# Safety Module

The primary mechanism for securing the SiO2 Finance Protocol is the incentivization of SIO2 holders to lock tokens into a Smart Contract-based component called the Safety Module (**SM**). The locked SIO2 tokens will be used as a mitigation tool in case of a Shortfall Event within the money markets that belong to the SiO2 Finance ecosystem. A Shortfall Event occurs when there is a deficit. The interpretation for the occurrence of a Shortfall Event is subject to the Protocol Governance vote, detailed in [Governance](https://sio2-finance.gitbook.io/en/tokenomics/governance).
