This design ensures that: * The Agent can rebalance and manage positions efficiently. * The **multisig always remains the ultimate owner and authority**. * No centralized operator, including Zyfai, can unilaterally move funds. ### MPC Wallet Compatibility Many institutional teams rely on **MPC (Multi‑Party Computation) wallets** as their primary custody layer.\ Zyfai is built to integrate with these flows rather than replace them. * **We are compatible with leading MPC solutions** such as [**ForDefi**](https://fordefi.com), enabling institutions to: * Keep existing custody and policy engines. * Use MPC to create and sign transactions that configure and control Zyfai Smart Accounts. * **Session keys for execution, MPC for governance:**\ MPC handles high‑level governance and approvals, while Zyfai’s session keys handle **day‑to‑day on‑chain execution** within strict, predefined limits. This unlocks one of the most widely used institutional security setups while allowing Zyfai to generate **predictable, risk‑managed yield** on top. ### Safe Integration and Custom App Wrapper We have developed a **Safe wrapper** that allows any institution to: * Add Zyfai as a **custom Safe app**. * Monitor and manage positions directly from the **Safe UI**. * Keep portfolio management inside the governance environment teams already know. This minimizes operational friction and avoids the need to adopt yet another standalone interface for treasury operations. ### Security and Verifiability As detailed in the [High-Level Technical Implementation page](/docs/product/overview/high-level), Zyfai combines: * **[Audited Smart Account infrastructure](/docs/product/overview/audits)** based on [Safe7579](/docs/product/infra/safe7579). * **[The Security Proxy Gateway](/docs/product/control/proxy)** using: * An executor module that validates DeFi calldata before execution. * A target registry that whitelists allowed contracts and selectors. * **Non‑custodial design:** No global vault; each user has its own Smart Account. All core contracts are **open sourced** and **[audited by Sherlock](/docs/product/overview/audits)**, and our work on **verifiable, rule‑based rebalancing** brings an additional layer of transparency for compliance and risk teams.
