### About us

Since 2021, Defined users have relied on industry leading blockchain data and analytics tools to get an edge in crypto trading.

Defined now brings every on-chain market into one interface: tokens, perpetuals (via Hyperliquid), prediction markets (via Polymarket and Kalshi), and sports. You trade everything in USDC across any supported chain, and we handle the routing so you never need to bridge. Defined uses Relay for trading and Turnkey for authentication, so your experience stays fast and secure. There is also a companion iOS and Android app that shares your account, wallets, data, and assets.

### No paid trending

Defined has never had paid trending. If a token is trending, it is because of its on-chain metrics, not because someone paid to be there. We do not let creators or users pay to appear on a trending list or insert scam links. Trending stays organic.

### Where we get our data

Defined is powered by our Codex API, and [TradingView](https://www.tradingview.com/) for charts. Want to use our data for your project? Check out [Codex.io](https://codex.io/?utm_source=defined\&utm_medium=docs\&utm_campaign=welcome-page) for more details.

### Mobile app

Defined is available on iOS and Android at [mobile.defined.fi](https://mobile.defined.fi/rgBf/wgklaiy3). The app shares the same account, wallets, and cash balance as the web platform, so you can trade tokens, perps, and predictions on the go.

{% hint style="info" %}
Coming from Defined Classic? The old app and your existing wallets stay available at [un.defined.fi](https://un.defined.fi), and its docs remain in the sidebar under **Defined (Classic)**. To use the new Defined, create a new account and wallets at [defined.fi](https://defined.fi), then transfer your assets over. You can export your watchlists from Classic and import them into Defined.
