sufficient balance; slippage protection may reject if market has moved.
