Aptos Labs has unveiled Event-Driven Transactions (AIP-125), a major upgrade that brings on-chain automation closer to the standards of traditional finance. In today’s markets, more than half of all listed derivatives are traded algorithmically, and CFTC data confirms that algorithms dominate FX and U.S. equity volumes. According to Aptos Labs, DeFi can only reach true parity with TradFi once native, first-class automation replaces the fragmentation and inefficiencies of off-chain bots and keepers.
With Event-Driven Transactions, developers can now schedule, trigger, and compose actions natively on-chain. This enables:
Time-based automation: recurring buys, hourly funding rollovers, or scheduled token unlocks.
Price-based actions: stop-loss or take-profit orders that trigger automatically at set market thresholds.
Workflow-based automation: chaining multiple steps—such as selling token A, buying token B, and depositing into protocol C—in a single automated sequence.
Aptos positions this as a building block toward a global on-chain trading engine characterized by sub-second latencies, deterministic fees, and real-time execution of advanced financial logic.
Event-Driven Transactions complement ongoing innovations across the Aptos stack, including Raptr (next-gen consensus), Zaptos (pipeline concurrency), and the network’s composable on-chain order book—opening a new design space for high-performance DeFi.
