Hanko Seal

A seal for a physical work of art.

A Hanko is a chip under wax on the back of a work, linked to a public record. Scan the seal with a phone and you see who made the work, who holds it now, and every sale since.

For collectors

Scan the seal. See the record.

The record sits on a public blockchain, so no one can quietly change it. A work moves to a new holder only when its own seal is scanned. You can buy by card, without a crypto wallet or an exchange.

For artists

Your own market, your own royalty.

Each artist gets their own record, market and court. You set the price and the royalty, and the royalty is paid to you on every resale. Hanko Seal never holds your money, and the record keeps working without anyone from Hanko Seal present.

For marketplaces

One public list, one written standard.

Every Hanko record is listed in one public registry, with a written standard for how to read a work and how to sell it. A marketplace can show these works today and sell them under rules the artist sets.

Status. Hanko Seal is being built. Everything runs on a test network today, and no real money moves.
