Most contracts are concerned with 1 utility/payment/app token only and wouldn't know what to do with other types. ERC223 provides a method to reject unwanted ERC223 but it does not catch unwanted ERC20. | |

| May 1, 2019 at 10:07 | comment | added | Sophie259 | I'm nearly ready to accept your solution, I just want more details because I feel like I'm missing some points. You say that ERC223 is the 1-step solution but I don't fully understand how. Is there a reference to some practical code that I can see as an example? | |
