}Submits a contract source code to Optimism Etherscan for verification.
Requires a valid Optimism Etherscan API key, it will be rejected otherwise
Only supports HTTP POST due to max transfer size limitations for HTTP GET
Supports up to 10 different library pairs
Contracts that use "imports" will need to have the code concatenated into one file as we do not support "imports" in separate files.
List of supported solc versions, only solc version v0.4.11 and above is supported e.g. v0.4.25+commit.59dbf8f1
Upon successful submission you will receive a GUID (50 characters) as a receipt
You may use this GUID to track the status of your submission
Verified Source Codes will be displayed at the Verified Contracts page.
