## Zeta X (ZX): Building a Trustless Layer 2 for Decentralized Derivatives Trading on Solana

### Abstract

> We present our initial approach to scaling decentralized perpetuals trading through an optimistic rollup built on Solana that leverages zero-knowledge proofs for trustless on-chain settlement. The rollup will use an off-chain matching engine to achieve performance on par with centralised exchanges whilst leveraging the transparency and security of Solana L1 for data availability (DA) and settlement.
