Contract Verification - Constructor Arguments
When verifying the contract source code at {{explorer}} we require that you also provide us with the Constructor Arguments as they are automatically appended to the end of the contract source bytecode when the contract is compiled by Solidity.
API Key Rate Limit & Errors
During the enforcement of the API key requirement, developers will expect the return errors listed, where an API key is not in use or exceeding the rate limit.
Developer API Key 🔑
The {{chain}} Developer APIs are provided as a community service and supports both GET/POST requests and a rate limit of 5 requests/sec.
Update on Similar Match Contract Verification
Similar Match Contract Verification is a useful tool for verifying commonly reused contracts. However, the re-verification tool was previously exploited, leading to this update.
