GaiaEx

GaiaEx is a multi-asset on-chain trading application with a built-in self-custody MPC wallet: users register with an email address, Google or Apple ID, the multi-party computation wallet is created automatically, there is no seed phrase, and the private key is never fully exposed at any point. It addresses the high barrier to non-custodial trading and the fragmentation of multi-asset exposure: the trading engine runs on Arbitrum with USDC on that network as the unified margin, a built-in swap converts other assets into USDC, and roughly 217 instruments are tradable across crypto, tokenised equities, commodities and indices.

On contract structure, USDC-margined perpetuals cover 102 crypto symbols plus 31 real-world and venture symbols at up to 40x leverage, while USDT-margined perpetuals cover 34 symbols at up to 200x leverage, alongside 50 spot pairs. Orders are placed through an agent key derived from a one-time EIP-712 signature that can submit and cancel orders but cannot move collateral, with the main wallet retaining custody.
