The blockchain ecosystem continues to evolve at a rapid pace, and one of the most significant developments in 2024 is the launch of X Layer, OKX’s new Layer 2 (L2) network. Announced on April 16, 2024, X Layer marks a bold step by the global crypto exchange to expand its footprint in the decentralized world. Built on Ethereum and powered by zero-knowledge (ZK) technology, X Layer is designed to enhance scalability, reduce transaction costs, and deepen integration across OKX’s ecosystem—including the OKX Exchange and OKX Web3 Wallet.
With major players like Coinbase already making waves through their Base network, the question arises: Can X Layer effectively compete with established L2s? This article explores the technical foundation, strategic vision, ecosystem momentum, and market dynamics shaping X Layer’s journey.
What Is X Layer and How Does It Work?
X Layer leverages Polygon’s Chain Development Kit (CDK), a modular framework that enables fast, secure, and customizable rollup deployments. By building on Ethereum and utilizing ZK-rollup technology, X Layer ensures high throughput while maintaining the security guarantees of the Ethereum mainnet. This combination allows for near-instant transactions at a fraction of the cost—critical for mass adoption.
One of the defining features of X Layer is its seamless integration with OKX’s existing infrastructure. Users can move assets between the centralized exchange and the L2 network with minimal friction, bridging the gap between CeFi and DeFi experiences. The network also supports native gas payments in OKB, OKX’s utility token, further incentivizing platform engagement.

Strategic Vision: Building the Web3 Highway
Haider Rafique, Chief Marketing Officer at OKX, articulated a compelling long-term vision for X Layer:
“We envision X Layer and other Layer-2 chains as the highway infrastructure of the Web3 world, with dApps as the marketplaces and self-hosted wallets as the vehicles that take you there.”
This analogy underscores a broader ambition: positioning X Layer not just as a scaling solution, but as foundational infrastructure for next-generation decentralized applications. With over 50 million users already in the OKX ecosystem, the potential for rapid onboarding is immense.
During its testnet phase, OKX successfully attracted more than 200 decentralized applications (dApps). The current ecosystem includes:
- ~40 DeFi protocols
- 20 infrastructure projects
- 12 cross-chain bridges
- 5 growth and analytics tools
- 16 wallet integrations
- 10 NFT and gaming platforms
- 10 SocialFi applications
- Multiple developer tooling solutions
Notable early adopters include Curve, QuickSwap, and LayerZero, all of which are enhancing liquidity and interoperability across chains. The presence of such high-profile dApps signals strong developer confidence in X Layer’s technical robustness and user reach.
Ecosystem Momentum vs. Market Competition
The timing of X Layer’s launch places it in direct competition with rapidly growing L2 networks—most notably Base, Coinbase’s Ethereum L2. Base achieved remarkable traction post-launch, recording a 70% increase in Total Value Locked (TVL) within a single week. According to L2Beat data, Base currently ranks third in TVL with $5.29 billion, capturing 14.17% of the L2 market share—trailing only Arbitrum One and Optimism.
| Network | TVL (Approx.) | Market Rank |
|---|---|---|
| Arbitrum One | $7.8B | #1 |
| Optimism | $5.6B | #2 |
| Base | $5.29B | #3 |
Note: Table included for illustrative context only; not part of final output.
While exact TVL figures for X Layer are still emerging, its integration with OKX’s massive user base provides a unique advantage. Unlike purely community-driven launches, X Layer benefits from immediate access to millions of active traders and investors—a ready-made audience for DeFi, NFTs, and Web3 gaming.

Frequently Asked Questions (FAQ)
Q: What blockchain is X Layer built on?
A: X Layer is built on Ethereum using zero-knowledge (ZK) rollup technology, ensuring security, scalability, and compatibility with existing Ethereum tools and wallets.
Q: Can I use OKB to pay gas fees on X Layer?
A: Yes. OKB, the native token of OKX, serves as the primary gas token on X Layer, offering users cost savings and utility incentives.
Q: How does X Layer differ from Base or Arbitrum?
A: While all three are Ethereum L2s, X Layer stands out due to its deep integration with a major exchange ecosystem. This enables smoother asset bridging and faster user onboarding compared to more decentralized alternatives.
Q: Is X Layer open to all developers?
A: Absolutely. X Layer is permissionless and welcomes developers to deploy dApps, build tools, and contribute to the growing ecosystem.
Q: Does X Layer use optimistic or ZK-rollup technology?
A: X Layer uses ZK-rollup technology via Polygon’s CDK, providing faster finality and stronger security guarantees than optimistic rollups.
Q: How many dApps are live on X Layer?
A: Over 200 dApps were onboarded during testnet, spanning DeFi, NFTs, gaming, SocialFi, wallets, and infrastructure—many now live on mainnet.
Challenges Ahead: Leadership Changes and Trust Building
Despite strong technical and ecosystem momentum, OKX faces challenges beyond technology. The recent departure of key executives—including Tim Byun and Wei Lan—has sparked discussions about organizational stability. While personnel changes are common in fast-moving industries, consistent leadership is crucial for long-term trust in blockchain projects.
Additionally, regulatory scrutiny remains a global concern for centralized exchanges expanding into decentralized infrastructure. For X Layer to succeed, OKX must demonstrate transparency, decentralization progress, and commitment to open standards.
