Patrick McCorry: Review Signer APIs After Binance Hack

Patrick McCorry referenced the paper “Programming Satan’s Computer” to stress lessons from the Binance hack, noting that private keys can stay safe yet signers must never function as oracles. The software must block the signer from signing arbitrary messages sent to it, and the protocol must specify exactly what gets signed along with verification checks so any byte difference triggers an error. McCorry advised teams to audit their APIs and confirm what messages their signers will accept.
