Did every step of instruction.
Sending 0 ETH with 150000 GAS and 1 GWEI to address + adding data.
But after i send ETH - i cant check it on etherscan: Sorry, We are unable to locate the Transaction entry
What the reason may be?
What wallet do you use?
In order to properly diagnose a detail explanation will require.
Maybe we need a screenshot of the error page.
