If you've tried adding a new token in your wallet, one thing you could notice is the form field asking for a Token Contract Address. This refers to the address location of the actual token contract that manages the logic for the tokens. It does not refer to the address that holds your own personal tokens!
To find out what this address is, we recommend looking at the token's website for more information or going on https://etherscan.io/tokens and searching directly for the name of your token.
We highly recommend double-checking these addresses on your own. From your Etherscan account, you can check your custom contract addresses by clicking on the token, which will bring you to the token page. As an example, the Orachain token page: https://etherscan.io/token/0x4c11249814f11b9346808179cf06e71ac328c1b5
