# MAS System

## Multi-Approval Security System

The Promethium engineering team has meticulously crafted a security system that operates as a distributed network. This network involves multiple proposers and approvers for every action, be it executing transactions on smart contracts or facilitating interactions between the backend and the smart contracts.

There are two distinct types of services within this system. The first type proposes rebalancing, while the second type approves it. Notably, there can be multiple instances of the latter service, each operating independently.

These services are managed from different wallets, ensuring a high degree of isolation. This structure is instrumental in enhancing security, as it provides a robust defense mechanism. Even in the event of a breach, this design helps prevent unauthorized rebalancing.
