Decentralized luxury asset marketplace on Solana
NFT-backed physical assets with verified provenance, on-chain escrow, and tokenized ownership pools.
Website · Features · Access · Security
The $350B+ luxury resale market lacks trustless infrastructure. Buyers can't verify authenticity, sellers face chargebacks, and fractional access doesn't exist. LuxHub solves this:
- Blockchain-verified provenance — every asset tokenized as an NFT with immutable authentication data
- Trustless escrow — funds locked on-chain until physical delivery is confirmed
- Tokenized ownership pools — own luxury watches starting from $1.50, not $100,000
- Secondary market trading — buy and sell pool tokens on Bags DEX
- Institutional-grade security — Squads Protocol multisig for all treasury operations
- AI-powered onboarding — Claude Vision auto-analyzes watch images to fill mint forms in seconds

LuxHub implements defense-in-depth across on-chain and off-chain layers:
| Layer | Protection |
|---|---|
| On-chain escrow | Funds held in program-owned PDA — not LuxHub wallets |
| Squads multisig | All treasury operations require M-of-N approval |
| TX verification | Every fund movement verified on Solana before database update |
| Wallet signature auth | Ed25519 verification on protected API endpoints |
| PII encryption | AES-256-GCM for sensitive data (shipping addresses) |
| Escrow timeouts | Auto-cancel after 14 days if vendor doesn't ship |
| Dispute system | 7-day SLA with admin escalation and refund authority |
| Rate limiting | Strict limits on purchase and AI endpoints |
| Admin gating | ADMIN_WALLETS env var restricts sensitive operations |
