Cheapest network for sending USDT

Direct answer

On the published South African fee tables, the cheapest networks for sending USDT are the ones AltCoinTrader prices at 2 USDT per withdrawal: Arbitrum, Avalanche, NEAR, Optimism, Solana and TON. Tron (TRC20) costs 5 USDT there, BNB Smart Chain was showing a dynamic fee of about 4.24 USDT, and Ethereum (ERC20) about 8.56 USDT. Ovex charges 8.0 USDT to send USDT on Ethereum. Luno, VALR and Binance do not publish a per-network table; they show a dynamic, network-based fee on the withdrawal screen. The cheapest network is only cheap if the receiving wallet or exchange supports it, so check the destination first and the fee second.

Fees were read on the platforms’ official pages on 6 September 2026 and change with network conditions.

Who this guide is for

South Africans moving USDT from a local exchange to a wallet, to another exchange, or to someone else, who want to avoid paying a large fixed fee on a small transfer. It assumes you already hold USDT; our guide to buying USDT in South Africa covers the purchase.

Why the network matters

USDT is issued on many blockchains, and a USDT balance on one network is a different token from a USDT balance on another. When you withdraw, the exchange asks which network to use and charges a fee that reflects that network’s transaction cost plus, at some platforms, a margin. The receiving side must support the same network, or the transfer is lost. Some networks also require a memo or tag in addition to the address; omitting it can mean the deposit is never credited. Nothing about the fee tells you whether the destination supports the network, which is why the destination check comes first.

Published fees by network

AltCoinTrader

AltCoinTrader’s fee page lists crypto deposits as free for every asset and a fixed withdrawal fee per asset and network, with some networks marked dynamic. For USDT, when read on 6 September 2026:

• Arbitrum, Avalanche, NEAR, Optimism, Solana, TON: 2 USDT each.
• Tron (TRC20): 5 USDT.
• BNB Smart Chain: about 4.24 USDT (dynamic).
• Ethereum (ERC20): about 8.56 USDT (dynamic).

Ovex

Ovex publishes a flat withdrawal fee per asset regardless of amount. Its fee table lists USDT on Ethereum at 8.0 USDT and USDC on Ethereum at 8.0 USDC, alongside 0.00015 BTC for bitcoin and 0.0025 ETH for ether. Other USDT networks were not shown in the table we read.

Luno, VALR and Binance

Luno charges a dynamic send fee that combines the live blockchain fee with its operational costs, shown before you confirm; XRP is the only fixed fee at 0.03 %. VALR quotes a network-dependent fee on the withdrawal screen, states that it can be more than it pays the network, and sets the minimum withdrawal at roughly three times the fee. Binance says its withdrawal fees are dynamic and automatically adjusted to network conditions and are paid to the network. For these three platforms the only reliable number is the one on your screen at the moment of withdrawal.

Worked examples (assumptions, not quotes)

Assume you send 100 USDT and pay the published fee from the same balance:

• AltCoinTrader on Solana or Arbitrum: 2 USDT, so 2 % of the transfer.
• AltCoinTrader on Tron: 5 USDT, 5 %.
• AltCoinTrader on Ethereum: about 8.56 USDT, about 8.6 %.
• Ovex on Ethereum: 8.0 USDT, 8 %.

Send 2,000 USDT instead and the same fees fall to 0.1 %, 0.25 %, about 0.43 % and 0.4 %. Fixed fees punish small transfers, so batching several small sends into one is the single biggest saving on any network.

Checks before you choose a network

1. Does the destination support it? Open the receiving wallet or exchange’s deposit screen for USDT and read the list of networks it accepts. If your chosen network is not listed, do not send.
2. Is a memo or tag required? Some networks and some exchanges require one; copy it exactly.
3. Is the address for that network? Addresses are network-specific; an address copied from the wrong network’s deposit screen will not receive the funds.
4. What is the minimum? VALR’s minimum is generally three times the fee, and every platform sets its own.
5. Send a small test first when the amount is large; the extra fee is cheaper than an irreversible mistake.
6. Check the issuer’s own documentation for which networks USDT officially exists on; exchanges add and remove networks over time.

Availability limitations

Luno caps sends by verification level at USD 2,400 per 24 hours (Level 1), USD 12,000 (Level 2) and USD 120,000 (Level 3). AltCoinTrader gates withdrawals by FICA level (R100 once-off at Level 1, R200,000 per 24 hours at Level 2, R1,000,000 at Level 3). Ovex requires full verification before any withdrawal. Whether a specific network is available to you on a given day depends on the platform, which may pause a network for maintenance.

Risks

A transfer on the wrong network or to an address without its required memo is usually unrecoverable, and no platform we read promises to retrieve it. Dynamic fees can change between the moment you read this page and the moment you confirm. USDT itself is issued by a private company and can trade away from one dollar; sending it does not change that. Fees here were verified on 6 September 2026.
