{"id":"scroll","title":"Scroll","content":"**Scroll** is a scaling solution for [Ethereum](https://iq.wiki/wiki/ethereum) that aims to address scalability issues. It is a [Layer-2](https://iq.wiki/wiki/layer-2) solution built on the [zkEVM](https://iq.wiki/wiki/zkevm) (Zero-Knowledge [Ethereum Virtual Machine](https://iq.wiki/wiki/ethereum-virtual-machine-evm)), focusing on improving security and performance.[\\[1\\]](#cite-id-cjyupa7gklb)​\n\n## Overview\n\nFounded in 2021 by Haichen Shen, Sandy Peng, and Ye, Scroll is a [Layer-2](https://iq.wiki/wiki/layer-2) scaling solution for [Ethereum](https://iq.wiki/wiki/ethereum) that addresses scalability challenges. It utilizes [zkEVM](https://iq.wiki/wiki/zkevm) (Zero-Knowledge [Ethereum Virtual Machine](https://iq.wiki/wiki/ethereum-virtual-machine-evm)) technology to process transactions off-chain and then bundle them for verification on the [Ethereum](https://iq.wiki/wiki/ethereum) mainnet.\n\nLaunched in October 2023, the [Mainnet](https://iq.wiki/wiki/mainnet) aims to improve [Ethereum's](https://iq.wiki/wiki/ethereum) scalability by reducing transaction costs and increasing processing speed through zero-knowledge proofs. The system seeks to enhance [Ethereum's](https://iq.wiki/wiki/ethereum) capacity while maintaining its security and decentralization. As of February 2026, the network has processed over 110 million transactions and supports an ecosystem of over 100 decentralized applications (dApps) built by more than 700 active developers. The platform claims to maintain an average gas fee of less than $0.005 per transaction.[ \\[1\\]](#cite-id-cjyupa7gklb)​[\\[2\\]](#cite-id-hgg0xoooa7l)​[\\[12\\]](#cite-id-cZyrRIxz9OPljVGo)​[\\[3\\]](#cite-id-stbdl7vag8p)​[\\[4\\]](#cite-id-gbgb08pulsr)​[\\[13\\]](#cite-id-VVDsnZkOxm6KOutQ)​[\\[14\\]](#cite-id-Sv0F3Sdj45v9LAp0)​\n\n## Ecosystem\n\n### Scroll Sepolia Testnet\n\nThe Scroll Sepolia testnet operates on top of [Ethereum’s](https://iq.wiki/wiki/ethereum) Sepolia [Testnet](https://iq.wiki/wiki/testnet), with Sepolia serving as the base network and Scroll Sepolia as a zero-knowledge rollup layer. It features demo applications including a bridge, block explorer, and rollup explorer.\n\nScroll Sepolia is used for testing and evaluating changes before they are deployed to Scroll [Mainnet](https://iq.wiki/wiki/mainnet). It aims to provide a testing environment similar to the [mainnet](https://iq.wiki/wiki/mainnet), allowing for the assessment of upgrades and performance in a live setting.[\\[5\\]](#cite-id-l5tr77e5kyr)​[\\[6\\]](#cite-id-5dednba2ez)​\n\n### Partnerships and Programs\n\nScroll's ecosystem includes integrations with major DeFi and infrastructure protocols such as [Aave](https://iq.wiki/wiki/aave), Lido, [Circle](https://iq.wiki/wiki/circle), EtherFi, Mellow, and [Symbiotic](https://iq.wiki/wiki/symbiotic). To foster development, Scroll initiated \"Scroll Open,\" a six-week builder program featuring a $100,000 prize pool.[\\[14\\]](#cite-id-Sv0F3Sdj45v9LAp0)​\n\n## Products\n\n### Scroll Origins\n\nScroll Origins is an [NFT](https://iq.wiki/wiki/non-fungible-token-nft) program intended to recognize developers who deployed contracts on Scroll [Mainnet](https://iq.wiki/wiki/mainnet) within 60 days of the [Genesis Block](https://iq.wiki/wiki/genesis-block), ending December 9, 2023. Each [NFT](https://iq.wiki/wiki/non-fungible-token-nft) features a distinct polynomial design related to [zkEVM](https://iq.wiki/wiki/zkevm) technology, reflecting deployment details such as date and address.\n\nThe [NFTs](https://iq.wiki/wiki/non-fungible-token-nft) are categorized based on deployment timing: Quintic for the first 30 days, Quartic for days 30 to 45, and Cubic for days 45 to 60. These non-transferable [NFTs](https://iq.wiki/wiki/non-fungible-token-nft) were available for claiming on the Scroll website starting December 14, 2023.