Tunnel in 3 steps
-
Choose how much USDT to send and paste the Polygon address that should receive funds on Polygon mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast USDT to that destination. Once confirmations clear, MATIC is pushed to your payout wallet.
Before you broadcast
- TRC-20 USDT confirms quickly on Tron — usually within a minute or two.
- Never send USDT on the wrong network. TRC-20, ERC-20, and other variants are not interchangeable.
- Keep a small TRX balance in your wallet to pay Tron energy/bandwidth for TRC-20 sends.
- Still waiting on MATIC? 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 tracks the US dollar and is widely used for trading and transfers — always match the correct chain (TRC-20, ERC-20, etc.).
USDT network mismatch
The most common error is sending ERC-20 USDT to a TRC-20 address or vice versa.
Double-check the network badge on your order before sending.
Polygon — low-cost EVM layer-2
MATIC (POL) powers Polygon — fast EVM transfers, low fees, and wide DeFi and bridge liquidity.
MATIC not received?
Confirm your wallet is on Polygon PoS mainnet and fully synced.
MATIC payout tips
- Use a Polygon-compatible wallet and verify the receive address starts with 0x.
- Check Polygonscan with the payout tx hash if your balance has not updated.
- Do not expect MATIC on Ethereum — this route pays out on Polygon PoS.

Frequently asked questions
Do I need KYC to swap USDT for MATIC 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 → Polygon swaps.
How fast is a USDT → MATIC swap?
Most routes settle within minutes. Final timing follows TRC-20 on Tron deposit confirmations and Polygon mainnet payout speed.
Does TunnelSwap hold my USDT or MATIC?
No. You fund the deposit from your wallet and MATIC 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 (TRC-20 on Tron). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
