Consign your number
Hold an Amber number? Put it up for auction. Set your reserve, pick how long the lot runs, and let the room bid. Settle in dollars or crypto — we handle the hammer.

The Amber Exchange is the only place to acquire a number once the primary has sold out. Every lot is a one-of-one — identity in Club Amber, permanent and provably unique. A buyer's premium of 15% applies; the house takes a seller's commission on each hammer. About the numbers →
