Feature Title
Dynamic coin selection algorithm functionality
Feature Description
This feature aims to implement a coin selection algorithm into the TransactionBuilder to automatically select the most efficient set of unspent transaction outputs (UTXOs) from the the provided inputs (ideally all of the user's wallet utxos) for constructing transaction.
The algorithm should ensure that the selected UTXOs minimise transaction fees and improve overall transaction efficiency, including the handling of native tokens.
Use Case
This feature will optimise transaction fees and improve overall performance, especially when dealing with native tokens. The automatic selection of UTXOs will streamline the transaction creation process, making it more user-friendly and efficient.
