The fourth-largest cryptocurrency exchange, OKX, announced that the public mainnet of its new layer-2 blockchain, dubbed X Layer, has gone live. This is an extension of the trend where big cryptocurrency companies have started their own distributed networks.

X Layer, formerly known as X1, leverages Polygon’s Chain Development Kit (CDK), an adaptable toolkit that enables developers to use zero-knowledge technology to create their own chains.

The announcement coincides with the pursuit of layer-2 networks by other significant cryptocurrency exchanges over the past 12 months. Optimism’s OP Stack is the foundation of Coinbase’s “Base” blockchain, which was introduced in August. It has been reported that Kraken is considering developing its own layer-2 blockchain.


According to a press release from OKX, X Layer will be connected to Polygon’s larger ecosystem through the AggLayer, and its developers will be contributing to the CDK’s codebase. AggLayer is a Polygon product designed to combine liquidity from different chains that have been spun up with the help of the project’s technology.

According to Polygon Labs Chief Executive Officer Mark Boiron, “OKX’s 50 million users now have an easy path to onboarding to X Layer and all the other chains connected to the AggLayer.”


Users of X Layer, which went live on the testnet in November, will have access to more than 170 decentralized apps (dapps), with more scheduled to launch shortly.

According to the press release, OKX Chief Marketing Officer Haider Rafique stated, “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.”CRYPTOCASTER® - DECENTRALIZED FREEDOM!

We hope you appreciated this article. Before you move on, I was hoping you would consider taking the step of supporting CryptoCaster’s journalism. 

From  Elon Musk, Larry Fink(BlackRock) to Jamie Dimon(JP Morgan Chase) a number of billionaire owners have a powerful hold on so much of the hidden agendas’ which eludes the public concerning the paradigm shift juxtaposed by cryptocurrency and web3 emerging technologies. CryptoCaster is different. We have no billionaire owner or shareholders to consider. Our journalistic efforts are produced to serve the public interest in crypto development and institutional disruptions – not profit motives.

And we avoid the trap that befalls much U.S. and global media – the tendency, born of a desire to please all sides, to engage in false equivalence in the name of neutrality and retail consumer protection. While fairness and transparency dictates everything we do, we know there is a right and a wrong position in the fight against fiat global banking interest and monetary reconstruction precipitated by the emerging crypto ecology.

When we report on issues like the FTX, Binance and Ripple crisis, we’re not afraid to name who or what is uncovered. And as a crypto sentinel, we’re able to provide a fresh, outsider perspective on the global monetary disruption – one so often missing from the insular American and European media bubble. 

Around the world, readers can access the CryptoCaster’s paywall-free journalism because of our unique reader-supported model. That’s because of people like you. Our readers keep us independent, beholden to no outside influence and accessible to everyone – whether they can afford to pay for news and information, or not.

We thankyou for the on-going support our readers have bestowed monetarily.
