Before you start

  • Wallet connected for the chain you’re bridging from (Connect a wallet)
  • That wallet’s settlement key registered — the app blocks order creation until it is
  • Test funds (faucet)

​
1. Pick a route and amount

On the Bridge tab, choose source and destination, enter the amount, and set the destination address (defaults to your linked wallet on the other chain).

Set the amount — what you pay is what you get, 1:1

​
2. Create and fund the order

Confirm the deposit transaction in your wallet (ERC-20 routes ask for an approval first, so expect two prompts). Your tokens go into the OrderPortal — the escrow contract on your chain — where they stay locked until the trade settles or you get them back.

Order submitted confirmation

Order submitted — the maker's side takes over

Closed the popup by mistake? The order waits on the Orders page — Complete Order re-serves the same transaction without reserving more liquidity. Unfunded orders expire after ~30 minutes.

​
3. The maker locks

Once your deposit confirms, the maker locks the matching funds on the other chain (makers running the market-maker bot lock automatically). The trade shows Locked.

​
4. Co-sign

When both deposits are settlement-grade — confirmed deeply enough to settle against, usually under a minute — the Co-sign button lights up. One wallet signature unlocks your settlement key; the key signs the trade silently — no transaction, no gas.

Co-sign — instant, no gas

​
5. Done — the rest is automatic

Background workers aggregate the two signatures, generate the deposit proofs, and submit the unlocks on both chains:

Your bridged tokens arrive at the destination address. The trade page links both unlock transactions.
