How are transactions imported?

The app uses blockchain explorer APIs (Etherscan, Solscan, Blockstream) to fetch transaction history for connected wallet addresses. No manual import required.

How are DeFi balances tracked?

The app calls protocol-specific APIs or on-chain contract read methods to fetch your LP positions, staked balances, and yield farm holdings across integrated DeFi protocols.

How do price alerts work?

Set a price target (above or below) for any token in your watchlist. The system polls prices on a schedule and sends email or push notifications when the threshold is crossed.

The Challenge

Why building a Crypto Wallet from scratch is hard

Building a Cryptocurrency Wallet Application from scratch requires months of development time and significant engineering resources. Teams struggle to coordinate frontend, backend, database, and authentication while managing crypto wallet-specific business logic, integrations, and role-based access rules.

What's Included

Everything your Crypto Wallet needs

ProjectCode generates a production-ready Crypto Wallet with all the modules your team needs from day one.

Multi-chain wallet: Ethereum, Solana, Bitcoin, Polygon

Receive and send crypto with QR code support

Real-time portfolio valuation in fiat currency

Transaction history with gas fee breakdown

NFT gallery viewer per wallet address

DeFi protocol portfolio integration

Security: hardware wallet connect and 2FA

Price alerts and watchlist for tokens

Architecture

How it's built

The generated Crypto Wallet follows production-grade architecture patterns.

React 18 + TypeScript frontend with role-based dashboards tailored for crypto wallet workflows

NestJS REST API with dedicated crypto wallet modules, DTOs, validators, and service layer

PostgreSQL relational schema with normalized tables for all crypto wallet entities

JWT + Google OAuth authentication with granular permission gates per role

Real-time Socket.IO events for live crypto wallet status updates and notifications

Managed hosting with one-click deploy, custom domain, and auto-SSL

Database

PostgreSQL schema designed for Crypto Wallet

ProjectCode generates a normalized, indexed PostgreSQL schema with the right tables and relationships for your use case. You own the schema and can evolve it freely.

wallets (id, user_id, address, chain, type, label, added_at)
transactions (id, wallet_id, hash, type, from_address, to_address, value, token, gas_fee, timestamp, status)
portfolio_snapshots (id, user_id, date, holdings jsonb, total_value_usd)
watchlist (id, user_id, token, chain, alert_above, alert_below, created_at)
