Web3 Infrastructure & On-Chain SystemsHira Saleem
I build secure and scalable Web3 infrastructure, focusing on on-chain systems rather than surface-level dApps. My work includes wallet integration, smart contract systems, and on-chain logic designed for real-world use cases such as gaming, platforms, and decentralized products. The emphasis is on reliability, security, and long-term maintainability.
What's included
Stage 1: Architecture & On-Chain Design
On-chain system architecture
Contract interaction flow
Security considerations and upgrade strategy
Stage 2: Smart Contract Development
Core smart contracts (logic, permissions, assets)
Modular and upgrade-aware design
Unit tests and validation
Stage 3: Wallet & User Interaction Layer
Wallet connection (MetaMask, WalletConnect, etc.)
Transaction handling and state management
Gas optimization and UX considerations
Stage 4: Deployment & Validation
Testnet and mainnet deployment
Contract verification
