Global crypto exchange and Web3 innovator OKX has officially launched the X Layer public mainnet, marking a significant milestone in Ethereum Layer 2 scalability. This ZK-powered network leverages Polygon CDK and AggLayer technology to deliver secure, low-cost transactions while enabling seamless interoperability across chains.
What Is X Layer?
X Layer is an EVM-compatible ZK-Rollup built using Polygon's Chain Development Kit (CDK), designed to:
- Reduce gas fees by over 90% compared to Ethereum mainnet
- Process 2,000+ TPS with sub-second finality
- Enable shared liquidity across AggLayer-connected chains
- Support 170+ dApps at launch with native OKX wallet integration
Core Technical Advantages
| Feature | Benefit |
|---|---|
| ZK-Proof Security | Inherits Ethereum-level security with cryptographic verification |
| Polygon CDK Framework | Standardized tooling for rapid dApp deployment |
| AggLayer Integration | Unified liquidity pool across multiple L2 networks |
| EVM Bytecode Compatibility | Zero-code modifications for existing Ethereum dApps |
Why X Layer Matters for Mass Adoption
OKX CMO Haider Rafique explains: "X Layer serves as infrastructure highways for Web3, where dApps become destinations and self-custody wallets act as vehicles. Our 50M+ user base provides instant network effects—developers gain access to one of crypto's largest engaged communities from day one."
Adoption Metrics Since Testnet (Nov 2023)
- 50+ dApps deployed within first week (The Graph, Curve, LayerZero, etc.)
- $220B+ in OKX platform assets available for bridging
- OKB token as native gas currency with fee stabilization mechanisms
- 5000+ transactions per hour during stress tests
Ecosystem Growth Potential
X Layer's architecture enables unique synergies:
- Polygon Partnership
Joint contributions to CDK development ensure ongoing technical innovation - AggLayer Connectivity
Cross-chain swaps with near-instant finality via shared state proofs - OKX Wallet Integration
One-click access for 50M+ users across 90+ supported chains
Polygon CEO Marc Boiron notes: "This collaboration solves liquidity fragmentation—OKX users can seamlessly interact with any AggLayer chain while developers tap into exponential network growth."
FAQ: X Layer Essentials
What makes X Layer different from other L2s?
X Layer combines ZK-rollup security with Polygon CDK's standardized tooling and OKX's massive user base—creating a uniquely positioned "ready-to-scale" ecosystem.
How do developers deploy on X Layer?
Ethereum developers can migrate dApps without code changes due to full EVM equivalence. New projects can use Polygon CDK's pre-audited templates.
What's OKB's role in the network?
OKX's platform token serves as:
- Gas fee payment currency (with discounted rates for OKB holders)
- Governance token for future protocol upgrades
- Staking asset for sequencer nodes
When will withdrawals be enabled?
Withdrawals to Ethereum mainnet follow standard ZK-proof generation intervals (~30 min), with instant exits available via AggLayer liquidity pools.
