The Web3 landscape is evolving at lightning speed, and developers are in constant need of robust, scalable, and flexible infrastructure to build the next generation of decentralized applications. Recognizing this demand, OKX, a global leader in cryptocurrency and Web3 technology, has unveiled OKX OS — a comprehensive multi-chain development engine designed to empower builders across more than 100 major public blockchains.
Built by the same team behind the OKX Web3 Wallet, OKX OS opens up the underlying technology stack that powers one of the most widely used self-custody wallets in the industry. This strategic move gives developers direct access to battle-tested tools, APIs, and SDKs that have already proven their scalability — currently supporting over 400 million API calls per day and serving hundreds of integrated projects.
Whether you're building a decentralized exchange (DEX), NFT marketplace, blockchain game, or cross-chain wallet, OKX OS delivers a unified infrastructure layer that simplifies development and accelerates time-to-market.

Why OKX OS Stands Out in the Web3 Ecosystem
Web3 development has long been hindered by fragmentation — differing standards across chains, inconsistent data formats, and limited tooling support. OKX OS addresses these challenges head-on with a developer-first approach focused on interoperability, scalability, and ease of integration.
With support for EVM-compatible networks, UTXO-based chains, Bitcoin layer-2 solutions, Solana, and many others, OKX OS enables seamless cross-chain development without the need for complex middleware or redundant codebases.
Core Benefits for Developers
- One-stop toolkit: Access a full suite of APIs and SDKs to build wallets, games, DEXs, NFT platforms, and more.
- Multi-chain liquidity aggregation: Bridge gaps between chains by tapping into aggregated liquidity across 20+ networks and over 500 decentralized exchanges.
- Bitcoin ecosystem innovation: Unique tooling for inscriptions, runes, fractal Bitcoin, and other emerging Bitcoin-native technologies.
- Enterprise-grade security: Leverage the same audited security protocols and infrastructure that protect millions of OKX users.
- Proven scalability: Built for growth — already handling massive traffic with real-world performance validated by daily 400M+ API calls.
These capabilities aren’t theoretical — they’re actively being used by real projects like Tomo Wallet, Zerion, Blade of God, Gravity, and DuckChain, all leveraging OKX OS to enhance functionality and user experience.
