The miner fees in TRX wallets have generally increased as a result of TRON changing the energy charging mechanism to a dynamic energy model.
To avoid failed transactions during transfers and exchanges in the TRX wallet, ensure the current address has a minimum of 50 non-staked TRX or 3,000 staked TRX to get enough energy to cover the miner fee.
In order to enhance user experience, imToken will add a miner fee estimation feature for TRX wallet in the future, making it easier for users to view required fees before initiating transactions.
Note: The miner fee is charged by the TRON network and is non-refundable, so it's crucial to have enough TRX in the wallet to pay for it. imToken doesn't charge any fees.
