Polygon zkEVM
Polygon's bytecode-level zkEVM (separate from Polygon PoS) — uses validity proofs to settle to Ethereum.
Polygon zkEVM is a Type 2 zkEVM. The Polygon ecosystem additionally includes Polygon PoS (the original sidechain) and the Polygon CDK (a kit for deploying app-specific zk-chains that share an aggregated bridge).
