Polygon zkEVM has support for all EVM opcodes, provides identical gas pricing to the EVM, and has plans to add support for all precompiled EVM smart contracts. This means most Ethereum smart contracts, wallets, and dev tools will work seamlessly on Polygon zkEVM. Polygon zkEVM utilises cryptographic zero-knowledge technology to provide validation and fast finality of off-chain transaction computations with frequent validity proofs. It aims to deliver throughput similar to Polygon PoS.
