Wirex’s choice to employ the Polygon CDK, an openly accessible codebase designed for launching Ethereum Layer 2 (L2) chains powered by Zero-Knowledge (ZK) technology, allows it to establish its own payments-focused L2 solution. Importantly, all chains created using the Polygon CDK maintain interoperability, ensuring automatic access to the collective liquidity of all Polygon chains and one-click accessibility to Ethereum’s comprehensive liquidity pool. Additionally, they provide heightened security through the utilisation of ZK proofs, along with near-instant finality.
