MPC Threshold Signature
Splits a single <a href="https://crypto-bible.com/en/glossary/wallet-and-security/private-key/" target="_blank" rel="noopener">Private Key</a> into multiple shares held across different devices or parties, so signing a transaction only requires a set threshold of shares to collaborate — the complete key is never assembled anywhere at any point, from creation through signing.

Passkey Authentication
Replaces passwords with a fingerprint, face scan, or your device's own security mechanism. After your device verifies locally that it's really you, it cryptographically generates a proof tied to that specific login or approval — the verification never leaves the device or gets transmitted anywhere, which is exactly why it can't be phished away or stolen in a server breach.

Scoped Consent Credential
A credential authorized only for "this one time, this specific counterparty, this spending cap" — letting a user avoid handing an agent long-lived, unlimited-use full account authority. Instead, a temporary, tightly scoped, single-use authorization gets issued each time, turning "what the user agreed to" into a verifiable, non-repudiable record.
