Caldera, a platform that enables developers to quickly create layer-2 blockchains, has raised $15 million in a Series A funding round led by Founders Fund, Peter Thiel's investment firm. The funds will be used to expand Caldera's team and build out the Metalayer, an interoperability ecosystem that simplifies the process of launching applications across multiple blockchains. Caldera currently offers a user-friendly interface for launching layer-2 "rollup" chains that record data to Ethereum, with the ability to select a rollup ecosystem and customize components to fit specific use cases.
