Rome Protocol

Rome Protocol turns Solana into a shared sequencing and execution layer for Ethereum Layer 2 rollups. In this BLOKC-hosted session, Arpit, a core developer and launch manager at Rome Protocol, walks through the architecture and its ties to Solana Labs, Interstate, and the broader open-source EVM and OP Stack communities.

What the session covers

Arpit breaks down how an EVM rollup can keep full Ethereum compatibility while borrowing Solana’s parallel throughput. Two internal components do the heavy lifting. Ria pulls transaction inputs from an L2 mempool and rewrites them as native Solana transactions, giving the rollup fast and fair sequencing. Hercules then bundles the scheduled blocks and settles them back onto their destination chains. Because the EVM environment stays intact, builders keep using Solidity, Hardhat, and MetaMask as usual. A partnership with Interstate adds execution pre-confirmations, which bring sub-second validation and lower gas costs.

What you can build

The goal is to close the gaps that come from fragmented cross-chain liquidity and state. With the Rome SDK, developers get atomic transaction frameworks: Remus handles cross-rollup state execution, while Ramulus manages cross-chain interactions. Together they let you build dApps where a user completes multi-hop operations in a single signature. For example, someone could use an Ethereum wallet to buy a real-world asset listed on Solana without juggling bridges or multiple confirmations.

What’s next

Rome is moving toward a public testnet and Mainnet. The roadmap extends shared sequencing to integrate natively with Bitcoin and Cosmos, broadening the chains it can serve. Rome also plans an institutional grant program and a developer incubation pipeline aimed at app-specific chains that roll up to Solana.
