All transactions in your Zengo wallet can only be initialized by you, and Zengo can never spend your funds or access the assets in your wallet. Zengo’s MPC security system requires that any transaction you make be validated by Zengo’s servers before being broadcasted to the blockchain. This adds an additional layer of security for all Zengo users, and helps guarantee the integrity of your transactions, including hacks, fraud detection, and other types of risks. For example: Your built-in Web3 firewall – ClearSign – does not block transactions with blockchain apps that are marked as risky but only informs you clearly about the risks associated. You can always bypass this safety notification: Ultimately you are responsible for your assets and how you want to use them. While in theory this secure architecture could be used to prevent certain transactions from being broadcasted, Zengo has never done so – ever since the company was founded.
