Safari Wallet

This is an experiment to see whether we can build a viable browser extension Ethereum wallet for Safari on macOS and especially iOS.

Overview

A diagram might be useful, but basically the current plan/rundown is:

• The window.ethereum object (EIP-1193 JavaScript API) will be injected into each page. This way, the wallet will automatically work with all apps/dApps that support MetaMask.

• For the interface, the native Safari extension popover is used, in tandem with the WebExtensions API.

The bulk of the development is currently going on in the Shared (App and Extension) and Shared (App) folders.

It is important to read these files:

• Shared (App) > Shared (Extension) > Resources > README.md

• Shared (App) > Shared (Extension) > Resources > ethereum > README.md

• test-dapp > README.md

Popover

Setting up the popover

1. Open this repo as a project in Xcode

2. From the menu bar: File > Packages > Update to Latest Package Versions

3. In the leftmost top bar breadcrumb, which should be on "macOS" by default, switch it to "iOS"

4. Set the following breadcrumb to a mobile device, perhaps "iPhone 13 Pro"?

5. Click the play button to start the emulator

6. Once the emulator has loaded (it might take a few minutes), open the Settings app

7. Settings > Safari > Extensions > Wallet Extension

8. Switch to on

Then, to test the popover, navigate to https://safari-wallet-test-dapp.vercel.app in Safari (or http://localhost:3000/, if you're running the local dev server)

You can also set up the local dev server here (WIP): https://github.com/natclark/safari-wallet-test-dapp

Keys

Use your own Alchemy or Infura keys by creating a file called keys.swift in the Shared (App and Extension) directory. The filename is added to .gitignore so won't be committed.

// Shared (App and Extension)/keys.swift
struct ApiKeys {
    static let alchemyMainnet = "<YOUR KEY HERE>"
    static let alchemyRopsten = "<YOUR KEY HERE>"
    static let infuraRopsten = "<YOUR KEY HERE>"
    static let infuraMainnet = "<YOUR KEY HERE>"
    static let covalent = "<YOUR KEY HERE>"
    static let unmarshal = "<YOUR KEY HERE>"
    static let etherscan = "<YOUR KEY HERE>"
    static let zerion = "Demo.ukEVQp6L5vfgxcz4sBke7XvS873GMYHy"
}
