Ethereum has long been the cornerstone of decentralized applications and smart contracts. However, as its popularity surged during the DeFi and NFT booms, so did its limitations—high gas fees, network congestion, and slow transaction speeds. Enter Scroll, a next-generation Layer 2 scaling solution designed to preserve Ethereum’s security and decentralization while dramatically improving performance.
This article dives deep into Scroll's architecture, ecosystem, and real-world utility, explaining how it enhances Ethereum’s scalability using cutting-edge zero-knowledge technology. Whether you're a developer, investor, or crypto enthusiast, you’ll gain a clear understanding of why Scroll matters in the evolving blockchain landscape.
The Origins of Scroll
In 2021, three visionary developers—Ye Zhang, Haichen Shen, and Sandy Peng—founded Scroll with a shared mission: to make Ethereum more scalable without compromising its core values.
Their motivation stemmed from firsthand experience during the 2020 DeFi explosion, when Ethereum’s network struggled under unprecedented demand. Transactions took hours to confirm, and gas fees skyrocketed—making small trades economically unviable.
Rather than sacrifice decentralization for speed, the team set out to build a scaling solution that would align perfectly with Ethereum’s principles. Their answer? A zkEVM-based Layer 2 rollup that executes transactions off-chain but verifies them on Ethereum using zero-knowledge proofs.

Core Vision and Values
Scroll isn't just about technology—it's built on a foundation of community-driven ideals.
Vision
- Create a decentralized computing platform accessible to everyone.
- Solve persistent issues like high gas fees and network bottlenecks.
- Empower global users by making blockchain interactions affordable, secure, and efficient.
- Scale Ethereum infinitely while preserving its trust model.
Values
- Community-Centric Development: Scroll builds transparently in public, inviting feedback and collaboration.
- Open Source & Transparency: All code is open-sourced, promoting trust and auditability.
- Decentralization First: From day one, Scroll prioritizes distributed control across nodes, provers, and sequencers.
These principles ensure that Scroll evolves as a truly decentralized ecosystem—not a corporate-controlled chain.
What Is Scroll?
At its core, Scroll is a zkEVM Layer 2 rollup for Ethereum. It processes transactions off the mainnet, then submits compressed data and cryptographic proofs back to Ethereum for final validation.
Think of it as a high-speed express lane running parallel to Ethereum’s congested highway. Traffic (transactions) moves faster and cheaper, but safety (security) is still enforced by the main road.
Using zero-knowledge proofs (zk-proofs), Scroll guarantees that every batch of transactions is valid without revealing individual details. This ensures privacy, efficiency, and full compatibility with Ethereum’s existing tooling—meaning most dApps can migrate with minimal changes.
The mainnet launched in October 2023 and continues to evolve toward full decentralization across all components.
Understanding Scroll’s Tri-Layer Architecture
Scroll’s robustness comes from its modular design. It operates through three distinct layers:
1. Settlement Layer (L1 – Ethereum)
This is where finality happens. Ethereum acts as the anchor:
- Hosts the rollup smart contract and bridge.
- Stores transaction data for data availability.
- Verifies validity proofs generated off-chain.
- Enables cross-chain messaging and asset transfers.
By relying on Ethereum for settlement, Scroll inherits its battle-tested security and decentralization.
2. Sequencing Layer (L2 – Off-Chain Execution)
This layer handles real-time transaction processing:
- Users submit transactions to the Sequencer.
- An Execution Node runs the zkEVM to process these transactions.
- A Rollup Node batches them into blocks, posts data to Ethereum, and forwards proofs for verification.
This setup allows thousands of transactions per second at a fraction of mainnet costs.
3. Proving Layer (zk-Proof Generation)
This is where cryptography shines:
- A decentralized pool of provers generates zk-SNARK proofs for each batch.
- A coordinator assigns tasks and collects completed proofs.
- These proofs are sent back to the Rollup Node for submission to Ethereum.
Once verified on-chain, the state update is finalized—securely and immutably.

How to Get Started with Scroll
Ready to explore Scroll? Here’s how to begin:
✅ Add Scroll Network to Your Wallet
You’ll need to configure your wallet (e.g., MetaMask) with Scroll’s RPC settings:
- Network Name: ScrollMainnet
- RPC URL:
https://rpc.scroll.io - Chain ID: 534352
- Currency Symbol: ETH
- Block Explorer: blockscout.scroll.io
Alternatively, visit chainlist.org, connect your wallet, search for “Scroll,” and auto-add the network with one click.
🔄 Bridge ETH to Scroll
To interact with dApps on Scroll, bridge ETH from Ethereum:
- Go to the official bridge: scroll.io/bridge
- Connect your wallet.
- Select “From: Ethereum” and “To: Scroll.”
- Enter the amount (leave some ETH on L1 for future gas).
- Approve and confirm the transaction.
Your funds will arrive on Scroll in minutes.
💡 Pro Tip: Always start with the native bridge when entering a new ecosystem—it’s safer and often eligible for future incentives or airdrops.
Exploring the Scroll Ecosystem
A growing number of dApps now support Scroll, spanning DeFi, NFTs, gaming, and identity solutions.
To discover what’s live:
- Visit scroll.io/ecosystem
- Check out protocols like SyncSwap (DEX), ScrollSwap, and lending platforms integrating native yield opportunities.
Engaging early helps you understand user flows, test interfaces, and potentially qualify for future token distributions.
Funding and Backing
Scroll has raised $80.5 million in funding across four rounds, with major backing from:
- Qiming Venture Partners
- Polychain Capital
- Bain Capital Crypto
- Robot Ventures
This strong financial foundation supports ongoing R&D, ecosystem growth, and decentralization efforts—including incentivizing independent prover participation.
Why Scroll Stands Out Among L2s
While many Layer 2 solutions exist (Optimism, Arbitrum, zkSync), Scroll differentiates itself through:
- True EVM Equivalence: Full compatibility with Ethereum tooling (Hardhat, Remix, etc.)
- No Trusted Setup: Uses transparent cryptographic methods requiring no initial trust assumptions.
- Progressive Decentralization: Actively working toward distributed proving and sequencing.
- Low Latency Bridging: Near-instant deposits and ~8-hour withdrawals (with potential for faster options via third parties).
Its focus on correctness and alignment with Ethereum’s roadmap makes it a compelling long-term player.
Frequently Asked Questions (FAQ)
Q: Is Scroll safe?
A: Yes. All transactions are verified by Ethereum via zero-knowledge proofs. Even if malicious actors control parts of the L2, they cannot steal funds or alter state without valid proofs.
Q: Do I need special tools to develop on Scroll?
A: No. Since it’s zkEVM-compatible, developers use standard Solidity tooling—no new languages or frameworks required.
Q: Can I get an airdrop from Scroll?
A: While not confirmed, many expect an airdrop based on usage patterns. Early interaction (bridging, swapping) may increase eligibility chances.
Q: How fast are transactions on Scroll?
A: Blocks are produced every few seconds. Finality occurs after proof verification on Ethereum (~minutes to hours depending on batch cycles).
Q: Are gas fees lower than Ethereum mainnet?
A: Significantly. Fees are typically 1–5% of L1 costs due to off-chain computation and data compression.
Q: What happens if the Sequencer goes down?
A: Users can still force transactions directly to L1 for eventual inclusion—a censorship-resistant fallback mechanism.
