findOwnInput :: ScriptContext -> Maybe TxInInfo Source #
Find the input currently being validated.
findDatum :: DatumHash -> TxInfo -> Maybe Datum Source #
Find the data corresponding to a data hash, if there is one
findDatumHash :: Datum -> TxInfo -> Maybe DatumHash Source #
Find the hash of a datum, if it is part of the pending transaction's hashes
findContinuingOutputs :: ScriptContext -> [ Integer ] Source #
Finds all the outputs that pay to the same script address that we are currently spending from, if any.

CurrencySymbol
to a
ValidatorHash
