4 - Execute swap
This is the last step in the swap process. This step contains the transactions that will execute the swap.
From Build swap tx, you get a response containing the transactions that need to be executed in order to complete the swap. This response contains an array of transactions that need to be executed in the same order.
The reason why you might need to execute multiple transactions for a swap is because it might be necessary to approve
a contract to spend tokens for executing a swap.
Prepare transactions
Given the response from step 3 - Build swap tx:
