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
