Source-chain gas
The source network charges gas to approve or send the deposit. Gas is paid in that network’s native gas token and changes with network demand.
Bridge Fees Explained
Understand source gas, provider fees, liquidity costs, slippage, quote movement, and the final receive amount on a bridge route.
What you need to know
Destination-chain gas
Some routes include destination execution costs or require the receiving wallet to hold the destination gas token for later activity. The quote should state what is included.
Provider and bridge fees
A route provider can charge an execution or bridge fee. Sasquatch displays provider information from the current quote; it does not promise a fixed fee outside that quote.
Liquidity costs and slippage
Routes that exchange assets depend on available liquidity. Slippage and price impact can change the output, especially for larger amounts or thinner markets.
Why quotes move
Network gas, asset prices, liquidity, provider availability, confirmation requirements, and route capacity can all change between quotes.
Amount size and route selection
A route that works well for a small amount may not provide the best output for a larger amount. Compare the final estimated receive amount, not only a single fee line.
Cheapest fee versus best output
The lowest displayed fee can still produce a worse final result if its exchange rate, price impact, liquidity cost, or destination output is less favorable.
How to compare routes
Compare the exact source amount, destination asset and network, total estimated receive amount, minimum received, gas requirements, provider costs, and estimated timing immediately before creating the order.

Bridge Fees Explained FAQs
Why did the bridge quote change?
Gas, prices, liquidity, route capacity, and provider availability can change. Refresh the quote before depositing.
Is source-chain gas included?
It depends on the route and wallet transaction. Treat wallet-displayed source gas separately unless the quote explicitly says it is included.
Does the lowest fee always give the best output?
No. Compare the final receive amount and minimum received because rate and liquidity differences can outweigh a lower fee.
Can a larger bridge amount cost more?
Yes. Larger amounts can encounter different liquidity, price impact, provider limits, or route selection.
