ChainCatcher news, according to Cointelegraph, Avail co-founder Anurag Arjun stated that the current majority of chain abstraction technologies make the crypto ecosystem more fragmented, as each different blockchain base layer has its own set of security assumptions, which makes interoperability between chains challenging.Arjun explained, "They have their own set of validators and cryptoeconomic security. Therefore, you have to create infrastructure called light clients, such as bi-directional light clients. This is often the main bottleneck."He added that bridging between chains is often a multi-step process for communication between blockchain networks, which comes with high costs and security risks, while isolating users and capital into fragmented pools.

ChainCatcher news, according to official sources, the ZK-driven interoperability protocol Union has announced its integration with the modular General Abstract Layer XION, bringing chain abstraction into the Union ecosystem. This will provide the growing list of connected chains in the Union network with XION's user-friendly features, reducing friction in the web3 user experience.With the integration of XION, all users on Union's connected chains will gain powerful new capabilities along with Union's fast, low-cost, and secure ZK-supported transaction and messaging functionalities.
