Funding history
About Reya
Reya operates a high-speed perpetuals exchange as an L2 on Arbitrum Orbit, with zero-gas trading, MEV protection, yield-bearing collateral, and self-custody. It is developing an Ethereum-native evolution using based-rollup architecture, delegated sequencing, and ZK finality. The platform targets traders who want fast, permissionless access to perpetuals, spot markets, staking, and real-world assets without intermediaries.
