Following input from core teams and ecosystem contributors, a decision has been made to prioritize attracting existing third-party providers to Polkadot Hub to facilitate the porting of top Ethereum dapps and enhance functionality for Polkadot rollups. As PVM does not offer full compatibility with many of these providers, the Parity team is strategically prioritizing delivery of a 100% EVM compatible solution with support for legacy Solidity versions by mid-December. For this, they have chosen REVM, a fast, well-maintained, and frequently audited Ethereum implementation trusted by major projects like Foundry, Hardhat, and Optimism.
