Tunnel in 3 steps
-
Choose how much DCR to send and paste the Brett address that should receive funds on ERC-20 on Base.
-
Open the order to freeze the quote and reveal a one-time deposit destination.
-
Broadcast DCR to that destination. Once confirmations clear, BRETT is pushed to your payout wallet.
Before you broadcast
- Deposits on Decred mainnet follow that chain's confirmation times.
- Network congestion can occasionally delay inclusion — check status if stuck.
- Send only DCR on Decred mainnet to the address on your order page.
- Still waiting on BRETT? Give the wallet a few minutes to sync, then share your Exchange ID with support if the order already lists a payout hash.
Decred
Always match DCR on Decred mainnet when you send or receive — wrong-network transfers may not be credited.
Before you send
Use a wallet that supports Decred mainnet.
Verify the deposit network on your order page matches your wallet.
Brett on Base
Always match BRETT on ERC-20 on Base when you send or receive — wrong-network transfers may not be credited.
Receiving BRETT
Your wallet must be on ERC-20 on Base.
Allow a few minutes after the order shows sent before opening support.

What if I use the wrong network for DCR?
Only send on the network shown for the order (Decred mainnet). Wrong-chain deposits can be unrecoverable — review the safety guides before you broadcast.
