Utilities related to browser extensions

This package contains a library for both building a browser extension and interacting with it from web content.

Developers, see this getting started guide.

Philosophy

A browser extension is a convenient place to implement a wallet so that it can be used with dApps. Prefer to have more responsibilities in the dApp, such as connecting to a node, estimating or configuring gas, setting nonces, and submitting transactions.

An extension that works by altering the JavaScript environment for all sites is a lot to trust. Prefer to have a dApp request to interact with an extension.

Inventory of what's here
