General

Vistadex is a prediction markets meta-aggregator. All integrated prediction market venues are presented in a unified interface and tradable via a single account on Solana. Vistadex matches equivalent markets across venues, enabling users to receive the best execution.
Vistadex only charges a fee when you are trading an event with cross-venue matched markets. The fee for cross-venue matched markets is 25 bps (0.25%).
No. Vistadex is non-custodial. Your funds and positions are held in your own wallet. We never have access to your private keys or the ability to move your assets.

​
Trading

When you request a quote, our system runs a competitive auction to find the best available price. You see the final price upfront. What you see is what you pay.
Quotes may not be available if:
  • The market has very low liquidity
  • Your order size is too large for available liquidity
Try reducing your order size or waiting for market conditions to improve.
Quotes are valid for a short window. If you don’t confirm in time, request a new quote. Prices may have moved based on market conditions.
Currently, Vistadex only supports market orders. Each trade requires requesting and accepting a quote at the current price.
There’s no strict minimum. Many trades fill on a single venue with no fee at all, making even small trades economical.

​
Markets

Vistadex supports binary prediction markets: YES or NO outcomes. Categories include politics, sports, crypto, and current events. Each market has a specific question and resolution criteria.
Markets resolve based on their stated resolution criteria after the event occurs or deadline passes. Resolution sources vary by market but typically rely on official announcements or verified data.
In rare cases where a market cannot be resolved fairly, it may be voided. Voided markets typically return collateral to participants. Check the market’s specific terms for details.

​
Wallet & Funds

Vistadex uses email login. Enter your email address and verify with the code sent to your inbox. A wallet is automatically created and secured for your account.
You need USDC on Solana specifically. USDC on Ethereum, Polygon, or other chains must be bridged to Solana before it can be used on Vistadex.
Your prediction market shares are held in your wallet. You maintain full custody of your positions.

​
Troubleshooting

Common reasons for failed transactions:
  • Quote expired before confirmation
  • Network congestion
  • Insufficient USDC balance
Try again. If problems persist, try logging out and back in.
Positions appear after your trade confirms, which usually takes a few seconds. If it’s been more than a minute:
  • Refresh the Vistadex page
  • Ensure you’re logged in with the correct email account
Once you accept a quote and confirm, that price is locked. If you see a different price, you may have let the original quote expire and received a new one. Always review the confirmation details before confirming.
Click your wallet address in the header and select “Disconnect.” This ends your session but doesn’t affect your positions or balances.
