Best Layer 2 Protocols for MetaMask

Meter is a high-performance infrastructure that allows smart contract to scale and travel seamlessly across heterogeneous blockchain networks. Meter is a Layer 1 or Layer 2 blockchain protocol. The Meter system consists two tokens: MTRG (the governance token; eMTRG is an ERC20 version) and MTR (the low-volatility currency to token). Financial assets should be able to flow freely between blockchains. Meter's HotStuff-based consensus permits 1000s of validator nosdes, making it the most decentralized Layer 2 Ethereum. Meter processes thousands upon thousands of transactions per second, and transactions are confirmed almost immediately. Meter Passport allows assets, smart contracts and smart contracts to travel and communicate across heterogeneous Blockchains for the best price and liquidity. Meter is an Ethereum compatible with unique enhancements. Meter is a Layer 2 DEX that is front-running/MEV resistant and fast.

Loopring is an open protocol that allows you to build scalable, non-custodial Ethereum exchanges. It leverages zero-knowledge proofs, zkRollup, to allow high-performance trading (high throughput and low settlement cost), without compromising Ethereum-level security guarantees. Throughout the trade lifecycle, users always have 100% control over their assets. Loopring allows you to trade on it. Loopring is an open-sourced and audited non-custodial exchange protocol. This means that no one in the Loopring ecosystem has to trust anyone else. With 100% Ethereum-level security guarantees, cryptoassets can be managed by users. Loopring is a highly scalable, decentralized exchange that batch-processes thousands of requests off-chain. This allows for verifiable correct execution via ZKPs. The performance of the underlying blockchains are no longer the bottleneck. Loopring is able to perform most operations, including order matching and trade settlement, using the Ethereum blockchain.

Open source community dedicated towards scaling Bitcoin, particularly its proof-of work security, in order to meet global needs, and emerging use cases while staying as close to Bitcoin's original ideas as possible. Syscoin has evolved over ten years on the mainnet and the foresight in its design gives it an advantage. It provides a comprehensive network for projects that aim to achieve Bitcoin L2. Syscoin, a mainnet Bitcoin L2, provides a data-availability protocol that scales. This makes EVM and AltVM rollsups possible on Bitcoin. Syscoin, which is merge-mined using a majority of Bitcoin hash rate to anchor rollups with Bitcoin's proof-ofwork, works with the existing sequencer architectures for rollups. Syscoin gives Bitcoin a scalable data layer that is required for rollups and other EVM or AltVM to tap into Bitcoin’s network in a secure and scalable manner.

Polkadot, a blockchain network, is being built to enable Web3.0. This will allow users to control their data and ensure that markets benefit from network efficiency. Gavin Wood, a former co-founder and CTO at Ethereum, founded Polkadot in 2016. Polkadot's technology solves the major problems that have hindered blockchain adoption over the past few years. Parity Technologies created Polkadot's Substrate software development toolkit that allows blockchain developers to create their own custom, fit for use blockchains. Polkadot allows multiple blockchains to communicate with each other, allows for easy upgrades, and introduces "shared Security", a plug and play network security model that allows developers focus on the technology instead of spending time and resources recruiting operators to run a new Blockchain.

Celer Network is a layer-2 scale platform that provides fast, secure, and low-cost applications on Ethereum, Polkadot, and other blockchains for mass adoption. Celer created the first generalized state channel network in the world and continues to push the boundaries of layer2 scaling using advanced Rollup technology. Core applications and middlewares such as cBridge, Layer2.finance, and many more ecosystem applications built on Celer, have attracted larger audiences in DeFi and blockchain interoperability. Layer2.finance addresses the two biggest obstacles to DeFi's mass adoption: the extremely high transaction fees and the difficulty of using and navigating the platform. cBridge, a multi-chain network, allows instant, low-cost, ANY-to-ANY value transfers between and within Ethereum's layer-2 chains. This includes Ethereum main chain, as well as other layer-1s and layer-2s.

Loom Network gives developers the flexibility and usability to create high-performance, user-facing dapps. Loom Network allows you to future-proof your app by deploying once to Loom. It integrates seamlessly to Bitcoin, Ethereum and Binance Chain. Loom Network is a multichain interop system that has been in production since early 2018. The network is optimized for scaling high-performance apps that require a smooth user experience. It allows dapps offer a UX comparable with traditional applications and onboard new customers without the need to download crypto wallet software. Developers can integrate assets from all major blockchains, and also create a dapp once and make it available to all users across all platforms. Developers can also use the token to pay for Loom Network dapp hosting. Developers pay a flat monthly fee to host dapps on Loom, which is different from Ethereum.

Every day, millions of transactions are being conducted on blockchain. However, people must expose their personal privacy as anyone with access to your address can see your entire financial history. Suterusu created a universal layer-2 privacy-protection protocol that is trustless and universal. Suter Shield links the sender address and the receiver address. This will give you complete protection for your transaction data using advanced cryptography. Layer-1 sender and receiver addresses are delinked. Layer-2 provides complete privacy protection for both user identities as well as transaction details. We designed and integrated a ZK-ConSNARK scheme that is almost constant in size, efficient proof generation, and verification.

Substrate allows you to create Ethereum-compatible smart contract in popular programming languages and run them much more quickly. Open source, decentralized business model that is funded by developer treasuries from participating blockchains. ParaState's Ewasm VM, or the Parallel SSVM, will work with all existing Ethereum smart contract without any modifications. ParaState supports 20+ programming languages that allow developers to create Ethereum-compatible smart contract. There are many examples, including generic programming languages like Solidity, Fe and Rust and JavaScript. Also, there are domain-specific languages (DSLs), such as MOVE and DeepSEA. Substrate-based Blockchains like Polkadot parachains already have a higher TPS (transactions/second) than Ethereum. Compute performance is more important than throughput for a smart contract platform. ParaState is a great platform for smart contracts.
