Does it support uppercase in web3.js? I write and deploy a test contract on rinkeby 0x7b84de0c31d308b42427d562306526e3eb95c825 if I change it to uppercase it return error Attempting to run transaction which calls a contract function, but recipient address 0x7b84de0c31d308b42427d562306526e3eb95c825 is not a contract address.
So I think contract address not support uppercase now.
I search like 'eth contract address uppercase' and read the wiki on github, but still not find any thing;
Can anyone give me an offical ansower ? and If it will support uppercase in future.
Provided address "0x7B84de0c31d308b42427d562306526e3eb95c825" is invalid, the capitalization checksum test failed, or its an indrect IBAN address which can't be converted.– Toknsit Toknsit Nov 29 '18 at 08:13
