Hire the Best Smart Contracts Developers
in India

Blockchain & AI Agent Developer specializing in Solana, Ethereum, Rust, Solidity, Smart Contracts, Agentic AI, and Web3 Infrastructure. I build blockchain systems and AI agents that work in production not just on testnet. My core focus is the intersection of Web3 and Agentic AI smart contracts, autonomous AI agents, and on-chain payment infrastructure. I've deployed on Ethereum, Polygon, Solana, and XPR Network, and built everything from NFT marketplaces to full Layer-1 blockchain ecosystems. What I build: Agentic AI & x402 Payment Infrastructure — Autonomous AI agents that transact on-chain using the x402 HTTP payment protocol, enabling machine-to-machine micropayments without human intervention. Solana-Like Blockchain Ecosystem — Full Layer-1 chain with consensus mechanism, validator nodes, and staking logic built from scratch. NFT Marketplace — Minting, listing, and trading platform with custom smart contracts across multiple EVM chains. Student Certificate Verification DApp — Decentralized credential system using Ethereum + Hyperledger. WASM Smart Contracts on XPR Network — C++ based contracts deployed on-chain. Technical stack: Solidity, Rust, React.js, Node.js, Web3.js, Python, IPFS, Hyperledger, MongoDB — plus AI/ML frameworks for agent development and automation. I work with founders and dev teams building at the edge of blockchain and AI where autonomous systems need to interact with on-chain infrastructure. If your project involves AI agents, Web3 payments, or smart contract systems, I understand both layers. Let's scope your project.

Smart Contract Engineer specializing in Solidity and DeFi systems on Ethereum and EVM chains. I build secure smart contracts, staking systems, token ecosystems, and Web3 applications with a focus on security, gas optimization, and production-ready architecture. I design and implement production-grade smart contracts for lending, staking, vesting, and token ecosystems — with a strong focus on collateralization logic, liquidation safety, gas efficiency, and protocol-level security. I don’t build demos. I build systems where real value is at risk, and correctness, safety, and clarity matter. 🔹 What I build DeFi lending protocols (collateral, LTV enforcement, health factor, liquidation, interest accrual) Staking & reward systems (finite reward pools, safe accounting, no infinite minting) Vesting contracts (cliff + linear vesting, founder & investor-safe designs) ERC20 token contracts (custom logic, controlled mint/burn, secure allowance handling) Security-focused smart contract architecture (reentrancy protection, access control, CEI pattern, protocol invariants) Smart contract integration (ethers.js, wallet interactions, transaction flows) 🔹 How I work I think in protocol flows and invariants, not just individual functions I identify edge cases and security risks early I explain technical trade-offs clearly to non-technical stakeholders I write code that is testable, auditable, and maintainable I’m comfortable working independently or with distributed teams 🔹 What you can expect Clean, well-documented Solidity code Security-first design decisions Clear communication and realistic timelines Honest feedback on risks and limitations Long-term maintainability over shortcuts 🔹 Let’s work together If you’re building a Web3 product that involves real asset flow, DeFi logic, or security-critical smart contracts, I can help you design and implement it correctly from day one. I’m happy to review your idea, point out potential risks, and suggest a solid technical approach before any code is written.
