FAQ
What do I need to verify a smart contract on Etherscan?
You need the source code, contract address, compiler version, optimization setting, and deployed address on a supported chain.
Do you support multi-file Solidity contracts?
Yes! I can flatten multi-file contracts using Remix or Hardhat if needed.
Can you verify contracts on Testnets (like Sepolia or Goerli)?
Absolutely, I can verify your smart contract on Ethereum testnets as well.
What if verification fails?
I’ll help troubleshoot and resolve the issue. If verification still fails due to incomplete source or wrong parameters, I’ll provide a detailed explanation.
Can you deploy the contract for me?
Deployment is not included, but can be discussed separately.
Can I request changes or add new requirements after the project starts?
Yes, I offer flexibility if your needs change. Minor adjustments are included, but if the scope expands (e.g., new features, contract redesign, or additional deployments), I’ll provide a custom offer so you only pay for the extra work you need. This way, everything stays fair and transparent.
