FAQ
Q1: Which blockchains do you support?
Ethereum, BSC, Polygon, Arbitrum, Avalanche, and Base. I recommend the best chain for your use case.
Q2: Do you provide the source code?
Yes. Full ownership of all Solidity, JavaScript, and configuration files upon delivery.
Q3: Is the smart contract audited?
I write audit-ready code with comprehensive tests. For formal third-party audit, I can connect you with partners or include it as a gig extra.
Q4: Can you build a custom token with taxes/burn/rewards?
Yes. I can implement any tokenomics model including deflationary mechanics, auto-liquidity, and holder rewards.
Q5: Do you build the frontend too?
Standard and Premium include a Web3 frontend. Basic is smart contract only.
How do I test before mainnet?
I deploy to testnet first. You interact with the full dApp, verify functionality, then approve mainnet deployment.
