Somnium Space, which was originally built around cryptocurrency and the buying and selling of virtual land as NFTs, and which launched its own CUBE token a year later, was removed from Steam sometime after Valve's 2021 decision to ban games from Steam which featured crypto-based economies and NFT commerce. Valve's policies forbidding NFTs and crypto games have not changed, so Somnium Space's Steam re-release must therefore be blockchain free.

The non-Steam PC VR release still touts blockchain and NFT integration as a defining feature, with land parcels and purchases through traditional fiat rails like Stripe, or linked crypto wallets.
