The HST Frontier Fields (HFF) program presents an extraordinary opportunity for the detection of lensed, high-redshift transients (primarily supernovae, SNe) out to z~3. Over the last 2 years we have been searching the HFF data and following up lensed transients and their host galaxies with HST imaging and ground-based spectroscopy. We have discovered ~40 SNe, which will contribute to tests of Type Ia SN progenitor models by improving rate measurements reaching to ∼2.5. Our sample also includes a subset of highly magnified objects like the multiply imaged SN Refsdal. Positions and time delays of such multiply imaged transients provide powerful constraints for the dark matter distribution in galaxy clusters. In addition, our collection of lensed Type Ia SNe are providing a rigorous test of cluster mass models by directly measuring the lensing magnification. Finally, the rapid and deep imaging of the HFF program has surprisingly opened up a new discovery space, revealing at least one peculiarly fast and faint astrophysical transient. We propose to extend this program into the third and final year of the Frontier Fields survey, finishing the collection of this unique and diverse sample of distant transients.
