the Safe team responded to the Radiant Capital security incident, stating that hackers destroyed the signature process through external devices and induced the signing of malicious transactions. Safe emphasizes the risks of blind signatures, especially when using hardware wallets. To improve security, Safe recommends using multi-device signatures (such as a combination of Ledger and Trezor) and connecting devices through trusted interfaces. In addition, Safe is researching conditional signature technology and considering directly calculating the Ledger hash in the interface to facilitate user verification. Safe promises to work with hardware wallet suppliers and the community to improve the transaction signature process.
