Tunnel in 3 steps
-
Choose how much ETH to send and paste the Polygon address that should receive funds on Polygon mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast ETH to that destination. Once confirmations clear, MATIC 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 MATIC? 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.
Polygon — low-cost EVM layer-2
MATIC (POL) powers Polygon — fast EVM transfers, low fees, and wide DeFi and bridge liquidity.
MATIC not received?
Confirm your wallet is on Polygon PoS mainnet and fully synced.
MATIC payout tips
- Use a Polygon-compatible wallet and verify the receive address starts with 0x.
- Check Polygonscan with the payout tx hash if your balance has not updated.
- Do not expect MATIC on Ethereum — this route pays out on Polygon PoS.

Frequently asked questions
Do I need KYC to swap ETH for MATIC 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 → Polygon swaps.
How fast is a ETH → MATIC swap?
Most routes settle within minutes. Final timing follows Ethereum mainnet deposit confirmations and Polygon mainnet payout speed.
Does TunnelSwap hold my ETH or MATIC?
No. You fund the deposit from your wallet and MATIC 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.
