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
