What is Yield Quest?

Yield Quest is an innovative prediction market platform that transforms the way users engage with DeFi. Instead of risking your principal on predictions, Yield Quest enables you to play with only the yield generated from your staked weETH. Your principal remains 100% safe and withdrawable at any time—creating a truly no-loss gaming experience.

Think of it as a gamified yield layer on top of EtherFi's liquid staking, where you can test your prediction skills, compete with others, and earn rewards—all without putting your capital at risk.

Core Concept

  1. Deposit weETH → Your principal is locked safely in a vault
  2. Earn Yield Credits (YC) → Your principal generates YC over time (simulated 5% APR)
  3. Make Predictions → Spend only YC on binary YES/NO prediction markets
  4. Win & Level Up → Correct predictions earn more YC, boost your level, and unlock achievements
  5. Withdraw Anytime → Your principal is always yours, completely risk-free

How It Works

The No-Loss Mechanic

Traditional prediction markets require you to risk your own capital. Yield Quest changes this paradigm:

  • Principal Protection: Your weETH is stored securely in a smart contract vault and never used for betting
  • Yield-Only Betting: Only the Yield Credits (YC) generated from your principal can be used for predictions
  • True Risk-Free: Even if you lose all your bets, your principal remains untouched and fully withdrawable
  • Sustainable Gameplay: As long as you have principal staked, you continue earning YC to play with

Prediction Markets

Engage with diverse binary prediction markets covering:

  • Cryptocurrency prices and trends
  • Sports outcomes
  • Technology developments
  • Political events
  • Science and research breakthroughs

Each market features:

  • Clear YES/NO questions
  • Difficulty ratings (1-5 stars)
  • Close times for resolution
  • Dynamic odds based on pool distribution
  • Admin-verified outcomes
