Core Transaction Flow

1. Fetching quotes

User flow begins with fetching quotes, which returns a list of quotes for the given input and output assets, along with the steps involved in the transaction. Quotes are by default sorted via best output and contains a scores object and tags to determine fastest/cheapest/best output routes. ​Get Quotes Documentation​

2. Creating a transaction

After fetching quotes, you can create a transaction using the selected quote by passing in the routeId of the quote. ​Create Transaction Documentation​
