TRON API method that unstakes TRX previously frozen for bandwidth or energy resources (deprecated method). This method releases TRX tokens that were previously frozen, making them available for transfer after the lock period expires. Note that this is the legacy unstaking mechanism, replaced by unfreezebalancev2.

  • owner_address — the address that owns the frozen TRX to unfreeze (hex format)
  • resource — the resource type to release (“BANDWIDTH” or “ENERGY”)
  • receiver_address — optional address that was receiving the resources (defaults to owner_address)
  • visible — optional boolean to specify address format (default: false for hex format)

​
Response

  • visible — boolean indicating address format used
  • txID — transaction ID hash

​
Use case

The wallet/unfreezebalance method is used for:
  • Unstaking TRX to make tokens transferable again (legacy method).
  • Releasing bandwidth or energy resources that are no longer needed (legacy method).
  • Supporting older applications that still use the original unstaking mechanism.
  • Migrating from the deprecated unstaking system to the new unfreezebalancev2 method.
