Tunnel in 3 steps
-
Choose how much USDT to send and paste the Avalanche address that should receive funds on Avalanche C-Chain.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast USDT to that destination. Once confirmations clear, AVAX is pushed to your payout wallet.
Before you broadcast
- ERC-20 USDT follows Ethereum confirmation times.
- Send USDT on Ethereum mainnet only — not Tron TRC-20.
- Leave ETH in your wallet for gas when sending ERC-20 USDT.
- Still waiting on AVAX? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.
Tether — dollar-pegged stablecoin
USDT on Ethereum (ERC-20) is widely used in DeFi — send only on Ethereum mainnet.
USDT on Ethereum mainnet
Use an ERC-20 compatible Ethereum address. TRC-20 USDT is a different asset.
Avalanche — fast smart-contract L1
AVAX is the native token of Avalanche C-Chain — quick finality, EVM compatibility, and deep cross-chain liquidity.
AVAX not received?
Confirm your wallet is set to Avalanche C-Chain and fully synced.
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 for AVAX on TunnelSwap?
No. TunnelSwap is an anonymous no-KYC, privacy-first exchange. There is no account, no ID upload, and no standing balance for Tether → Avalanche swaps.
How fast is a USDT → AVAX swap?
Most routes settle within minutes. Final timing follows ERC-20 on Ethereum deposit confirmations and Avalanche C-Chain payout speed.
Does TunnelSwap hold my USDT or AVAX?
No. You fund the deposit from your wallet and AVAX is sent straight to the address you paste — non-custodial, wallet to wallet.
What if I use the wrong network for USDT?
Only send on the network shown for the order (ERC-20 on Ethereum). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
