This guide will help you get the Wallet Gateway up and running quickly.

Installation

Choose your preferred installation method: Global Installation (npm): Install the Wallet Gateway globally using npm:
npm install -g @canton-network/wallet-gateway-remote
After installation, you can run it from anywhere:
wallet-gateway -c ./config.json
Run with npx (No Installation): Run the Wallet Gateway directly through npx without installing (tested with Node.js v24):
npx @canton-network/wallet-gateway-remote -c ./config.json
This downloads and runs the latest version each time, useful for testing or one-off runs.

Quick Start

  1. Create a Configuration File First, generate an example configuration file: Global Installation:
    wallet-gateway --config-example > config.json
    
    npx:
    npx @canton-network/wallet-gateway-remote --config-example > config.json
    
  2. Edit the Configuration Open config.json and customize it for your environment. At minimum, you’ll need to configure:
    • Store connection: Database configuration (in-memory, SQLite, or PostgreSQL)
    • Networks: At least one Canton network with its Ledger API endpoint
    • Identity Providers: Authentication configuration for your networks
    See Configuration for detailed configuration options.
  3. Start the Gateway Global Installation:
    wallet-gateway -c ./config.json
    
    Or with a custom port:
    wallet-gateway -c ./config.json -p 8080
    
    npx:
    npx @canton-network/wallet-gateway-remote -c ./config.json
    
    Or with a custom port:
    npx @canton-network/wallet-gateway-remote -c ./config.json -p 8080
    
  4. Verify it’s Running Once started, the Wallet Gateway exposes three endpoints:
    • Web UI: http://localhost:3030 (or your configured port)
    • dApp JSON-RPC API: http://localhost:3030/api/v0/dapp
    • User JSON-RPC API: http://localhost:3030/api/v0/user
    Open the web UI in your browser to confirm it’s running.

Command Line Options

The Wallet Gateway supports the following command-line options:
-c, --config <path>          Set config path (default: ./config.json)
--config-schema              Output the config schema (JSON Schema) and exit
--config-example             Output an example config and exit
-p, --port [port]            Set port (overrides config file)
-f, --log-format <format>    Set log format: json or pretty (default: pretty)
Example: Global Installation:
# Generate config schema
wallet-gateway --config-schema

# Run with JSON logging
wallet-gateway -c ./config.json -f json
npx:
# Generate config schema
npx @canton-network/wallet-gateway-remote --config-schema

# Run with JSON logging
npx @canton-network/wallet-gateway-remote -c ./config.json -f json

Configuration Schema

To see the full JSON Schema for the configuration file, run: Global Installation:
wallet-gateway --config-schema
npx:
npx @canton-network/wallet-gateway-remote --config-schema
This outputs a complete JSON Schema that can be used for validation and IDE autocomplete support.
