On April 15, 2024, the cryptocurrency exchange OKX unveiled its latest innovation in blockchain technology: the X Layer. This second-layer solution is designed specifically for Ethereum, aiming to reduce transaction fees and improve application compatibility within the network.

Partnership with Polygon Labs and Introduction of the X Layer (X1) Protocol

OKX has launched the X Layer in collaboration with the team at Polygon Labs, according to a press release referenced by Cointelegraph. The newly introduced X Layer (X1) protocol utilizes zero-knowledge proof technology to ensure lower fees for Ethereum network transactions and enhanced compatibility for users interacting with decentralized applications (dApps).

Full Compatibility with Ethereum Virtual Machine

The press release highlights that X Layer is fully compatible with the Ethereum Virtual Machine (EVM), allowing developers to create and deploy decentralized applications on the Ethereum base without the need to rewrite any underlying code. This feature is significant as it facilitates the seamless integration of new applications into the Ethereum ecosystem, promoting greater development and innovation.

Strategic Importance of Second-Layer Solutions

Haider Rafique, the Chief Marketing Officer at OKX, emphasized the critical role of second-layer networks like X Layer in the evolution of Web3 infrastructure. "We are building an ecosystem that maximizes coherence and compatibility. We believe that X Layer holds boundless potential thanks to its strong community and its connectivity with other Ethereum-based networks," Rafique stated.

Beta Version and dApp Integration

OKX had previously introduced a beta version of X Layer in November 2023. This initiative led to the launch of over 50 dApps, including applications from projects such as Graph, Curve, LayerZero, QuickSwap, Galaxy, and Timeswap. This development has been instrumental in demonstrating the robustness and utility of the X Layer as a platform for fostering extensive dApp growth.

Enhancements for OKX Users

The implementation of the proprietary L2 protocol enables OKX users to transfer assets and perform cryptocurrency deposits and withdrawals more efficiently. Moreover, it provides access to nearly 200 dApps offering a variety of services such as token exchanges, staking, and various smart contract functions.

Use of OKX Platform Token

The company also specified that the OKX platform token would be utilized to pay for transaction fees on the L2 network, integrating the tokenomics of the exchange with the operational aspects of the X Layer, thereby enhancing the utility of its native token.

Market Potential and Future Prospects

Experts from VanEck have projected a significant growth in the market capitalization of L2 solutions within the Ethereum network, estimating it could reach $1 trillion by 2030. This forecast underscores the expanding role and importance of second-layer solutions in enhancing blockchain scalability and efficiency.

Industry Developments

In related developments, another major cryptocurrency exchange, Coinbase, launched its own second-layer network called Base for Ethereum in August 2023. This move by Coinbase, similar to OKX's initiative, reflects a broader industry trend towards the adoption of L2 solutions to address the challenges of scalability and high transaction costs in the blockchain space.


OKX's launch of the X Layer marks a significant milestone in the advancement of blockchain technology, particularly in enhancing the Ethereum network's functionality and efficiency. By reducing costs and improving dApp compatibility, the X Layer stands poised to play a pivotal role in the future of the Web3 infrastructure, supporting a more integrated and expansive digital ecosystem.
