{% hint style="info" %} Note that if Nusa is unable to complete the transaction due to a force major such as the difference between the market price and the quoted price from our liquidity sources for the tokens you wish to swap exceeds the slippage tolerance on the interface, Nusa will return in which the equivalent USDT/USDC/destination native token. {% endhint %} **Please refer to the example below.** * Firstly, Alice receives a quotation by using Nusa Cross-Chain Swap, which has been\ instructed to search for and single out the best route for Bob. For instance, **1.000 BSC\_NUSA** could be swapped for **150.788.820 POLY\_IDRX** in return and with a 1% slippage tolerance. If Alice accepts the quoted price, he will submit a **TX** request, namely **TX1** * Nusa will convert trade **1.000 BSC\_NUSA** for the best offer **9.190 USDT**. * Nusa will charge some fees and then submit a transaction request to swap\ **9.190 BSC\_USDT** for **POLY\_IDRX**. * Nusa will swap **BSC\_USDT** for **POLY\_IDRX** via multiple DEXes for the best return * Once successfully traded, **POLY\_IDRX** will be transferred to Alice.\ However, if, unfortunately, the price of **POLY\_IDRX** suddenly fluctuates following **TX1** and\ the swap fails to swap **1.000 NUSA** to Bob, then Nusa will instead transfer **29.980 BSC\_USDT t**o Alice, who still gets his assets back, safe and sound. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
