ERC-223 is an extension of the ERC-20 protocol, and it was created to address the ERC-20 bug by a developer named ‘Dexaran’ from the Ethereum community.
The term ERC stands for “Ethereum Request for Comment”. The ERC 223 token platform utilizes smart contracts and enables secure token transfers to a digital wallet.
Ethereum’s established tokenization standards simplify the tokenization process. Different types of tokens can be tokenized using different standards depending on the intended application.
Some of the popular Ethereum tokens include ERC-20, ERC-721, and ERC-777 standards.
Although the ERC-20 standard is widely used, it has some design flaws. One of these flaws led to the loss of tokens when they were mistakenly sent to a smart contract instead of a regular wallet. This mistake has resulted in the loss of over $3 million worth of ERC-20 tokens.
ERC-223 addresses this design flaw by allowing token transfers to smart contracts and wallets that serve the same purpose. Additionally, ERC-223 tokens are more efficient as they require only one step for transactions, unlike ERC-20 tokens.
ERC-223 retains all the original functionality while fixing the bugs found in ERC-20. It introduces enhancements and capabilities that address serious issues when interacting with other smart contracts.
The transfer function of ERC-223 includes a parameter to ensure that the destination address is a smart contract. If it is, the transaction calls the token Fallback function in the smart contract, and the tokens can be returned to the sender’s account using this function before being transferred to the smart contract.
No tokens are lost because the updated transfer function works for smart contracts as well.
Here are some benefits of the ERC-223 token:
ERC-223 can be seen as an extension of ERC-20, but only time will determine which token becomes the ultimate standard in the Ethereum ecosystem.
