Tunnel in 3 steps
-
Choose how much BNB to send and paste the Ethereum (Base) address that should receive funds on Base mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast BNB to that destination. Once confirmations clear, ETH is pushed to your payout wallet.
Before you broadcast
- BSC confirmations are usually fast — often within a minute.
- Send BNB on BNB Smart Chain only — not BEP2 or other networks unless your order specifies them.
- Leave enough BNB for gas when sending BEP-20 tokens from the same wallet.
- Still waiting on ETH? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.
BNB — native gas on BSC
BNB powers BNB Smart Chain — fast EVM transfers and the gas token for BEP-20 tokens on BSC.
BNB on BSC
Use a BSC-compatible wallet and address (0x…).
Do not send BNB on Ethereum or other chains — wrapped versions are different assets.
ETH on Base — Coinbase L2
Native ETH on Base — Ethereum's value on Coinbase's L2 with low fees, fast finality, and growing on-chain activity.
Base ETH not received?
Confirm your wallet is on Base mainnet and fully synced — not Ethereum L1.
Base ETH payout tips
- Payouts go to Base — verify your wallet network is Base (chain ID 8453).
- Check Basescan with the payout tx hash from your order page.
- Bridging to Ethereum L1 is a separate step after you receive ETH on Base.

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