Best Layer 2 Protocols for Android

Loopring is an open protocol for building scalable non-custodial exchanges on Ethereum. Leveraging zero-knowledge proofs (zkRollup), it allows for high performance trading (high throughput, low settlement cost), without sacrificing Ethereum-level security guarantees. Users always maintain 100% control of their assets throughout the trade lifecycle. You can trade on Loopring to test it out. Loopring is an open-sourced, audited, and non-custodial exchange protocol, which means nobody in the Loopring ecosystem needs to trust others. Cryptoassets are always under users' own control, with 100% Ethereum-level security guarantees. Loopring powers highly scalable decentralized exchanges by batch-processing thousands of requests off-chain, with verifiably correct execution via ZKPs. The performance of underlying blockchains is no longer the bottleneck. Loopring performs most operations, including order-matching and trade settlement, off the Ethereum blockchain.

Private transactions are computed in seconds on all devices, and our rollup service saves gas and settles in minutes. Fund and manage your DeFi positions anonymously, and trade them inside the Aztec privacy shield. Program private money, escrow, money streaming, micropayments, your imagination is the limit.

Stake on Ethereum’s first private computer and earn. Staking with Keep is the best way to back a truly decentralized network and the future of DeFi. Privacy-focused infrastructure for the public blockchain. The Keep network allows private data to be used on public protocols without sacrificing confidentiality. Keep is the only protocol that is truly decentralized. “Keeps” are off-chain containers that allow contracts to use private data without exposing the data to the public blockchain. The Keep network stores data with the highest level of encryption. Keep and tBTC have been audited by the strongest firms in the ecosystem. Learn more about staking on the Keep network to earn rewards and secure the network. Keep is a privacy layer that enables private data to be leveraged on public blockchains without compromising security or confidentiality. Keep is the network behind tBTC, the first secure and decentralized tokenized bitcoin on Ethereum.

Loom Network provides developers the scalability and usability they need to build high-performance user-facing DApps today. With seamless integrations to Bitcoin, Ethereum, Binance Chain, and all major blockchains, deploying once to Loom lets you future-proof your DApps by reaching the largest number of users possible. Loom Network is a multichain interop platform live in production since early 2018. Optimized for scaling high-performance DApps that require a fast and smooth user experience, the network allows DApps to offer a UX comparable to traditional applications and onboard new users without the friction of needing to download crypto wallet software. This allows developers to integrate assets from all major chains, as well as build a DApp only once and offer it to users on all platforms simultaneously. The token is also used by developers to pay for DApp hosting on Loom Network. Unlike Ethereum, developers pay a flat monthly fee to host their DApps on Loom.

Hermez is an open-source ZK-Rollup optimized for secure, low-cost and usable token transfers on the wings of Ethereum. Hermez seamlessly integrates into the fabric of the Ethereum ecosystem and enables low-cost token transfers for an inclusive economy. Cost-efficient token transfers and swaps with high throughput. Decentralized and open-source architecture. Computational integrity for secure transactions. By using zero-knowledge technology, transfer costs are significantly reduced, allowing more accessible financial services for mainstream adoption. Computational integrity and on-chain data availability are guaranteed by zero-knowledge-proof technology while preserving the public blockchain properties of Ethereum. Hermez's mission is to create an inclusive, resilient and highly efficient payment network for the next generation of digital currencies to ensure everyone has the freedom to transact.

Astar Network is a scalable and interoperable infrastructure for Web3.0. Since Astar Network is built with Parity’s Substrate framework, it can be a future Polkadot parachain that also acts as a scalable smart contract platform. The Polkadot Relaychain, by design, does not support smart contracts. This allows Astar the opportunity to fill in this gap. Scalability is obviously one of the most crucial demands dApp developers have. Ideally, the developers can build whatever applications on Astar Network without having to consider its scalability. Astar Network is an open-source project. There are a lot of opportunities to get involved in our ecosystem. Astar Network is an open-source project anyone can join, develop, and modify. Astar Network's mission is to provide a scalable, interoperable, and decentralized application platform that defines and realizes the new form of the web, Web3.0.

Write Ethereum-compatible smart contracts in popular programming languages, & run them much faster, on Substrate. A decentralized open source business model funded by developer treasuries on participating blockchains. All existing Ethereum smart contracts work on ParaState’s Ewasm VM (Pallet SSVM) without any change. ParaState expands the developer ecosystem by supporting 20+ programming languages to create Ethereum-compatible smart contracts. Examples include generic programming languages such as Solidity, Fe, Rust, and JavaScript, and domain-specific languages (DSLs) such as MOVE, DeepSEA, and Marlowe. Substrate-based blockchains, such as Polkadot parachains, already enjoy much higher TPS (transactions per second) than Ethereum. For a smart contract platform, compute performance is more important than TPS throughput. Try deploying smart contracts on ParaState.

Blockchain-empowered smart contracts are isolated from the internet world and cannot access external data directly. Computation within the smart contract is also excessively expensive and limited by resource capacity. A Decentralized Oracle service supporting multiple heterogeneous blockchains. DOS Network brings real-world data, event and computation power to smart contracts in a secure, reliable, efficient and scalable way. With DOS Network, many scenarios like flight delay insurance are able to achieve automatic indemnification by bringing external insured events to the on-chain insurance contract. Stablecoins and crypto derivatives require frequent usage of DOS Network to fetch real-time price feeds reliably and verifiably. DOS Network makes it easy for crypto lending platforms to get token exchange rates, import borrowers' social media data and trustlessly determine the interest rates on the fly.

DAppChain is TRON's sidechain project. The goal is to help DApps to operate on TRON with lower energy consumption, faster speed and enhanced safety, providing unlimited capacity for TRON's main network. The sidechain uses the DPoS consensus, the same as the mainchain. It supports smart contracts and almost all of the functionalities of the mainchain. TRON users can easily adapt to the sidechain, and developers can quickly migrate or develop new DApps on the sidechain. DAppChain is committed to provide all ecosystem participants with a highly flexible, well-configured, and highly customized network of multiple sidechains. This is also one of the characteristics of each sidechain in DAppChain that is different from the main chain. The resource consumption on the sidechain can be much lower. For the same transaction, the cost of resources consumed is only a fraction of the cost on the mainchain.
