Meter serves as a highly efficient infrastructure designed to enable smart contracts to scale and navigate effortlessly across diverse blockchain networks. Functioning as both a Layer 1 and Layer 2 blockchain protocol, Meter is built around two primary tokens: MTRG, which acts as the governance token (with eMTRG representing its ERC20 version), and MTR, designed to be a stable currency token. To facilitate the unrestricted movement of financial assets between blockchains, Meter employs a HotStuff-based consensus mechanism that supports thousands of validator nodes, positioning it as the most decentralized Layer 2 solution for Ethereum. With the capacity to process thousands of transactions every second, transactions on Meter are confirmed in nearly real time. Additionally, Meter Passport enables assets and smart contracts to traverse and interact across various blockchains, optimizing for price, liquidity, and yield. Meter stands out as an Ethereum-compatible platform enhanced with distinctive features. In contrast to other Layer 2 solutions, decentralized exchanges (DEXes) built on Meter are resistant to front running and miner extractable value (MEV) issues, ensuring they are both swift and censorship-resistant. This combination of capabilities makes Meter a formidable player in the blockchain ecosystem.

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.
