Alchemy

A blockchain developer platform providing enhanced node APIs, debugging tools, and NFT data for Ethereum and other chains.

Alchemy — Alchemy is a blockchain developer platform that provides node infrastructure, enhanced APIs, and developer tools for building Web3 applications. It supports Ethereum, Polygon, Solana, Arbitrum, Optimism, Base, and over 20 other networks, offering features beyond basic RPC access including NFT APIs, transaction simulation, and webhook notifications.

What Is Alchemy?

Alchemy provides the backend infrastructure that powers thousands of Web3 applications. Its core product is a managed node service that handles JSON-RPC requests, but it extends well beyond basic connectivity. The platform includes enhanced APIs for token balances, NFT metadata, transaction receipts, and trace data — queries that would require complex indexing if built independently.

Founded in 2017, Alchemy serves major clients including OpenSea, Aave, and Dapper Labs, processing tens of billions of compute units weekly.

Alchemy's Developer Tools

Beyond RPC endpoints, Alchemy offers a Supernode architecture with built-in redundancy, Notify webhooks for real-time transaction monitoring, and the Transfers API for tracking token movements. Its Account Kit simplifies ERC-4337 account abstraction integration, and Alchemy's free Modular Account provides gas sponsorship and session key support out of the box.

Alchemy in DeFi Infrastructure

DeFi protocols, trading bots, and analytics dashboards depend on reliable, low-latency RPC access. Alchemy's infrastructure routes requests through geographically distributed nodes, offering sub-100ms response times. For high-frequency operations like volume generation and market making, consistent RPC performance is critical to avoid failed transactions and missed opportunities.

Frequently Asked Questions

Common questions about Alchemy in cryptocurrency and DeFi.

Both provide RPC access, but Alchemy includes enhanced APIs (NFT, Transfers, Debug), built-in analytics, and developer tools like webhooks. Infura has deeper Consensys integration. Many teams use both for redundancy.

Alchemy's free tier includes 300 million compute units per month, which is sufficient for development and small production apps. Growth and Scale plans offer higher limits and priority support.

Yes. Alchemy added Solana support and provides both standard RPC and enhanced APIs for Solana, including token balance queries and transaction history. However, Helius remains the most Solana-specialized provider.
