What is Reya?

Reya is a perpetuals DEX built as a based zk-rollup on Ethereum, currently running as an L2 on Arbitrum Orbit. Traders bridge USDC or yield-bearing collateral like srUSD and wstETH, then trade more than 70 markets including crypto perps and RWA perps with sub-millisecond execution and zero gas fees. Trades are verifiable onchain via zk-proofs and protected by a FIFO matching design that limits MEV.
