Fees & slippage
Understand what you send, what you receive, and what can change.
Reading a quote#
Arc Bridge requests live market quotes from Relay for supported pairs. The sending amount is the quantity of the source token; the receiving amount and USD values come from the provider’s response. The app does not substitute fixed prices when a route is unavailable.
Expand the quote row for a full breakdown. Quotes refresh every 30 seconds while the page is active, and you can select Refresh quote at any time. Output amounts, fees, and estimated times can change. Transfer execution remains unavailable.
Bridge fee#
The bridge fee appears below the asset panels and again on the review screen. It is included in the estimated receiving amount. Check the fee after changing a network, token, or amount.
Slippage tolerance#
Open the settings button beside the direction tabs to choose 0.1%, 0.5%, or 1%. Changing this setting requests a new quote. The minimum received amount comes directly from Relay’s response and reflects its route and token precision.
Gas on Arc#
Arc charges network gas in USDC. Network gas and bridge fees are separate costs. Official Arc gas reference ↗.
