[Feature] Support for Proxy Contracts #1739

Open schmidsi opened 1 week ago

schmidsi commented 1 week ago

Currently, when running graph init and trying to scaffold a subgraph indexing a proxy contract, the CLI is not aware of the implementation contract. This is a big caveat for new devs since often, the first contract they want to index is indeed a proxy.

I think this is solvable at the CLI level: Detect if a contract is a proxy contract and if so, present an option to look at the current implementation contract and get the ABI from it to scaffold out the subgraph entities.
