Verify Proxy Contract

Submits a proxy contract source code to Sophscan for verification.

Requires a valid Sophscan API key, it will be rejected otherwise
Current daily limit of 100 submissions per day per user (subject to change)
Only supports HTTP post
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 proxy contracts will display the "Read/Write as Proxy" of the implementation contract under the contract address's contract tab

Verifying Proxy Contract using cURL

// example with only the mandatory contract address parameter

// example using the expectedimplementation optional parameter
// the expectedimplementation enforces a check to ensure the returned implementation contract address == address picked up by the verifier
