Multi-Sig Approval Exposure: Hidden Risks in Shared Wallets

Published: Jan 25, 2026

Shared wallets reduce single-point failure, but misconfigured roles and approvals can create silent transfer risks.

Multi-signature wallets are safer, yet approval chains can still be abused.

Unclear operator roles and outdated approvals often cause preventable losses.

Key Highlights
  • -Review signer roles quarterly
  • -Limit delegate approvals
  • -Track cross-wallet approval chains

Where exposure happens

Delegated signers or old dApps may keep permissions longer than intended.

Attackers target the weakest signer rather than the whole group.

Hardening multi-sig setups

Enforce signer rotation and revoke unused delegate permissions.

Document approval policies and alert on abnormal signer activity.
