What is croa?

croa is a mobile app for managing market making on Polymarket. It combines market data, large-trade and strategy signals, liquidity provider (LP) strategies, fund management and performance review.

Which trading and market-making tools does croa offer?

croa supports limit orders, market orders, take-profit/stop-loss (TP/SL) and stop orders, alongside order books, charts and live sports scores. LP strategies let you set buy and sell legs together, track runtime and daily rewards live, and claim rewards after settlement.

Which platforms does croa support, and how can I download it?

croa is designed for iOS and Android, with Chinese and English support. Downloads include iOS, Google Play and Android APK. An iOS button labeled TestFlight links to the beta channel; App Store indicates a store listing. “Coming soon” means that channel has no download link yet.

Can I trade on the croa website?

The croa website provides product information and downloads, without account sign-in, deposits or trading. Market, order and earnings screens are illustrative previews, and the walkthrough does not execute real trades. Use the croa app for actual account activity.

How do croa’s funding and trading accounts work?

In the croa app, deposit USDC into your funding account, convert and move it into your trading account, then place an order or start a strategy. The app records deposits, withdrawals, transfers and conversions. Follow the in-app instructions for each action.

What account security settings does croa offer?

croa offers two-factor authentication (2FA), email verification and a separate trading password. You can also connect Telegram for notifications. Account security settings do not remove trading risk. Only use funds you can afford to lose.
