Reya Review: Speed, Security & Ethereum-Based Innovation
Reya is a high-performance, on-chain trading venue built for traders who demand speed, liquidity and decentralised security. It uses a “based-rollup” architecture on the Ethereum ecosystem to deliver millisecond-level trade execution, zero gas for traders, MEV protection and deep liquidity across derivatives and spot markets. Read this Reya Review to discover more about the platform.
What is Reya?
Reya is a next-generation, high-performance on-chain exchange designed to deliver institutional-grade execution with unmatched speed, security, and reliability.
Built as a trading-optimized based zk-rollup on Ethereum, Reya offers sub-millisecond execution, verifiable settlement secured by Ethereum, and a resilient architecture with rotating L2 nodes—eliminating single points of failure.
Its based-rollup design also enables synchronous composability with the entire Ethereum DeFi ecosystem, creating a truly integrated, high-speed DEX experience without sidechains, alt-L1s, or external dependencies.
Reya Review: Why Reya exists?
Global capital markets are moving onchain, and Ethereum has emerged as the only credibly neutral, highly secure, and always-on settlement layer capable of supporting this shift. But while Ethereum guarantees unmatched security, it wasn’t built for high-speed trading.
Attempts to fix this by creating faster environments have often resulted in centralization—sacrificing reliability, neutrality, and the very benefits that make Ethereum the preferred base layer for global finance.
Reya exists to solve this gap by delivering institutional-grade trading performance with Ethereum-level security. It offers TradFi-level speed without compromising decentralization, creating the foundation for true onchain price discovery and globally accessible open markets.

Reya Review: How Reya Is Different
- Reya is built as a trading-specific based zk-rollup, a new architectural model that creates a high-performance environment while still inheriting the full security, neutrality, and consensus of Ethereum L1.
- This design has only recently become possible thanks to breakthroughs like deterministic proposer lookahead, enabling rollups to maintain speed without centralizing execution.
- Historically, fast onchain DEXs have relied on alt-L1s or single-sequencer zk-rollups, both of which introduce trade-offs in security, reliability, and censorship resistance.
- A based zk-rollup eliminates these drawbacks. Compared to other designs, it offers superior economic security (Ethereum L1 proposers), excellent reliability with no single point of failure, full censorship resistance, and true synchronous composability with Ethereum DeFi.
- As the first trading-optimized based zk-rollup, Reya represents a major shift in how high-performance DEXs can be built—combining top-tier speed with uncompromising decentralization.

Reya Review: Cross Margining
Reya’s cross-margining system allows the margin engine to evaluate a trader’s entire portfolio holistically, recognizing when positions offset each other’s risk. This reduces total margin requirements and unlocks significantly higher capital efficiency—especially for long-short or relative-value strategies. By treating the portfolio as a whole, traders and LPs can use less collateral while maintaining strong risk management and on-chain safety.
Key Benefits
- Lower Margin Requirements: Offsetting positions reduce overall portfolio risk, freeing up capital.
- Efficient Long–Short Trading: Ideal for relative-value strategies like ETH–BTC spreads, enabling much higher capital efficiency.
- LP Optimization: Liquidity providers gain major margin savings across large, diversified portfolios, allowing them to deploy more liquidity.
Reya Review: Cross-Collateralization
Reya introduces a flexible margin system that lets users post collateral in any token and seamlessly share PnL across portfolios with different settlement assets. This allows traders to keep preferred or yield-bearing tokens (like stETH) while still backing positions, and enables portfolios in different denominations to support each other automatically. Using a conservative system of “bubbles” and “haircuts,” Reya safely manages collateral mismatches while maximizing capital efficiency.
Key Benefits
- Any-Token Collateral: Use assets like ETH, stETH, or other tokens as margin while still holding and earning from them.
- Cross-Asset PnL Sharing: Combine portfolios in different settlement tokens, allowing one portfolio to support another when needed.
- Safe Risk Management: A bubble-and-haircut model adjusts for price movements, minimizes unnecessary conversions, and keeps margin levels secure.

Reya Review: Native Stablecoin
Reya Network uses rUSD as its native settlement stablecoin, ensuring neutral and consistent PnL settlement across the system. rUSD is currently wrapped USDC bridged to Reya, automatically wrapped when deposited and freely unwrappable whenever it’s not used as margin.
Reya also offers srUSD, a staked version of rUSD that provides diversified, protocol-level yield through Reya’s unified liquidity model.
Key Points
- rUSD for Settlement: Acts as Reya’s chain-agnostic settlement stablecoin, enabling clean PnL settlement across all markets.
- Wrapped USDC Design: USDC deposits become rUSD automatically; users can unwrap anytime if the funds aren’t locked as margin.
- srUSD for Yield: Staking rUSD mints srUSD, giving users access to Reya’s more diversified and efficient liquidity provisioning yield.
