About Rome Protocol
Rome Protocol is a shared sequencer built on Solana. It allows rollups (like OP Stack chains) to use Solana as their transaction ordering and execution layer. Its core business is twofold: the Rhea API packages rollup transactions and submits them to Solana for execution, while the Remus API enables atomic cross-rollup transactions, letting searchers bundle operations across multiple chains in a single Solana transaction.
The core value proposition is solving liquidity fragmentation and interoperability issues among rollups. By using Solana as a shared sequencer, rollups gain fast finality (~400ms), shared liquidity, and atomic composability — meaning assets and data can move across rollups without bridges or message delays. It also provides economies of scale, as multiple rollups share the same sequencer infrastructure.
The market pain point is that existing rollups have isolated sequencers, leading to fragmented liquidity, poor cross-chain interoperability, and slow cross-rollup transactions. Rome addresses this by making Solana the common settlement and ordering layer.
In the past six months (2026-02-28 to 2026-08-31), Rome Protocol has progressed with the Rhea API processing transactions from OP Geth mempools, the Remus API enabling cross-rollup atomic bundles, and the deployment of Compound v3 (Comet) on Rome. The team has also published documentation on integrating OP Stack rollups with Rome, using Solana as the state machine and data availability layer.
Over the past six months (2026-03-02 to 2026-09-02), Rome Protocol, a shared sequencer leveraging Solana, has made significant strides. In July 2026, the project released its initial public version (commit b07d909) of the rome-bridge-api, a stateless HTTP API for bridge primitives (Circle CCTP, Wormhole, Solana SPL flows), marking a key milestone for integrators. The core architecture—using Solana as the state machine and data availability layer for EVM rollups—has been validated through working implementations, including the Rhea and Hercules components that enable atomic cross-rollup transactions and efficient block sequencing. The project has also published a novel approach to based sequencing for Ethereum L2s, using Solana as a shared sequencer to achieve fast finality without complex preconfirmation mechanisms. Future development focuses on expanding the Rome SDK (typed Solana interfaces), enhancing the Meta-Hook Router for Token-2022 transfer hooks, and maturing the DeFi Composer for multi-protocol vaults. The team plans to launch a devnet soon, with ongoing research into fast finality, state consistency, and production deployment. The roadmap emphasizes app sovereignty, allowing each application to have its own EVM environment with custom gas tokens, while maintaining atomic composability across the Solana ecosystem.
Rome Protocol was co-founded by Sattvik Kansal and Anil Kumar. Sattvik Kansal (Co-founder) previously worked at Plaid (Engineering, 2017-2023) building payment products for Europe & US, and interned at Google, Shopkick, and Yorango. He holds a BS in Computer Science from Cornell University. Anil Kumar (CEO) brings over 25 years of experience in financial services, having held senior product management roles at JPMorgan Chase and Deutsche Bank (as Assistant Vice President). He also co-founded Coin Vesting, a crypto treasury management platform. Together, they lead Rome Protocol, which modularizes Solana into shared sequencers and DA solutions for Ethereum L2s.
