Why did my TRC20 fee double?

Usually because the address you sent to had never held USDT, which takes roughly twice the energy, or because your account ran out of energy and the network burned TRX instead. Staking or renting energy, or sending from an exchange, changes the cost.

Is BEP20 cheaper than TRC20?

Often, when you send from your own wallet without TRON energy: BNB Smart Chain fees are usually small. With enough energy, a TRC20 transfer can cost little TRX or none. From an exchange, compare the two withdrawal fees in its menu, since that's what you pay.

Which network is cheapest to receive on?

Receiving costs you nothing on any of them: the sender pays. What matters is the fee to move it on later, so pick a network whose gas coin you have, or receive into an exchange account.

Which USDT network is cheapest to send on?

By the Flipperr team · Last updated: 7 November 2026

No answer stays true for long: each network prices a transfer its own way, and the prices move. What does stay true is how each one works out the fee, and where to read today's number yourself. That's what this guide covers, with no fee figures that would be out of date next month.

The short answer

As a ranking that has held for a while, not a promise:

Ethereum mainnet has historically been the most expensive of the six to send USDT on, and its fee swings the most with demand.
BNB Smart Chain, Polygon, Arbitrum One and Solana are usually cheap.
TRON depends on your account. With energy from staked or rented TRX, a transfer costs little TRX or none. Without it, the network burns TRX to cover the transfer, and that's noticeably dearer.

Two things change the answer more than the network does: whether you send from your own wallet or from an exchange, and which networks the receiver accepts. Both are covered below.

How each network prices a USDT transfer

TRON (TRC20). A USDT transfer runs the USDT contract, which uses energy, and takes up some bandwidth. Your account pays with the energy and bandwidth it has, from staking TRX or renting energy, and the network burns TRX for whatever is missing. Sending to an address that has never held USDT uses roughly twice the energy of sending to one that has, because the contract has to create a balance for it. More on energy and bandwidth.

BNB Smart Chain, Ethereum, Polygon and Arbitrum One. The fee is the gas the transfer uses times the gas price, paid in BNB, ETH, POL, or ETH on Arbitrum One. A USDT transfer uses about the same amount of gas every time; the gas price is what moves, with how busy the network is. On Arbitrum, the fee also covers a share of the cost of posting its data to Ethereum.

Solana. Each transaction pays a small base fee, plus an optional priority fee that wallets add when the network is busy, all in SOL. If the recipient has never held USDT, the sender also funds a token account for them, a deposit Solana calls rent. How token accounts work.

How to check today's fee yourself

Your wallet's preview. Before you confirm a send, the wallet shows the estimated network fee in the gas coin. It's the most useful number, because it's for your transfer to your recipient.
TRON: on Tronscan, your account page shows the energy and bandwidth you have. If it's less than a USDT transfer needs, TRX is burned for the rest, and the wallet preview shows how much.
Ethereum: Etherscan's gas tracker shows current gas prices. BscScan and Polygonscan have gas tracker pages of their own for BNB Smart Chain and Polygon.
Arbitrum One and Solana: fees are usually small, and the wallet preview is the practical check.

Is there a TRC20 fee calculator?

Not an official one, but the sum is simple. A TRC20 transfer needs a certain amount of energy (more for a recipient with no USDT) and a little bandwidth. Whatever your account doesn't cover is paid by burning TRX, at a price per unit set by TRON's governance and listed among Tronscan's chain parameters. Most wallets do this sum and show the result before you confirm. Third-party calculators exist; treat them as estimates and trust the wallet preview.

From an exchange, the fee is the exchange's

When you withdraw from an exchange, you don't pay the network fee directly. The exchange pays it and charges you a withdrawal fee, set per network, which can be higher or lower than the network fee itself. So the cheapest network to withdraw on is the one with the lowest withdrawal fee in your exchange's menu, among the networks the receiver accepts. Exchanges change these fees, so check each time.

Some exchanges take the withdrawal fee out of the amount you type, so less arrives. If the receiver is a Flipperr deposit address, a short deposit can put the swap on hold until support sorts it out, so add the fee on top.

Comparing routes on Flipperr

When Flipperr sends to you, the network fee for that payout is already inside the “You get” amount, along with Flipperr's fee. To compare networks for a swap, set the form to each route you'd accept and compare that number. The fee for sending your deposit is separate: it's whatever your wallet or exchange charges.

The cheapest network is no use if the receiver doesn't list it: a deposit on a network it doesn't accept may never be credited. Check the receiver first, then compare fees among the networks it takes. Which network to use.
