Lesson 15: account from useMoralis and seller address different

[konstantinabl]

Hi guys,

I have the following problem:
In my NFTBox.js in the nextjs-nft-marketplace I make a check if the NFT is owned by the user
const isOwnedByUser = seller == account || seller === undefined
And although seller and account should be different they are not. But the only difference is that in one address one letter is upper case and in the other it is lower case.

Printed addresses
0x1d5F0509cFd312aB892192209dCDb04B24967789

0x1d5f0509cfd312ab892192209dcdb04b24967789

I have no idea where this issue is coming from. May you help?

@konstantinabl seller address is basically coming from the moralis database and the account that you are using in metamask. see what address is in your database.

[konstantinabl]

what database do you mean?

@konstantinabl moralis

i have the same issue here. i find one solution in moralis forum:https://forum.moralis.io/t/user-addresses-are-lowercase/1601
it seems that all addresses in moralis are lowercase, we need to use lowercase before comparing them

[hamingsi]

just need toLowerCase()