[\\[9\\]](#cite-id-4jggc8u8hdj)​[\\[10\\]](#cite-id-qw2qk1sl2x9)​\n\n### Scroll Canvas\n\nScroll Canvas aims to provide a platform for displaying on-chain credentials and achievements within the Scroll ecosystem using verified Badges. These non-transferable badges serve as proof of user participation and milestones and are linked to individual wallets.\n\nThe integration with the [Ethereum](https://iq.wiki/wiki/ethereum) Attestation Service ensures that each Badge is authentic and verifiable. Users can use Scroll Canvas to document their achievements, organize Badge collections, and access new opportunities. Builders can issue Badges to facilitate user engagement and recognition.\n\nAs an open-source platform, Scroll Canvas invites community contributions and development. Users can mint their Canvas with a small fee, with opportunities for discounts available through invite codes.[\\[11\\]](#cite-id-zk15a3rbb7d)​\n\n### Scroll Swap and Scroll Lend\n\nFollowing the acquisition of the DeFi project Honeypop in February 2026, Scroll launched its own native DeFi protocols to ensure stable, in-house infrastructure. These include Scroll Swap, an automated market maker (AMM) for trading, and Scroll Lend, a [Morpho](https://iq.wiki/wiki/morpho)-powered lending platform.[\\[15\\]](#cite-id-vT62rD4Letc9JfMb)​\n\n### USX Stablecoin\n\nThe Scroll ecosystem includes [USX](https://iq.wiki/wiki/usx), a private and gasless native stablecoin, and sUSX, a yield-bearing version of the stablecoin.[\\[15\\]](#cite-id-vT62rD4Letc9JfMb)​\n\n## Strategic Developments\n\n### Honeypop Acquisition\n\nOn February 16, 2026, Scroll acquired Honeypop, a [decentralized finance](https://iq.wiki/wiki/defi) (DeFi) project within its ecosystem. The acquisition was driven by a strategy to internalize core DeFi infrastructure, addressing the unreliability of some third-party protocols that became inactive after incentive programs ended. \n\nBy bringing the Honeypop team in-house, Scroll aims to guarantee the long-term stability of native services like automated market makers (AMMs) and lending platforms. This led to the creation of Scroll Swap and Scroll Lend.[\\[15\\]](#cite-id-vT62rD4Letc9JfMb)​\n\n## Architecture\n\nScroll’s architecture is organized into three layers:\n\nThe Settlement Layer utilizes [Ethereum](https://iq.wiki/wiki/ethereum) to provide data availability, ordering, and validity proof verification. It supports communication and asset transfers between [Ethereum](https://iq.wiki/wiki/ethereum) and Scroll by deploying necessary contracts on [Ethereum](https://iq.wiki/wiki/ethereum).\n\nThe Sequencing Layer includes an Execution [Node](https://iq.wiki/wiki/node) that processes transactions and generates [L2](https://iq.wiki/wiki/layer-2) blocks. It also contains a Rollup [Node](https://iq.wiki/wiki/node) that batches transactions, posts data to [Ethereum](https://iq.wiki/wiki/ethereum), and submits validity proofs for finality.\n\nThe Proving Layer is composed of provers that generate [zkEVM](https://iq.wiki/wiki/zkevm) validity proofs to verify [L2](https://iq.wiki/wiki/layer-2) transactions, with a coordinator managing the distribution of proving tasks and relaying proofs to the Rollup [Node](https://iq.wiki/wiki/node) for finalization on [Ethereum](https://iq.wiki/wiki/ethereum).\n\nThis layered structure aims to ensure efficient transaction processing and security within the Scroll network, utilizing [Ethereum’s](https://iq.wiki/wiki/ethereum) infrastructure for data and finality.[\\[7\\]](#cite-id-gjqtynx3vmp)​\n\n### Scroll Node\n\nThe Scroll node facilitates interaction with the network through three components:\n\nThe Sequencer processes [L2](https://iq.wiki/wiki/layer-2) transactions and generates new blocks, utilizing the [Go-Ethereum (Geth)](https://iq.wiki/wiki/geth) implementation for compatibility and security.\n\nThe Coordinator handles execution traces from the Sequencer and assigns proof generation tasks to Rollers.