# What Is Reya

Reya is a breakthrough high-performance onchain exchange that delivers institutional grade execution, whilst delivering superior speed, security and reliability guarantees to users.

Reya achieves this as **a novel trading-specific based Zk rollup on Ethereum.** This design gives users superior:

* Speed: <1ms trade execution
* Security: verifiable order execution and settlement, via zk-proofs, with executed trades settling on Ethereum
* Reliability: no single point of failure, with the rollup design having multiple rotating L2 nodes (unlike generation-1 rollups)

The based-design also makes Reya synchronously composable with all of Ethereum L1 DeFi, unlocking novel use cases for traders and builders. No sidecar. No Alt-L1. Instead, a DEX enshrined into the Ethereum L1.
