Module xdr_utils

XDR utility functions for Stellar transaction processing.

This module provides utilities for parsing, validating, and manipulating Stellar transaction XDR (External Data Representation) structures. It includes support for regular transactions, fee-bump transactions, and various transaction formats (V0, V1).

Functions

attach_signatures_to_envelope
