Intro to Sai

Trade, earn, burn.

Welcome to Sai.fun—a perpetual futures trading platform built on Nibiru. With Sai, you can open leveraged positions (long or short) with low fees and low impact trades, set limit orders, stop-losses and take-profits, or earn yield in a fully onchain trading experience.

Sai is in active development with an expected launch in early 2026. The team has finalized a smart contract audit on the core protocol logic, and the web application is under active development.

In the meantime, please follow Sai on X to help support us.

Why Sai?

• Oracle settlement: Simple and easy price behavior so there's no internal surprises. We rely on a combination of Nibiru's Oracle, which aggregates prices from leading exchanges like Binance, Bybit, and OKX through Nibiru's decentralized validator network, and custom feeds for certain markets.

• Leverage: Amplify your exposure with up to 100x leverage (exact max set by each market and pairs).

• Simple On-Chain Experience: Manage everything in one intuitive UI, leveraging one click trading, automated order triggering, etc.

• Custom Orders: Market, limit, stop, and advanced triggers for Take Profits and Stop Losses.

Use the sidebar navigation to jump to any topic or type a keyword (e.g. "leverage," "limit order") in the search bar.
