Tunnel in 3 steps
-
Choose how much BTC to send and paste the Tether address that should receive funds on TRC-20 on Tron.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast BTC to that destination. Once confirmations clear, USDT is pushed to your payout wallet.
Before you broadcast
- One on-chain confirmation is usually enough before your payout leg starts.
- BTC confirmation time depends on mempool congestion and the fee you paid.
- SegWit deposit addresses keep fees lower. If your wallet cannot send to SegWit, contact support before sending.
- Still waiting on USDT? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists 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.
Tether — dollar-pegged stablecoin
USDT tracks the US dollar and is widely used for trading and transfers — always match the correct chain (TRC-20, ERC-20, etc.).
Receiving USDT on the correct chain
Your wallet must support the exact USDT network listed on the order.
If funds were sent on the wrong chain, recovery may not be possible — verify before you send.
When will USDT arrive?
Most TRC-20 payouts land within minutes once your deposit confirms.
- Check the order page for a payout transaction hash before opening a support ticket.
- Refresh or resync your wallet if the balance has not updated after a few minutes.
- Tron confirmations are typically much faster than Bitcoin or Ethereum mainnet.
Why traders swap into USDT
USDT offers dollar-like stability without leaving crypto — useful between trades or during volatile markets.
TRC-20 USDT on Tron keeps transfer fees low, making it a common destination after swapping from BTC, ETH, or alt L1s.

Only send on the network shown for the order (Bitcoin mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
