No, but ERPS prefers non-cryogenic propellants, and thinks peroxide is the
best (translation:  the only sane choice) of the non-cryogenic oxidizers. 
And if you are working with peroxide, using it as a monoprop is the way to
get started. 

Availability and cost problems may eventually require reconsidering this,
but so far it is working.

Despite being a monopropellant, peroxide is noticeably the safest of the
strong oxidizers.  Cryogenic fluids can produce quite nasty gas-pressure
explosions without reacting with anything at all...
