What is `MasterCopies` and `ProxyFactories`? Do I have to add my contracts to safe-eth-py

[arpitkarnatak]

I've got my networks added on to safe-singleton-factory and got my contracts added to safe-smart-accounts. These are the addresses of my deployed accounts (same as the addresses on other networks)

In the step 4 of docs for running locally

Step 4: Add your MasterCopies and ProxyFactories

By default, tx service will auto setup MasterCopies and Proxy Factories for [a of networks](https://github.com/safe-global/safe-eth-py/blob/main/gnosis/safe/addresses.py). If your network is not supported you have to add the addresses manually in http://localhost:8000/txs/admin/

What are MasterCopies and ProxyFactories? Is it a separate contract, or are MasterCopies the contracts Safe and SafeL2 and ProxyFactories contract SafeProxyFactory respectively

No. It is not related. The first one is contract deployment while the second one belongs to infra deployment. Do have a look on this video.

Although it is outdated, it still able to solve your issue.
