# UnknownParametersException

`class UnknownParametersException : TransactionResolutionException`

Thrown if a transaction specifies a set of parameters that aren't stored locally yet verification is requested. This should never normally happen because before verification comes resolution, and if a peer can't provide a new set of parameters, TransactionResolutionException will have already been thrown beforehand.
