Best Layer 2 Protocols for Bridge Wallet

The next-generation layer 2 solution for Ethereum decentralized applications (dApps) allows developers to leverage their preferred tools while achieving cost-effective scaling for their projects. In this ecosystem, an aggregator functions similarly to a node in the Ethereum network, enabling client software to perform remote procedure calls (RPCs) to interact with an Arbitrum chain via a standard API. Once a client makes a request, the aggregator interacts with the EthBridge to generate transaction results, akin to the operation of an Ethereum node. Although most clients will typically route their transaction submissions through an aggregator for efficiency, it is not a strict requirement for operation. There are no restrictions on the number of aggregators that can be established, nor on who is eligible to serve as one. To enhance processing efficiency, aggregators often consolidate several client transactions into a singular message for submission to the Arbitrum chain. Additionally, Arbitrum features a specialized Sequencer that has the capability to prioritize transaction ordering and provide rapid transaction receipts, further optimizing the user experience. This innovative structure opens up new possibilities for developers looking to enhance their dApps on Ethereum.

Polygon is the global leader in blockchain scalability solutions, offering an advanced infrastructure that transforms how money and data move across the internet. Purpose-built for real-time transactions, Polygon enables instant settlement, high throughput (1,000+ TPS), and transaction costs as low as $0.001. With over 5.3 billion transactions processed and $141 billion in transfer volume, it has become the backbone for digital payments, DeFi, and stablecoin ecosystems. Enterprises leverage Polygon’s robust framework to eliminate wire fees, improve liquidity, and ensure compliance—all while maintaining speed and transparency. The network’s aggregation layer, zkEVM, and AggLayer CDK provide developers with modular scalability for any use case—from tokenized assets (RWA) to cross-border payments. Its POL token secures the network and powers staking, governance, and utility functions. With account abstraction, social recovery, and seamless user onboarding, Polygon makes blockchain accessible to the masses. Backed by a thriving ecosystem and proven reliability, Polygon is redefining global payments and decentralized innovation at internet scale.

Ethereum's latest scalability framework ensures rapid transactions alongside efficient smart contracts. Optimism operates as a Public Benefit Corporation (PBC), which is a profit-driven entity established to create societal advantages while maintaining responsible and sustainable practices. This structure compels us to harmonize the financial interests of our shareholders with the welfare of individuals impacted by our actions, all while adhering to a specific "public benefit charter" we have adopted. The core mission of the Company is to improve and secure equitable access to internet public goods through the creation of open-source software. This charter embodies our commitment to the Ethereum community, as we strive to uphold its principles by developing infrastructure that fosters the growth and sustainability of a public goods ecosystem. In doing so, we aim not only to enhance technological innovation but also to cultivate an inclusive environment for all users.

RSK stands out as the most secure smart contract blockchain platform, benefiting from the robust protection of the Bitcoin Network. Recognized as a significant opportunity in decentralized finance (DeFi), RSK allows Bitcoin users to engage in lending, borrowing, trading, and earning interest on their holdings. The evolution of finance is clearly moving towards decentralization, with RSK leading the charge as the preeminent smart contract platform globally. The primary objective of RSK's Contracts is to enhance the Bitcoin Contracts ecosystem by facilitating smart contracts, enabling nearly instantaneous contract payments, and improving scalability. By utilizing Merged Mining and a two-way peg, RSK Blockchain establishes a seamless connection with Bitcoin, reinforcing its security and functionality. Furthermore, RIF, built on RSK, aspires to lay the foundational elements for a completely decentralized internet, fostering Decentralized Sharing Economies that empower individuals through enhanced identity management, payment solutions, storage options, communication channels, gateway services, and marketplace functionalities. This innovative approach not only protects individual value but also promotes a more equitable digital economy.

The Bitcoin Lightning Network enables immediate payments, providing rapid blockchain transactions without the delays typically associated with block confirmations. It enhances security through the use of smart contracts on the blockchain, eliminating the need for separate on-chain transactions for each payment. Users can experience transaction speeds ranging from milliseconds to mere seconds. This network boasts remarkable scalability, capable of handling millions to billions of transactions every second, far surpassing traditional payment systems in terms of capacity. Additionally, it allows payments to be linked to specific actions or clicks without the need for intermediaries. Cost efficiency is another benefit, as settling transactions off-chain results in substantially lower fees, paving the way for innovative applications like instant micropayments. Furthermore, the Lightning Network supports cross-chain atomic swaps that can be executed instantly and off-chain, provided the involved blockchains utilize the same cryptographic hash function. This interoperability between different blockchain systems opens up new possibilities for seamless financial interactions.
