@polkadot/api - npm Package Versions

16.0.1 May 19, 2025

Breaking Changes:

• With the upgrade to Metadata v16, several fields have been removed or replaced. The following fields no longer exist in the updated metadata definitions:
  • type: This field has been completely removed in Metadata.
  • version: Previously part of ExtrinsicMetadata. Replaced by versions, which now holds an array Vec<u8> of supported extrinsic versions instead of a single value.
  • extraType: This field has been completely removed in ExtrinsicMetadata.
  • signedExtensions: Previously part of ExtrinsicMetadata. Replaced by transactionExtensions, which provides a more structured definition of extensions, and transactionExtensionsByVersion, mapping versions to active extensions.
