Tunnel in 3 steps
-
Choose how much ADA to send and paste the Tether address that should receive funds on ERC-20 on Ethereum.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast ADA to that destination. Once confirmations clear, USDT is pushed to your payout wallet.
Before you broadcast
- Cardano deposits need several confirmations before the swap proceeds.
- Block times are around 20 seconds but can vary with network load.
- Use a Shelley-era Cardano address — legacy Byron formats may not be supported on all routes.
- 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.
Cardano — research-driven layer-1
ADA is the native token of Cardano — a proof-of-stake network focused on security and formal verification.
Sending ADA
Send native ADA on Cardano mainnet from a compatible wallet.
Leave enough ADA for the transaction fee in addition to your swap amount.
Tether — dollar-pegged stablecoin
USDT on Ethereum (ERC-20) is widely used in DeFi — send only on Ethereum mainnet.
Receiving ERC-20 USDT
Your wallet must be on Ethereum mainnet with the USDT token visible.

Frequently asked questions
Do I need KYC to swap ADA for USDT on TunnelSwap?
No. TunnelSwap is an anonymous no-KYC, privacy-first exchange. There is no account, no ID upload, and no standing balance for Cardano → Tether swaps.
How fast is a ADA → USDT swap?
Most routes settle within minutes. Final timing follows Cardano mainnet deposit confirmations and ERC-20 on Ethereum payout speed.
Does TunnelSwap hold my ADA or USDT?
No. You fund the deposit from your wallet and USDT is sent straight to the address you paste — non-custodial, wallet to wallet.
What if I use the wrong network for ADA?
Only send on the network shown for the order (Cardano mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
