The on-chain credit rail
for physical luxury.
Vaulx is a Solana-native protocol connecting physical luxury collateral — watches, jewellery, fine objects — to global on-chain capital. Smart contracts settle every loan. Licensed counterparties hold the asset. We don't take custody. We don't hold capital.
Why we exist
Asset-rich, credit-trapped.
In high-rate markets — Brazil, Mexico, Turkey, India, Southeast Asia — the same person who owns a Patek Philippe pays 60–400% APR on consumer credit. Caixa Federal pawns a watch at 20% loan-to-value and 36% APR. Credit cards charge four hundred. The asset is liquid; the credit is not.
Meanwhile, on-chain institutional capital is the cheapest credit in the world — sitting at 8–10% APR, looking for insured RWA collateral that almost no one supplies. The gap is not interest rates. The gap is the absence of a rail.
How it works
Five gates. One signature.
Every loan flows through a single Anchor program on Solana, gated by five atomic transitions: appraisal, custody confirmation, cNFT mint, USDC borrow, repayment or default. Each gate enforces its precondition on-chain — no custodian sign-off, no credit transfer, no funds movement happens without the prior gate having been verified by the contract.
The signature line is the headline: USDC does not disburse until the licensed custodian's keypair signs custody-confirmation in the same transaction as the borrow. No competitor in physical-collateral lending has shipped this on-chain.
What borrowers pay
One year of credit. Two ways to pay.
Reference: $5,000 borrowed against a $10,000 watch at 50% loan-to-value, in Brazil, over twelve months. Compared like-for-like — the same borrower, the same year, the same collateral.
Why trust us
We don't take custody. We don't hold capital. Smart contracts settle everything.
Atomic gates
Read more →No USDC disburses without on-chain custody confirmation, in the same transaction. The contract enforces every transition.
Licensed custody
Read more →Insured climate-controlled vaults operated by licensed counterparties — different operator per market, same protocol-side controls everywhere.
Lloyd's underwriting
Read more →A Lloyd's master policy covers theft and damage to the trustee on every asset under custody. Coverage is per-asset, re-marked quarterly.
Multisig governance
Read more →Every sensitive instruction (deposit, withdraw, pause, defaults) is gated behind a Squads V4 2-of-3 multisig with timelock. No single key controls anything.
First-loss buffer
Read more →Every loan posts a 5% protocol-owned first-loss reserve. We have skin in the game on every transaction.
Public, audited code

Markets
Where credit is expensive, luxury collateral is everywhere.
Brazil, Mexico, Turkey, India, Southeast Asia, South Africa, Nigeria. The same Solana protocol stack across every market — only custody and offline appraisal swap per country, in 60–90 days.

Built on
Composable with the institutional Solana stack.
We integrate at the protocol level with the public infrastructure already running on Solana. Credit liquidity, identity, smart-wallet auth, and price feeds — read-everywhere, no closed market.
Team
Five founders, five non-overlapping axes.
Banking, physical security, partnerships, Solana engineering, DeFi. No-one is learning the field on the protocol's dime.
