CustID

about

description

CustID is a mobile identity vault built on Nostr and the SISTR protocol. Governments everywhere are rolling out national e-ID — the EUDI Wallet across the EU, Switzerland's e-ID, and more. Those wallets can work well, yet your recognized identity is still issued, attested and revocable by an authority. CustID flips that: your identity simply IS your key, held on your device, and no one can take it from you. One app to hold your identities, memberships, badges and passes. Offline, without Google. - Identity vault: multiple identities, keys protected by the hardware-backed Android Keystore, never held in plaintext during normal operation; moving or backing up an identity only ever exports an encrypted ncryptsec, never a raw key. - Nostr signer (NIP-46 bunker): sign for any NIP-46 compatible client remotely; your key never leaves your device. - Local Android signer (NIP-55): Nostr apps installed on the same device, such as Amethyst, can ask CustID to sign, encrypt and decrypt without relays. Remembered permissions can answer in the background depending on the identity's security settings and Android's background policies; anything else asks you first. - NFC challenge-response: answer access-control challenges with a tap (doors, gates, event ticketing, ...). - Zero-knowledge proofs: planned in the SISTR project, for privacy-preserving identity claims. - QR code proofs: scan or present signed proofs as an NFC fallback. - No Google: no Firebase Cloud Messaging for notifications, no Google Play Services. Distributed via Zapstore only. **Requires Android 14 (API 34)** or newer; older Android versions are not supported. 👷 This is a public beta. ⚠ Please backup your keys and don't use CustID for critical applications until a stable release is published.
