System FAQ

Is this real money trading?
Yes. Precedence is an interface built on top of the Polygon blockchain. You trade using USDC (USD Coin), a stablecoin pegged 1:1 to the US Dollar. All settlements are guaranteed by smart contracts.
How accurate are the AI Judge profiles?
Our models quantify judicial bias by analyzing citation networks and ruling histories. While no AI can predict the future with 100% certainty, our "Judge Scorecards" have shown a 74% correlation with ruling outcomes in preliminary backtests.
Do I need a crypto wallet?
Yes. To maintain non-custodial security (meaning we never hold your funds), you must connect a Web3 wallet like MetaMask or Phantom. This ensures your assets remain in your control at all times.
Where does the legal data come from?
We rely on CourtListener, a non-profit maintaining the most comprehensive open database of US legal opinions and filings. Our API ingestion pipeline updates market data within milliseconds of a docket update.
