I have deposit some coins in ForkDelta using Metamask. Everytime I want to withdraw the coin, the transaction always failed. I tried to increas the gas price but the problem remains the same. Does anyone here experience the same thing? What did you do to resolve the issue? Thank you in advance.
Gas price is not a thing that can make your transaction to fail. If gas price is to low transaction will wait for days to be calculated by blockchain but will never be failed. Low gas limit may be reason for that.
It works like this: gas price gives your transaction priority to be first in line to be comuted
Gas limit is number shows maximum amount of computing units blockchain should spend beafore throwing "fail". Its made to prevent wrong code beeing computing in loop for days for thousends of dolars for 1 transaction.
Jump to your transaction in etherscan.io and if Gas Limit: f.e 37300 is equal to Gas Used By Txn: f.e 37300 than gas limit was too low. Try to increase it but remeber that transaction cost will be higher.
