Rosetta API is an open standard designed to simplify blockchain deployment and interaction. The Rosetta API specifications offer a common interface to communicate with blockchains of different types. Because each blockchain has its own mechanism for signing transactions, forming requests, querying balances, and other operations, wallets and exchanges like Coinbase are constantly developing and maintaining the software required for interacting with these technologies. Rosetta is an ecosystem allowing everyone to easily integrate and interact with all supported blockchains.
The support for the Electra Protocol network was added to Rosetta in September 2021 (see roadmap).
