# What Is Scroll? Scroll RPC Node - By Denis Perepelitsyn - June 22, 2026 - [Web3 Infrastructure & RPC](/blog/?category=Web3%20Infrastructure%20%26%20RPC) ![What Is Scroll? Scroll RPC Node](/img/blog/post81.png) Crypto-Chief, a top-tier RPC node provider, was among the first Web3 infrastructure platforms to add support for [Scroll RPC ](https://crypto-chief.com/rpc/scroll/)endpoints. ## Key Takeaways - **Scroll is a zkEVM Layer 2 built to scale Ethereum.** - **It uses zero-knowledge proofs to verify batches of transactions before posting them to Ethereum.** - **Scroll is EVM-equivalent, allowing existing Ethereum smart contracts to run without modification.** - **Developers can deploy Solidity applications using the same tools as Ethereum, including MetaMask, Hardhat, and Foundry.** - **Security is inherited from Ethereum while transactions become faster and more cost-efficient.** ## Table of Contents - [What Is Scroll?](#what-is-scroll) - [How Scroll Works](#how-scroll-works) - [Scroll Architecture](#scroll-architecture) - [Why Scroll Is EVM-Equivalent](#why-scroll-is-evm-equivalent) - [Benefits of Scroll](#benefits-of-scroll) - [Frequently Asked Questions](#faq) ## What Is Scroll? Scroll is an Ethereum Layer 2 scaling solution designed to improve transaction throughput without sacrificing decentralization or compatibility. Instead of executing every transaction directly on Ethereum, Scroll processes them off-chain and submits compressed cryptographic proofs to the Ethereum mainnet. Unlike many Layer 2 solutions that introduce modified execution environments, Scroll focuses on EVM equivalence, enabling developers to migrate existing Ethereum applications with little or no code changes. Its architecture is designed for decentralized applications across DeFi, gaming, NFTs, and enterprise Web3 services while maintaining the same developer experience as Ethereum. ## How Scroll Works Scroll combines zkRollup technology with Ethereum settlement. The transaction flow consists of four main stages: - **Users submit transactions to the Scroll network.** - **Transactions are executed off-chain by Scroll.** - **Multiple transactions are bundled into a batch and verified using zero-knowledge proofs.** - **The proof is submitted to Ethereum, where the batch is finalized and secured.** Because Ethereum verifies only the cryptographic proof instead of every transaction individually, the network achieves significantly lower costs and higher throughput. ## Scroll Architecture Scroll consists of several core components working together: ### Sequencer The Sequencer receives user transactions, orders them, and creates transaction batches before execution. ### zk Prover The Prover generates zero-knowledge validity proofs that mathematically verify every executed transaction without revealing unnecessary computation. ### Rollup Smart Contracts Smart contracts deployed on Ethereum verify zk proofs and finalize transaction batches on the Ethereum mainnet. ### Ethereum Settlement Layer Ethereum remains the final source of security, consensus, and data availability for Scroll. ## Why Scroll Is EVM-Equivalent One of Scroll's defining features is full EVM equivalence. Unlike many scaling networks that require modified virtual machines or custom developer tools, Scroll reproduces Ethereum's execution environment as closely as possible. Developers benefit from: - **Native Solidity support** - **Existing Ethereum smart contracts** - **Standard Ethereum wallets** - **Hardhat and Foundry compatibility** - **Existing Ethereum development libraries** - **Familiar debugging and testing workflows** This minimizes migration effort while preserving compatibility across the Ethereum ecosystem. ## Benefits of Scroll - **Lower Transaction Fees:** Batching transactions dramatically reduces gas costs compared to Ethereum mainnet. - **Ethereum-Level Security:** Every batch is verified on Ethereum through zero-knowledge proofs rather than independent validator assumptions. - **Faster Transactions:** Off-chain execution enables much higher throughput while maintaining rapid confirmation times. - **Seamless Developer Experience:** Ethereum developers can deploy existing applications with minimal modifications thanks to Scroll's EVM-equivalent architecture. - **Broad Web3 Compatibility:** Scroll supports DeFi protocols, NFT marketplaces, DAOs, gaming applications, infrastructure services, and enterprise blockchain solutions. _This content is for informational and educational purposes only and does not constitute financial, investment, or legal advice._ ## Frequently Asked Questions ### What is Scroll? Scroll is a zkEVM Layer 2 blockchain that scales Ethereum using zero-knowledge rollups while maintaining full EVM compatibility. ### How does Scroll improve Ethereum scalability? Scroll executes transactions off-chain, batches them together, generates zero-knowledge proofs, and submits those proofs to Ethereum for final settlement. ### What makes Scroll different from other Layer 2 networks? Its primary advantage is EVM equivalence, allowing Ethereum applications to run without rewriting smart contracts. ### Is Scroll compatible with Ethereum tools? Yes. Scroll supports Solidity, MetaMask, Hardhat, Foundry, Remix, and most Ethereum development infrastructure. ### What applications can be built on Scroll? Scroll supports decentralized exchanges, lending platforms, NFT marketplaces, blockchain games, payment applications, DAO infrastructure, and other Ethereum-compatible dApps.
