[Ethereum] How to resend a transaction not recognized by the network

It sounds like geth is not yet synced up.

Please type this into your geth console:

eth.getBlock("latest").number

As of this post, you should get 894332 or higher.

I get the correct output on my geth console.

> web3.fromWei(web3.eth.getBalance('0x7cacf18f931259c30a7194fa96ab3a44c38b3535'),'ether').toString(10)
"0.01"

Running this patch at the console works for me:

eth.resend = function (tx, gasPrice, gas) {
  if (gasPrice) {
    tx.gasPrice = gasPrice;
  }
  if (gas) {
    tx.gas = gas;
  }
  tx.data = tx.input;
  return eth.sendTransaction(tx);
};

I prefer to also add this convenience version:

eth.resendgwei = function (tx, gasPriceInGwei, gas) {
  if (gasPriceInGwei) {
    return eth.resend(tx, web3.toWei(gasPriceInGwei, 'gwei'), gas);
  }
  else {
    return eth.resend(tx, null, gas);
  }
};

Now, if your pending transaction is stuck because the gas price is too low, you can speed it up with:

eth.resendgwei(eth.pendingTransactions[0], 51);
