What is Bandwidth on TRON?

Bandwidth is the data-transfer resource consumed by every single transaction on TRON — even a simple TRX transfer. The good news? You get some for free every day.

The basics

Bandwidth explained in 60 seconds

Bandwidth (measured in Bandwidth Points, or BP) is consumed by every transaction on the TRON network — regardless of whether it touches a smart contract or not. The amount of Bandwidth needed is proportional to the byte size of the transaction data stored on-chain. A simple TRX transfer is ~267 bytes, so it costs ~267 BP.

Unlike Energy (which has no free allowance), every TRON account receives approximately 600 free Bandwidth Points per day. These regenerate automatically over 24 hours. For most casual users, this free allowance is enough to cover 1–2 simple transfers per day at zero cost.

When your free Bandwidth is exhausted and you have no staked Bandwidth, the network burns TRX from your wallet at 1,000 SUN per Bandwidth Point (= 0.001 TRX per BP). This is relatively cheap per transaction (~0.267 TRX for a TRX transfer), but adds up for high-volume users or complex transactions with large data payloads.

Bandwidth-only transactions

Transactions that consume only Bandwidth (no Energy)

These operations do not interact with any smart contract, so they need zero Energy. They only consume Bandwidth proportional to transaction size. If you have free BP available, they cost literally zero TRX.

Transaction Type	Typical BP	With Free BP	TRX burned (no BP)
TRX Transfer	~267	Free	~0.267 TRX
TRX Transfer (with memo)	350–500	Free	0.35–0.50 TRX
TRC-10 Token Transfer	~300	Free	~0.300 TRX
Stake TRX (v2)	~275	Free	~0.275 TRX
Unstake TRX (v2)	~275	Free	~0.275 TRX
Delegate Resource	~300	Free	~0.300 TRX
Vote for SRs	300–500	Free	0.30–0.50 TRX
Claim Voting Rewards	~250	Free	~0.250 TRX
New Account Activation	~267 + 1 TRX	1 TRX only	~1.267 TRX

Smart contract transactions (USDT, SunSwap, JustLend…) consume both Bandwidth and Energy. The Bandwidth component is typically 300–500 BP (negligible cost), while Energy is where the real expense lies. See the Energy guide for full details.

Three ways to get Bandwidth beyond the free allowance

🎁

1. Free daily allowance

Every TRON account automatically receives ~600 BP/day. This covers 1–2 simple transfers. If you only send TRX or TRC-10 tokens occasionally, the free allowance may be all you need — and you'll never pay a cent.

🔐

2. Stake TRX for Bandwidth

Freeze TRX via Stake 2.0 and select "Bandwidth" as the resource. Your staked BP regenerates over 24h. Best for high-volume senders or exchanges processing many TRX/TRC-10 transfers daily.

📡

3. Rent Bandwidth

Some energy pools also offer Bandwidth rentals. This is useful for bursts of high activity (batch transfers, airdrops). Check our Buy section for current Bandwidth prices.

Comparison

Bandwidth vs Energy — what's the difference?

Feature	Bandwidth (BP)	Energy
Consumed by	Every transaction (proportional to byte size)	Smart contract transactions only
Free daily allowance	~600 BP/day	0 (none)
Burn rate when missing	1,000 SUN per BP	100 SUN per unit
DEM multiplier applies?	No	Yes (up to 3.4× on popular contracts)
Typical cost per USDT transfer	~345 BP (usually free)	65,000–131,000 units (expensive without)
Regeneration	24h linear (staked BP)	24h linear (staked Energy)
Where to rent	Some pools offer BW	All major pools

In practice: Bandwidth is rarely the bottleneck. The free 600 BP/day covers most casual users, and even when burned, the cost is minimal (~0.27 TRX per transfer). Energy is where the real savings opportunity lies — a single USDT transfer without Energy burns 6.5 TRX. That's why renting Energy is the #1 cost optimization for TRON users.

FAQ

Frequently asked questions about TRON Bandwidth

Is 600 free BP/day enough for normal use?

For most casual users, yes. A single TRX transfer uses ~267 BP, so you can do 2 free transfers per day. If you also send TRC-20 tokens like USDT, the Bandwidth component (~345 BP) is also covered by the free allowance — but you'll still need Energy for the smart contract part.

What happens when free Bandwidth runs out?

TRON checks your staked Bandwidth next. If that's also depleted, the network burns TRX at 1,000 SUN per BP. For a ~267 BP transfer, that's only ~0.267 TRX — relatively cheap, but it adds up with heavy use.

Should I stake TRX for Bandwidth or Energy?

Almost always Energy. Bandwidth is cheap (0.001 TRX per BP) and you get 600 free per day. Energy has no free allowance and costs 0.0001 TRX per unit — but operations need 65,000+ units, making it far more expensive. Stake for Energy, and let the free allowance handle Bandwidth.

Do smart contract transactions use Bandwidth too?

Yes. Every transaction uses Bandwidth (for the raw transaction data). Smart contract calls use both Bandwidth (~300–500 BP, usually covered by free allowance) and Energy (the expensive part). The Energy is what you need to rent or stake for — Bandwidth is essentially free for most users.

How does Bandwidth regeneration work?

Free Bandwidth and staked Bandwidth both regenerate linearly over 24 hours. If you use all 600 free BP at 8am, you'll have ~300 BP back by 8pm and the full 600 by 8am the next day. Staked BP follows the same 24h cycle.

Can I rent Bandwidth?

Yes. Several energy pools also offer Bandwidth rentals, though it's far less common than Energy. Check the Buy section — filter by "Bandwidth" to see current offers and prices.

Bandwidth is free — but Energy isn't

The real cost saver on TRON is renting Energy. Compare all pool prices and cut your smart contract fees by 60%.

TRON Bandwidth: the complete guide to transaction data costs on the TRON blockchain

Bandwidth Points (BP) are consumed by every transaction on the TRON network, proportional to the byte size of the on-chain data. Every account receives approximately 600 free BP per day, making simple TRX and TRC-10 transfers effectively free for casual users. When free Bandwidth is exhausted, TRX is burned at 1,000 SUN per BP — a rate that's relatively affordable but adds up for high-volume operations. For users who send hundreds of transactions daily, staking TRX specifically for Bandwidth eliminates this cost entirely.

While Bandwidth is rarely the primary concern for TRON users, understanding how it interacts with Energy is key to optimizing total transaction costs. Smart contract calls (USDT transfers, DeFi swaps, token operations) consume both resources — and it's the Energy component that represents 95%+ of the cost. TronScan.energy helps users minimize both by comparing rental prices across all major TRON energy and bandwidth pools.
