🎒 Setup

Project setup

Create a new project in a fresh directory and navigate into it by running mkdir kilt-rocks && cd kilt-rocks.

The dependencies needed are the following:

• KILT SDK-JS - for KILT functionality
• dotenv - to load environment variables
• If you use Typescript and not JavaScript ts-node and Typescript - to execute TS code

Typescript

Initialize the project and install dependencies.

npm

npm init -y
npm install @kiltprotocol/sdk-js dotenv ts-node typescript

Yarn

yarn init -y
yarn add @kiltprotocol/sdk-js dotenv ts-node typescript

pnpm

pnpm init -y
pnpm add @kiltprotocol/sdk-js dotenv ts-node typescript

Javascript

Initialize the project and install dependencies.

npm

npm init -y
npm install @kiltprotocol/sdk-js dotenv

Yarn

yarn init -y
yarn add @kiltprotocol/sdk-js dotenv

pnpm

pnpm init -y
pnpm add @kiltprotocol/sdk-js dotenv

Project Folder

Typescript

Create the following remaining files and folders to end up with the folder structure below:

└─ kilt-rocks/ # project
    ├─ attester/ # all attester code
    ├─ claimer/ # all claimer code
    ├─ verify.ts # all verifier code
    └─ .env # environment variables

mkdir attester claimer && touch verify.ts .env

Javascript

Create the following remaining files and folders to end up with the folder structure below:

└─ kilt-rocks/ # project
    ├─ attester/ # all attester code
    ├─ claimer/ # all claimer code
    ├─ verify.js # all verifier code
    └─ .env # environment variables

mkdir attester claimer && touch verify.js .env

PILT Tokens

This workshop interacts with the Peregrine test blockchain, which requires you to pay for each transaction with Peregrine Kilt (PILT) tokens.

But don't worry. PILT tokens have no value, and you can request them from the faucet.

Blockchain Connection

Before using any SDK functionality, you must initialize and configure the Kilt SDK.

As this workshop uses the Peregrine Testnet you use its address whenever using the SDK to interact with the Kilt blockchain.

You do this by calling the following function:

await Kilt.connect({address})

Where address is the address of the full node you want to connect to, which for this workshop, is wss://peregrine.kilt.io.

For convenience, add the address to the .env file.

.env

WSS_ADDRESS=wss://peregrine.kilt.io

That's it for the basic setup - You're good to go!
