Answer 1

TKssrn5v8ephdmJbh7UYaUeoR4L1d4ZXds address is in base58 format, you'll need to convert it into hex format.

Using your example, you can change greet function to take an address argument.

    function greet(address _address) public payable returns (uint8) {
        TRC20 t = TRC20(_address);
        ...

You can then convert the address from base58 format to hex format using tronWeb's to hex function. tronweb.address.toHex('TKssrn5v8ephdmJbh7UYaUeoR4L1d4ZXds')
