Exchange in 3 steps
-
Choose how much USDT to send and enter your Avalanche address on Avalanche C-Chain.
-
Hit Exchange to open your order page with the live rate and deposit details.
-
Transfer USDT to the address on your order — after confirmations, AVAX is sent to your wallet automatically.
What do you need to know?
- Deposits on ERC-20 on Optimism follow that chain's confirmation times.
- Send only on ERC-20 on Optimism — other networks are not interchangeable.
- Double-check the network on your order page before you send.
- AVAX not visible yet? Wait a few minutes, resync your wallet, then contact support with your order ID if the payout tx is already listed.
Tether on Optimism

Before you send
Use a wallet that supports ERC-20 on Optimism.
Verify the deposit network on your order page matches your wallet.

AVAX payout tips
- Payouts go to Avalanche C-Chain — use a 0x-style address compatible with your wallet.
- Check Snowtrace or a similar explorer with the payout tx hash from your order page.
- Allow a minute for your wallet to refresh after the explorer shows the transfer.

Frequently asked questions
Do I need KYC to swap USDT to AVAX?
No. SendSwap is a non-custodial instant exchange — no account, no ID checks, and no KYC for Tether to Avalanche swaps.
How long does USDT to AVAX take?
Most swaps finish in 1–5 minutes. Timing depends on ERC-20 on Optimism and Avalanche C-Chain confirmations and current network load.
Is USDT to AVAX non-custodial?
Yes. You send USDT from your wallet and receive AVAX directly to the address you provide — SendSwap never holds your keys.
What if I send USDT on the wrong network?
Always match the network on your order page (ERC-20 on Optimism for deposits). Wrong-network sends may not be credited — read our swap safety guides before you send.
