A portable, self‑custodial 2FA layer for Cardano, supporting TOTP, WebAuthn, and Google login for easy onboarding. We are actively researching ZK techniques for future decentralization & anonymity — not implemented in this phase.
End‑to‑end security loop that preserves self‑custody and works with existing Cardano wallets & dApps.
Off‑chain conditional co‑signer (closed‑source, auditable)
On‑chain smart contracts (open‑source)
Browser extension
Onboard with a Cardano wallet and add a second factor. No dApp or wallet changes required.
Use Google Authenticator, Authy, 1Password, etc.
Hardware keys, biometrics
OAuth‑based co‑signing
Under research, not available
Asset Vault contract (Aiken)

Sign with your existing Cardano wallet
Signature 1/2 ✓
Enter TOTP / use WebAuthn / Google
Only upon successful 2FA
Signature 2/2 ✓
Transaction complete

Amount:
100 ADA
Status:
ConfirmedMultiple layers of protection without compromising user sovereignty.
Time‑locked emergency withdrawal if the co‑signer becomes unavailable.
Change the Identity Vault address with proper authorization.
Identity Vault never holds private keys or assets — only conditional signatures.
Smart contracts, SDKs, and API specs will be open‑sourced. Backend is closed‑source but auditable.
Cardano‑first MVP, multi‑auth expansion, and ZK research — not ZK implementation.
Testnet Asset Vault + TOTP + Extension interception + Landing page
WebAuthn, Google login, Dashboard MVP
Google‑auth‑derived wallet (with Asset Vault) + protocol spec + advanced dashboard
Security audit • Mainnet release (contracts/SDKs/specs) • ZK research document
Final report & video
Note: Zero‑knowledge proofs and threshold signatures are exploratory research in this proposal and are not part of the implemented MVP.
