i did a sendrawTransaction on ropsten and got out of gas, despite contract is shown on etherscan. i sent again with enough gas and now contract address is 0x0. What i did wrong ? here is the link to etherscan https://ropsten.etherscan.io/address/0x000ab857d04871672516292412e1e9ea887c652f where transaction can be viewed

  • It appears to be a bug, you are better reporting it to etherscan so they can fix it.

  • Do you have the code you are using to send the transaction? Can you try sending a similar transaction to another testnet? like rinkeby or a private testnet.

    seems to be an ethkey issue. ethkey at the moment seems not to be able to sign a contract tx correctly Commented Apr 26, 2018 at 4:54

1 Answer 1


it is indeed an ethkey issue, ethkey at the moment is not able to sign a contract tx correctly, using eth_sendTransaction, where eth itself signs the tx, a contract address is generated
