Migrate to Blockscout for L2 Block Explorer Needs #1131
Description
We are migrating to Blockscout for OP Mainnet and OP Sepolia. It appears that this repo currently uses Etherscan for checking verified contracts.
This issue is primarily to do a find every OPM or OP Sepolia reference to Etherscan, replacing with Blockscout. We should also make sure any contracts we are relying on are already verified on Blockscout.
This needs fairly minimal changes to the verification script:
--verifier blockscout
--verifier-url { https://explorer.optimism.io/api/ | https://testnet-explorer.optimism.io/api }
I don't believe you need an API key for blockscout verification.
