#This is an example of how to determine the structure of the datum files to use with your eopsin custom datums. 

#ExampleDatumStructure in Eopsin contract:

#Import the dataclass from the eopsin python file
#We will use the policy_id and policy_name in hex encoding so we will convert our policy using bytes.fromhex()
