  • second_token_id — TRC10 token ID of the second token; use _ to denote TRX.
  • second_token_balance — initial amount for the second token as an integer (if TRX, specify in sun).
  • permission_id — optional permission ID for multi‑signature accounts.

​
Response

Returns a transaction object containing:

  • balances must be integers (do not quote numbers). When the second token is TRX (denoted by _), provide second_token_balance in sun (1 TRX = 1,000,000 sun).
  • use _ for TRX or a TRC10 token ID string for both sides to create TRC10–TRC10 pairs.
  • the call builds an unsigned transaction; you must sign and broadcast it. On mainnet, additional on‑chain validations apply (token existence, ownership, pair uniqueness, sufficient balances).
