-The ERC-223 is another standard for fungible tokens, like the ERC-20. The key difference is that ERC-223 defines not only the token API, but also the logic of how tokens should be transferred from sender to recipient and introduces a communication model that allows token transfers to be handled on the recipients side.

+ERC-223 addresses some limitations of ERC-20 and introduces a new method of interaction between the token contract and a contract that may receive the tokens. There are few things that are possible with ERC-223 but not with ERC-20:
 
-- Token transfer handling on the recipient's side. Recipient can detect that an ERC-223 token is being deposited.
-- Rejection of improperly sent tokens. If a user sent ERC-223 tokens to a contract that is not supposed to receive tokens then the contract can reject the transaction and the tokens will not be lost.
-- The transfer of ERC-223 tokens may contain metadata, which allows arbitrary information to be attached to the token transactions.

+ERC-223 is a token standard that implements an API for tokens within smart contracts. It also declares an API for contracts that are supposed to receive ERC-223 tokens. Contracts that do not support the ERC-223 Receiver API cannot receive ERC-223 tokens, preventing user error.
 
 If a smart contract implements the following methods and events it can be called an ERC-223 compatible token contract. Once deployed, it
 will be responsible to keep track of the created tokens on Ethereum.

 ### How can we make a deposit to this contract? {#contract-deposits}
 
-We can simply call the `transfer(address,uint256)` or `transfer(address,uint256,bytes)` function of the ERC-223 token and tell it to transfer some tokens to the address of the `RecipientContract`. That's it.

 ### What will happen if we transfer an ERC-20 token to this contract? {#erc-20-transfers}
 
-The ERC-20 standard supports two methods of transferring tokens: `transfer` function and `approve + transferFrom` pattern. This is not possible to make a deposit with `transferFrom` function as the `RecipientContract` does not have any functions that subsequently call `transferFrom`. If an ERC-20 token is sent with `transfer` function to the address of the `RecipientContract` then unfortunately the tokens will be transferred from the sender's address to the address of the `RecipientContract` but the transfer will not be recognized i.e. `Deposit()` event will not be fired and `deposits` value will not change. There is also no way to filter or prevent unwanted ERC-20 deposits that are made with the `transfer` function.

+## Limitations {#limitations}
+
+While ERC-223 addresses several issues found in the ERC-20 standard, it is not without its own limitations:
+
+- Adoption and Compatibility: ERC-223 is not yet widely adopted, which may limit its compatibility with existing tools and platforms.
+- Backward Compatibility: ERC-223 is not backward compatible with ERC-20, meaning that existing ERC-20 contracts and tools will not work with ERC-223 tokens without modifications.
+- Gas Costs: The additional checks and functionalities in ERC-223 transfers may result in higher gas costs compared to ERC-20 transactions.
