Crypto Exchange OKX's Polygon-Powered Layer 2, 'X Layer,' Hits Public Mainnet

OKX, the fourth-largest crypto exchange, said its new layer-2 blockchain, called X Layer, has gone live on its public mainnet, a continuation in the era of major crypto companies starting their own distributed networks. X Layer, previously known as X1, makes use of Polygon's Chain Development Kit (CDK), a customizable toolkit that lets developers build their own chains by making use of zero-knowledge technology. The news comes as other major cryptocurrency exchanges have pursued their own layer-2 networks over the past year. In a press release, OKX said its developers will be contributing to CDK’s codebase, and that X Layer will connect to Polygon’s wider ecosystem via the AggLayer.
