It utilizes [zero-knowledge (ZK) rollup](https://iq.wiki/wiki/zk-rollup) technology to achieve scalability by executing transactions off-chain, batching them, and verifying these batches on [Ethereum](https://iq.wiki/wiki/ethereum) using [ZK proofs](https://iq.wiki/wiki/zero-knowledge-proofs-zkps). Abstract aims to enhance the user experience through seamless onboarding, improved app discoverability, and a cohesive ecosystem.\n\nIt is developed through collaboration between Cube Labs, the [Pudgy Penguins](https://iq.wiki/wiki/pudgy-penguins) team, and Frame. Co-invented by [blockchain](https://iq.wiki/wiki/blockchain) entrepreneurs Michael Lee, [Luca Netz](https://iq.wiki/wiki/luca-netz), and Lorenzo Melendez, Abstract is engineered by [web3](https://iq.wiki/wiki/web3) developers Cygaar, 0xbeans, and stinkypablo. The network emphasizes community and cultural relevance, seeking to bridge the gap between [cryptocurrency](https://iq.wiki/wiki/cryptocurrency) and mainstream adoption. \n\nBy prioritizing user-friendly experiences and leveraging cutting-edge ZK cryptography, Abstract plans to create an accessible environment for a broader audience, while being fully [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm)-compatible to facilitate the integration of existing [Ethereum](https://iq.wiki/wiki/ethereum) applications.[\\[1\\]](#cite-id-p8xauexs34)​[\\[3\\]](#cite-id-w2wjhudsbcc)​[\\[4\\]](#cite-id-dmjjzq91dpm)​[\\[14\\]](#cite-id-bpdsfzpj6f)​[\\[15\\]](#cite-id-9cwthjt78i4)​\n\n## Wind-down of the Network\n\nIn October 2026, Abstract announced that it would wind down its network and cease operations.[\\[21\\]](#cite-id-2128nr0isy)​[\\[22\\]](#cite-id-ijbrb8nhc7) The team stated that the chain is scheduled to shut down on December 15, 2026, marking the end of nearly three years of development and operation.[\\[22\\]](#cite-id-ijbrb8nhc7)​\n\nThe project’s announcement explained that holders of assets on Abstract are expected to move their funds off the chain using either the Migration Hub or the native bridge before the shutdown date, after which unbridged funds will be inaccessible.[\\[21\\]](#cite-id-2128nr0isy)​[\\[22\\]](#cite-id-ijbrb8nhc7) \n\nAbstract’s engineering and ecosystem teams indicated that they would work with applications built on the network to migrate to other [blockchains](https://iq.wiki/wiki/blockchain).[\\[21\\]](#cite-id-2128nr0isy)​\n\nAbstract and its parent company Igloo attributed the decision to an unsustainable consumer-crypto-focused business model, thin liquidity, minimal institutional participation, and an inability to reach sustainable product-market fit.[\\[21\\]](#cite-id-2128nr0isy)​[\\[22\\]](#cite-id-ijbrb8nhc7) \n\nThis outcome followed the deployment of more than 144 applications on the chain, the onboarding of over 400,000 users, and partnerships with major brands such as Red Bull Racing and Disney.[\\[21\\]](#cite-id-2128nr0isy)​[\\[22\\]](#cite-id-ijbrb8nhc7)​\n\n## Products\n\n### Panoramic Governance\n\nAbstract Chain features [Panoramic Governance (PG)](https://iq.wiki/wiki/panoramic-governance-pg), a mechanism designed to align the interests of users, applications, and chain operators. PG addresses the misalignment often found in [Layer 2](https://iq.wiki/wiki/layer-2) [blockchains](https://iq.wiki/wiki/blockchain) through two interconnected systems: one that rewards governance participants and another that incentivizes app builders.\n\nThe first system aims to distribute sequencer fees to governance participants based on user engagement, while the second allows them to allocate token emissions to applications that provide value. PG seeks to enhance collaboration within the ecosystem and applies to any [L2](https://iq.wiki/wiki/layer-2) [blockchain](https://iq.wiki/wiki/blockchain) incorporating a [governance token](https://iq.wiki/wiki/governance-tokens) and sequencing capabilities.