Some Etherscan verified contracts do not have optimizer field in their compiler settings.
For example, contract 0xd689a304011d64d5bf1d662d9cddf8b2db81e6b6, the compiler settings given by Etherscan is

"settings": {
    "outputSelection": {
      "*": {
        "*": [
          "evm.bytecode",
          "evm.deployedBytecode",
          "abi"
        ]
      }
    }
  }
}

However, the optimizer field in the Setting struct is not optional, leading to a crash when fetching compiler settings for this contract.

Right now we're coupled to ethers due to using RawAbi, and the Chain enum. This means we need to keep patches on foundry to keep ethers versions in sync. We should remove the dep as follows:

• Integrate alloy-rs/chains when ready
• Move RawAbi into block-explorers, as it's not an alloy-related type nor an RPC type. It just uses some metadata from the ABI for verification purposes.

with #42 we now have a few blobscan api functions but we're missing a few more

as well as partial responses for queries

While trying to implement a cast command to migrate a contract verification from on explorer to another (specifically from etherscan to blockscout), I encountered the issue that the contract_source_code and submit_contract_verification methods fail when run against blockscout. (more specifically against "https://eth.blockscout.com/api".

I created tests reproducing the issue for contract_source_code and submit_contract_verification.

Judging from the error messages (see screenshots), the former issue seems to be a pretty strait forward deserialziation issue whereas the latter has a pretty cryptic error message.

Hi, I'm using this library to get the ERC20TokenTransferEvent from etherscan and then save it into a JSON file.
But when deserialize the JSON file, I had this Error value: Error("digit 33 is out of range for base 16", line: 3, column: 39)'. It seems like the number in the JSON file is saved in the hex format.
Can someone help me to solve this issue?

Test code

        let client = Client::new(Chain::from_id(137), "<API-KEY>>").unwrap();
        let addr = Address::from_str("<Address>").unwrap();

        let events = client
            .get_erc20_token_transfer_events(
                foundry_block_explorers::account::TokenQueryOption::ByAddress(addr),
                Some(foundry_block_explorers::account::TxListParams {

                }),
            )
            .await
            .unwrap();

        let data = serde_json::to_string_pretty(&events).unwrap();

        println!("{}", data);

        let de_events: Vec<ERC20TokenTransferEvent> = serde_json::from_str(&data).unwrap();

        assert_eq!(events.len(), de_events.len())
    }
