FAQ
Which blockchains do you support?
All EVM chains, including Ethereum, Polygon, BNB Chain, Arbitrum, Optimism and Base. Solana (Rust) or other chains are available as a custom offer.
Is this a security audit?
No. I follow best practices and test thoroughly, but this is a development gig, not a formal audit. For contracts that will hold significant funds, I recommend an independent audit and can prepare the code for it.
Do I own the code?
Yes. You get the full source code and all rights after delivery and payment.
Can you fix or extend an existing contract?
Yes. Send me the code before ordering and I’ll quote a review, fix, or extension as a custom offer.
Do you also build the front end?
Yes, see my “Full dApp” gig, or message me for a bundled offer.
What happens after delivery?
Support days cover bug fixes within the delivered scope. New features are quoted separately.
