Why can multisig wallets also suffer from management failures?

Multisig wallets reduce the risks of a single private key being compromised by requiring multiple signers to jointly approve transactions.

But multisig does not mean absolute security.

The following five situations can still create risks:

01｜Keys stored together: Multiple signers’ keys may all be affected if the same device or account is compromised.

02｜Lack of independent review: If everyone relies on other members to check transactions, multisig can become a mere formality.

03｜Unreasonable signing threshold: A threshold that is too low weakens protection, while one that is too high may hinder normal operations and emergency recovery.

04｜Problematic transaction details: Multisig cannot automatically detect malicious contracts, incorrect addresses, or dangerous operations.

05｜Missing management procedures: Signers leaving, lost keys, or outdated permissions can all create risks.

Effective multisig management requires setting a reasonable signing threshold, storing keys independently, reviewing transactions independently, and establishing clear emergency procedures.

Multisig is not simply about distributing trust among more people, but about establishing a reliable system of permissions and review.

Next: Why does a contract passing an audit still not guarantee absolute security?
