PANews reported on November 14 that Caldera, a Web3 infrastructure platform backed by Founders Fund, has acquired the Hook team to jointly build Metalayer, an Ethereum Rollup infrastructure platform. The acquisition amount was not disclosed, following Caldera's $15 million Series A financing in July . The Hook Odyssey protocol originally developed by the Hook team focused on the perpetual futures market for Meme coins and NFTs, and was built on the Arbitrum Orbit framework, but the protocol has been shut down so that the team can focus on the development of Metalayer.

Caldera is a Rollup-as-a-Service platform that has assisted more than 50 projects in creating application-specific chains, including Manta Pacific, Injective, and ApeChain. The Metalayer platform aims to optimize the development experience of multiple Rollup applications and strengthen the collaboration between the Optimistic and ZK Rollup frameworks to unify the Ethereum expansion ecosystem.
