Tunnel in 3 steps
-
Choose how much AVAX to send and paste the Tether address that should receive funds on ERC-20 on Ethereum.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast AVAX to that destination. Once confirmations clear, USDT is pushed to your payout wallet.
Before you broadcast
- Avalanche C-Chain confirmations are typically very fast — often under a minute.
- Send AVAX on Avalanche C-Chain only — not X-Chain or P-Chain unless your order specifies them.
- Use a C-Chain compatible wallet and address (0x…). Leave enough AVAX for gas.
- Still waiting on USDT? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.
Avalanche — fast smart-contract L1
AVAX is the native token of Avalanche C-Chain — quick finality, EVM compatibility, and deep cross-chain liquidity.
AVAX on Avalanche C-Chain
Use an Avalanche C-Chain wallet for deposits. X-Chain and P-Chain addresses are not interchangeable with C-Chain.
Leave enough AVAX in your wallet to cover gas on top of the swap amount.
Tether — dollar-pegged stablecoin
USDT on Ethereum (ERC-20) is widely used in DeFi — send only on Ethereum mainnet.
Receiving ERC-20 USDT
Your wallet must be on Ethereum mainnet with the USDT token visible.

Frequently asked questions
Do I need KYC to swap AVAX for USDT on TunnelSwap?
No. TunnelSwap is an anonymous no-KYC, privacy-first exchange. There is no account, no ID upload, and no standing balance for Avalanche → Tether swaps.
How fast is a AVAX → USDT swap?
Most routes settle within minutes. Final timing follows Avalanche C-Chain deposit confirmations and ERC-20 on Ethereum payout speed.
Does TunnelSwap hold my AVAX or USDT?
No. You fund the deposit from your wallet and USDT is sent straight to the address you paste — non-custodial, wallet to wallet.
What if I use the wrong network for AVAX?
Only send on the network shown for the order (Avalanche C-Chain). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
