Describe the feature you would like

We currently have a lot of code in place to handle multichain Etherscan verification due to the different endpoints and API keys associated with each.

With the release of Etherscan V2 there is now a single unified API endpoint: https://docs.etherscan.io/etherscan-v2 accessible with a single API key

Additional context

It is currently still in beta but worth exploring

Part of this ticket would be to double check if there are no breaking changes in the V2 API

Note: it requires passing a ?chainid=n as a parameter where n is the chain id: https://docs.etherscan.io/etherscan-v2/getting-started/v2-quickstart#if-youre-coming-from-v1
