Description
Gatekeeper decodes raw DeFi transaction calldata into structured, human-readable intents and evaluates transactions against protocol-specific whitelist rules. It supports nested, multicall, and batched operations and can be deployed in any environment or run as a sidecar in a zero-trust configuration. Originally designed for custodians and institutional wallets, it helps signing workflows validate transactions from untrusted sources against approved behavior and reduce blind-signing-style attacks.
