FAQ
Which blockchain networks do you support?
I develop for all EVM-compatible networks, including Ethereum, Binance Smart Chain (BSC), Polygon, Arbitrum, Optimism, Avalanche, and Base.
Do you verify the smart contract on Etherscan/BscScan?
Yes! I will provide the exact source code files and can guide you through the verification process so your users can interact with your contract directly on the block explorer.
Will you test the smart contract for vulnerabilities?
Absolutely. Security is the highest priority in Web3. I run extensive local unit tests using modern frameworks to check for reentrancy, integer overflows, and basic access control vulnerabilities before anything goes live.
