If users wish to track ERC20 token transactions, they are required to put the token contract’s address into the "ERC20 Token Contract" field. The token contract of an ERC20 token can be found on Etherscan. Both the wallet address and the token contract address of the ERC20 token must be entered if users wish to see that specific ERC20 token’s transactions linked with the wallet address.

For example, if a user wanted to track UPP transactions involving a particular wallet, he or she is required to enter the wallet address in the appropriate field and the UPP token’s contract address as well.
