# Security High Yield Vaults are built with security as a core principle. They use audited, battle-tested components and a modular design that minimizes custom logic and reduces attack surface. *** ### **Security Design** High Yield Vaults follow a modular architecture where each operation is isolated and clearly defined. Key principles include: * Protocol-Native Integrations\ Looping strategies rely on audited lending protocols, flash loans, and decentralized exchange infrastructure rather than custom execution logic. * ERC-4626 Vault Standard\ High Yield Vaults follow the ERC-4626 tokenized vault standard, ensuring predictable accounting and transparent share-to-asset conversions. * Modular Architecture\ Borrowing, looping, and unwinding are implemented as independent modules, reducing complexity and limiting blast radius in the event of an issue. * Minimal Custom Logic\ Superlend adds only the automation and configuration required to manage leverage. Core operations rely on well-tested external protocols. *** ### **Risk Controls** The vault enforces risk parameters at the smart contract level, including: * Loan-to-value (LTV) limits * Liquidation thresholds * Maximum leverage caps These controls are designed to help prevent unsafe positions, but they do not eliminate risk. *** ### **User Safety Guarantees** * Permissionless Withdrawals\ Users can withdraw or unwind positions at any time. The vault handles deleveraging automatically when required. * Non-Custodial Design\ Funds remain in non-custodial smart contracts at all times. Superlend never takes direct custody of user assets. *** ### **Audits & Reviews** All core High Yield Vaults contracts and strategy logic have been audited by [Sherlock](https://sherlock.xyz/) prior to deployment. In addition: * Internal security reviews are conducted before releases * Protocol dependencies are reviewed before integration * Modules are monitored continuously after launch {% file src="" %} {% file src="" %} ### **Important Reminder** While security best practices and audits reduce risk, leveraged strategies remain inherently complex. Users should understand the mechanics and risks before depositing. For more detail on how leverage works, see **How It Works**.
