iconic buildings, the Xapo Bank, will be converted into an incredible immersive viewing experience
showcasing the most exciting and collectable NFT art in the world.

barracks in Gibraltar’s old town in the shadow of the famous rock, will house a unique collection of artworks
from a carefully chosen selection of leading crypto artists.

The striking investment and collection pieces will be presented for sale on extra-large, high tech NFT
screens specifically designed by Tokenframe, the official NFT Display Partner for Crypto Art Island and the
first company to offer NFT ownership authentication devices linked to the users’ Web3 wallets.

fully-fledged platform secured by WISeKey technology ensuring an authenticated and signed version of
the actual digital asset, providing proof of ownership, provenance and a set of smart contracts Terms &
