Ethereum Provider API

Brave injects a windows.ethereum provider object on all pages.
This object is defined by EIP-1193.

This object gives websites the ability to:

• Make requests to an Ethereum node (or a compatible network) to read data from the blockchain
• Request permission to 1 or more Ethereum accounts
• Ask the user (if given permission previously) to sign / submit a transaction
• Ask the user (if given permission previously) to sign a message
