1. Getting Started
PredictWin lets you predict crypto token prices on Robinhood Testnet. You can pick whether a token price will go above or below a target by a chosen date (e.g. Will ETH be above $3,000 this Friday?). If you are correct, you win a share of the pool.

Three Ways to Use PredictWin
1. Trade Markets
Pick YES or NO on any token target (e.g. Will PEPE be above $0.000015 next week?).
2. Use Platform Balance
Deposit testnet ETH once (e.g. 0.05 ETH) to place instant 1-click trades without wallet popups.
3. Create Your Own Market
List a market for any token and earn a 1% fee on every trade made by other users.
2. How Trading Works
Every market asks a simple YES or NO question (e.g. Will SOL be above $180 by Sep 30?).
If you think the target will be met, buy YES. If you think the target will not be met, buy NO.
Share prices range from 1¢ to 99¢ based on what the crowd thinks. When the market ends, each winning share pays out $1.00, while losing shares pay out $0.00.
3. Platform Balance (Fast 1-Click Trading)
Normally on Web3 apps, your wallet asks you to confirm every single bet. This can be slow when token prices move fast.
PredictWin includes an In-Platform Balance. You deposit testnet ETH into the smart contract once (e.g. 0.05 ETH). After that, your trades execute instantly with one click.
You stay in full control at all times. You can withdraw your deposited balance and winnings back to your personal wallet whenever you want.
4. Creating Markets & Earning 1%
Anyone can list a new prediction market for any crypto token:
Step 1: Pick a Token
Paste any token contract address or select a popular token (e.g. SHIB, BONK, DOGE).
Step 2: Choose Price & Date
Set a price target (e.g. $0.000030) and choose the deadline date.
Step 3: Pay Listing Fee & Earn
Pay a small listing fee of 0.002 ETH. You automatically earn 1% of every trade on your market.
5. Odds & Payouts
All wagers go into a shared pool. The percentage of funds on YES and NO determines the current odds.
NO Price = NO Pool / Total Pool
Example: If the YES pool has $70 and the NO pool has $30 (total $100), the YES price is 70¢ and the NO price is 30¢. If YES wins, winning YES holders split the prize pool in proportion to their shares.
6. Market Resolution
When the deadline date is reached, trading stops. The closing market price is verified using real-time DexScreener price feeds:
• YES wins: The token price reached or passed the target price (e.g. target was $0.000179 and closing price was $0.000185).
• NO wins: The token price did not reach the target price before expiration.
• Claiming: If you held winning shares, you can click Claim to receive your payout immediately.
