npm @polkadot/api 1.34.1

Upgrade priority: High. Metadata v12 is the next major version containing structural data exchange changes and will start rolling out to test and live networks in due course.

  • Breaking change The Decorated (from @polkadot/metadata) class signature has changed. It now always expects a valid Metadata object to be passed-in, instead of raw data. It is recommended to create a Metadata object, set it on the registry with .setMetadata and then only create a Decorated instance. (Only affects metadata-only users of the API)



  • Ensure Metadata retrieval does not pollute the default registry
  • When passing { nonce: -1 } to signAndSend the API will use system.accountNextIndex to determine the nonce
  • Ensure that upgrades override old registry types (non-specified in current)
  • Support for Metadata v12 with fixed indices
  • Cleanups for WebSocket class detection and creation
  • Ensure that ignored map params yield an error on iterKey
  • Cater for older chains in derive democracy locks (availability detection)
