About us
Since 2021, Defined users have benefitted from industry leading enriched blockchain data and powerful analytics tools to give them an edge in the competitive space of cryptocurrency trading.
In 2025, we began a complete overhaul of Defined in order to build a fully modular trading experience for our users. This latest version of Defined brings a truly unparalleled trading solution that can be fully customized via "Boards", which can also be shared publicly. We've also moved beyond just token trading, incorporating perps (via Hyperliquid), as well as prediction markets that utilize aggregated prediction market data via Codex (our industry-leading blockchain data API).
Defined utilizes Relay & Turnkey for trading and user authentications, ensuring a fast, safe, and secure experience for our users.
Where do we get our data?
Defined is powered by our Codex API, and TradingView for charts. Want to use our data for your project? Check out Codex.io for more details.
The most reliable and accurate blockchain API
Trading Fees
Our standard trading fee is 0.75%.
Our classic Defined.fi site remains available while we build and you can find our legacy docs in the sidebar.
