Best Layer 2 Protocols for Axelar

Next generation layer 2 for Ethereum DApps. Scale your dApp with your favorite tools at the lowest possible cost. An aggregator is the same role as a node in Ethereum. Client software can make remote procedure calls (RPCs), to an aggregator using the standard API to interact with an Arbitrum network. The aggregator will then call the EthBridge to produce transaction results to the client just like an Ethereum node. Although it is common for clients to use an aggregator to submit transactions to an Arbitrum Chain, this is not mandatory. There is no limit to the number of aggregators that can exist or who can be an aggregater. In order to improve efficiency, aggregators often combine multiple client transactions into one message that can be submitted to Arbitrum. Arbitrum also supports a privileged Sequencer, which can order transactions and provide low latency transaction receipts.

Scroll was designed by and for Ethereum Developers. Scroll is a fast, reliable, and scalable Layer 2 Blockchain that extends Ethereum capabilities. This allows apps to scale without surprises. Existing Ethereum apps can be migrated to Scroll at a significant cost reduction thanks to bytecode compatibility. Our open-source development approach brings together the best ideas from contributors who share similar values, resulting in more secure and better designed systems. Scroll is a community-driven initiative that redefines and evolves Ethereum's roadmap. Scroll uses advanced EVM models that have been battle-tested, as well as rigorous audits, to ensure our foundation is rooted firmly in security and reliability. Scroll protects its developers and users from vulnerabilities by prioritizing code safety through open source collaboration.

Unichain is an Ethereum L2 optimized for DeFi, and designed to be the home of liquidity across chains. Unichain is an Ethereum Layer 2 platform that focuses on cost-efficiency and liquidity. It offers faster and cheaper transactions, with block times of just one second. It also aims to reduce transaction costs by 20x when compared to Ethereum. It is built on the OP Stack and promotes scalability. Open-source innovations are also promoted, as well as future enhancements such as Provable Block Building. Unichain is a resource for developers and users of the DeFi ecosystem, offering resources to deploy smart contracts and create liquidity pools. Our experience in building the largest decentralized trading platform in the world has informed our design. Unichain is based on the OP stack. Unichain's technical innovations are open source and available to any rollup. A network of full-nodes monitors and validates the actions of the Sequencer, bringing faster transactions to Unichain and more decentralization.

The new scalability stack to Ethereum. Instant transactions and scalable smart contract. Optimism (PBC) is a for-profit corporation that produces a public benefit while also operating in a responsible, sustainable manner. This means that we have to balance the stockholders' interests with the best interests for those who are most affected by our conduct. We also have a "public benefit charter" that we were incorporated with. The Company's specific public benefit purpose is to increase and enshrine fair internet access through the development open-source software. This charter is our promise to the Ethereum community that we will uphold its values and produce infrastructure that promotes the growth of an ecosystem of public good.
