OKX, a leading crypto exchange and Web3 ecosystem, is launching an Ethereum-based ZK L2 network built with Polygon CDK (Polygon Chain Development Kit), the open-source toolkit that makes it easy to build sovereign Ethereum L2s

__Introducing **X1**__
X1 will be a secure, highly performant platform for building dApps. Connect to the testnet for X1 today! 🌐

Why is X1 beneficial for users, developers and projects?

🤝 Harmonized Liquidity

In the future, Polygon CDK-built chains will be interoperable (atomic, near-instant cross-chain transactions), making access to liquidity a problem of the past. This means devs can focus on use-case, not user acquisition. X1, with gas fees paid in OKB, OKX’s native token, is connecting OKX’s 50 million+ community to the wider Polygon & Ethereum ecosystem. OKX users will be able to tap Ethereum and soon other CDK chain liquidity <:polygon_circle:1095500518547263551>

👷 OKX as a Core Contributor to Polygon CDK

In building X1, OKX joins NEAR Protocol and other protocol developers in becoming a core contributor key contributor to the Polygon CDK, committing engineering resources to help add configs and tools for future chains. Ethereum devs will have a decentralized protocol for building primitives previously unfeasible on OKX, from DeFi to social and everything in between

🔐 Security

Deploying the next big dApp on X1 is secure and seamless because Polygon CDK–built chains are secured by ZK proofs and bytecode-compatible with the EVM 💻

Polygon CDK keeps picking up serious contributors. Curious how X1's interoperability with other CDK chains will work in practice.
