Starknet is a permissionless decentralized ZK-Rollup operating as an L2 network over Ethereum, where any dApp can achieve unlimited scale for its computation, without compromising Ethereum's composability and security. Starknet achieves scale, while preserving the security of L1 Ethereum by producing STARK proofs off-chain, and verifying those proofs on-chain. On Starknet, developers can easily deploy any business logic using Starknet Contracts. Starknet will provide Ethereum-level composability, facilitating easy development and compounding innovation. The STARK Prover powers the StarkEx scalability engine, and has already demonstrated the ability to process 600K transactions in a single proof on Mainnet.

The only Ethereum L2 with native yield for ETH and stablecoins. Blast yield comes from ETH staking and RWA protocols. The yield from these decentralized protocols is passed back to Blast users automatically. The default interest rate on other L2s is 0%. Our goal as contributors is to grow the on-chain economy with the highest-yield L2 possible. Community members who join our mission will have the opportunity to earn the Blast Airdrop. Blast only became possible this year following Ethereum's Shanghai upgrade. ETH yield from L1 staking, initially Lido, is automatically transferred to users via rebasing ETH on the L2.

Scroll is designed by and for Ethereum developers. A swift, reliable and scalable Layer 2 blockchain, Scroll extends Ethereum's capabilities, enabling apps to scale without any surprises. Thanks to bytecode-level compatibility, existing Ethereum apps can migrate onto Scroll as-is, and at a significantly reduced cost. Our open development approach combines the best ideas among value-aligned contributors and leads to more secure and better-designed systems. Scroll is forging a community-driven path to redefine and evolve Ethereum’s roadmap. Scroll uses advanced zero-knowledge-proof technology, battle-tested EVM models, and rigorous audits to ensure that our foundation is rooted in security and reliability. By prioritizing code security through open source collaboration, Scroll protects our developers and users against vulnerabilities.

Unichain is a DeFi-native Ethereum L2, optimized to be the home for liquidity across chains. Unichain is a decentralized finance (DeFi) platform designed as an Ethereum Layer 2 solution, focused on liquidity and cost efficiency. It offers faster, cheaper transactions with 1-second block times and aims to reduce transaction fees by 20x compared to Ethereum. Built on the OP Stack, it promotes scalability, open-source innovations, and future enhancements like Provable Block Building. Unichain targets developers and users in the DeFi space, providing resources for smart contract deployment and liquidity pool creation​. Informed by our experience building the world's largest decentralized trading protocol. Unichain is built on the OP stack. Technical innovations introduced by Unichain are open source, and available for any rollup to adopt. A network of full nodes monitors and verifies the actions of the sequencer, bringing faster transactions and more decentralization to Unichain.

Polygon is a leading blockchain infrastructure designed to bring the speed, scalability, and efficiency of the internet to global finance. With over 5 billion transactions, 117 million active addresses, and a 99.99% uptime record, Polygon has become the trusted foundation for real-time payments, stablecoin transfers, and decentralized finance. The network enables instant settlement at near-zero cost, powering billions in digital asset movement worldwide. Its enterprise-ready infrastructure includes built-in wallets, onramps, and compliance tools that simplify blockchain adoption for businesses. Powered by POL, Polygon’s native token fuels transactions, staking, and security across its multi-chain ecosystem. Built for scalability, Polygon delivers the reliability and performance that modern financial systems demand.

The new scalability stack for Ethereum. Instant transactions and scalable smart contracts. Optimism is a Public Benefit Corporation (PBC): a for-profit corporation intended to produce a public benefit and operate in a responsible and sustainable manner. This means that we are obligated to balance the pecuniary interests of our stockholders with the best interests of those materially affected by our conduct, as well as a specific "public benefit charter" we incorporated with. The specific public benefit purpose of the Company is to enhance and enshrine fair access to public goods on the internet through the development of open source software. This charter represents our pledge to the Ethereum community to uphold its values by producing infrastructure which promotes the growth and sustainability of an ecosystem of public goods.

zkSync is Ethereum’s most user-centric ZK rollup. Unlike any other scaling approach, ZK rollup has no upper bound on the value it can securely handle in L2. Unlike optimistic rollups, all assets can be moved capital-efficiently and fast between ZK rollup and L1. zkSync has the lowest real tx costs across all existing and planned rollups. zkSync also supports meta-transactions, instant confirmations with economic finality, low-cost privacy, and more. Ease and fun of development are at the core of zkSync design. Integrate payments and atomic swaps in a few lines of code. Develop type-safe, functional style smart contracts on Zinc: a Rust-based framework. Deploy your existing EVM codebase with minimum modifications.

Next generation layer 2 for Ethereum dApps. Use your favorite tools and scale your dApp at the lowest cost. An aggregator plays the same role that a node plays in Ethereum. Client software can do remote procedure calls (RPCs) to an aggregator, using the standard API, to interact with an Arbitrum chain. The aggregator will then make calls to the EthBridge and produce transaction results to the client, just as an Ethereum node would. Most clients will use an aggregator to submit their transactions to an Arbitrum chain, although this is not required. There is no limit on how many aggregators can exist, nor on who can be an aggregator. To improve efficiency, aggregators will usually package together multiple client transactions into a single message to be submitted to the Arbitrum chain. Arbitrum also supports a privileged Sequencer that can order transactions and give low latency transaction receipts.
