Purser

Purser simplifies interaction with Ethereum based wallets. It supports both hardware and software wallets and provides a consistent and predictable interface to work with during dApp development.

Purser is:

Simple - Has an easy and intuitive API. Get started in minutes!

Predictable - Uses the same commands for all wallet types.

Sane - Maintains developer health by using proper error messages, validations and sanitisers.

Plug & Play - Supports Hardware (Ledger, Trezor) and Software (ethers.js) wallets out of the box.

Purser was brought to you by the fine folks at Colony. To learn more about Colony, you can visit the website or read the white paper.

Quickstart (software wallet)

To use the software wallet (based on the ethers wallet):

Installation

npm install @purser/software

Usage

Create a new wallet

import { create } from '@purser/software'

const wallet = await create();

console.log(wallet); // { address: '...', privateKey: '...', publicKey: '...' }

or open an existing one (based on the mnemnonic)

import { open } from '@purser/software'

const wallet = await open({ mnemonic: '...' });

console.log(wallet); // { address: '...', privateKey: '...', publicKey: '...' }

Documentation

Please see the documentation with detailed examples and explanations.

Packages

Purser is a monorepo consisting of a collection of Ethereum wallet libraries:

To build and release

In the root directory:

npm i
npm run bootstrap
npm run build
npm run publish

To clean detritus and reset the repository:

./node_modules/.bin/lerna clean
npm run bootstrap

The future

We plan to add support more hardware wallets and other features that will make wallet interactions even easier. Stay tuned!
