How to develope dex on 1 inch plugin

Hi could you assist me with how to developing Dex on binance. so far I have achieved as above attached screenshot.
I need to know that what is the gas price to be set and how to setup settings and transactions history buttons? On token swap page

Thank you

Assuming that the user is signed in.
For Transaction History, you can use the web3NativeApi it would be something like this:

const options = { chain: "bsc" };
const transactions = await Moralis.Web3API.account.getTransactions(options);

If you have more questions about the customization of this query please look at https://docs.moralis.io/moralis-server/web3-sdk/account.

To check DEX specific code all can be see here
https://moralis.io/plugins/1inch/ . The main functions should explain how to do a swap. if you have any function related questions feel free to reply
