Signet 01
A ring that signs.
A sterling-silver instrument containing a secure cryptographic key.
Touch it to a phone to review and approve an exact digital action.
Your decision is signed by the object and recorded as a Seal.
01 / Human Authority
As digital systems become capable of acting for us, who holds authority?
Signet 01 places a deliberate point of human approval between a proposed action and its execution.
The exact request is shown to the holder and signed when the ring is touched to the phone. The system can verify that decision before it proceeds.

04 / Issuance
Provenance accrues with each interaction.
Each Signet 01 has a unique number and cryptographic identity.
Every Seal, service and change of holder is added to the same record.
Over time, that record becomes the provenance of the object.
