Tunnel in 3 steps
-
Choose how much USDT 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 USDT to that destination. Once confirmations clear, BTC is pushed to your payout wallet.
Before you broadcast
- ERC-20 USDT follows Ethereum confirmation times.
- Send USDT on Ethereum mainnet only — not Tron TRC-20.
- Leave ETH in your wallet for gas when sending ERC-20 USDT.
- 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.
Tether — dollar-pegged stablecoin
USDT on Ethereum (ERC-20) is widely used in DeFi — send only on Ethereum mainnet.
USDT on Ethereum mainnet
Use an ERC-20 compatible Ethereum address. TRC-20 USDT is a different asset.
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 USDT 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 Tether → Bitcoin swaps.
How fast is a USDT → BTC swap?
Most routes settle within minutes. Final timing follows ERC-20 on Ethereum deposit confirmations and Bitcoin mainnet payout speed.
Does TunnelSwap hold my USDT 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 USDT?
Only send on the network shown for the order (ERC-20 on Ethereum). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
