Introduction
Welcome to Predixa
Predixa is a decentralized prediction market platform built on the Arbitrum network. Predict the outcomes of real-world events — from crypto price movements to global market trends — and earn rewards when your predictions are correct. All markets are governed by transparent smart contracts, and payouts are distributed automatically on-chain.
Getting Started
To use Predixa, you need a Web3 wallet compatible with the Arbitrum network — MetaMask, Coinbase Wallet, or any WalletConnect-compatible wallet. Click "Connect Wallet" in the top right corner, select your provider, and approve the connection. Ensure your wallet is connected to the Arbitrum network and holds USDT to place predictions. New to Arbitrum? You can bridge assets from Ethereum mainnet using the official Arbitrum Bridge.
How Prediction Markets Work
Each market presents a binary question with a YES or NO outcome — for example, "Will ETH price go up in 1 hour?" Markets resolve at a predetermined time based on objective data from on-chain oracles. If your prediction is correct, you receive a proportional share of the total pool based on the odds at the time you entered. If incorrect, your stake is redistributed to winning participants. The odds displayed reflect the current probability implied by all staked positions.
Placing a Prediction
Navigate to the Markets page and select any active market. Review the current odds and total pool sizes for YES and NO outcomes. Enter your stake amount in USDT and choose your position. If this is your first prediction, you will be prompted to approve USDT spending for the smart contract — this is a one-time step. Confirm the transaction in your wallet. Your prediction is recorded on-chain immediately and cannot be reversed.
Combo Sets
Combo Sets allow you to bundle multiple market predictions into a single position for higher potential returns. Browse curated preset combos such as "Crypto Bull Run" or "ETH Ecosystem", or assemble your own combination from active markets. Access the Combo Set panel via the button in the bottom-right corner of any page. Select a preset and confirm your stake to enter all included markets simultaneously.
Rewards and Payouts
Winnings are automatically calculated when a market resolves. Navigate to your Portfolio to view settled markets and claim your rewards. Payouts are denominated in USDT and transferred directly to your connected wallet upon claiming. Unclaimed rewards remain available for 90 days after market resolution. Gas fees for claiming are minimal on Arbitrum.
Supported Networks
Predixa currently operates on the Arbitrum One network. Development and testing activities use a private Devnet environment. Cross-chain asset bridging support is available via integrated bridge providers visible in the wallet connection flow. Additional network support may be introduced in future releases.
