# Wallet and Transaction Security

#### MPC Key Management & Policy Engines

All collateral assets and smart contracts are protected by industry-leading Multi-Party Computation (MPC) key management solutions provided by Fordefi and Fireblocks.

* **Cryptographic Guardrails:** All on-chain transactions initiated by the asset manager are restricted by MPC-based policy engines. These engines ensure that trades and transfers can only occur with explicitly whitelisted counterparties.
* **Active Threat Prevention:** We deploy Blockaid as an advanced co-signer solution directly within our MPC workspaces. This provides continuous on-chain transaction simulation and monitoring, adding a critical layer of protection against malicious smart contracts and on-chain threats.
* **Strict Governance:** Any changes to these policy engines or counterparty whitelists require a strict dual-control review process by trained Midas approvers based on a required quorum.
* **Tamper-Proof Logging:** Every transaction, policy update, whitelist modification, and user configuration is permanently recorded in a tamper-proof audit trail.

#### Backup Security

All collateral assets and smart contracts are secured using institutional-grade MPC key management solutions. Backup procedures are designed to ensure strong redundancy, strict access controls, and continuous monitoring, aligned with industry best practices.
