List of the Top 3 Layer 2 Protocols for XDEFI Wallet in 2025

The latest advancements in layer 2 solutions for Ethereum dApps empower developers to leverage their preferred tools while effectively reducing the expenses associated with scaling their applications. Within this framework, an aggregator functions similarly to a node on Ethereum, allowing client software to execute remote procedure calls (RPCs) through a standardized API to interact with an Arbitrum chain. This aggregator plays a crucial role by transmitting these calls to the EthBridge and returning the results of transactions to the client, reflecting the behavior of a conventional Ethereum node. Although it's common for clients to route their transactions through an aggregator when engaging with an Arbitrum chain, this is not strictly necessary. The architecture permits an unlimited number of aggregators to be created, and there are no restrictions on who can act as an aggregator. To optimize processing efficiency, aggregators often merge several client transactions into a single submission to the Arbitrum chain. Moreover, the Arbitrum ecosystem includes a specialized Sequencer capable of organizing transactions, which leads to rapid transaction confirmations with minimal latency. This groundbreaking arrangement not only enhances overall throughput but also cultivates an adaptable environment where developers can explore and innovate without the constraints of high costs, ultimately promoting greater experimentation within the blockchain space. By providing such flexibility, layer 2 solutions are poised to significantly transform the landscape of decentralized applications.

Starknet operates as a decentralized ZK-Rollup on the Ethereum network, enabling permissionless access for any decentralized application (dApp) to achieve virtually limitless computational scale while ensuring the security and composability inherent to Ethereum. By creating STARK proofs off-chain and subsequently validating them on-chain, Starknet effectively enhances scalability while preserving the integrity of Ethereum's Layer 1. Developers have the flexibility to easily apply various business logic through Starknet Contracts, which supports Ethereum-level composability and simplifies the development process, thereby fostering innovation. The StarkEx scalability engine, powered by the STARK Prover, is capable of processing up to 600,000 transactions within a single proof on Mainnet, underscoring its exceptional efficiency and reliability. This unique blend of capabilities positions Starknet as an essential framework for the future of decentralized applications, paving the way for more advanced and innovative solutions in the blockchain ecosystem. As the demand for scalable solutions continues to grow, Starknet stands out as a critical player in shaping the landscape of decentralized technologies.

Polygon, which was previously referred to as Matic Network, is a comprehensive protocol and framework established for the development and interconnection of blockchain networks that are compatible with the Ethereum platform. Despite Ethereum being the favored choice for blockchain initiatives, it has its own set of limitations. Polygon effectively tackles these challenges by offering a straightforward method for deploying pre-configured blockchain networks with a single click, bolstered by a growing selection of modules that aid in the creation of tailored networks. Furthermore, Polygon includes an interoperability protocol that allows for the seamless transfer of messages between Ethereum and various other blockchain ecosystems, in addition to providing a modular and optional “security as a service” feature. Its adaptor modules significantly improve the interoperability of existing blockchain systems, simplifying their integration process. By combining the advantages of Ethereum with those provided by autonomous blockchains, Polygon delivers an attractive range of functionalities aimed specifically at developers. In essence, it is meticulously designed by developers to cater to the unique requirements of their peers, ensuring it aligns well with the evolving demands of the blockchain community while fostering innovation and collaboration within the space.
