Summary: Conducted a thorough security audit for Vultisig, a multi-chain, multi-platform threshold signature vault and wallet. Vultisig enhances security through multi-factor authentication without requiring specialized hardware. The platform improves user onboarding and wallet management by eliminating the need to secure a seed phrase and enhancing on-chain privacy through multi-party computation (MPC) with the Threshold Signature Scheme (TSS).

Objective: - Identify vulnerabilities that could compromise user funds and platform security. - Ensure secure and efficient handling of staking and delegation processes. - Optimize gas usage to improve transaction efficiency and reduce costs.

Outcome: - Discovered and reported several high and medium-risk vulnerabilities. - Provided actionable recommendations to improve protocol security. - Enhanced contract efficiency, leading to reduced gas fees.
