About this Gig

A smart contract cant be quietly patched after launch. One bug can lock funds or drain a treasury, and contracts copied from templates often hide exactly that.


I build smart contracts and dApps for EVM chains, with clean code, real tests, and a working frontend when you need one.


What you get:

  • Custom Solidity contracts built on audited libraries like OpenZeppelin
  • Tests for normal use and edge cases
  • Testnet first, then mainnet deployment and source verification
  • React dApp with wallet connection when you need a frontend
  • Documentation of what the contract does and what the owner can change


I only build honest products: no hidden mint functions, no blacklist traps, nothing designed to trap buyers.


For contracts holding real money, I recommend an independent audit before launch.


Send me what the contract should do, which chain, and who can call what. Ill scope it before you order.
