Cube Exchange: DeFi, CeFi, MPC

Cube Group Inc.

About this app

Cube Exchange is a self-custody crypto platform that combines DeFi and CeFi in one app. Create an MPC vault, keep control of your keys, and trade BTC, ETH, SOL, USDC, USDT, and more. Place orders on fast order books or convert instantly with a tap. There’s no centralized custody—your assets stay in your wallet while matched trades settle on-chain for transparent, verifiable activity.

Trade major pairs like BTC/USDC, ETH/USDC, SOL/USDC and more. Use market and limit orders in the Pro view, or make quick swaps when you just want to move from one asset to another. Real-time prices, responsive charts, and alerts help you keep up with the market and act quickly.
