Tunnel in 3 steps
-
Choose how much ETH to send and paste the Decred address that should receive funds on Decred mainnet.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast ETH to that destination. Once confirmations clear, DCR is pushed to your payout wallet.
Before you broadcast
- Base confirmations are usually fast — often within a minute.
- Send ETH on Base mainnet only — not Ethereum L1, Optimism, or Arbitrum unless your order says otherwise.
- Use a Base-compatible wallet and address (0x…). Leave enough ETH on Base for gas on top of the swap amount.
- Still waiting on DCR? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.
ETH on Base — Coinbase L2
Native ETH on Base — Ethereum's value on Coinbase's L2 with low fees, fast finality, and growing on-chain activity.
ETH on Base mainnet
Use a Base wallet for deposits. Ethereum mainnet ETH is a different network — wrong-chain sends may not be credited.
Leave enough ETH on Base for gas in addition to the amount you swap.
Decred
Always match DCR on Decred mainnet when you send or receive — wrong-network transfers may not be credited.
Receiving DCR
Your wallet must be on Decred mainnet.
Allow a few minutes after the order shows sent before opening support.

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