After I try to send the tokens, I get this error "(error_36) Input address is not checksummed. What does that mean?" and does not send tokens. Has anyone encountered this problem? can anyone knows the solution.
Every Ethereum address has two versions. One version has some letters as uppercase characters and the other version doesnt.
As an example:
◾Non-checksummed version: 0xdecaf9cd2367cdbb726e904cd6397edfcae6068d
◾Checksummed version: 0xDECAF9CD2367cdbb726E904cD6397eDFcAe6068D
Even though both addresses use the same charachters and lead to the same place, the checksummed address is more accurate in determing if the address is a correct one.
Even though you can still use the non-checksummed address, it is recommended to use a checksummed address so that the payment gateway (MEW or an Exchange) can determine if the address you want to send the funds to is real.
