SlowMist Cosine: Smart contract owners should use multi-signature and hardware wallets to strengthen key management
Jinse Finance reported that SlowMist's Cosine posted on X, stating, "The Owner of the project's smart contract must use multi-signature, and the person holding the key must only use a hardware wallet that supports complex signature parsing and has a large screen... From mnemonic generation to usage, everything should be done within the hardware wallet. Add a Passphrase or use SSS (Shamir's Secret Sharing) for backup, which makes backing up more secure... Also, stay calm during daily use, avoid signing blindly, and conduct disaster recovery drills. Unexpected situations will definitely occur during drills if you're not careful."
