@metamask/ethereum-provider-example-snap

This snap demonstrates the use of the endowment:ethereum-provider permission and the corresponding ethereum global. This is similar to the window.ethereum API, but it does not have access to all methods.

Snap manifest

Note: Using ethereum requires the endowment:ethereum-provider permissions. Refer to the documentation for more information.

Along with other permissions, the manifest of this snap includes the endowment:ethereum-provider permission:

{
  "initialPermissions": {
    "endowment:ethereum-provider": {}
  }
}

This permission does not require any additional configuration.

Snap usage

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

• getGasPrice: Get the current recommended gas price from an Ethereum provider.
• getVersion: Get the Ethereum network version from an Ethereum provider.
• getAccounts: Get the Ethereum accounts made available to the snap from an Ethereum provider.

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