However, there is a significant user base, including Android and enterprise users, who are developing on JVM platforms and find it challenging to leverage the capabilities of the Arbitrum network due to the lack of native support. \nTo address this gap, we plan to integrate support for client-side interactions with Arbitrum into Web3j. We will incorporate functionalities for L2 networks like handling of L2 transaction receipts, interactions with Arbitrum-specific data entities and utility functions. These features will empower developers to fully utilize the capabilities of L2 solutions directly from Java-based applications, promoting a more versatile and robust development environment.\n", "hidden": false, "question": "Please describe the developer tool or library you're working on.
