const web3 = new Web3('https://rinkeby.infura.io/')
// Get transaction details
const trx = await web3.eth.getTransaction(txHash)
// Get current block number
const currentBlock = await web3.eth.getBlockNumber()
// When transaction is unconfirmed, its block number is null.
// In this case we return 0 as number of confirmations
return trx.blockNumber === null ? 0 : currentBlock - trx.blockNumber
