There are two FRAX tokens on polygon and if you type FRAX in the Exchange it's impossible to tell which is which.

Native FRAX: https://polygonscan.com/token/0x45c32fa6df82ead1e2ef74d17b76547eddfaff89

Bridged FRAX: https://polygonscan.com/token/0x104592a158490a9228070e0a8e5343b499e125d0

Maybe it would be better to follow the token naming? FRAX vs FRAX (PoS).