[\\[10\\]](#cite-id-6x57qnu82u9)​[\\[11\\]](#cite-id-3izswrtxvma)​\n\n![GaMWQ7qWEAAnmKw.jpeg](https://ipfs.everipedia.org/ipfs/QmVotRAcUnJv1GAdYLBBbDYibyVj58AuUZkod5UZRTUofW \"GaMWQ7qWEAAnmKw.jpeg\")\n\n### Abstract Global Wallet\n\nAbstract Chain offers the Abstract Global Wallet (AGW), which aims to facilitate cross-application interaction through native account abstraction. Users can create an account using methods such as email or social accounts.\n\nThe AGW creation process involves generating an externally owned account (EOA) during sign-up, followed by deploying a [smart contract ](https://iq.wiki/wiki/smart-contract)wallet that includes the EOA as an authorized signer. Key features include support for multiple signers, account recovery options, and transaction fee sponsorship. The wallet employs Shamir’s Secret Sharing, requiring two out of three key shards for access, thereby aiming to enhance security and flexibility within the ecosystem.[\\[12\\]](#cite-id-ybrrcdvm7b8)​[\\[13\\]](#cite-id-yuf378o03u)​\n\n[YOUTUBE@VID](P5lvuBcmisU)\n\n## Architecture\n\n### Layer 2\n\nAbstract Chain functions as a [Layer 2](https://iq.wiki/wiki/layer-2) [blockchain](https://iq.wiki/wiki/blockchain) on [Ethereum](https://iq.wiki/wiki/ethereum), aiming to improve transaction speed and reduce costs by leveraging [Ethereum’s](https://iq.wiki/wiki/ethereum) security framework. As a[ ZK Rollup](https://iq.wiki/wiki/zk-rollup) built with the ZK Stack, it batches and verifies transactions on [Ethereum](https://iq.wiki/wiki/ethereum) using [zero-knowledge proofs](https://iq.wiki/wiki/zero-knowledge-proofs-zkps), which seeks to enhance efficiency while maintaining security.[\\[5\\]](#cite-id-amo28axuqqs)​\n\n### Transaction Lifecycle\n\nAbstract Chain processes transactions in four phases, utilizing off-chain components and [smart contracts](https://iq.wiki/wiki/smart-contract) on [Layer 1 (L1)](https://iq.wiki/wiki/layer-1) and [Layer 2 (L2)](https://iq.wiki/wiki/layer-2) to ensure security:\n\n1. **Execution**: The transaction is executed, and the sequencer aims to create a batch.\n2. **Commitment**: Batches are committed to [Ethereum](https://iq.wiki/wiki/ethereum) as a state diff through the commitBatches function.\n3. **Validation**: A [zero-knowledge proof](https://iq.wiki/wiki/zero-knowledge-proofs-zkps) is generated off-chain and aims to be verified on the [L1](https://iq.wiki/wiki/layer-1) rollup contract.\n4. **Finalization**: The state is finalized on [Ethereum](https://iq.wiki/wiki/ethereum) by executing the executeBatches function, which saves the [Merkle tree](https://iq.wiki/wiki/merkle-tree) with [L2](https://iq.wiki/wiki/layer-2) logs.[\\[6\\]](#cite-id-33yf7ipcruo)\n\n### Sequencer\n\nThe sequencer in Abstract aims to manage [Layer 2](https://iq.wiki/wiki/layer-2) transactions by receiving, processing, and organizing them into batches for submission to [Ethereum](https://iq.wiki/wiki/ethereum). It features an RPC that provides an [API](https://iq.wiki/wiki/apis) for client interactions through HTTP and WebSocket for real-time updates.\n\nFurthermore, the [ETH](https://iq.wiki/wiki/ether-eth) Operator monitors [Layer 1](https://iq.wiki/wiki/layer-1) for events and batches multiple [Layer 2](https://iq.wiki/wiki/layer-2) transactions for dispatch to [Layer 1](https://iq.wiki/wiki/layer-1), ensuring secure and efficient processing.[\\[7\\]](#cite-id-3jfpu0x6ktf)​\n\n### Prover and Verifier\n\nThe prover and verifier components of Abstract use [zero-knowledge (ZK) proofs](https://iq.wiki/wiki/zero-knowledge-proofs-zkps) to validate transaction batches. An off-chain prover generates a[ ZK proof](https://iq.wiki/wiki/zero-knowledge-proofs-zkps), which is then verified by an on-chain verifier in the [Layer 1 (L1)](https://iq.wiki/wiki/layer-1) rollup contract.