Need a smart contract that's secure, gas-optimized, and production-ready?
I'm Muhammad full-stack blockchain developer, founder of Blockhertz. 4+ years shipping contracts on Ethereum, Solana, Polygon, BSC, Base, and Arbitrum.
Most Fiverr contracts look fine but fail a basic Slither scan. Not here.

SECURITY-FIRST
Every contract checked against SWC Registry, fuzz-tested, and scanned before delivery. Audit-ready, not "works on my machine."
Message me before ordering with your requirements for a custom quote.

FAQ
Do you provide the audit report?
Basic tier includes a Slither scan summary. Standard includes full Slither + MythX report. Premium includes a formal audit-ready PDF. For a signed third-party audit (CertiK/Hacken level), I can refer you separately.
Will you deploy to mainnet?
Standard and Premium tiers include mainnet deployment support (you cover gas fees). Basic is testnet only — mainnet deployment available as an extra.
What if there's a bug after delivery?
All tiers include free bug fixes for code I wrote. Standard: 7 days. Premium: 30 days. This does not cover new feature requests.
Do you sign an NDA?
Yes, happy to sign an NDA before we discuss project specifics. Message me first.
Can you work with an existing codebase?
Yes , I can extend, refactor, or integrate with your existing contracts. Send me the repo and I'll scope it.
Which blockchain should I choose?
Message me your use case and I'll recommend based on your users, gas budget, and ecosystem needs. Common picks: Base or Polygon for low-cost EVM, Ethereum for max trust, Solana for high throughput.
