Alchemy

Alchemy is a blockchain infrastructure and developer platform headquartered in San Francisco, California. Founded in 2017 by Nikil Viswanathan and Joseph Lau, the company provides the APIs, node infrastructure, and developer tools that engineering teams use to build and scale applications on public blockchains.

Its core offering, Supernode, is a distributed node cluster with archival access, load balancing, automatic failover, and request caching that handles production-scale traffic without teams needing to run their own nodes. Alongside Supernode, Alchemy offers an NFT API, Token API, Portfolio API, webhook notifications, account abstraction tools, gasless transaction sponsorship, and stablecoin orchestration services. The platform supports over 100 blockchains, including Ethereum, Solana, Polygon, Arbitrum, Optimism, Base, and BNB Smart Chain.

Alchemy serves developers ranging from individual builders to large financial institutions. Clients include Robinhood, Visa, Stripe, Circle, OpenSea, Uniswap, and Chainlink. The platform reports 99.99% uptime and processes over one trillion dollars in transactions annually. In 2022 Alchemy acquired ChainShot, a Web3 education company, and later acquired Bware Labs to expand its European infrastructure presence.
