Check the destination network and token shown in the quote. Do not assume that similarly named assets are interchangeable across networks or that every route is available at every moment.
Network gas, liquidity, route selection and provider fees can affect the amount received. The live quote is the best reference for the transaction you are about to sign.
StarBridge is a non-custodial interface. Connect your wallet, review the route and approve the transaction yourself. Never sign a transaction that does not match your intended asset and destination.
