A comprehensive guide for migrating code from deprecated libraries like alchemy-web3 to the modern alchemy-sdk (v3). This resource details handling breaking changes, understanding new API namespaces (core, nft, ws), and updating web3 interactions to ensure seamless blockchain functionality.

This guide provides minimal, working examples using the Alchemy SDK for foundational Web3 development. Learn essential blockchain interactions, including checking ETH balances, fetching NFT collections for a wallet, retrieving ERC-20 token balances, and querying the latest block information. Ideal for developers starting out or testing their blockchain infrastructure.

A utility designed for robust blockchain interactions using the Alchemy API. It implements CU-aware throttling based on Compute Unit costs, manages concurrent requests, and includes advanced retry logic for handling 429 Too Many Requests errors. Ideal for optimizing high-volume, reliable Web3 applications that must adhere to strict API rate limits and usage budgets.

A comprehensive guide for diagnosing and fixing common errors encountered when using the Alchemy SDK and Web3 APIs. Covers issues such as authentication failures (401/403), rate limits (429), invalid parameters, RPC failures, and specific NFT/Enhanced API errors. Ideal for developers integrating blockchain functionalities.

This integration facilitates the secure deployment of Alchemy-powered decentralized applications (dApps) across major cloud platforms like Vercel and Google Cloud Run. It is designed to ensure that sensitive Alchemy API keys are treated as server-side secrets, preventing client-side exposure. Use this when setting up backend services, RPC proxies, or deploying production-grade Web3 applications requiring secure access to blockchain data.

This guide provides step-by-step instructions for installing the Alchemy SDK and setting up secure API key authentication. It details how to connect to multiple major blockchain networks (including Ethereum, Polygon, Arbitrum, etc.) using Alchemy's robust infrastructure. Essential for developers building decentralized applications (dApps) that require scalable, multi-chain RPC access.

A comprehensive, multi-chain reference architecture for building robust decentralized applications (dApps) powered by Alchemy. This guide outlines the full stack, from the React/Next.js frontend and API layer to core blockchain interactions, incorporating best practices like rate limiting, caching, and secure API proxying. Ideal for planning complex, production-grade Web3 systems across multiple chains (ETH, Polygon, etc.).

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.

A comprehensive guide to securing Web3 applications utilizing Alchemy. It covers critical best practices, including implementing secure API key proxies, managing private keys via secret vaults, validating blockchain inputs (addresses, block numbers), and verifying webhook signatures to harden your dApp infrastructure.

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 skill provides implementation patterns for integrating with QuickNode, utilizing blockchain RPC endpoints and the QuickNode SDK. It guides developers on connecting, checking block numbers, and interacting with the Ethereum/Web3 blockchain infrastructure. It is crucial for any developer working on decentralized applications or CI/CD pipelines that require reliable blockchain access.

A comprehensive guide for developers to diagnose and fix common blockchain RPC errors when utilizing QuickNode endpoints. Covers issues such as 'Nonce Too Low', 'Insufficient Funds', 'Gas Estimation Failed', and 'Rate Limited' errors, providing concrete code fixes using ethers.js or viem.
