Which USDT network is cheapest?

Tron or Solana USDT usually beat Ethereum for transfer cost. The Swap.bz service fee is still 0.5% Standard or 1% Private on any of them. Pick the network your destination actually supports.

Can I swap TRC-20 USDT to BTC?

Yes when Tron is selected in the widget and you send TRC-20 to the shown deposit. Receive must be a Bitcoin address.

I sent ERC-20 to a Tron quote. Now what?

Cross-network USDT is often unrecoverable. Contact Support with the txid — do not send a second deposit to “fix” it.

USDT TRC-20 vs ERC-20

Same ticker. Two ledgers. The quote names one of them — your wallet must send on that one.

TRC-20 USDT lives on Tron (addresses start with T). ERC-20 USDT lives on Ethereum (0x). Sending Tron USDT to an Ethereum deposit — or the reverse — is one of the most common ways to lose a Tether transfer. Swap.bz cannot treat them as interchangeable.

Tron is usually cheaper and faster. Ethereum pays L1 gas, which can dwarf the 0.5% service fee on small sizes. Solana USDT is a third option when the widget lists it. Always read the network label next to USDT, not the icon.

If you withdraw USDT from an exchange, that withdrawal screen also names a network. It must match the Swap.bz send network exactly.

What to do

1.In the wallet or exchange, note whether the USDT is Tron, Ethereum, or Solana.
2.On Swap.bz, select that same USDT network on the send side.
3.Send only that USDT to the deposit address shown — no USDC, no native TRX/ETH as a substitute.
4.If you already sent the wrong network, keep the txid and order ID for Support. Recovery is not guaranteed.

Before you send

A T-address will not collect ERC-20 USDT. An 0x deposit will not collect TRC-20.

USDT and USDC are different tokens on every chain.

Use the address checker for format, then still match the quote network.
