Powering the Next Generation of Web3 Developers
As of launch, OKX OS is already being leveraged by hundreds of projects and handles over 400 million API calls daily—a testament to its scalability, reliability, and real-world utility. By offering a unified infrastructure layer, OKX OS eliminates the complexity traditionally associated with multi-chain development.
“With OKX OS, we’re opening access to technology that can attract millions of on-chain users,” said Haider Rafique, Chief Marketing Officer at OKX. “Our goal is to provide developers with the most comprehensive toolkit in the industry, enabling them to build scalable applications quickly on any blockchain.”
The platform’s architecture is built around three core principles: accessibility, interoperability, and speed-to-market. Whether you're building a cross-chain DeFi protocol or a Bitcoin-ordinals-powered NFT marketplace, OKX OS provides the foundational tools needed to go from concept to deployment faster than ever.
Why Developers Are Choosing OKX OS
Unified Tooling Across 100+ Blockchains
Gone are the days of stitching together disparate SDKs and APIs for each chain. OKX OS offers a one-stop solution for developing complex on-chain applications across wallets, games, DEXs, NFT platforms, and more. This unified approach reduces development overhead and accelerates product iteration.
Multi-Chain Support & Liquidity Aggregation
OKX OS supports over 100 popular public chains and aggregates liquidity across decentralized exchanges and NFT markets. This means developers can create applications that offer users instant access to deep liquidity pools without being locked into a single ecosystem.
For example:
- A DeFi app can route trades through multiple DEXs across Ethereum, Arbitrum, and Base.
- An NFT marketplace can display real-time listings from OpenSea, Blur, and Magic Eden—all within a single interface.
This cross-chain liquidity layer is critical for delivering smooth, user-friendly experiences in a fragmented Web3 landscape.
Bitcoin Ecosystem Innovation
OKX OS stands out with its native support for Bitcoin-layer innovations such as ordinals, runes, and fractional Bitcoin assets. These tools open new frontiers for developers looking to build on the world’s most secure and decentralized blockchain.
By integrating advanced indexing and transaction capabilities, OKX OS enables builders to create novel use cases like:
- Rune-based token launchpads
- Ordinal inscription marketplaces
- Bitcoin-native gaming assets
This positions OKX OS as one of the few development platforms actively supporting the evolving Bitcoin ecosystem beyond simple transfers.
Industry-Leading Security & Scalability
Security is embedded into every layer of OKX OS. Leveraging OKX’s proven security infrastructure—including audited smart contracts and battle-tested key management systems—developers can build with confidence.
Additionally, the platform has already demonstrated its scalability by serving millions of users and processing hundreds of millions of API requests daily. Projects like Tomo Wallet, Zerion, Blade of God, Gravity, and DuckChain are already using OKX OS to power their applications.
Core Components of OKX OS
Wallet API
A single API endpoint simplifies multi-chain wallet creation, balance tracking, transaction history retrieval, and signing operations across all supported chains. This dramatically reduces integration time for wallet developers or apps requiring embedded wallet functionality.
Liquidity Access
Developers gain access to cross-chain swaps and deep liquidity across 20 major networks, integrated with over 500 decentralized exchanges. This allows for optimized trade routing and lower slippage in DeFi applications.

NFT Market Tools
From real-time pricing data to marketplace aggregation, OKX OS provides everything needed to build rich NFT experiences. Developers can integrate minting dashboards, portfolio viewers, and auction engines with minimal effort.
On-Chain Data API
Covering over 50 blockchains, this robust data layer delivers actionable insights—from token holdings and transaction patterns to contract interactions. With open APIs designed for easy integration, it's ideal for analytics platforms, portfolio trackers, and AI-driven dApps.
Game Development Suite
Tailored for Web3 gaming, OKX OS offers solutions for wallet onboarding, in-game asset management, and player growth tools—all optimized for over 100 popular chains. Game studios can now focus on gameplay instead of blockchain plumbing.
Accelerating Web3 Innovation
OKX is not stopping at infrastructure. In the coming months, the company plans to launch a global developer support program, including in-person meetups, hackathons, and grants to fuel innovation within the OKX OS ecosystem.
These initiatives aim to foster a vibrant community where developers can collaborate, learn, and push the boundaries of what’s possible in decentralized technology.
