Narwallet Chrome Extension

Installation

Install Narwallets from the Chrome Web Store

Objectives

• Be the deafult chrome-extension wallet for NEAR DApps
• What Metamask does for ethereum, we intend to do for NEAR

Comparision with NEAR Official Web Wallet

• Narwallets-extension aims to be a simpler and complemetary tool to the official NEAR Web wallet
• Narwallets is designed for a desktop/laptop experience with a chromium based browser, NEAR Web wallet works on any browser and mobile
• Narwallets is available only in english, NEAR Web wallet supports multiple languages
• Narwallets is not yet integrated with Ledger or other HW Wallets
• Narwallets has only one option regading account recovery: Write-down the seed phrase. NEAR Web Wallet has other user-friendly recovery options (email & phone recovery).
• Narwallets, aiming at simplicity, has no 2FA support yet.

The good: * It's an extension-wallet: You'll be able to interact with DApps without leaving the DApp web site * Provides a similar experience as Metamask/other extension-wallets, easing the onboard of ethereum users into the NEAR ecosystem. * Each wallet can have multiple accounts. You can see the sum of all your accounts in the wallet * You can have multiple wallets by providing different user/passwords. * Accounts are first added to in safe-by-default read-only mode (no keys) * All private data is stored encrypted on chrome local storage - [x] Create free implict accounts (no near required) - [x] Lockup contract accounts are auto-discovered and treated as another account in the group - [x] Advanced mode allows you to take full control of your lockup contract account - [x] Integration with DApps. New model: wallet initiated connection to active tab, resulting in chain & wallet agnostic DApps. See Wallet integration API Documentation here

Road Map

• Trello Board at https://trello.com/b/SRbigp2g

Future versions

• Ledger integration
• 2FA Support
• Manage Create named account (currently redirecting to NEAR Web Wallet)

Dev Tooling (v0.1)

• This project uses typescript
• Being a chrome extension, no bundler/minimizer is needed
• No frameworks are used neither, this is plain typescript and a main index.html

Dev Flow (v0.1)

• Chrome Dev Tools: Map folder to Narwallets-extension/extension
• Use Chrome Dev Tools as an quick-and-dirty IDE with Edit & Continue
• Use VSCode as the main IDE - Ctrl-Shift-B to build with typescript

Low-level Technical debt

• [x] Remove plus-typescript, convert all to typescript
• [ ] npm i eslint --save-dev
• [ ] When wallet-API was added a lot of functions became async. Add npm install eslint-plugin-no-floating-promise --save-dev

We're using base crypto libs as a bundle (The ideal solution would be to have typescript versions of each lib and compile to ES2020 modules) - [ ] Replace bundle with typescript versions of basic crypto tools

We need to reduce the bundle's size. Bundle is at https://github.com/Narwallets/bundled-crypto-libs.git

Bundle includes:

• globalThis.Buffer = SafeBuffer.Buffer
• globalThis.BN = BN
• globalThis.bip39 = bip39
• globalThis.pbkdf2 = pbkdf2
• globalThis.createHmacPackage = {createHmac:createHmac}
