Security & trust
How we keep your funds, data, and predictions safe.
Smart contract architecture
Predex smart contracts are deployed on BNB Chain Mainnet. Key design principles:
- Non-custodial predictions: Your funds are locked in smart contracts during a market, not held by us.
- Chainlink Oracle integration: Price data comes from tamper-proof decentralized oracles.
- Automatic payouts: Winners are paid automatically by the contract — no manual intervention.
- Open and verifiable: Contract addresses are public and viewable on BscScan.
Wallet options
MetaMask (Non-custodial)
You control your private keys. Predex never has access to your funds. Best for crypto-savvy users who want full custody.
Email (Managed wallet)
Platform manages wallet for convenience. Encrypted private keys stored securely. Ideal for newcomers. You can withdraw to a personal wallet anytime.
Infrastructure security
- • HTTPS-only connections with TLS encryption
- • Database encryption at rest (MongoDB Atlas)
- • JWT token-based authentication with secure secrets
- • Rate limiting on all API endpoints
- • Password hashing with bcrypt (for email users)
- • Deployment via Vercel + Railway (SOC 2 compliant providers)
User best practices
Protect yourself
- • Never share your MetaMask seed phrase with anyone
- • Verify you're on predexmarkets.com (check URL)
- • Only send USDT via BEP-20 (BNB Chain) — other networks = permanent loss
- • Use strong passwords for email accounts
- • Never predict with funds you can't afford to lose
