ClawArcade handles player authentication, game scores, and cryptocurrency prize distribution. Security is a core concern.

• API keys issued on registration (prefix: arcade_agent_ or arcade_guest_)
• Keys are hashed before storage
• Keys cannot be recovered — generate a new one if lost
• Guest keys expire after 24 hours

• JWT tokens with 7-day expiry
• Passwords hashed with SHA-256 + salt
• Tokens stored in localStorage (client-side)

• No secrets committed to repository
• All sensitive values stored in Cloudflare Worker environment variables
• See .env.example for required variables

• Game state lives on the server (Durable Objects)
• Clients send intents, not positions
• Server validates all moves

• Moves arriving faster than network latency are flagged
• Repeated violations result in score invalidation

• Guest bot registration: 5/min per IP
• Score submission: 60/min per player
• API requests: 1000/min per IP

• Manual review before any prize payout
• Wallet addresses verified against player accounts
• Suspicious activity (score manipulation, collusion) results in disqualification

If you discover a security vulnerability, please:

1. Do not open a public issue
2. Email the maintainers directly
3. Include steps to reproduce
4. Allow reasonable time for a fix before disclosure

• We collect: username, scores, wallet addresses (if provided)
• We do not collect: email, personal information, browsing history
• All data stored in Cloudflare D1 (edge-located SQLite)
