The blockchain development landscape is evolving at breakneck speed. As decentralized applications (dApps) grow in complexity and user demand surges across multiple ecosystems, developers need a unified, scalable, and secure foundation to build upon. Enter OKX OS — a powerful onchain infrastructure suite designed to empower developers to create, deploy, and scale applications seamlessly across more than 100 blockchains.
Backed by the same robust technology that powers the OKX Wallet — one of the most widely used Web3 wallets globally — OKX OS opens up a full suite of tools, SDKs, and APIs to the broader developer community. Whether you're building a multi-chain wallet, decentralized exchange (DEX), NFT marketplace, or blockchain game, OKX OS delivers the flexibility and performance needed to thrive in today’s fragmented yet interconnected Web3 environment.
With over 400 million daily API calls processed and already trusted by hundreds of projects — including Tomo Wallet, Zerion, Blade of God, Gravity, and DuckChain — OKX OS is not just theoretical infrastructure. It's battle-tested, production-ready tech that scales with your ambitions.
Why OKX OS Stands Out in Web3 Development
Building on blockchain has traditionally involved navigating fragmented tooling, inconsistent documentation, and complex integration processes across chains. OKX OS eliminates these friction points with a unified approach to multi-chain development.
