# MetaMask Snap Setup

COTI MetaMask Snap is a plugin that enables you to execute encrypted transactions on the COTI Blockchain Network by granting Snap secure access to your [AES Keys](https://docs.coti.io/coti-documentation/how-coti-works/advanced-topics/aes-keys).<br>

* When you click the **Unlock** button on the Private Tokens dashboard for the first time, a prompt titled “**MetaMask Snap Required**” appears. Click **Get COTI Snap** and follow the install flow. Use [dev.metamask.coti.io](https://dev.metamask.coti.io/) on **COTI Testnet** or [metamask.coti.io](https://metamask.coti.io/) on **COTI Mainnet** (the portal opens the matching link when you connect).
* Once the installation of COTI Snap is complete, click on the “Enable Snap” button.
