The cryptocurrency landscape continues to evolve rapidly, with major exchanges expanding beyond trading platforms into blockchain infrastructure. OKX, one of the world’s leading digital asset exchanges, has announced the development of its own Layer 2 (L2) blockchain named X1, built using Polygon’s Chain Development Kit (CDK). This strategic move positions OKX at the forefront of Web3 innovation, enabling scalable, low-cost transactions while deepening user engagement in decentralized ecosystems.
Expected to launch in the first quarter of 2024, X1 leverages zero-knowledge (ZK) rollup technology, a cutting-edge cryptographic method that enhances transaction efficiency and security on the Ethereum network. As scalability remains a key bottleneck for mass blockchain adoption, ZK-powered Layer 2 solutions have emerged as a dominant trend in 2025—offering faster processing speeds and reduced fees without compromising decentralization.

Strategic Integration of OKB as Native Gas Token
A core feature of the X1 network is the integration of OKX’s native token, OKB, as the primary currency for gas fees. This marks a significant expansion of OKB’s utility beyond exchange-based benefits like fee discounts and token sales access. By embedding OKB into the operational layer of a live blockchain, OKX strengthens its tokenomics and incentivizes broader on-chain usage.
This development aligns with a growing trend among centralized exchanges to launch their own Layer 2 solutions—effectively bridging the gap between traditional crypto trading and decentralized application (dApp) ecosystems. With OKB now powering transactions on X1, users gain a seamless pathway from asset management to active participation in Web3 applications such as DeFi, NFTs, and social protocols.
Industry-Wide Shift Toward Exchange-Led Blockchains
OKX is not alone in this endeavor. The past year has seen a surge in exchange-driven blockchain initiatives:
- Coinbase launched Base, its Ethereum Layer 2 network built on the Optimism OP Stack, positioning itself as a hub for consumer-focused dApps.
- Kraken is reportedly exploring its own Layer 2 solution, with Polygon’s CDK among the technologies under consideration.
These moves reflect a broader industry shift: crypto exchanges are no longer just gateways to digital assets—they are becoming foundational infrastructure providers in the decentralized web.
Polygon Labs CEO Mark Boiron emphasized the collaborative potential of these efforts. “You can look at all these chains as being competitive, or you can look at them as kind of being one,” he said in an interview with CoinDesk. “I fundamentally believe that if we can have the biggest ecosystem of chains that are all interoperable, then everyone that is part of that ecosystem is going to win.”
This vision underscores the importance of interoperability—the ability for different blockchains to communicate and share data seamlessly. By building X1 on Polygon’s modular framework, OKX ensures compatibility with other CDK-based chains, fostering cross-chain collaboration and liquidity sharing.
Empowering Developers and Advancing Web3 Adoption
For developers, X1 presents a compelling opportunity. Designed with scalability and accessibility in mind, the network aims to lower barriers to entry for building high-performance Web3 applications. Jason Lau, Chief Innovation Officer at OKX, highlighted this goal in a press release:
"X1 will be a key pillar of our efforts to educate and bring our users on-chain and into the world of Web3. This scalable and accessible network is perfect for developers, who can build on X1 to deliver user-friendly, world-class consumer Web3 applications, all while maintaining interoperability with other networks and ecosystems."
With robust tooling, developer incentives, and access to OKX’s global user base, X1 could become a launchpad for innovative dApps targeting real-world use cases—from decentralized identity and gaming to financial inclusion and content monetization.

Frequently Asked Questions (FAQ)
What is X1 by OKX?
X1 is a Layer 2 blockchain developed by OKX using Polygon’s Chain Development Kit (CDK). It leverages zero-knowledge rollup technology to provide fast, low-cost transactions on Ethereum while supporting scalable Web3 applications.
When will X1 go live?
The X1 network is expected to launch in the first quarter of 2024. Official updates will likely be shared through OKX’s official channels closer to release.
Can I use OKB to pay gas fees on X1?
Yes. OKB will serve as the native gas token on the X1 network, expanding its utility beyond the OKX exchange platform.
How does X1 compare to other exchange-led blockchains like Base?
Like Coinbase’s Base, X1 is an Ethereum Layer 2 focused on scalability and developer growth. However, X1 uses Polygon’s CDK with ZK technology, whereas Base is built on the Optimism OP Stack using optimistic rollups.
Is X1 part of the Polygon ecosystem?
While built using Polygon’s CDK, X1 operates as an independent chain. However, it benefits from interoperability with other CDK-based networks and shares technical foundations with the broader Polygon ecosystem.
Will OKX engineers contribute to Polygon CDK development?
Yes. As part of the collaboration, OKX engineers will become core contributors to the Polygon CDK open-source project, helping shape its future evolution.

Final Thoughts: A New Era for Exchange-Backed Blockchains
The launch of X1 represents more than just a technical upgrade—it signals a strategic pivot toward user empowerment and long-term ecosystem development. By combining Polygon’s proven infrastructure with OKX’s vast user base and technological expertise, X1 has the potential to accelerate mainstream adoption of Web3 technologies.
As exchanges increasingly take on roles traditionally held by protocol developers and venture funds, the line between centralized platforms and decentralized networks continues to blur. In this new paradigm, projects like X1 may well define the future of digital ownership, financial sovereignty, and internet-native economies.
With interoperability at its core and developer experience at the forefront, X1 isn’t just another blockchain—it’s a bridge to a more connected, inclusive, and scalable Web3 world.
