Test Network

What is Test Network?

Test Network is an open Interledger network working with test money designed for account servicing entities to test their Interledger integration.

Test Network currently includes an Interledger Test Wallet application, an e-commerce application and in the near future, a bank application.

If you are curious about the Interledger Test Wallet architecture diagram, then follow this link.

Local Development Environment

Prerequisites

• Docker
• NVM
• GateHub account in Sandbox mode

Environment Setup

# Install Node 20
nvm install lts/iron
nvm use lts/iron

# Install pnpm using Corepack
corepack enable

If you do not have corepack installed locally you can use npm or yarn to install pnpm:

npm install pnpm -g
# or
yarn install pnpm -g

For alternative methods of installing pnpm, you can refer to the official pnpm documentation.

To install dependencies, execute:

pnpm i

Environment Variables

In order for the Test Wallet and Test e-commerce playground to function, it is necessary to configure the environment variables appropriately. You must duplicate the example environment file, .env.example, into your local environment file, .env.

Note The local environment file (.env) is NOT tracked in the version control system, and should NOT be included in any commits.

Navigate to the project's root directory and enter the following command:

cp ./docker/dev/.env.example ./docker/dev/.env

Using your preferred text editor, open the ./docker/dev/.env file and configure the necessary environment variables. The GATEHUB related environment variables are necessary in order to complete Sandbox KYC, and add play money to your account. In order to have the correct variables, create a GateHub Sandbox account. Optionally you could send an email to [email protected] and request these variables.

To create a new Interledger Test Wallet account, a verification email will be sent to the provided email address. If you want to send emails within the development environment, you will need to have a personal Sendgrid account and update the following environment variables: SEND_EMAIL to true, SENDGRID_API_KEY and FROM_EMAIL. If you prefer not to send emails in the development environment, simply set SEND_EMAIL to false and use the verification link found in the Docker wallet-backend container logs to finalize the registration process for a new user.

To enable rate limiter on the wallet for security purposes you can set these environment variables: RATE_LIMIT to true and RATE_LIMIT_LEVEL. RATE_LIMIT_LEVEL has three possible values: LAX|NORMAL|STRICT, default is LAX.

Cross-currency transactions are supported. To enable this functionality, you will need to register at freecurrencyapi.com/ and update the RATE_API_KEY environment variable with your own API key. Currencies can be added in the admin environment. For example assetCode is EUR, assetScale is 2, and you will need to add an amount to liquidity.

If you would like to set up e-commerce application, you will need to create a USD payment pointer, then generate public and private key for the payment pointer in the Developer Keys found in the Settings menu of Interledger Test Wallet. You also need to update the following environment variables: PRIVATE_KEY to the generated base64 encoded private key, KEY_ID to the payment pointer key id and PAYMENT_POINTER to the created payment pointer address.

Local Playground

Navigate to the project's root directory and execute:

pnpm dev #this will start the project in hot reload mode for backend containers. Frontend containers have hot reload functionality enabled on all dev commads

other options to start the local env are:

pnpm dev:debug #backend containers will not have hot reload feature enabled but will expose and have node `--inspect` option set with wallet container debug port set to 9229 and boutique port set to 9230. Once the containers are running, you can connect your debugger (e.g., Chrome DevTools, VS Code)

and:

pnpm dev:lite #backend containers will build and run the builds, no debug and no hot reload for these containers

Upon executing the above command, the following will be available

• Interledger Test Wallet application

  • Frontend at http://localhost:4003
  • Backend at http://localhost:3003
  • Admin at http://localhost:3012

• Interledger Boutique e-commerce application

  • http://localhost:4004
