`@metamask/get-entropy-example-snap`

This snap demonstrates how to use snap_getEntropy JSON-RPC method to get entropy from the MetaMask extension, and use it to sign a message.

Snap manifest

Note: Using snap_getEntropy requires the snap_getEntropy permissions. Refer to the documentation for more information.

Along with other permissions, the manifest of this snap includes the snap_getEntropy permission:

{
  "initialPermissions": {
    "snap_getEntropy": {}
  }
}

This permission does not require any additional configuration.

This snap exposes an onRpcRequest handler, which supports the following JSON-RPC methods:

signMessage: Derives a private key using the snap_getEntropy method, and uses it to sign a message. For this particular example, we use the BLS12-381 elliptic curve to sign the message.

For more information, you can refer to the end-to-end tests.
