Self.ID is a Ceramic-based decentralized identity framework providing SDK packages and REST-compatible APIs for managing DID profiles, verifiable credentials, and self-sovereign identity data on the Ceramic network. It supports Ethereum-based authentication via 3ID Connect and enables reading and writing identity records such as basic profiles, linked crypto accounts, and linked Web2 accounts. The SDK is organized in layered packages (core, web, react, framework) targeting both Node.js and browser environments.
