Best Layer 2 Protocols for BNB Smart Chain (BSC)

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.

COMBO is a leader in scaling solutions for Web3 games. COMBO builds an open-source, decentralized protocol for games that is accessible to all by leveraging the top game engine in the world. It aims at maximising the potential of Web3-based games by connecting developers with the ecosystem in a secure, efficient, and affordable way. COMBO has formed partnerships with the leading Web3 infrastructure projects in order to provide comprehensive development tools and integrated game engines. These advanced tools will help game developers easily enter the Web3 world and simplify and speed up their game development processes. By using optimistic rollup we can achieve 5,000 TPS and keep the gas price as low as 0.000000008 Gwei. COMBO has established full-fledged partnership with leading Web3 Infrastructure projects to provide comprehensive toolchains for development and built-in games engines.

Carbon is a cross-chain protocol which acts as a building block to DeFi. Anyone can bootstrap open financial markets on any blockchain, for any asset type, using the Carbon protocol. Carbon powers Demex, a popular and fully decentralized exchange that allows trading of a wide range of financial instruments. Interoperable between blockchains such as Ethereum, Cosmos and BSC. It also powers the PolyNetwork bridge, which allows for true cross-chain liquidity pools. Any DeFi innovation is supported with native support for crypto derivatives, Balancer style liquidity pools, AMMs and on-chain orders books. Cosmos-SDK custom-built and secured by a large network validators through Tendermint PoS to ensure trustless and secure transactions.

Raydius is a middleware platform that aims to connect the blockchain ecosystem. Building cross-chain applications can be difficult due to the different layer 1 and 2 protocols that support different development frameworks. Raydius addresses this problem by providing cross-layer support for developers, so they can concentrate on creating the products that users need. Raydius provides an EVM compatible layer 2-POS side chain on Substrate. It connects to different layer 1 or layer 2 blockchains via bi-directional bridges. Cross-chain bridge aggregators are available to provide a single-stop solution for users who want to use dApps from different chains. Raydius bridge aggregator connects to popular asset bridges such as multichain.xyz and Matic to provide the best routing possible for users who want to switch assets between blockchains.

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.

Blockchain-powered smart contracts cannot be accessed from the internet and are therefore isolated from the rest of the world. The smart contract's computation is also extremely expensive and limited in resource capacity. A Decentralized Oracle service supporting multiple heterogeneous blockchains. DOS Network provides real-world data, event, and computation power to smart contract in a secure and reliable way that is scalable, efficient, and scalable. Many scenarios, such as flight delay insurance, can be automatically indemnified by DOS Network by bringing externally insured events to the onchain insurance contract. To obtain reliable and verifiable price feeds for stablecoins or crypto derivatives, DOS Network must be used frequently. DOS Network allows crypto lending platforms to easily access token exchange rates, import borrower's social media data, and instantly determine interest rates.

Manta Pacific uses Celestia, a modified OP-stack and a modified OP-stack to deliver a cutting edge technical infrastructure that offers extraordinary scalability with low gas fees. Manta Pacific, in conjunction with its universal circuits and ZK applications, provides an unrivaled platform for developing and deploying dApps and ZK apps. Apps deployed on Manta deliver the best user experience and value, from DeFi to gaming to Social. The Manta grants program is designed for users to explore and grow valuable use cases that solve real-world pain points. Manta Network’s zkSBTs enable users to verify without revealing any details in a decentralized, trustless manner. zkSBTs, such as the zkBAB or zkGalxe Passports, provide a seamless KYC verification on-chain without the need to scan passports and enter sensitive personal information.

opBNB, a high-performance layer-2 within the BNB eco-system, is built using the OP stack. Gas fees for opBNB are stable and low-cost thanks to its block size of a 100M. This makes it a great choice for adoption in multiple digital environments. opBNB is able to meet a wide range of needs, including gaming, decentralized exchanges, daily use and digital collectibles. It also delivers optimal performance. Gamers are used to highly responsive experiences. Imagine looting a game asset after completing an entire combat scenario. Then, having to wait for the game to respond to grant you the item. A game like that would be unappealing to play and frustrating.
