Universal microtask exchange on Solana — instant stablecoin rewards for micro-labor.

---

What is PayTask?

PayTask enables anyone to post or complete micro-tasks ($0.50–$50) with instant stablecoin payments on Solana.

The Problem: Web2 payment fees ($0.30+ fixed) make tasks under $5 unprofitable. This kills 95% of micro-work opportunities — a $500B stranded market.

The Solution: Solana stablecoin escrow ($0.00025 fees) makes micropayments viable for the first time. Workers earn instantly, clients get proof-of-human work AI can't fake.

Key Features

• ✅ Escrow-protected payments — funds locked until completion or 48h auto-release
• ⚡ Instant USDC/USDT payouts — sub-second settlement, borderless
• ⭐ On-chain reputation — portable ratings, completion tracking
• 🔍 Quality assurance — proof submissions + LLM screening + disputes
• 📱 Mobile-first — 1-tap acceptance, 3-tap posting flow
• 🌍 Global access — no minimums, KYC only at $200+

Use Cases

Workers: Earn $3-6 in 15 minutes (surveys, UX testing, AI labeling, local research)
AI Companies: Human validation 10x cheaper than Scale AI
Businesses: On-demand micro-research and proof-of-action tasks

Core Workflows

Worker Flow

Browse tasks → Accept (1-tap) → Complete work → Submit proof → Get paid instantly

Client Flow

Create task → Fund escrow → Workers complete → Review/Auto-approve → Funds released

Smart Contract Flow

Client → escrow_lock() → Task published
Worker → accept_task() → Assignment created  
Worker → submit_work() → QA checks run
Client → approve() → payout_release() → Worker receives USDC
OR timeout → auto_approve() → payout_release()
