  2. npm install
  3. npm run build
  4. Create dev.js in /config folder and paste the following content to the .js file
module.exports = {
  PORT: 3000,
  KUSAMA_WSS: 'wss://kusama.api.onfinality.io/public-ws',
  POLKADOT_WSS: 'wss://polkadot.api.onfinality.io/public-ws',
  API_1KV_KUSAMA: 'https://kusama.w3f.community',
  API_1KV_POLKADOT: 'https://polkadot.w3f.community',
