Transaction Extensions

PreviousSigned ExtensionsNextCommon runtime modules

Last updated 4 months ago

Means by which a transaction may be extended. This type embodies both the data and the logic that should be additionally associated with the transaction. It should be plain old data.

Transaction extensions are capable of defining logic which is executed additionally to the dispatch of the call:

  • They may define logic which must be executed prior to the dispatch of the call.

  • They may also define logic which must be executed after the dispatch of the call.
