Exchange

How it works

XyloNet does not run its own AMM on mainnet. When you request an exchange, the card asks LI.FI for a route across the DEXs and bridges it aggregates, shows you the expected output, fees and time, and then executes that route through the LI.FI Diamond contract. Same-chain swaps on Arc and cross-chain swaps (for example ETH on Base to USDC on Arc) use the same flow.

1. 1
   Quote

   Pick source and destination tokens (and chains) and an amount. LI.FI returns one or more routes.
2. 2
   Approve

   If the source token is an ERC-20, approve the LI.FI Diamond (or Permit2) for the amount.
3. 3
   Execute

   Sign one transaction. Single-chain swaps complete in the same block on Arc; cross-chain routes complete once the bridge leg settles.
4. 4
   Receive

   Tokens land in the receiving address you chose, by default your connected wallet.

Fees

• DEX and bridge fees are set by the venues in the route and are shown in the quote.
• XyloNet is registered with LI.FI as integrator xylonet. An integrator fee of 0.10% is added to routes that start on Arc and displayed before you sign. Any integrator fee is collected by the LI.FI FeeForwarder and routed to the XyloNet Treasury Safe.
• Gas on Arc is paid in USDC and typically costs a fraction of a cent.

Slippage and safety

• The quote includes a minimum received amount. If the market moves beyond your slippage tolerance the transaction reverts.
• Verify the destination token address in the quote; LI.FI lists tokens by symbol and address.
• Approvals are granted to the LI.FI Diamond at the address below. Revoke them any time from your wallet.
