Tunnel in 3 steps
-
Choose how much BNB to send and paste the Bitcoin address that should receive funds on Bitcoin mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast BNB to that destination. Once confirmations clear, BTC 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 BTC? 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.
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.
When is my BTC spendable?
After your payout transaction receives the confirmations shown on the order page — typically one or more blocks depending on route.
Checking your BTC payout
- Open the order page and copy the payout transaction hash into a Bitcoin block explorer.
- Confirm the destination address matches your wallet exactly — including case and format.
- Most wallets show incoming BTC after one confirmation; some exchanges wait for more.

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