+If passed, this VIP will transfer the ownership of the following contracts, from the Guardian wallet to the [Normal Timelock](https://basescan.org/address/0x21c12f2946a1a66cBFf7eb997022a37167eCf517):

+From now on, every privilege function executable only the owner/admin of the contract should be executed with a Normal VIP. To transfer the ownership of this contract, [this](https://app.safe.global/transactions/tx?safe=base:0x1803Cf1D3495b43cC628aa1d8638A981F8CD341C&id=multisig_0x1803Cf1D3495b43cC628aa1d8638A981F8CD341C_0x27fce7f893b9ee2f09171e507f69cad2ee78580c0801d0851b66f2e4966bad7d) transaction is required, where the two steps transfer is initiated by the Guardian wallet. If this VIP passes, that transaction will be executed. Otherwise, it will be rejected.
+
+Moreover, this VIP sets the trustworthiness relationships among the XVS bridge contracts of the supported networks and Base, wrongly set in the [VIP-407](https://app.venus.io/#/governance/proposal/407?chainId=56).
+
+#### Security and additional considerations
+
+We applied the following security procedures for this upgrade:
+
+- **VIP execution simulation**: in a simulation environment, validating the ownership is properly transferred and the Normal Timelock can execute the privilege functions
+- **Deployment on testnet**: the same transfer has been performed on testnet
