Create Transaction

Create the transaction for current step

Create Transaction API

When a user starts swapping or when a step of swap succeeds, to get the transaction for the next step, this method should be called.

In multi-step routes, you should loop over the routeResponse.route array and call this method (createTransaction) per each step.

Typescript (SDK)

const transaction = await rango.createTransaction({
    requestId: "1978d8fa-335d-4915-a039-77f1a17315f5", // bestRoute.requestId
    step: 1,
    userSettings: {
        slippage: 3,
        infiniteApprove: false
    },
    validations: {
        balance: true,
        fee: true,
        approve: true
     },
})
