Parameters

  • owner_address — the address that owns the TRX to freeze (hex format)
  • frozen_balance — the amount of TRX to freeze (in sun, where 1 TRX = 1,000,000 sun)
  • frozen_duration — the duration to freeze for (minimum 3 days)
  • resource — the resource type to obtain (“BANDWIDTH” or “ENERGY”)
  • receiver_address — optional address to receive 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
  • raw_data — raw transaction data object
  • raw_data_hex — hexadecimal representation of raw transaction data

​
Use case

The wallet/freezebalance method is used for:
  • Staking TRX to obtain bandwidth for free transactions (legacy method).
  • Freezing TRX to get energy for smart contract execution (legacy method).
  • Supporting older applications that still use the original staking mechanism.
  • Migrating from the deprecated staking system to the new freezebalancev2 method.
