How it works

More documentation than Christie’s delivers.

A collector who wins a Gives lot receives more documentation than most primary sales at the world’s leading auction houses. The COA is sealed. The chain is permanent. The ANIMUS is living.

Lot mechanics

Six things that travel with every lot.

SENTYAL Provenance Chain record
Every transaction permanently recorded on the chain — append-only, cryptographically anchored, auditable by any party with legitimate interest. The record outlives the lot, the auction, and the gallery.
Certificate of Authenticity
Sealed. Signed by the gallery directors. Includes the artist statement on why this work was donated and what the cause means to them. Travels with the lot for life.
Tax receipt for the charitable portion
30% of the winning bid is the charitable portion. Tax receipt generated automatically within 24 hours of lot close. Accurate. Immediate. No manual process required.
ANIMUS Identity Card
Self-sealing identity card with steganographic fingerprint. Living entity at a permanent public URL. The collector’s record of participation, never separable from the lot.
Artist statement
Why the artist donated this work. What the cause means to them. Travels permanently with the lot record. The collector knows the intention behind their acquisition.
Anti-snipe protection
Real-time bidding. Countdown formats. Anti-sniping built in — any bid in the final two minutes extends the auction. The winning bid is earned, not stolen.
Patent connection

Every record is documented prior art.

Each Gives lot record contributes to the documented prior art for the SENTYAL non-provisional patent filing due April 15, 2027. The system proves itself by operating — not by theory, but by transactions, on the chain, in real time.
