Project Documentation

How the interface, market data, wallets and on-chain actions work.

01 · Overview

What is Vanta Markets?

Vanta Markets is an independent prediction-market discovery interface. It organizes public market information into a fast, wallet-aware dashboard and sends trade execution to the corresponding official Polymarket market.

The product is open to everyone. Holding a VANTA token is not required to browse markets, connect a wallet or use any current feature.

Current product scope

  • Browse and filter active public prediction markets.
  • View YES/NO probability, 24-hour volume and resolution date.
  • Calculate indicative shares and maximum payout.
  • Open the matching official venue for order execution.
  • Connect OKX Wallet, MetaMask, Rabby or another injected EVM wallet.
02 · Data

Market data

Market questions, probabilities, volume, dates and slugs are synchronized from Polymarket's public market feed. The page requests a fresh snapshot when it opens, when you press Refresh, and periodically while it remains open.

Displayed probabilities are rounded for readability. They are informational and can move before an order reaches the execution venue.

If the live feed is temporarily unavailable, Vanta keeps the latest synchronized snapshot visible and labels its status in the market toolbar.
03 · Trading

How a trade works

Connect a funded Polygon EOA wallet, select a market and choose YES or NO.
Enter a maximum pUSD spend and review the estimated shares.
Confirm the FAK market order, then approve account authentication and the EIP-712 order signature in your wallet.
Vanta's backend validates and relays the signed order to Polymarket. Available liquidity fills immediately and any remainder is cancelled.

Vanta never receives your private key and does not custody funds. Polymarket may reject an order because of balance, allowance, liquidity, wallet type or regional restrictions.

04 · Wallets

Wallet connections

The interface supports OKX Wallet and standard browser-injected EVM wallets such as MetaMask and Rabby. Connecting reveals your public address, current network and POL balance.

  • Vanta never asks for a seed phrase or private key.
  • A wallet action occurs only after you approve it in the wallet.
  • Use Polygon for the included gas-verification action.
  • Disconnect or change accounts from your wallet extension.
05 · On-chain

Gas verification contract call

The Contract page sends an empty-data, zero-value transaction to Polygon's identity precompile at 0x0000…0004. The call is stateless: it does not approve tokens, transfer assets or change application state.

You still pay the Polygon network gas shown by your wallet. Always verify the destination, value and network in the wallet confirmation window before signing.

06 · Token

VANTA and Robinhood

VANTA is presented as a planned ecosystem token with an intended Robinhood launch. No token is required for current product access, and no token sale is conducted through this interface.

07 · Support

Risks & frequently asked questions

Does Vanta hold my money?

No. The interface does not custody user funds or private keys.

Can I execute a Polymarket order inside Vanta?

Yes, with a supported funded Polygon EOA wallet. The wallet signs the order and Vanta relays it to Polymarket. Smart-wallet and session-key onboarding will be added separately.

Why can prices differ?

Markets move continuously. Rounded dashboard probabilities may differ from the executable order-book price, especially while a page is refreshing.

Are prediction markets available everywhere?

No. Access and trading eligibility depend on your location and the official venue's terms. Users are responsible for complying with applicable laws and platform restrictions.
