In decentralized finance (DeFi), users often sign transactions without visibility into real-time on-chain risks. AMM pools and DeFi vaults can be manipulated through flash-loan attacks, temporary liquidity distortions, malicious tokens, unsafe swap paths, or vault share price manipulation, exposing users to unexpected losses even when the interface appears normal. PreFlight introduces a real-time pre-transaction security layer that intercepts DeFi transactions before they are signed and analyzes their calldata. It performs automated security checks, simulations, and real-time state verification for swaps and vault interactions. By detecting unsafe routing, malicious tokens, manipulated liquidity states, and risky vault operations, PreFlight warns users before execution and routes verified transactions through a secure execution layer, enabling safer interactions with DeFi protocols.
