Turning Words into Killer Apps Defi Actions
summary
Flow introduces Actions standard as reusable onchain functions that abstract protocol specifics, claiming composable swaps, supply/borrow/stake workflows and a shared metadata model; Cadence features (resource-oriented args, pre/postconditions) enable atomic batched transactions and onchain agents with scheduled callbacks that run in the emulator and can loop until funds deplete. Demoed live swap and recurring callbacks executing successfully; 80% of 2025 transactions are automated, NBA Top Shot peaked with more daily tx than total Ethereum, and hackathon prizes include a $10k pool and $6k top-app award.
