We've just launched OKX OS, the most comprehensive onchain infrastructure suite that opens up the tech stacks behind our Wallet, empowering a global community of developers to build and scale applications quickly across 100+ chains without limitations.
With hundreds of projects already leveraging the toolkit and processing more than 400 million daily API calls, our OKX OS provides a comprehensive set of tools, software development kits (SDKs) and APIs for building seamless onchain experiences, from wallets to games and DEXs. Supporting over 100 chains, including EVM networks, UTXO chains and mainstream homogeneous chains like Bitcoin and Solana, the toolkit enables developers to tap into diverse ecosystems and build on any chain.
Our OKX OS is already powering innovation across the onchain ecosystem, with projects such as Tomo Wallet, Zerion, Blade of God, Gravity and DuckChain leveraging our tools.
Developers can start using our OKX OS for free today. Following the launch, we plan to introduce developer support programs, global meetups and hackathons aimed at fostering onchain innovation and accelerating the growth of our OKX OS developer community.
