The NeuronNervos CKB Full-Node Desktop Wallet is a powerful tool for managing your Nervos CKB funds. This guide will walk you through the process of setting up Neuron, including the prerequisites, installation, and starting the wallet. Whether you’re a developer or just looking to use the wallet, we’ve got you covered!

Quick Start

Before diving in, ensure you have the necessary software installed. Here’s what you need:

Prerequisites

• Node.js version: 18.12.0
• Yarn version: 1.14

Install Lerna

This project utilizes lerna for package management. To install Lerna globally, run the following command:

shell$ yarn global add lerna # install lerna globally

Install Dependencies

After installing Lerna, you need to set up the dependencies. If you’re operating behind a proxy or facing slow downloads, you may want to configure your network settings accordingly:

• Set a proxy if needed.
• Set a CDN for faster downloads.

Once done, run the following commands:

shell$ yarn$ lerna run rebuild:nativemodules

Add CKB Indexer

CKB Indexer is essential to create cell and transaction indexes. Download CKB Indexer and move the binary into packages/neuron-wallet/bin/win/linux/mac.

Start Neuron

Starting from version 0.26.0, Neuron bundles a CKB binary and launches it automatically for Mainnet. If you wish to run a local CKB node, follow the guidelines in the Nervos CKB documentation to set it up prior to launching Neuron.

Note: If you run into issues starting the CKB node on Windows, ensure you have the latest Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017, and 2019.

Start Neuron in Development Mode

To start with the CKB binary for your platform, use:

shell$ .scripts/download-ckb.sh # Download CKB binary

Then run:

$ yarn start

This command will launch the UI layer (neuron-ui) and the core wallet layer (neuron-wallet). If you prefer to start them individually, use:

# start neuron-ui at http://localhost:3000
$ yarn start:ui
# start neuron-wallet
$ yarn start:wallet

Environment Configuration

To develop with the devnet, adjust the script in the packages/neuron-wallet/.env file to the dev script. For example:

TESTNET_SUDT_DEP_TXHASH=0xe12877ebd2c3c364dc46c5c992bcfaf4fee33fa13eebdf82c591fc9825aab769
TESTNET_SUDT_DEP_INDEX=0
TESTNET_SUDT_DEP_TYPE=code
TESTNET_SUDT_SCRIPT_CODEHASH=0xc5e5dcf215925f7ef4dfaf5f4b4f105bc321c02776d6e7d52a1db3fcd9d011a4
TESTNET_SUDT_SCRIPT_HASHTYPE=type

Testing Neuron

To run the tests, simply execute:

shell$ yarn test

Download Neuron Binary

If you prefer not to build from source, you can easily download the pre-built binary from releases available for Windows, Linux, and macOS.

Troubleshooting

If you encounter issues during installation or running the Neuron wallet, consider the following troubleshooting steps:

• Ensure that your Node.js and Yarn versions are compatible and up to date.
• Review the proxy and CDN settings, especially if you’re experiencing slow downloads.
• For Windows users, double-check the installation of Microsoft Visual C++ Redistributable.
• Check your environment configuration for any discrepancies.
