Compare Cross-Chain Swaps by the Amount You Receive
Compare routes by the amount expected to arrive after swap fees, bridge costs and slippage; quotes can change before execution, so check destination details too.

Compare cross-chain swap routes by the amount of the destination token expected to reach your wallet after fees and slippage. A headline exchange rate leaves out costs and execution differences that can change the result. For a fuller explanation of how the route works, see bungee bridge.
What does the final amount include?
The final amount is the estimated destination-token balance after the route’s swaps and bridge costs. Depending on the route, costs can include a source-chain transaction fee, a bridge fee, a destination swap fee and gas needed to complete the destination transaction.
Some costs are charged in a different token from the one being swapped. Check what leaves your wallet on the source chain as well as what the quote estimates will arrive on the destination chain; a large arrival amount is not the whole cost if extra funds are needed for gas.
How should you compare route quotes?
Compare quotes for the same source amount, source token, destination token and destination chain. Then compare the estimated amount received, making sure you are looking at the same unit and that any separate gas requirements are clear.
- Amount out: the estimated destination-token balance after the route completes.
- Wallet spend: the source amount plus any separate fees or gas the route requires.
- Route steps: the swaps and transfers involved, which can affect costs and execution.
- Quote conditions: the displayed slippage setting and how long the quote remains usable.
A route with more steps may still produce a higher estimated amount, while a better-looking quote may depend on conditions that change before execution. Use the estimated amount and full wallet spend together to judge the trade-off.
Why can the amount change before arrival?
The amount received can differ from the estimate because prices move while transactions are pending and swaps execute against available liquidity. Slippage settings define how much price movement a swap can tolerate before it fails or completes at a worse rate, depending on the route’s rules.
Bridge transfers also involve separate transactions across networks, so completion time and the destination balance may depend on each step finishing successfully. A quote is an estimate at the time it is shown, not a guaranteed final balance.
Which route is the better choice?
For most readers, the better route is the one with the strongest estimated amount after accounting for every required fee and the destination gas needed to use the tokens. A small difference in quoted output may not justify extra route complexity or a tighter execution window.
Before signing, verify the recipient address, destination network, token and amount, then review the transaction details in your wallet. Compare again if the quote expires or market conditions change; the next decision point is the quote shown immediately before you confirm the swap.
