About the company
ProofChain is a product of HKMM Group Inc.
We're a Canadian company building the trust layer for North American homes — starting in Canada, spreading across the continent. Every home deserves a verified history: permits, work, warranties, inspections, insurance, and ownership — cryptographically anchored, portable across owners, and controllable by the person who lives there.
Legal entity
HKMM Group Inc., an Ontario corporation. All commercial relationships, contracts, and payments run through HKMM.
Headquartered
Ontario, Canada. Operating across all provinces and territories. Expanding into the United States in phase 2.
Compliance-first
PIPEDA, Quebec Law 25, BC PIPA, Alberta PIPA, CASL, AODA. Governed by Canadian law, disputes seated in Toronto.
Our mission
Homes are the largest transaction most Canadians will ever make — and the least transparent. Carfax fixed that for cars. ProofChain does it for the built world: a verified, tamper-evident history that follows the property, not the owner.
