ExRelay is a side-chain, relay matching node network designed to facilitate asset settlement and trading on Ethereum. It transfers intricate computational tasks to a side-chain, drastically reducing gas fees and easing the load on Ethereum's main chain. ExRelay allows instant order placement, cancellation, and asset matching without the need for deposits or withdrawals. All assets are mapped accurately, ensuring seamless operation while maintaining full decentralization.

ExRelay offers significant benefits including reduced gas fees by utilizing a side-chain for computations, alleviating the stress on the main Ethereum chain. It supports instant transactions with no minimum deposits, withdrawals, or asset locking requirements, facilitating efficient and hassle-free trading. The platform enhances asset security with extra pre-verification mechanisms like the Thunder network, ensuring robust risk management for small transactions.

Unlike other Ethereum layer solutions, ExRelay specifically focuses on asset settlement and trading optimization. By offloading computational tasks to a relay matching node network, it significantly reduces gas expenses compared to relying solely on Ethereum's main chain. ExRelay’s infrastructure ensures complete decentralization and provides comprehensive verification processes, setting it apart as an ideal solution for decentralized applications (DApps) needing enhanced speed and security.

As an infrastructure technology, ExRelay is crucial for the development and realization of decentralized applications (DApps) on Ethereum. By leveraging side-chain computations, it enables more efficient asset settlement processes, aligning with the Ethereum 2.0 advancements. ExRelay ensures scalability and efficiency, offering a robust platform for DApps to build and operate without compromising on the core decentralized principles of the Ethereum ecosystem.

To integrate ExRelay with an existing Ethereum DApp, developers should ensure compatibility with the ExRelay network, which acts as a layer-2 solution. The primary step involves configuring the DApp to interact with the side-chain for computation offloading, enabling instant order placements and cancellations. Integration should focus on utilizing the ExRelay’s infrastructure for asset mapping and matching processes, while adhering to its robust security verification mechanisms.

If issues occur when using ExRelay, verify that all configurations align with the latest ExRelay specifications for seamless side-chain operations. Ensure network connectivity is stable and that Ethereum’s main net is operational for transaction confirmations. It's crucial to check integration settings for the DApp involved and confirm that the ExRelay infrastructure is correctly implemented to avoid disruptions. For asset-related discrepancies, review pre-verification protocols, particularly with the Thunder network integration.
