I want to call an action on a contract that is deployed on rinkeby test net. But transaction confirmation seems to take forever and I can't find it on rinkeby etherscan. Is there something wrong with my code?

let Web3= require('web3');
let web3 = new Web3 (new Web3.providers.HttpProvider("http://127.0.0.1:8545"));
var Tx = require('ethereumjs-tx');

tokenAbi = [{"constant":true,"inputs":[],"name":"mintingFinished","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"name","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"_spender","type":"address"},{"name":"_value","type":"uint256"}],"name":"approve","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"totalSupply","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"supplyLimit","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"_from","type":"address"},{"name":"_to","type":"address"},{"name":"_value","type":"uint256"}],"name":"transferFrom","outputs":[{"name":"success","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"decimals","outputs":[{"name":"","type":"uint8"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[],"name":"getAddress","outputs":[{"name":"","type":"address"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"_to","type":"address"},{"name":"_amount","type":"uint256"}],"name":"mint","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"addr","type":"address"},{"name":"unlockTime","type":"uint256"}],"name":"lockTill","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"transfersAreLocked","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"_spender","type":"address"},{"name":"_subtractedValue","type":"uint256"}],"name":"decreaseApproval","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"name":"_owner","type":"address"}],"name":"balanceOf","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[],"name":"renounceOwnership","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[],"name":"finishMinting","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"owner","outputs":[{"name":"","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"symbol","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"tokenOwner","outputs":[{"name":"","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"_to","type":"address"},{"name":"_value","type":"uint256"}],"name":"transfer","outputs":[{"name":"success","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"locked","type":"bool"}],"name":"changeTransferLock","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"_spender","type":"address"},{"name":"_addedValue","type":"uint256"}],"name":"increaseApproval","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"name":"_owner","type":"address"},{"name":"_spender","type":"address"}],"name":"allowance","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"_newOwner","type":"address"}],"name":"transferOwnership","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"anonymous":false,"inputs":[{"indexed":true,"name":"to","type":"address"},{"indexed":false,"name":"amount","type":"uint256"}],"name":"Mint","type":"event"},{"anonymous":false,"inputs":[],"name":"MintFinished","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"previousOwner","type":"address"}],"name":"OwnershipRenounced","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"previousOwner","type":"address"},{"indexed":true,"name":"newOwner","type":"address"}],"name":"OwnershipTransferred","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"owner","type":"address"},{"indexed":true,"name":"spender","type":"address"},{"indexed":false,"name":"value","type":"uint256"}],"name":"Approval","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"from","type":"address"},{"indexed":true,"name":"to","type"

const tokenAddress = '0xAfff042F602762B59442660aCDF34fdE8681D016';
var Contract = new web3.eth.Contract(tokenAbi, tokenAddress, {from: '0x6C7bc8e30cAE5409b30c16eFA458eADAaE6e6810'});

web3.eth.getTransactionCount('0x6C7bc8e30cAE5409b30c16eFA458eADAaE6e6810').then(function(nonce){

  gasLimit: 7000000,
  nonce: nonce,
  chainId: 4
}

var tx = new Tx(rawTx);
const privateKey = Buffer.from(PK, 'hex')
tx.sign(privateKey);

var serializedTx = tx.serialize();

web3.eth.sendSignedTransaction('0x' + serializedTx.toString('hex'))
.on('receipt', console.log);

})

The gasPrice is too low, try: 2000000000 (2Gwei) The gasLimit is too low, is even lower than the base price for a transaction, try increasing it (remember that the non-used gas is returned to you)

The nonce should be updated after every transaction, use:

web3.eth.getTransactionCount(address [, defaultBlock] [, callback])

Hope this helps.

    Nope, still the same problem. Transaction takes forever to execute and I can't find it on rinkeby block explorer. Here is my updated code: ' var rawTx = { to: '0xafff042f602762b59442660acdf34fde8681d016', data: trxData, gasPrice: 2000000000, gasLimit: 7000000, nonce: nonce } ' – JustinZ Dec 4 '18 at 10:01
  • can you please update the question with your new code?, also can you share the hash of the transaction that is taking forever? – Jaime Dec 4 '18 at 10:40
  • Updated the code above – JustinZ Dec 4 '18 at 11:07
  • Your nonce is still incorrect, why are you adding 2 to the value returned by the function? The transaction has a nonce that is above the current one, and will not be processed until the missing values are observed in the network. – Jaime Dec 4 '18 at 13:22
  • Updated the code and used different account. But problem remains still – JustinZ Dec 4 '18 at 13:53

Most probably, gs limit of 100 is too low. Transaction might not be getting picked-up up for inclusion on pending block.

Try increasing the gas limit.

  • I have made tx limit 999. If I make it over 999 I get 'exceeds block limit' error. Altho rinkeby gas limit is 7119155. Is it something wrong here? – JustinZ Dec 3 '18 at 16:40
  • 1. What is the Transaction hash that you get after submitting transaction ? 2. Do you increment nonce for each transaction ? – Shamit Verma Dec 3 '18 at 17:12
  • transaction hash 0x65986d6a4df8e4b8c38977795d87b82b3089c60d7ba7183c9c8768963c927efe I can't find it on the Rinkeby network. And yes, I do increment it, because otherwise, it gives me an error. – JustinZ Dec 4 '18 at 8:36
  • Do you have a local node ? Does that node provide any info? (Like eth.getTransaction(txHash) on geth console . – Shamit Verma Dec 4 '18 at 16:55
  • Yes, I have a local node. And yes node provides information about the submitted transaction with transaction hash. – JustinZ Dec 5 '18 at 7:49

I have solved the problem. The problem was that there were too many stuck transactions in the tx pool, so I had to clean them by turning my node off and deleting transactions.rlp file
