zkEVM-based Layer-2 scaling for Ethereum

Overview

Scroll builds a Layer-2 scaling solution for Ethereum using a zkEVM, a type of zero-knowledge proof-based rollup. It batches many transactions off-chain and posts a cryptographic proof to Ethereum to verify them, increasing throughput and reducing gas fees. The key feature is bytecode-level EVM equivalence, which lets developers port existing Ethereum smart contracts and applications to Scroll without changing their code. This differentiates Scroll from other scaling options by prioritizing seamless developer migration and compatibility, backed by a focus on ZK proofs and reliable mainnet operation. The company generates revenue from network usage fees on its platform and targets developers building DeFi, gaming, and NFT apps. Scroll’s goal is to make Ethereum-based applications faster, cheaper, and easier to build, enabling broader adoption of decentralized technologies.

Scroll fixes bridge bug with emergency adjustment.

Scroll fixes bridge bug with emergency adjustment. Bug could allow improper withdrawal of funds, and the fix was made without the former independent security council 11/11/2026 Scroll reported that it applied an emergency fix for a serious flaw in a contract on its bridge, an issue that could have allowed the improper withdrawal of funds. According to the project, no one exploited the bug before the update. The vulnerability was in the ZkEvmVerifierPostFeynman contract, responsible for checking proofs used to publish new network states on Ethereum. In the post-mortem released on the governance forum, Scroll explained that the manual construction of a call to the Halo2 verifier opened room for deviation from the expected flow. In practice, if a proof started with four specific bytes, the call could be sent to a different function than the normal route. Since this function used values that an attacker could control, there would be a possibility of presenting an old and valid proof as if it were related to a new input. If that happened, the effect would be the recording on Ethereum of a fake state root and a fake withdraw root. Scroll said previous versions did not have this problem because their verifiers did not use a function selector, causing all calls to follow the normal path. With the fix, the contract began routing all calls through a single entry point. Thus, the core parameters stopped being defined by the proof itself and became fixed by the contract. The project thanked ethical hacker ZHOUCHUNGONG, who reported the flaw on November 3, one week before the fix was published. Scroll said there was no time for exploitation because an attack would require the permissioned role of prover or the so-called "enforced batch mode." This mode is only enabled after seven days without finalization, which, according to Scroll, did not happen. The team also reviewed 748 finalizations made while the vulnerable contract was live and reproduced another 233 on a copy of the Ethereum mainnet, reaching the same roots. The episode stands out because it is the first emergency fix since the removal of Scroll's independent Security Council. In previous occasions, such as in May 2025 and February 2026, adjustments of this type went through approval by that council, which had 12 members and required agreement from 9 of them. The council was removed on June 1, 2026 and replaced by a 3-of-4 administrative multisig operated by the team. After that, Scroll lost its Stage 1 decentralization classification and now appears at Stage 0, according to L2Beat.

Kualitee & Kualitatem's Partnership with Scroll.io is Empowering the Next Wave of Founders

Kualitee & Kualitatem's partnership with Scroll.io is empowering the next wave of founders. * January 29, 2026 * Zunnoor Zafar * * Partnership Founders and developers are often forced to make a difficult choice: Speed or Stability? Innovation moves at lightning speed, but one minor bug in a smart contract or a glitch in a decentralised application (dApp) can mean the difference between a successful launch and a catastrophic setback. At Kualitee and Kualitatem, we believe you shouldn't have to choose. We are thrilled to announce our strategic partnership with Scroll.io, the bytecode-equivalent zkEVM rollup, scaling the future of Ethereum. This collaboration isn't just about technical integration. It's a commitment to the tech community and the founders who are building the "Open Economy." A partnership built for the "community-first" zkEVM. Scroll's mission is to build an open economy, which is a place where anyone, regardless of location, can innovate without boundaries. They have proven this commitment through massive community initiatives: * The Scroll Open Journey: A global hub for creation that transforms builders into pioneers through 6-week immersive tracks in DeFi, RWA, and Payments. * Regional Local Nodes: From Brazil to Kenya, Scroll is empowering local leaders through the Msingi | Daraja | Vuka pipeline, guiding founders from ideation (Msingi) to bridge-building (Daraja) and finally to market integration (Vuka). * Community Grants & Security Subsidies: With programs like the Security Subsidy Program in collaboration with Areta and Immunefi, Scroll is ensuring that even early-stage startups have access to elite security audits. At Kualitee and Kualitatem, we are stepping in to amplify these efforts. We aren't just joining an ecosystem; we are joining a global community of "mages" and "pioneers." A triple-threat to friction.
