What is ERC 223?

ERC-223 is a proposed token standard for the Ethereum blockchain that aims to improve upon the ERC-20 standard, which is currently the most widely used standard for creating tokens on Ethereum

The main difference between ERC-223 and ERC-20 is that ERC-223 tokens include an additional function for handling incoming token transactions

In ERC-20, when a user mistakenly sends tokens to a contract address that does not support them, the transaction is rejected and the tokens are lost forever

However, with ERC-223, the contract can implement a function that handles incoming transactions, which prevents the tokens from being lost and provides a better user experience

ERC-223 also aims to make token transfers more efficient by reducing the amount of gas required for each transaction

With ERC-20, each token transfer requires two separate transactions, which can result in higher transaction fees and longer processing times

ERC-223 solves this problem by allowing a single transaction to transfer both tokens and data, which makes it more efficient and cost-effective

Overall, ERC-223 aims to provide a more user-friendly and efficient token standard for the Ethereum network

However, it has not been widely adopted yet, and ERC-20 remains the most widely used standard for creating tokens on Ethereum.
