+## 🔒 Security & Audits
+
+The **Stargate Bridge** uses the **LayerZero protocol** under the hood, which
+provides secure cross-chain communication infrastructure. LayerZero is a
+decentralized protocol that enables trustless cross-chain messaging without
+requiring intermediate chains or wrapped tokens.
