Residential Sales on PYRAX
Residential sales moves homes between buyers and sellers through a chain of agents, escrow companies, title insurers, and lenders, where a single closing can take 30-50 days and stack thousands in intermediary fees. PYRAX collapses that chain into one atomic transaction - title, funds, and payoff move together or not at all - with shielded valuations and a viewing key that gives the county recorder a tamper-proof, auditable record.

What's broken today
How PYRAX transforms it
Concrete network elements mapped to this business.
Atomic title transfer + on-chain escrow
Buyer funds, seller payoff, and the title token settle in a single transaction - the deed only transfers if the money clears, removing the separate escrow agent and the wire-fraud window entirely.
Shielded-by-default ZK transfers
Sale price, deposit, and buyer/seller identities stay hidden on-chain, while a scoped viewing key lets the county recorder and closing auditor verify the transfer without publishing private financials.
eth_getProof tamper-proof title
Every title token carries a Merkle-Patricia inclusion proof, so any party can cryptographically verify current ownership against chain state without trusting a central registry copy.
BLS proof-of-stake finality
Once the block seals, the sale is irreversible in seconds - no rescission window, no clawback, no multi-day funding limbo between deposit and recording.
PYRAX Compute verifiable AVM valuation
An automated valuation model runs with a cryptographic proof of its inputs and output, so a listing or appraisal price can be shown to a buyer or lender as fair and reproducible.
