## Multi-Signature Vaults

Multi-Signature Vaults are smart contract-based custody solutions that require multiple independent keys to authorize a transaction. Instead of a single private key, which represents a single point of failure, these vaults mandate that a predefined number of signers must agree before funds can move.

This is a primary security feature for institutional crypto custody and decentralized autonomous organizations. In the context of derivatives, they protect the collateral pool from unauthorized withdrawals by internal actors or external hackers.

The threshold for signatures can be adjusted based on the risk profile of the assets. This adds a layer of redundancy and institutional-grade security to the protocol.

It is the digital equivalent of a bank vault that requires multiple keys held by different individuals to open.
