High-level summary​

DApp Connector API v4.0.1 is a patch release on the v4.0.0 redesign. It closes a gap in the transaction method types: the option to disable fee payment was only available on makeIntent, and this release adds the same payFees option to all transacting methods in a backwards-compatible way. All transacting methods now share a uniform API.

Disabling fee payment lets a DApp construct a transaction whose fees are paid elsewhere, for example by a sponsor wallet running in a separate, dedicated service.

Audience​

This release note is relevant for developers who:

  • Use @midnight-ntwrk/dapp-connector-api in their DApps.
  • Build sponsored-fee flows where a wallet other than the connected one pays transaction fees.
  • Maintain wallet implementations compatible with the DApp Connector API.

What changed (Summary of updates)​

  • Added the payFees option to all transacting methods. Previously only makeIntent exposed it.
  • Documented the motivation for the option in the API specification.

New features​

payFees option on all transacting methods​

Every transacting method now accepts the payFees option that makeIntent already had, so you can disable fee payment on any transaction the connector builds. The change is backwards-compatible: omitting the option keeps the existing behavior of paying fees from the connected wallet.

Breaking changes​

No breaking changes in this release.

Known issues​
