Tunnel in 3 steps
-
Choose how much BCH 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 BCH to that destination. Once confirmations clear, ETH is pushed to your payout wallet.
Before you broadcast
- Deposits on Bitcoin Cash mainnet follow that chain's confirmation times.
- Network congestion can occasionally delay inclusion — check status if stuck.
- Send only BCH on Bitcoin Cash mainnet to the address on your order page.
- 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.
Bitcoin Cash
Always match BCH on Bitcoin Cash mainnet when you send or receive — wrong-network transfers may not be credited.
Before you send
Use a wallet that supports Bitcoin Cash mainnet.
Verify the deposit network on your order page matches your wallet.
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 BCH 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 Bitcoin Cash → Ethereum (Base) swaps.
How fast is a BCH → ETH swap?
Most routes settle within minutes. Final timing follows Bitcoin Cash mainnet deposit confirmations and Base mainnet payout speed.
Does TunnelSwap hold my BCH 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 BCH?
Only send on the network shown for the order (Bitcoin Cash mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
