I will develop secure smart contracts and blockchain dapps in solidity
Full Stack Developer, Blockchain and AI, React, Python, Smart Contracts
I build production-grade software — blockchain protocols, AI systems, and full-stack apps.

→ AI agents & automation (Python, LangChain, cust...
About this Gig
I build smart contracts and dApps that are secure, gas-optimized, and production-ready not copy-paste templates.
I write custom cryptographic protocols from scratch, including zero-knowledge proof systems (Groth16/zkSNARKs).
What you get:
Custom smart contracts (ERC20, ERC721, ERC1155, or your own logic)
Full dApp smart contract + React/Next.js frontend + wallet connect
Zero-knowledge proof implementations for privacy and verification
Smart contract auditing and gas optimization
Token creation, deployment, and verification on any EVM chain
Multi-chain support: Ethereum, Polygon, Arbitrum, Base, BSC
Why me:
Deep cryptography I implement ZKP circuits (Groth16 on BN128), not tutorials
Rust + Solidity + C I work at the protocol level
Full-stack I build the contract AND the frontend
Security-first: reentrancy guards, formal patterns, gas optimization
I've built production ZKP identity verification systems with sub-3-second end-to-end proof generation.

FAQ
Which blockchains do you support?
I work with all major EVM-compatible chains: Ethereum, Polygon, Arbitrum, Base, BSC, Optimism, Avalanche, and others. For non-EVM chains like Solana, I work in Rust. Message me with your chain of choice and I'll confirm support.
How do you ensure the smart contract is secure?
Every contract I write follows OpenZeppelin best practices, includes reentrancy guards, access control, and gas optimization. I write a full test suite (Hardhat or Foundry) covering edge cases. The Premium package includes a dedicated security audit. I don't deploy templates — I write custom, audita
What is a zero-knowledge proof and do I need one?
A zero-knowledge proof lets you prove something is true without revealing the underlying data — for example, proving you're over 18 without sharing your birthdate. If your project involves privacy, identity verification, or confidential data on-chain, ZKP is the right tool. If you're unsure, message
Do you also build the frontend for the dApp?
Yes. I'm a full-stack developer — I build both the smart contracts and the React/Next.js frontend with wallet integration (MetaMask, WalletConnect). The Standard and Premium packages include a complete dApp. For Basic, you can add a frontend as an extra.
Who pays for the gas fees to deploy the contract?
Gas fees for mainnet deployment are paid by you, as they go directly to the blockchain network. I'll deploy on testnet first (free) so you can verify everything works perfectly before going live. I'll guide you through the entire process.
