I stored a number of Solana transaction signatures in a text file for later processing.

I am using python and the solders sdk/api.

I converted the signature to a string using str(..). I then wrote it to a text file.

When I now read the signature back in and try to use it as a signature in

from solders.signature import Signature
from solana.rpc.api import Client

….

sig = Signature.from_string(array[ptr])
info = connection.get_transaction(sig, max_supported_transaction_version=0)

I get

Traceback (most recent call last):
File “C:UsersTimDocumentssolanaprocessSigs.py”, line 35, in
sig = Signature.from_string(array[ptr])
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ValueError: string decoded to wrong size for signature

……

I dont know how to get a signature from a string other than using the from_string function.

This is the signature i am working with – its public information so no need for secrecy

Can you help me please.

Tim.

I havent tried anything else as I was sure fron_string would work.