\n\nThe Relayer monitors the status of [L2](https://iq.wiki/wiki/layer-2) blocks and manages message relays for deposits and withdrawals between [Ethereum](https://iq.wiki/wiki/ethereum) and Scroll. This setup aims to support effective network operations and communication.[\\[8\\]](#cite-id-tbg8xzaist)​\n\n### Roller Network\n\nThe Roller Network consists of Rollers that generate validity proofs for the zkRollup. These Rollers use hardware accelerators, such as GPUs, FPGAs, and ASICs, to reduce proving time and costs.\n\nThe process involves converting execution traces from the Coordinator into circuit witnesses, creating proofs for each [zkEVM](https://iq.wiki/wiki/zkevm) circuit, and aggregating these proofs into a single block proof. This setup aims to enhance the efficiency and accuracy of proof generation.[\\[8\\]](#cite-id-tbg8xzaist)​\n\n### Rolllup and Bridge Contracts\n\nScroll interacts with [Ethereum](https://iq.wiki/wiki/ethereum) through Rollup and [Bridge](https://iq.wiki/wiki/bridge) smart contracts. The Rollup contract manages [L2](https://iq.wiki/wiki/layer-2) state roots and blocks, storing data on [Ethereum](https://iq.wiki/wiki/ethereum) to support data availability and security for Scroll blocks. It aims to finalize [L2](https://iq.wiki/wiki/layer-2) blocks on Scroll once block proofs are verified.\n\nThe [Bridge](https://iq.wiki/wiki/bridge) contracts enable the transfer of messages and assets between L1 and [L2](https://iq.wiki/wiki/layer-2). Users initiate these transfers through the [Bridge](https://iq.wiki/wiki/bridge) contract, with the Relayer indexing and processing transactions for inclusion in [L2](https://iq.wiki/wiki/layer-2) blocks and vice versa. This setup aims to facilitate communication and asset movement between the two layers.[\\[8\\]](#cite-id-tbg8xzaist)​\n\n## Governance\n\nScroll features a native governance token with the ticker SCR. The token allows holders to vote on proposals related to the protocol's development and governance, as described by the function \"Vote or propose on Scroll.\" [\\[14\\]](#cite-id-Sv0F3Sdj45v9LAp0)​\n\n## Funding\n\nScroll secured 80 million across two rounds. The lead investors in this round included [Polychain](https://iq.wiki/wiki/polychain-capital), Sequoia Capital China, and others. Scroll has 20 institutional investors and was valued at $1.8 billion as of March 7, 2023.[\\[13\\]](#cite-id-VVDsnZkOxm6KOutQ)​[\\[4\\]](#cite-id-gbgb08pulsr)​\n\nFollowing its acquisition of Honeypop in February 2026, Scroll announced a shift in its ecosystem funding strategy. The network plans to become more selective with its grants, prioritizing support for teams that demonstrate a long-term commitment to building within the Scroll ecosystem.[\\[15\\]](#cite-id-vT62rD4Letc9JfMb)​\n\n$$\n$$","summary":"Scroll is an Ethereum Layer-2 scaling solution using zkEVM to enhance scalability, reduce costs, and maintain security, launched in October 2023.","images":[{"id":"QmcSqzQgd2ftUNeXx8Z5iJc8Xs5k7z4X6vcXmRphadW4Ka","type":"image/jpeg, image/png"}],"categories":[{"id":"defi","title":"Decentralized Finance"}],"tags":[{"id":"Ethereum"},{"id":"Blockchains"}],"media":[{"id":"QmSoS4jPYi8RtJnFE8Y8uXqqamJkFT9oRYry32TqNDjy6v","size":"0.08","name":"Screenshot 2024-08-01 at 20.07.32.png","type":"GALLERY","source":"IPFS_IMG"},{"id":"QmTaNTT3ZkeHtMBGBZWsrbsmxMNBbopzbjG2jU98R2eZMd","size":"0.76","name":"Untitled--3-.png","type":"GALLERY","source":"IPFS_IMG"}],"metadata":[{"id":"website","value":"https://scroll.io"},{"id":"twitter_profile","value":"https://x.com/Scroll_ZKP"},{"id":"youtube_profile","value":"https://www.youtube.com/@Scroll_ZKP/featured"},{"id":"discord_profile","value":"https://discord.gg/scroll"},{"id":"github_profile","value":"https://github.com/scroll-tech"},{"id":"references","value":"[{\"id\":\"cjyupa7gklb\",\"url\":\"https://trustwallet.com/blog/beginners-guide-to-scroll\",\"description\":\"trustwallet -
