Rabby Swap retrieves quotes from aggregators inside the wallet. Its current guide lists a 0.25% service fee already included in the quote, while a separate, newer page documents eligible pairs with the Rabby fee waived. Use both pages when evaluating a trade.
The swap guide describes selecting the network, input token and output token on Extension or Mobile. On Mobile, the address at the top is the default trading account. Check it before comparing balances or signing; an account selection mistake can look like a missing-liquidity problem.
Which swaps receive the exemption?
The July 21, 2026 exemption list groups eligible stablecoins and ETH-related assets. Both tokens must belong to the same listed group and the same chain. Its BNB stablecoin list includes USDT, USDC, FDUSD, DAI and USDe, identified by contract address. This is an exemption from Rabby’s service fee, not a statement that network or execution costs disappear.
For an eligible BNB pair, compare the net receive amount with another BNB quote. Do not subtract 0.25% again from a quote that already incorporates its actual fee treatment.
Support and approval boundaries
Rabby distinguishes an unavailable quote from a chain unsupported by its aggregator. The ability to hold an asset in the wallet does not establish that the built-in swap can trade it. An external dApp may provide another route, but it requires its own evaluation.
The guide says the built-in Approve and Swap flow approves the required swap amount. Do not extend that statement to every external dApp opened with Rabby: inspect the permission each application actually requests.
A high-impact warning is another decision point, not a prompt to increase slippage mechanically. Rabby explicitly explains that changing slippage does not repair a quote made unattractive by shallow liquidity. The wallet’s useful contribution is presenting the trade and its warnings before authorization; it is not a guarantee of an executable market for every displayed token.
