# Security Audit

<figure><img src="/files/g1ruhuSI7C8L77gIjCUt" alt="" width="375"><figcaption></figcaption></figure>

Security and trust are foundational to the LeMONAD ecosystem. To ensure the robustness, reliability, and safety of user funds, **all LeMONAD smart contracts have undergone a comprehensive security audit conducted by Stonewall Security**, a specialized Web3 security firm focused on high-assurance smart contract protection.

#### Auditor: Stonewall Security

**Stonewall Security** is a Web3-native auditing firm specializing in smart contract audits designed to provide what they describe as *“immovable Web3 security.”* Their work focuses on identifying vulnerabilities, validating protocol logic, and hardening DeFi systems against real-world attack vectors.\

* LEMON Token
* Vault Contract
* Team Vesting Contract

**DEX Contracts**

#### Audit Scope and Methodology

The Stonewall audit assessed both technical vulnerabilities and protocol-level logic across all contracts. Key focus areas included:

| Category         | Description                                                     |
| ---------------- | --------------------------------------------------------------- |
| Reentrancy       | Protection against callback and state manipulation attacks      |
| Access Control   | Verification of role-based permissions and privilege boundaries |
| Integer Safety   | Prevention of overflow and underflow vulnerabilities            |
| Oracle Security  | Secure integration with Pyth price feeds and entropy sources    |
| Front-Running    | Mitigation of MEV and transaction-ordering risks                |
| Logic Validation | Review of economic and business logic correctness               |
| Gas Efficiency   | Identification of unnecessary gas usage and optimizations       |

#### Ongoing Security Commitment

While audits significantly reduce risk, LeMONAD recognizes that security is an ongoing process. The protocol follows best practices including conservative permissions, transparent on-chain logic, and upgrade pathways where appropriate. Future upgrades and feature expansions may undergo additional reviews to maintain the highest security standards as the ecosystem evolves.
