Polygon zkEVM
Polygon zkEVM is a type 2 ZK-EVM rollup by Polygon Labs, leveraging zero-knowledge proofs to settle Ethereum transactions at lower cost while maintaining full EVM opcode equivalence. It is part of Polygon's broader AggLayer strategy, which aims to unify liquidity across all Polygon chains. QuickSwap is the flagship DEX and has a dedicated deployment optimized for zkEVM.
