Web3 & Blockchain Development Company in India
UniDev, based in New Delhi, India, builds production Web3 infrastructure — smart contract wallets, token launch platforms, NFT infrastructure, and DeFi staking systems — for protocols and startups shipping on-chain.
Smart Contract Wallets & Account Abstraction
We build ERC-4337 account abstraction wallets and Safe-based multi-sig custody systems that give users the same address across every EVM-compatible chain — with gas abstraction and session management built in for institutional-grade security.
Token Launches & DeFi Platforms
From Solana SPL token purchase flows with real-time pricing and server-side validation, to staking dApps shipped to mainnet, to cross-chain liquidity protocols — we handle the backend rigor token launches and DeFi products need.
NFT Infrastructure & Web3 Gaming
We build gas-optimized NFT minting and distribution systems, transaction bundling for bulk drops, and skill-based Web3 games with transparent, auditable on-chain prize distribution.
Case Studies & Results
Our Web3 portfolio includes a multi-chain smart wallet, a Solana token launch platform, a DeFi staking dApp live on mainnet, and a VC-backed NFT wallet with 40,000+ downloads. View our projects for the full breakdown.
