Spire launches Pylon coordinator to achieve cross chain synchronization composability based on application chains According to Foresight News, Spire Labs has released an article on X stating that its Pylon coordinator can run multiple chain nodes within the synchronization zone, including the underlying L2 and application chain. Pylon can intercept transactions and detect cross chain calls. This release now supports synchronous reading in production environments, and future versions will support synchronous writing, making cross chain applications almost indistinguishable from single chain applications. Spire stated that application chains are suitable for projects that aim to achieve customization, scalability, and sovereignty through independent chains, while also maintaining composability with large generic chains in terms of liquidity, distribution, and infrastructure. At present, this solution has received feedback and support from projects such as Base, ZKsync, Celo, AltLayer, Caldera, etc.
