Verify Source Code

Submits a contract source code to Etherscan for verification.
See Demo Source Verification Submission Code at Source Code Verification Sample.
  1. 1.
    Requires a valid Etherscan API key, it will be rejected otherwise
  2. 2.
    Current daily limit of 100 submissions per day per user (subject to change)
  3. 3.
    Only supports HTTP POST due to max transfer size limitations for HTTP GET
  4. 4.
    Supports up to 10 different library pairs
  5. 5.
    Contracts that use "imports" will need to have the code concatenated into one file as we do not support "imports" in separate files.
  6. 6.
    List of supported solc versions, only solc version v0.4.11 and above is supported e.g. v0.4.25+commit.59dbf8f1
  7. 7.
    Upon successful submission you will receive a GUID (50 characters) as a receipt
  8. 8.
    You may use this GUID to track the status of your submission
