Does the CLI handle deploying multiple proxies with a shared implementation contract?

Hi,
I would like to deploy multiple proxies that share the same implementation contract (and also same ProxyAdmin) via openzeppelin cli, is it something supported out of the box?

Thanks

Hi @bugduino,

Yes. When deploying via the OpenZeppelin CLI in one project, the implementation contract should be deployed once and the ProxyAdmin should be shared.

You can try it out yourself.

I deployed MyContract twice as upgradeable, the implementation contract was deployed the first time and so was the ProxyAdmin.

$ npx oz deploy
Nothing to compile, all contracts are up to date.
