Blockchain project Avail has announced that it has raised $43 million in a Series A round led by Founders Fund, Dragonfly and Cyber Fund. The new round will be used to build Avail's unified layer that combines data availability, aggregation and shared security to enable modular blockchains to scale and interoperate in a permissionless and secure way. Three months ago, Avail, which spun out from Polygon in March 2023, announced that it had raised $27 million in seed funding.
