How can we help?

You can get USDC on Polygon through:

• Buy USDC directly in-app with Coinbase (card onramp via Privy)
• Centralized exchanges (Coinbase, Binance, Kraken) — withdraw USDC to Polygon network
• Bridge from Ethereum using the Polygon Portal
• Decentralized exchanges on Polygon (QuickSwap, Uniswap)
• On-ramp services like MoonPay or Transak

You'll also need a small amount of POL for gas fees (typically <$0.01 per transaction).

Odds reflect the implied probability of an outcome. We display odds in cents (0-100¢) where:

• 50¢ = 50% implied probability (even odds)
• 25¢ = 25% implied probability (3:1 payout)
• 75¢ = 75% implied probability (0.33:1 payout)

Lower prices mean higher potential returns but lower probability.

Markets can be resolved through:

• Manual Resolution: The market creator or designated authority determines the outcome based on real-world events.
• Random Resolution: Some markets resolve based on verifiable data sources for outcomes like lottery-style events.

4rho charges minimal fees:

• Platform Fee: A small percentage (typically 2-3%) is deducted from the winning pool
• Network Fee: Standard Polygon transaction fees (typically <$0.01)
• No deposit or withdrawal fees

Common causes and solutions:

• Insufficient USDC: Ensure you have enough USDC for the trade plus a small amount of POL for gas
• Network congestion: Try again in a few minutes
• Wallet disconnected: Reconnect your wallet and retry
• Market closed: The market may have ended - check the market status
