What is PropChain?

PropChain is a marketplace for tokenizing real-world assets — houses, land, phones, and gadgets — as NFTs. Every listing passes through AI-driven document and identity verification before it can ever be minted, so what you see on the marketplace has already been checked, not just claimed.

Ownership documents, survey plans, and identity checks are verified off-chain, then a hash of the underlying documentation is stored on-chain. Anyone can confirm that hash hasn't changed since the asset was approved — without needing to trust a middleman's word for it.

PropChain is being built on X Layer, OKX's Ethereum L2, with support for buying across ETH, Base, and X Layer. It started as a submission for the OKX BuildX AI Season Hackathon and is under active development — pricing, negotiation, and escrow all run through audited smart contracts, currently live on testnet.
