Cube Exchange: DeFi, CeFi, MPC

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.
