Reya 101: Trade Without Compromise

Reya has already secured its spot at the list of top-10 perps DEXes, however, this is just the beginning for us.
We’re building the platform that will change the way you trade forever.

Some things are only possible on Reya.
Let’s dive deeper into it.

What Is Reya

Reya is where you can trade like Ethereum intended - fast, secure, free.

Today, Reya stands among the leading perpetual DEXs, being a platform that’s fast, battle-tested, and trusted by traders who value reliability above all else. Every trade executes at the speed of code, powered by a resilient architecture built to safeguard liquidity and maintain integrity.

With 70+ markets, advanced cross-margining, 100x leverage, a market-leading collateral system supporting assets like wstETH, wBTC, and a native yield-bearing stablecoin, srUSD, Reya empowers both retail and programmatic traders to operate without compromise.

But this is just the beginning for what Reya is capable of.

Reya’s next chapter marks a bold leap forward - a radical engineering breakthrough redefining how onchain markets work.

After years of research and development, the Reya team has accomplished what many thought impossible: a permissionless trading architecture delivering TradFi-level speed of sub millisecond while preserving Ethereum’s security, transparency, and composability. With zero single-sequencer risk, Reya is the world’s first based-rollup DEX.

This innovation is fully verifiable through custom zk-circuits, enabling seamless, high-performance trading for those who demand both speed and trust. It’s a foundation capable of bringing capital formation fully onchain - transforming markets forever.

Reya serves both dApp and programmatic traders. Algorithmic traders will be able to deploy strategies impossible on any other venue due to speed limitations, while dApp users will enjoy zero-fee trading with unmatched performance.

Our mission is simple: we’re reshaping decentralized trading by delivering 100× faster execution, 0 fees, and Ethereum-level uptime and security.

So you can trade Like Ethereum Intended - Fast, Free and Secure. Only possible on Reya.

Why DeFi Needs Reya

Global Capital Markets are moving onchain to Ethereum because it is credibly neutral, has never had downtime, and has the economic security capable of supporting the world’s financial system. However, Ethereum isn’t fast enough to support trading - it simply wasn’t built for it.

Meanwhile, attempts to build fast onchain trading environments have led teams to centralize parts of the trading system. This creates security, reliability, and neutrality concerns for a system designed to be global. These concerns are in direct conflict with the benefits Ethereum provides, and why it has been chosen as the chain for global finance.

Reya solves these issues. We are delivering the DEX with institutional-grade execution and Ethereum-level security. One that is as fast as TradFi but simultaneously secure, reliable, and credibly neutral as DeFi should be.

Fast is easy. Decentralized is hard. Only Reya does both.

Why Reya is Different

Reya is built different.

Previously, the main successful attempts at creating a performant onchain DEXs have been via an alt-L1 or a single-sequencer zk rollup.

Reya is the first-ever trading-specific based zk rollup; a transformational moment for DEX design.

Based-rollups are novel mechanisms through which developers can create isolated and performant application-specific environments that still leverage the security and consensus of Ethereum L1 validators.

These types of rollups haven’t been possible until now due to the recent technical breakthroughs. For example, some of the key technological unlocks, like the introduction of a Deterministic Proposer Lookahead, have only just gotten the required R&D momentum.

Here’s how a based zk rollup is superior to what exists in the market today:

Reya's trading-specific based Zk rollup on Ethereum allows us to achieve superior conditions for our traders:

• Fastest speed of <1 millisecond trade execution (100X faster than the current top DEXes)
• Highest security with verifiable order execution and settlement, via zk-proofs, with trades settled on Ethereum
• Highest reliability without single point of failure thanks to multiple sequencers

The based-rollup design also makes Reya synchronously (atomically) composable with all of Ethereum L1 DeFi, unlocking novel use cases for traders and builders.

No sidecar. No Alt-L1. Instead, the DEX that is enshrined into the Ethereum L1.

Who Reya Is For

Reya is built for traders who demand the highest standards in execution, security, and control from their trading venues. Let’s dive deeper into what each group gets from trading on Reya.

Institutional and Professional Traders

They need speed, stability, and auditability at scale.

Reya delivers:

• Millisecond execution for strategy integrity
• Self-custody and verifiable settlement
• Infrastructure that remains live during volatility
• Unified margin and efficient capital deployment
• Trusted execution environment built on Ethereum

For individuals who trade frequently, Reya delivers:

• Fast fills during market movement
• Transparent execution
• Self-custody without sacrificing performance
• Fair access without privileged intermediaries
• Zero trading fees
• Same quality of execution and security expected by institutions

What Is Next For Reya

Unlocking the breakthrough-based zk rollup design has been an iterative path. To begin with, Reya was launched using a forked and heavily customised version of Arbitrum Orbit. This allowed the product to launch, deliver value to users, and generate the necessary learnings required to unlock the based zk rollup design.

This means Reya will transition to a based rollup iteratively over time without any impact to users. Here’s our roadmap at a glance:

• Stage 0: TGE (expected Q4 2025)
• Stage 1: Orderbook launch (expected Q1 2026)
• Stage 2: Migrate to based design, with single Execution Node (expected Q2 2026)
• Stage 3: Introduce multiple rotating Execution Nodes (expected Q3 2026)

Alongside this infrastructure upgrade, the trading venue will continue with a roadmap covering:

• Spot markets
• RWA-Crypto Perp Expansion
• Launchpad
• srUSD Tokenization

Who is Behind Reya

Reya was founded by Simon and Artur, who are both serial entrepreneurs, having previously built successful financial startups in Web2 and Web3. They are supported by a team of traders and crypto-native builders, with experience at Optiver, Wintermute, Goldman, Coinbase, and Citi.

Reya has raised $12m from investors including Framework, Coinbase Ventures, Wintermute Ventures, Selini Capital, Amber Group, Brevan Howard Digital Assets, and Leadblock Ventures, as well as prominent angel investors like Stani of Aave/Lens, David and Ryan of Bankless, and Kain of Synthetix/Infinex.

TLDR

Reya’s breakthrough design unlocks the only trading venue that delivers:

• Sub-millisecond execution with full Ethereum security
• Verifiable settlement and continuous uptime anchored to Ethereum
• Unified margin across 70+ markets (wstETH, wBTC, srUSD collateral)
• CEX-level performance with true self-custody and neutrality
• The first trading-specific based rollup architecture
