Projects using MongoDB in Islamabad Capital TerritoryProjects using MongoDB in Islamabad Capital TerritoryI developed Noottools, a multi-chain crypto wallet app built for users to manage, send, receive, swap, and track digital assets across multiple blockchain networks.
The wallet supports major networks including Bitcoin, Solana, Tron, Ethereum, BSC, Base, Polygon, and Sonic. Users can manage their crypto portfolio, view token balances, send and receive assets, swap tokens, explore NFTs, connect wallets, and interact with dApps through WalletConnect.
I built the core wallet experience with a clean mobile interface, portfolio tracking, QR-based receive flow, wallet address display, copy/share address, token management, NFT support, swap functionality, and Web3 connectivity. The app was designed to make blockchain transactions simple for everyday users while still supporting advanced Web3 features.
This project focused on crypto wallet development, blockchain wallet integration, multi-chain wallet support, Web3 app development, DeFi wallet features, NFT wallet functionality, WalletConnect integration, dApp connectivity, token swaps, crypto portfolio tracking, and secure digital asset management.
