Fast radio bursts (FRBs) are energetic millisecond-duration pulses from cosmological distances whose physical origin remains unresolved. The detection of a Galactic FRB in April 2020 provided strong evidence that at least some FRBs arise from magnetars. Understanding their source population is crucial for optimizing searches and refining progenitor models. In this talk, I will discuss mechanisms that generate such coherent bursts, along with the persistent radio emission from magnetized nebulae observed for multiple localized FRBs. This late-time emission provides direct constraints on the neutron star's age and magnetic field strength. I will also describe how these sources may produce high-energy neutrinos and beta-decay-powered optical transients detectable with GWs over large distances. Finally, I will highlight the potential of cosmological FRBs as probes of He reionization, offering insights into energetic processes in the early Universe. Improved sensitivity and source localization from upcoming radio surveys, together with multi-wavelength observations, will greatly improve our understanding of these enigmatic sources over the next decade.
