FFirin

Set up your identity

Three steps to establish a verified, self-sovereign identity on Firin. No email, no institutional account.

  1. 1. Connect your wallet

    Your Solana wallet is your identity on Firin. No seed phrase is ever transmitted — all signing happens locally in your wallet.

  2. 2. Sign in with Solana (SIWS)

    Sign a canonical challenge message to prove wallet ownership. Issues a 24-hour JWT. No password, no email, no third-party auth provider.

  3. 3. Proof of Personhood

    A one-time selfie confirms you're a unique human. A biometric fingerprint is stored — never the photo. Your uniqueness attestation is written to the Solana Attestation Service. Valid for 7 days.
