Alchemy Skill Pack

Claude Code skills for Alchemy Web3 blockchain development — NFTs, DeFi, multi-chain APIs (18 skills)

Alchemy is the leading Web3 development platform, providing blockchain infrastructure across Ethereum, Polygon, Arbitrum, Optimism, Base, and Solana. These skills use the real alchemy-sdk npm package with actual API methods: getBalance, getTokenBalances, getNftsForOwner, getAssetTransfers, Notify webhooks, and more.

Installation

Key Concepts

• Real SDK — All code uses alchemy-sdk npm package (import { Alchemy, Network } from 'alchemy-sdk')
• Compute Units — Alchemy bills by CU; skills include CU cost tables and optimization patterns
• Multi-chain — Factory pattern supporting ETH, Polygon, Arbitrum, Optimism, Base
• Never expose API key — All skills enforce server-side API key via proxy pattern
