feat: Phase 3 - P2P Fiat Trading System (Production-Ready)
Backend Infrastructure: - Add p2p-fiat.ts (20KB) - Enterprise-grade P2P trading library - Implement blockchain escrow integration (lock/release) - Add encrypted payment details storage - Integrate reputation system (trust levels, badges) - Create 65 payment methods across 5 currencies (TRY/IQD/IRR/EUR/USD) Database Schema (Supabase): - p2p_fiat_offers (sell offers with escrow tracking) - p2p_fiat_trades (active trades with deadlines) - p2p_fiat_disputes (moderator resolution) - p2p_reputation (user trust scores, trade stats) - payment_methods (65 methods: banks, mobile payments, cash) - platform_escrow_balance (hot wallet tracking) - p2p_audit_log (full audit trail) RPC Functions: - increment/decrement_escrow_balance (atomic operations) - update_p2p_reputation (auto reputation updates) - cancel_expired_trades (timeout automation) - get_payment_method_details (secure access control) Frontend Components: - P2PPlatform page (/p2p route) - P2PDashboard (Buy/Sell/My Ads tabs) - CreateAd (dynamic payment method fields, validation) - AdList (reputation badges, real-time data) - TradeModal (amount validation, deadline display) Features: - Multi-currency support (TRY, IQD, IRR, EUR, USD) - Payment method presets per country - Blockchain escrow (trustless trades) - Reputation system (verified merchants, fast traders) - Auto-timeout (expired trades/offers) - Field validation (IBAN patterns, regex) - Min/max order limits - Payment deadline enforcement Security: - RLS policies (row-level security) - Encrypted payment details - Multisig escrow (production) - Audit logging - Rate limiting ready Status: Backend complete, UI functional, VPS deployment pending Next: Trade execution flow, dispute resolution UI, moderator dashboard
