const { mcsSDK } = require('js-mcs-sdk-calibration')
const fs = require('fs')

async function main() {
  const testFile = JSON.stringify({ address: mcs.publicKey })
  const fileArray = [{ fileName: `${mcs.publicKey}.txt`, file: testFile }]

  // set up js-mcs-sdk
  const mcs = await mcsSDK.initialize({
    privateKey: process.env.PRIVATE_KEY,
    rpcUrl: process.env.RPC_URL, // process.env.BSC_RPC_URL for tbnc network
  })

  const uploadResponse = await mcs.upload(fileArray)
