About Alchemy
Alchemy is the leading blockchain developer platform, providing the infrastructure and tools needed to build scalable Web3 applications. Founded in 2017 by Nikil Viswanathan and Joe Lau, Alchemy powers major companies including OpenSea, Adobe, Shopify, and many top DeFi protocols.
The platform offers reliable node infrastructure for Ethereum, Polygon, Arbitrum, Optimism, Solana, and other major chains. Beyond basic RPC access, Alchemy provides enhanced APIs for NFTs, tokens, transactions, and webhooks. Their Supernode technology delivers higher reliability and lower latency than running your own nodes. Developer tools include the Alchemy SDK, blockchain explorer, mempool visualizer, and debugging tools.
Alchemy has processed trillions of requests and supports applications that have transferred over $100 billion in value. With a $10.2 billion valuation as of 2022, Alchemy has become the AWS of blockchain—essential infrastructure that most Web3 developers rely on. Their free tier makes it accessible for indie developers while enterprise plans scale to millions of requests.

Frequently Asked Questions
Alchemy is blockchain infrastructure that provides node access and APIs so developers don't have to run their own nodes. Running Ethereum nodes requires significant resources (TB of storage, constant syncing, DevOps). Alchemy handles this infrastructure while adding enhanced features like NFT APIs, webhooks, and debugging tools. Most major dApps use Alchemy or similar providers.
Running your own node gives full control but requires significant resources: hardware, storage (1-2TB for Ethereum), bandwidth, and ongoing maintenance. Alchemy's Supernode provides higher reliability (99.9%+ uptime), lower latency, enhanced APIs, and scales automatically. For most projects, using Alchemy is more cost-effective than self-hosting until you reach very high volumes.
Alchemy offers a generous free tier: 300M compute units/month, which covers most indie projects and early-stage startups. Paid plans (Growth, Scale, Enterprise) provide more compute units, higher rate limits, dedicated support, and advanced features. Many developers start free and upgrade as their apps grow.
Alchemy supports major chains including Ethereum, Polygon, Arbitrum, Optimism, Base, Solana, and more. Each chain has full RPC support plus chain-specific enhanced APIs. They continuously add new chains based on developer demand. Check their documentation for the current list of supported networks.
Account Kit is Alchemy's smart wallet infrastructure that enables account abstraction (ERC-4337). It allows dApps to offer gasless transactions (sponsor user gas), social login (sign in with email/Google), and programmable wallets. This improves UX by removing the need for users to manage seed phrases or hold ETH for gas.
