zkSync
Also known as: zkSync Era, zkSync 2.0
A Layer‑2 scaling solution for Ethereum based on ZK‑rollups.
zkSync is a Layer‑2 scaling protocol built on Ethereum that leverages zero‑knowledge rollups (ZK‑rollups) to bundle hundreds of transactions into a single proof, reducing gas fees and increasing throughput. Users enjoy near‑instant confirmations, low transaction costs, and strong security guaranteed by Ethereum's base chain. zkSync supports EVM‑compatible smart contracts, token transfers, and DeFi features, while maintaining decentralization and ensuring on‑chain settlement.
