Sign-In with Ethereum (EIP-4361) seeks create a specification that includes both elements of signing and identity to enable users to control their digital identity with their Ethereum account and ENS profile instead of relying on a traditional intermediary.

Spruce has added Polygon support in its identity infrastructure that enables Polygon developers to have standard and interoperable ways to issue, verify, and store trusted information to allow any Polygon account to control their identity.

We are creating a collaborative environment for our work on Sign-in With Ethereum, and encourage community participation and feedback as we create the specification and reference implementation.

The initial goal for the Sign-in With Ethereum efforts is to create a specification and reference implementation for an end-to-end authentication flow for Ethereum accounts to log in to traditional Web2 services, using ENS as a primary user-controlled data aggregator.

Sign-in with Ethereum will allow users to use their Ethereum accounts to access web services instead of accounts owned by large corporations.

At Spruce, we’re building the most convenient developer tools to let users control their data across all digital interactions.
