Annotations

Annotation is a form of metadata that is added to a function of a dApp script.

At the present moment, there are two annotations: @Callable(i) and @Verifier(tx). The variable name in the annotation is required even if the function does not use it.

An annotated function cannot be called inside a dApp script.

@Callable(i)

Annotation of a callable function.

Variable i contains an Invocation structure representing certian fields of the invocation.

@Verifier(tx)

Annotation of a verifier function.

Variable tx contains a structure of transaction or order sent from a dApp's account.
