Grevlin Property Auction

Real-time competitive bidding for property portfolios — verified bidders, hash-chained ledger, multi-currency deposits and instant bus.bus broadcasting.

🟢 Live Bidding 🔒 Immutable Ledger 📄 KYC Verified

Everything Your Auction Needs

🔴 Live Real-Time Bidding
bus.bus channel broadcasting delivers every bid instantly to all connected browsers. PostgreSQL row-level locking (SELECT FOR UPDATE) prevents race conditions in concurrent bid storms.
🔒 Hash-Chained Bid Ledger
Every bid is SHA-256 hash-chained and PostgreSQL RULE–enforced (no UPDATE or DELETE on the ledger table). HMAC-signed PDF export provides auditor-ready proof of integrity.
📄 KYC Identity Verification
Multi-document KYC wizard on the website. Managers approve/reject submissions. Bidder status (active/suspended/flagged) gated by can_bid computed flag.
🚀 Anti-Snipe Soft Close
Configurable soft-close window (minutes). Any bid in the window extends the deadline. Extension count tracked and broadcast to all viewers. Prevents last-second sniping.
🤖 Auto-Bid Engine
Bidders set a maximum amount. The engine automatically responds when they are outbid, up to their ceiling. Increment tiers override flat increments based on current high bid.
💳 Deposit Escrow
Deposits flow through account.move journal entries. States: pending → held → applied/refunded/forfeited. Winner deposit applied to final purchase; losers auto-refunded on resolution.
🌐 Public Auction Website
Full website integration: filterable catalogue, calendar view, live room with countdown, bid feed, watchlist, auto-bid panel, broker enquiry form. PWA manifest for mobile install.
📱 Mobile-First
Responsive Bootstrap layout with safe-area support. WCAG 2.1 AA accessible controls (focus-visible, ARIA). Countdown timers, bid flash animations, and drag-and-drop KYC upload.
📊 OWL Admin Dashboard
Pipeline banner (Draft/Published/Open/Soft Close/Closed/Resolved) + KPI panel (bids today, pending deposits, pending KYC, flagged bidders). Live monitor action per auction.
