Investing in a buy-back option allows you to purchase artworks at 50% of their market value for a specific time period. You can earn an expected return of at least 4% per year. If the seller does not execute their buy-back within the allotted time, ownership of the artwork remains with you, unlocking limitless potential for future gains. Arkefi provides a secure custody solution for physical artworks and creates authenticated digital representations on the blockchain, which is then divided into smaller units that can be easily bought and sold by investors. The artworks are held in custody on behalf of the seller and buyer in bonded warehouses located in Switzerland.
