SWAPCROSS

Cross-chain token swaps across L1 and L2 networks.

SwapCross

Open Application

What It Is

Cross-chain swap interface. Select source chain, destination chain, input token, and output token. The application finds routes and executes the swap.

Non-custodial. Users sign transactions in their own wallet.

How It Works

Connect wallet
Select source chain and token
Select destination chain and token
Enter amount
Review quote (rate, fees, estimated time)
Confirm transaction in wallet
Receive tokens on destination chain

Execute transactions without user signature

All swaps require wallet approval.
