The upcoming Ethereum layer-2 network, “X1,” has been launched on a testnet by crypto exchange OKX. The network, developed using the Polygon chain development kit (CDK), will utilize zero-knowledge proofs to validate deposits and withdrawals between layers. OKX, the sixth-largest centralized crypto exchange, plans to make its native coin, OKB, the primary currency for gas fees on the network. X1 is expected to be part of the broader Polygon ecosystem and OKX will contribute to the development of the Polygon CDK software. The new network aims to onboard new users to Web3 and provide a scalable and accessible platform for developers to build consumer Web3 applications. OKX is also the creator of OKT Chain, an Ethereum sidechain.
