Abstract: A facility for proxying NFT is described. The facility intercepts a request directed to a user to prove possession of a particular NFT. In response to this intercepting, the facility determined that the NFT is a shared NFT, and that the user is among a group of users entitled to use the shared NFT. In response to this determining, the facility automatically uses information available by virtue of possession of the shared NFT to satisfy the intercepted request on behalf of the distinguished user.
