Ownership transfer
Time-limited transfer codes hand over ownership securely.
Solution
Verified person-to-person ownership transfer with an immutable HMAC-signed chain of custody.
Second-hand and gifting markets need provable provenance. Junction records every transfer in a tamper-proof history, so a buyer can verify the chain of custody from the first owner onward.
Time-limited transfer codes hand over ownership securely.
Every transfer is appended to an HMAC-signed ledger.
Buyers verify provenance before they pay.
How it works
Generate a time-limited transfer code and share it.
Scan or enter the code to accept ownership.
The new owner is appended to the immutable history.
