Smart Donations is a blockchain-based platform that enables users to program and set conditions on charitable donations. Users set up contracts to donate in response to real-world events, e.g., whenever an earthquake is detected or an activist tweets about refugees. We designed Smart donations with Oxfam Australia, trialled it over 8-weeks with 86 people and qualitatively analysed questionnaires and interviews about their experiences. Temporal qualities emerge when automation enforces conditions that determine when donations are made. These contributed to participants' sense of immediacy in donating to humanitarian crises, ongoing involvement while awaiting conditions to be met, and awareness of events that are usually unconscious. We suggest that automation can reveal diverse temporal registers, in real-world phenomena, sociality, morality and everyday life, which contribute to experiencing a 'right time' to donate. Thus, we recommend adopting a sensitivity to right time in designing for multiple temporalities in FinTech more generally.
