## Multisig Security Models

Multisig security models refer to cryptographic schemes that require more than one private key to authorize a transaction or modify smart contract state. By distributing authority across multiple entities or devices, these models eliminate single points of failure inherent in traditional custodial wallets.

In a financial derivatives context, this mechanism is crucial for securing treasury funds or governing protocol upgrades. It utilizes an M-of-N signature requirement, where M is the minimum number of signatures needed from a larger pool of N authorized keys.

This structure enhances trust, as no single participant can unilaterally move assets or alter collateral parameters. It effectively mitigates risks associated with key theft or internal malicious activity.

Consequently, it is a foundational pillar for decentralized exchange security and institutional custody solutions.
