Understanding Tron Bandwidth

What is Bandwidth?

Bandwidth measures the size of transactions stored on the Tron blockchain, counted in bytes. Every transaction consists of three parts: raw_data (sender and recipient addresses, transaction details), a cryptographic signature (~67 bytes), and a result field (~64 bytes). One byte of transaction data equals one unit of bandwidth.

Free Daily Bandwidth

Every activated Tron account receives 600 free bandwidth units per day, automatically and without any staking. This is enough for approximately two TRX transfers (~268 bandwidth each) or one USDT transfer (~345 bandwidth). The free allowance resets every 24 hours.

Transaction Size Examples

TRX transfer: ~268 bandwidth
USDT (TRC-20) transfer: ~345 bandwidth
Resource delegation: ~283 bandwidth

Note: USDT transfers also require energy (a separate resource). Bandwidth alone is not enough for TRC-20 transfers.

Getting More Bandwidth: Staking vs. Burning

Staking TRX — Freeze TRX specifically for bandwidth (separate from energy staking). Your share is calculated as: (your staked TRX / total network staked for bandwidth) × 43,200,000,000. At current rates, 1 TRX staked yields about 1.6 bandwidth per day.

Burning TRX — When bandwidth is insufficient, TRX is automatically burned at 1000 sun (0.001 TRX) per bandwidth unit. For a 345-bandwidth USDT transfer, that's about 0.345 TRX burned for bandwidth alone.

Resource Priority Order

Tron checks bandwidth availability in this order: delegated bandwidth → your staked bandwidth → free 600 daily bandwidth → TRX burn. The free allowance is consumed before any burning occurs, so casual users sending one or two transactions per day often pay nothing for bandwidth.

Frequently Asked Questions

How much bandwidth does a USDT transfer use?

A standard USDT (TRC-20) transfer consumes approximately 345 bandwidth units. This covers the transaction data size on the blockchain. Note that USDT transfers also require energy — bandwidth alone is not sufficient.

Is the 600 free daily bandwidth enough for USDT transfers?

Yes, 600 free bandwidth covers the bandwidth portion of one USDT transfer (345 units). However, you still need energy for the smart contract execution. The free bandwidth only eliminates the bandwidth cost — the energy cost remains.

Do I need to stake TRX separately for bandwidth and energy?

Yes. Tron's Stake 2.0 model lets you freeze TRX for either energy or bandwidth, but not both from the same stake. You choose which resource to receive when freezing.

How much does burning TRX for bandwidth cost?

Bandwidth burns at 1000 sun (0.001 TRX) per unit. A USDT transfer's 345 bandwidth costs about 0.345 TRX if burned. This is relatively minor compared to the energy cost of the same transfer.

Are simple TRX transfers free?

Effectively yes, for low-frequency users. A TRX transfer uses ~268 bandwidth and no energy. With 600 free bandwidth per day, you can send 2 TRX transfers daily at zero cost. Only high-frequency senders need to stake for additional bandwidth.
