[Ethereum] How to a transaction fail

ethertransactions

Given that a transaction has

A high enough gas limit for the transaction to succeed
A high enough gas price for it to be mined
No contract calls that throws

Is there any way that transaction can fail?

Best Answer

If there's enough gas provided, with the necessary gas price, and no contract calls that throw, then it shouldn't fail.

You should also consider the case where even if a large amount of gas is provided, if the contract contains an unbounded loop, some complex computation or recursive calls, it could fail by running out of gas, even if you provide the maximum possible gas limit.

You're correct that all subsequent transactions would be refused.

So with Geth, you can rebroadcast with a higher fee (gas price) by using eth.resend (the nonce will remain the same).

eth.resend(tx, optional gas price, optional gas limit)

Example:

eth.sendTransaction({from: eth.accounts[0], to: "...", gasPrice: "1000"})
var tx = eth.pendingTransactions[0]
eth.resend(tx, web3.toWei(20, "GWei"))

Your price per gas unit is set super high -- 41 Gwei, and the limit is 7,600,027 gas units. 41 * 7,600,027 = 311,601,107 Gwei, or 0.311601107 ETH (which estimates to about $300 USD right now).

You need to lower the price per gas unit and the gas limit. The error message basically says that the transaction will fail because you don't have enough money in the transaction to cover the theoretical max gas used (which is the approx 0.31 ETH figure).
