I started with the base game cinder block static object and added the chains from the Exposed Prostitute Outfit.

It can be found in the basement of the Lucky 38, during Mr. House's Securitron demonstration (Mr. House totally strikes me as the kind of person who'd be into a dodgy, unregulated, decentralized currency that the government can't track or tax).
