Why a USDT TRC20 transfer burns TRX: Tron energy and bandwidth explained
Tron charges for transfers in its own way. Here is what energy means, why your USDT send used up TRX and how to pay less.
Most blockchains simply charge a fee in their native coin. Tron is a bit different. Every transaction draws on two resources: bandwidth and energy. Plain TRX transfers mostly use bandwidth, and each account receives a small free allowance of it every day. Token transfers such as USDT use energy, and energy is where the cost is.
Ways to get energy
- Burning TRX. Without energy, the network burns TRX from your wallet to pay for it. This is what most people run into.
- Staking TRX. Stake TRX and you get energy that recharges over time. Handy if you send USDT regularly.
- Renting energy from a marketplace, which can cost less than burning when you only send now and then.
Useful habits
- Hold some TRX in every wallet that holds USDT TRC20. Without it, you cannot send.
- A transfer to a new address that has never held USDT uses more energy than one to an address already in use.
- Look at the cost estimate in your wallet before you confirm.
What this means for a swap
If a swap sends you USDT TRC20, we cover the cost of that transfer. If you deposit USDT TRC20 into a swap, the cost comes from your wallet, so make sure you have TRX on hand. Want to skip all of this? Swap your USDT into TRX on Swap1337 first. More on the TRX overview.
Quick answers
Is TRX required to receive USDT TRC20?
No, receiving costs nothing. You only need TRX, or energy, when you send USDT out of your own wallet.
Why was one USDT send more expensive than another?
A transfer to an address that has never held USDT takes more energy than a transfer to one that already has. The gap can be noticeable.
