Skill UI

A comprehensive guide for building production-grade Web3 applications, smart contracts, and decentralized systems. Covers expertise in DeFi protocols, NFT platforms, DAOs, cross-chain interoperability, and advanced smart contract security patterns (Solidity, Rust). Ideal for developers building complex, resilient decentralized finance (DeFi) and enterprise-grade blockchain solutions.

This skill provides comprehensive guides and code templates for implementing major NFT standards, including ERC-721 and ERC-1155. It covers best practices for metadata (on-chain and IPFS), managing token supply, implementing complex features like royalties, and building various types of digital collectibles and gaming assets on the blockchain.

A comprehensive utility designed to monitor, analyze, and predict blockchain gas costs across multiple major chains (e.g., Ethereum, Polygon, Arbitrum). It fetches real-time pricing, estimates transaction costs in both ETH and USD, and identifies the optimal time windows for executing DeFi or NFT transactions, ensuring maximum cost efficiency.

Automate Venly operations via the Composio Rube MCP stack by discovering current tool schemas, validating connections, and executing schema-compliant actions for NFT and wallet workflows.

This tool generates a comprehensive debug bundle for troubleshooting Alchemy SDK issues. It collects crucial diagnostic evidence, including connectivity tests for core, enhanced, and NFT APIs, network status across multiple chains (Ethereum, Polygon, Arbitrum), SDK version, and environment details. Use it when encountering complex blockchain query failures or preparing detailed support tickets for reliable issue resolution.

This comprehensive guide details advanced strategies for optimizing performance when interacting with blockchain data using the Alchemy SDK. Techniques covered include implementing TTL-based caching for data freshness, achieving parallel multi-chain fetches, utilizing batch API calls (e.g., NFT metadata) to reduce Compute Unit (CU) costs, and adopting WebSockets for real-time event subscriptions. Essential for scaling robust, low-latency dApps.

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.

A comprehensive workflow for building NFT collection explorers and interacting with smart contracts using Alchemy's robust APIs. It covers fetching detailed NFT metadata (including OpenSea data and floor price), batch processing metadata, reading standard contract states (like ERC-20 balances), and verifying NFT ownership. Ideal for developing advanced Web3 applications, marketplaces, and data dashboards.

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 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.

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.
