versioning:
  scheme: protocol-version
  mechanism: >-
    ZKsync Era exposes the live protocol version via the zks_getProtocolVersion JSON-RPC
    method and the semantic protocol version through zks_getGenesis. The RPC surface itself
    tracks Ethereum JSON-RPC equivalence rather than a numbered API version in the URL.
  query_method: zks_getProtocolVersion

deprecation:
  policy_url: null
  note: >-
    No formal API deprecation-policy page found. At the SDK level the legacy zksync-web3
    JavaScript library is deprecated in favour of zksync-ethers, but this is an SDK
    lifecycle note, not an RPC endpoint sunset policy.
status_page:
  url: null
  note: >-
    No first-party ZKsync status page was verified (zksync.statuspage.io redirects to the
    statuspage.io marketing home; status.zksync.io does not resolve). Network health is
    commonly monitored via the block explorer and third-party RPC providers.