\n\nThe process includes collecting witness data, executing circuits to create the proof, and compressing it into a [ZK-SNARK](https://iq.wiki/wiki/zk-snark) for efficient verification on [Ethereum](https://iq.wiki/wiki/ethereum). This ensures transaction validity while leveraging [Ethereum's](https://iq.wiki/wiki/ethereum) security.[\\[8\\]](#cite-id-45hslpqm2io)​\n\n### L1 Rollup Contracts\n\nThe [L1](https://iq.wiki/wiki/layer-1) rollup contracts of Abstract Chain consist of [smart contracts](https://iq.wiki/wiki/smart-contract) deployed on [Ethereum](https://iq.wiki/wiki/ethereum) that aim to secure and verify the state of the [Layer 2 (L2)](https://iq.wiki/wiki/layer-2) network. They inherit [Ethereum's](https://iq.wiki/wiki/ethereum) security properties by storing state diffs, verifying validity proofs submitted by the [L2](https://iq.wiki/wiki/layer-2), and facilitating communication between [Layer 1](https://iq.wiki/wiki/layer-1) and [Layer 2](https://iq.wiki/wiki/layer-2) for cross-chain messaging and bridging.[\\[9\\]](#cite-id-zst3porqp)​\n\n## Funding\n\nIn July 2024, Igloo Inc., the parent company of [Pudgy Penguins](https://iq.wiki/wiki/pudgy-penguins), secured over $11 million in funding, primarily from Founders Fund, with additional contributions from [Fenbushi Capital](https://iq.wiki/wiki/fenbushi-capital), 1kx, [Everest](https://iq.wiki/wiki/everest) Ventures Group, and Selini Capital. This funding aims to support the establishment of Cube Labs, which will focus on [blockchain](https://iq.wiki/wiki/blockchain) research and development, especially Abstract.[\\[14\\]](#cite-id-bpdsfzpj6f)​\n\n## Partnerships\n\n### Abstract x Pyth\n\nAbstract aims to integrate with [Pyth Network](https://iq.wiki/wiki/pyth-network) to supply real-time financial market data for its [decentralized finance (DeFi)](https://iq.wiki/wiki/defi) applications. This partnership is intended to improve the accuracy and security of pricing information for more than 500 assets within protocols on Abstract, contributing to the functionality of its ecosystem.[\\[16\\]](#cite-id-mxygox5gi1e)​\n\n### Abstract x Quicknode\n\nAbstract integrates with QuickNode to establish a stable and scalable [blockchain](https://iq.wiki/wiki/blockchain) infrastructure. This collaboration seeks to improve the performance and reliability of applications on the Abstract platform.[\\[17\\]](#cite-id-lqkxwtkeato)​\n\n### Abstract x Reservoir\n\nAbstract aims to collaborate with [Reservoir](https://iq.wiki/wiki/reservoir) and its [Relay Protocol](https://iq.wiki/wiki/relay-protocol) to facilitate low-cost, instant bridging and swapping. This partnership also seeks to aggregate [NFT](https://iq.wiki/wiki/non-fungible-token-nft) liquidity and marketplaces, which may enhance user access to [NFT](https://iq.wiki/wiki/non-fungible-token-nft) resources.[\\[18\\]](#cite-id-op66iynsfm)​\n\n### Abstract x Dune\n\nAbstract seeks to integrate with [Dune](https://iq.wiki/wiki/dune) Analytics to offer real-time, customizable insights into on-chain activity, which may assist developers and users in visualizing and analyzing data within the platform.[\\[19\\]](#cite-id-nslao4287xp)​\n\n### Abstract x Goldsky\n\nAbstract aims to integrate with Goldsky to enhance data indexing, which will facilitate efficient querying of [blockchain](https://iq.wiki/wiki/blockchain) data and support the development of advanced applications.[\\[20\\]](#cite-id-g6kueyqhquq)​\n","summary":"Abstract was an Ethereum Layer 2 blockchain utilizing ZK rollups for scalable, low-fee transactions, enhancing user-friendly, consumer-focused applications.","categories":[{"id":"organizations","title":"Organizations"}],"promoted":0,"tags":[{"id":"Ethereum"},{"id":"Blockchains"}],"metadata":[{"id":"references","value":"[{\"id\":\"p8xauexs34\",\"url\":\"https://docs.abs.xyz/what-is-abstract\",\"description\":\"docs -
