# Operational Security

**Multi-Party control**

Every code upgrade and treasury transaction must be approved by a 3/3 multisig. This is enforced through a multisignature contract which only allows code upgrades when all signers have signed the upgrade with a cold storage wallet.

**2FA**

All accounts of the protocol, administrators, and moderators are secured by two factor authentication using an authenticator app, reducing the likelihood of access being granted to a malicious actor via methods such as sim-swapping.

**Audits**

Our auditors have checked for centralization risks when auditing . This means that potential backdoors, deliberate exploit opportunities and other risks are reported by the auditor with or without the contributor's approval.
