About Helius
Helius is building the core infrastructure for Solana - empowering developers to create the next generation of crypto-powered applications. Our mission is to accelerate the development of internet capital markets by making it easier, faster, and more intuitive to build on-chain. Thousands of teams - from early-stage startups to industry leaders like Coinbase, Phantom, and Jupiter - rely on Helius APIs, webhooks, and indexing tools to power their products.
