 Events are emitted using [EventEmitter](https://nodejs.org/api/events.html).
 
 #### notification
 
-All subscriptions from the node emit on "subscription type" (e.g. `eth_subscription`, or `ssh_subscription`). Attach listeners with:

-To create a subscription, call `ethereum.send('eth_subscribe')` or `ethereum.send('shh_subscribe')`. The subscription object will emit through the specific subscription type.

-#### eth_requestAccounts
-
-The provider supplied to a new dapp **MUST** be a "read-only" provider: authenticating no accounts by default, returning a blank array for `eth_accounts`, and rejecting any methods that require an account with Error code `4100`.
-
-If the dapp has been previously authenticated and remembered by the user, then the provider supplied on load **MAY** automatically be enabled with the previously authenticated accounts.
-
-If no accounts are authenticated, the `eth_requestAccounts` method **MUST** ask the user which account(s) they would like to authenticate to the dapp. If the request has been previously granted and remembered, the `eth_requestAccounts` method **MAY** immediately return.
-
-The `eth_requestAccounts` method **MUST** resolve with an array of the account(s) addresses or reject with an `Error`. If the account(s) enabled by the provider change, the `accountsChanged` event **MUST** also emit.

-For full specification of the `eth_requestAccounts` RPC method, see [EIP 1102: Opt-in account exposure](https://eips.ethereum.org/EIPS/eip-1102).

 ### Events
 
 The provider **SHOULD** extend from `EventEmitter` to provide dapps flexibility in listening to events. In place of full `EventEmitter` functionality, the provider **MAY** provide as many methods as it can reasonably provide, but **MUST** provide at least `on`, `emit`, and `removeListener`.
