Reya Partners with EigenCloud to Power the First Based Rollup Capable of Institutional-Scale Trading on Ethereum
EigenCloud, the pioneering restaking protocol securing the next generation of Ethereum infrastructure, has announced a strategic partnership with Reya, the first trading-specific based rollup, to bring institutional-scale price discovery and execution fully onchain.
The Problem
Running a high-performance orderbook onchain has always been a fundamental challenge. The continuous flow of orders and updates generates data volumes hundreds of times larger than typical transaction data, far exceeding what general-purpose blockchains can process. Until now, this has made institutional-grade trading on Ethereum impossible.
A Breakthrough for Based Rollups
A based rollup anchors block production directly in Ethereum’s validator set. All transaction data must go to Ethereum itself, giving traders full L1-level security and verifiability. This design removes external trust assumptions but also introduces a massive data bottleneck because onchain trading requires both transaction data and high-frequency order data, which can be 100 to 1,000 times larger.
EigenDA solves that problem. As EigenCloud’s high-throughput, Ethereum-native data availability (DA) layer, it gives Reya dedicated bandwidth to post and verify order data at scale, while transaction data continues to flow directly to Ethereum. Both layers are linked by zero-knowledge proofs, ensuring the entire trading system remains transparent, verifiable, and secure.
Without EigenDA, a based rollup at this scale would not be possible. With it, Reya can operate a fully verifiable onchain orderbook capable of 200,000 transactions per second, bringing institutional-grade performance and market integrity to Ethereum. It’s important to highlight, executed trades still use Ethereum as the DA, without this the rollup wouldn’t be based. But EigenDA allows order data to be made available and verifiable onchain.
Multi-Sequencer Architecture for True Resilience
Reya creates a multi-sequencer architecture designed to expand over time and remove the single point of failure that limits most rollups today. Combined with EigenDA’s horizontally scalable infrastructure, this model enables Reya to process continuous order flow with millisecond-level performance and Ethereum-grade trust.
Completing Ethereum’s Financial Stack
Ethereum perfected settlement. Reya’s based rollup, powered by EigenDA, completes the financial stack by enabling verifiable, institutional-scale price discovery, the missing layer for global onchain markets.
“A based rollup must send its transaction data to Ethereum. The challenge is that order data is hundreds of times larger and cannot exist onchain at scale. EigenDA gives us a way to post that data verifiably and efficiently, making a based rollup for trading truly possible, unlocking unprecedented speed, security and reliability for traders on Reya” said Simon Jones, CEO of Reya Labs.
“With EigenDA and Reya, Ethereum’s financial stack is now complete. We are enabling the same market integrity and performance institutions expect, while preserving Ethereum’s core principles of openness, decentralization, and verifiability,” said Sreeram Kannan, CEO of EigenCloud.
