A TypeScript library implementing Sign-In with Ethereum (EIP-4361), a standard message format for Ethereum accounts to authenticate with off-chain services via message signing. It provides a self-custodied alternative to centralized identity providers for establishing web sessions.
Use cases
- authenticate users with ethereum wallets instead of passwords
- implement sign-in with ethereum in a web app
- create cookie-based sessions from wallet signatures
- replace centralized identity providers with self-custodial login
- verify signed siwe messages on a backend
- add wallet-based login to a dapp
When to choose
- you want passwordless, self-custodial authentication for an Ethereum-based service
- you need standards-compliant EIP-4361 message creation and verification in TypeScript
- you are building a dapp or backend that establishes sessions from wallet signatures
When to avoid
- you need traditional email/password or OAuth-based authentication
- your stack is not JavaScript/TypeScript and you cannot use a JS runtime
- you require a formally audited security-critical implementation
