Tunnel in 3 steps
-
Choose how much ETH 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 ETH to that destination. Once confirmations clear, AVAX is pushed to your payout wallet.
Before you broadcast
- Ethereum deposits confirm quickly — usually within a few blocks (~12s each).
- During gas spikes, confirmation cost rises but inclusion remains fast.
- Send ETH on Ethereum mainnet only — not BSC, Base, or other L2s unless your order says otherwise.
- 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.
Ethereum — programmable money on-chain
ETH powers Ethereum mainnet — gas, staking, DeFi, and most smart-contract activity in crypto live here.
Sending ETH to the right network
Use an Ethereum mainnet wallet for deposits. L2 or alternate-chain sends may not be credited.
Leave enough ETH in your wallet to cover gas on top of the swap amount.
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 ETH 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 Ethereum → Avalanche swaps.
How fast is a ETH → AVAX swap?
Most routes settle within minutes. Final timing follows Ethereum mainnet deposit confirmations and Avalanche C-Chain payout speed.
Does TunnelSwap hold my ETH 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 ETH?
Only send on the network shown for the order (Ethereum mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
