  zkSync is a family of Ethereum Layer 2 scaling networks from Matter Labs built on
  zero-knowledge proofs. zkSync Era is the production zkEVM rollup; the ZK Stack is
  the open-source framework used to deploy ZK Chains that interoperate in the Elastic
  Network. Developers integrate via standard JSON-RPC (with zkSync-specific extensions
  for paymasters, account abstraction, and L1<->L2 messaging), the zksync-ethers /
  zksync2-* SDKs, hardhat-zksync and foundry-zksync toolchains, the canonical Bridge,
  and Blockscout-based block explorers.
