Mortgage Lending on PYRAX
Mortgage lending is a multi-week gauntlet of origination, underwriting, funding, recording, and secondary-market sale, riddled with document handoffs, wire risk, and privacy tradeoffs. PYRAX makes the loan a programmable contract that funds atomically against the title, streams servicing payments, and keeps borrower financials shielded while lenders and auditors hold viewing keys.

What's broken today
How PYRAX transforms it
Concrete network elements mapped to this business.
Atomic funding + on-chain escrow against title
Loan proceeds disburse in the same transaction that records the lien on the title token - the mortgage and the money bind together, closing the funding-to-recording gap where fraud lives.
Programmable loan servicing
The loan contract meters principal, interest, escrow, and payoff automatically, so servicing transfers hand over a self-describing, always-current ledger rather than a reconciliation project.
Shielded-by-default ZK transfers
Borrower income, balance, and payment history stay private on-chain, while the lender, servicer, and a regulator use viewing keys for read-only, auditable access.
eth_getProof tamper-proof lien
The lien position is verifiable by inclusion proof against chain state, so buyers of the loan or the MBS can confirm collateral and seniority without trusting a servicer's records.
PYRAX Compute verifiable underwriting
Credit-decision and affordability models run with verifiable compute, so an approval or denial can be proven consistent and non-discriminatory to a regulator.
