Best Smart Contract Apps 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.

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.
