Stackr Network, a startup that is developing an SDK for building application-specific rollups (ASRPs), has raised $2.5 million in funding. This funding round was led by Framework Ventures and included participation from other notable investors, such as Coinbase Ventures, Polygon Studios, and Fabric Ventures. ASRPs are a new type of rollup that is specifically designed to scale individual applications. This is in contrast to general-purpose rollups, such as Optimism and Arbitrum, which are designed to scale the entire Ethereum network. Stackr Network's SDK is designed to make it easy for developers to build and deploy ASRPs. The SDK provides developers with all the tools they need to create a custom rollup for their application, including a sequencer, a state machine, and a bridge.
