Develop a complete, multi-chain wallet portfolio tracker using Alchemy's Enhanced APIs. This workflow aggregates ETH balances, ERC-20 token holdings, NFT assets (ERC-721/1155), and transaction history across major chains (Ethereum, Polygon, Arbitrum, Optimism, Base). Ideal for building sophisticated decentralized applications (dApps) and comprehensive Web3 dashboards.

A comprehensive guide to production-ready patterns for Web3 development using the Alchemy SDK. Covers essential architectural components such as multi-chain client factories, response caching mechanisms, type-safe NFT query builders, and robust error classification, ensuring highly scalable and reliable blockchain applications.

This skill implements Alchemy Notify webhooks to provide real-time, event-driven notifications for on-chain activities. Instead of continuous polling, it allows applications to receive callbacks for wallet transfers, confirmed transactions, dropped transactions, or NFT events. Use it for building real-time dApp features, monitoring critical wallet activity, or integrating payment confirmations into your blockchain applications.

This workflow demonstrates how to interact with specialized NFT and ERC-20 token APIs provided by QuickNode. It provides programmatic methods to fetch detailed metadata, check current token balances, and track comprehensive transfer history for blockchain assets. It is essential for developers building decentralized applications (dApps) or integrating advanced Web3 features into their product.
