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 prediction market venues, enabling users to receive the most updated view of a particular market and the best respective execution.
Vistadex architecture: Users submit orders via the Vistadex API, which routes to the OrderService. Fillers compete in an auction, and the winning bid is settled on-chain via Vistadex Exchange smart contracts on Solana.

Cross-Venue Matching

Vistadex designates a reference platform for each market (Polymarket, Kalshi, etc.). At resolution, Vistadex resolves 1:1 with the reference market in real time. When you request a quote for a market, Vistadex runs a real-time auction against a set of fillers across all venues with matching markets. Fillers compete to give you the best price from any liquidity source. If splitting your order across multiple venues yields a better price, fillers with better routing earn the right to fill your order by winning the auction on Vistadex. For single-venue markets, your trade incurs no fees. For cross-venue markets, a 0.25% fee is applied, when users directly benefit from Vistadex.
