 ### What is ERC-223? {#what-is-erc223}
 
-The ERC-223 is a standard for fungible tokens, similar to the ERC-20 standard. The key difference is that ERC-223 defines not only the token API but also the logic for transferring tokens from sender to recipient. It introduces a communication model that allows token transfers to be handled on the recipient's side.

 The API of ERC-223 token is similar to that of ERC-20, so from UI development point of view there is no difference. The only exception here is that ERC-223 tokens may not have `approve` + `transferFrom` functions as these are optional for this standard.
