decodePSBT

Overview

The 'decodePSBT' method is utilized to decode a PSBT (Partially Signed Bitcoin Transaction) into a human-readable format, providing detailed information about the transaction in JSON format. This method is essential for developers and users who want to understand the transaction details before it is broadcasted to the network.
