About this Gig
Need a reliable blockchain developer who has actually shipped real projects?
I build Solidity smart contracts and Web3 dApps on Ethereum from simple token contracts to complex multi-party systems with full frontend integration.
What I can build
Smart contracts (Solidity 0.8.x):
- Voting and governance systems
- Marketplace and escrow contracts
- Token contracts (ERC-20, ERC-721)
- Access control and role management
Web3 frontend (ethers.js / Web3.js):
- MetaMask wallet integration
- Live on-chain data display
- Transaction signing and confirmation flow
- React.js or plain HTML/JS your choice

- Testnet deployment with verified contract address
- Full source code + ABI + deployment guide
- Clean, commented code you can maintain yourself

FAQ
Will I own the full source code?
Yes. You receive complete ownership of the Solidity contract, frontend code, and ABI. No lock-in, no recurring fees.
What blockchain network do you deploy on?
I deploy on Ethereum Sepolia Testnet by default. Mainnet deployment is available as a paid extra. I can also adapt contracts for other EVM-compatible chains — message me to discuss.
Can the contract be deployed on mainnet?
Yes — mainnet deployment is available as a gig extra. You cover the gas fees, I handle the deployment and provide the verified contract address.
