Tunnel in 3 steps
-
Enter the BTC amount and paste the Ethereum mainnet address that should receive ETH.
-
Create the swap order to lock pricing and reveal a one-time BTC deposit address.
-
Send BTC from your wallet. After Bitcoin confirms, ETH is delivered to your payout address.
Before you broadcast
- A single Bitcoin confirmation is usually enough before TunnelSwap starts the ETH payout leg.
- BTC speed tracks mempool load and the fee you choose — quiet periods confirm faster than fee wars.
- SegWit (bc1…) deposits typically cost less and confirm sooner. Legacy-only wallets should check with support before sending.
- ETH still missing? Wait for wallet sync, then contact support with your Exchange ID if the order already shows a payout hash.
Bitcoin — the original digital asset
Since 2009, Bitcoin has been the benchmark cryptocurrency — deep liquidity, wide recognition, and the default on-ramp for cross-chain swaps.
Before you send BTC
- Confirm your wallet can send to SegWit (bc1…) addresses.
- Leave enough for a network fee — low fees mean slower confirmation.
- Send only BTC on Bitcoin mainnet to the address on your order page.
How long until Bitcoin confirms?
Block times vary with network load and your chosen fee.
- Use mempool.space or similar tools to check whether your fee is competitive.
- Explorers show queue position — compare against pending transaction volume.
- Average block interval is ~10 minutes, but longer gaps happen.
Why traders move BTC to other chains
Bitcoin offers deep liquidity and wide recognition — many swaps start with BTC as the funding asset.
Moving into Ethereum, stablecoins, or alt L1s lets you access DeFi, payments, or portfolio diversification without a custodial account.
Ethereum — programmable money on-chain
ETH powers Ethereum mainnet — gas, staking, DeFi, and most smart-contract activity in crypto live here.
What if my ETH hasn't arrived?
Check the order page for a payout transaction hash first.
Confirm your wallet is on Ethereum mainnet and fully synced.
How fast is the ETH payout?
Most payouts land within minutes once your deposit confirms — Ethereum blocks are ~12 seconds apart.
Receiving ETH on the correct network
- Payouts go to Ethereum mainnet — not BSC, Base, Arbitrum, or other L2s unless your order explicitly lists them.
- Double-check the address you paste: one wrong character sends funds to an unreachable wallet.
- Self-custody wallets (MetaMask, Rabby, hardware devices) are recommended for long-term holding.
Float vs fixed rate on ETH payouts
The rate mode you pick at the top of the swap widget affects how your final ETH amount is calculated.
- Float rate follows the market until your deposit confirms — best when mempools are quiet.
- Fixed rate locks the quote for a short window — useful when ETH price is moving quickly.

Frequently asked questions
Do I need KYC to swap BTC 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 → Ethereum swaps.
How fast is a BTC → ETH swap?
Most routes settle within minutes. Final timing follows Bitcoin mainnet deposit confirmations and Ethereum mainnet payout speed.
Does TunnelSwap hold my BTC 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 BTC?
Only send on the network shown for the order (Bitcoin mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
