what's Sign-In with Ethereum?
Sign-In with Ethereum (SIWE) is an open standard that enables users to authenticate to web applications using their Ethereum wallet addresses, providing a secure and decentralized alternative to traditional username-password logins. It leverages Ethereum's cryptographic signatures, where users sign a standardized message containing their address, a nonce, and optional statements about their identity or intent. This allows applications to verify ownership without exposing private keys or requiring centralized identity providers. The protocol is chain-agnostic but primarily built for Ethereum and EVM-compatible networks, integrating seamlessly with wallets like MetaMask. Developers implement SIWE via JavaScript libraries, enabling features like social logins, decentralized identity verification, and permissioned access in dApps. Maintained by the Ethereum community, it promotes self-sovereign identity principles, reducing reliance on third-party services while enhancing user privacy and security in the web3 space.
Sign-In with Ethereum integrated as authentication in the new Grails ENS marketplace on mainnet.

Received funding from ENS DAO.
Integrated as authentication method in Grails ENS marketplace, now has 76 integrations including POAP, Snapshot, Superfluid, and Tally.
A team member publicly announces continued commitment to building the project alongside ENS domains and EFP.
