What is ERC-777?

The ERC-777 standard has several advantages. For example, it allows anyone to add new capabilities to tokens. One of which is a mixer contract for enhanced transaction secrecy or an emergency recovery mechanism that would assist you if you were to misplace your private keys.

Moreover, it operates in a similar manner to Ether because tokens are sent via the function send.

A token acquired code is stated in a contract or conventional address so that it is triggered when tokens are obtained, however, this is not the scenario with ERC-20 tokens. For instance, it does move from one smart contract to another, but only the owner of the ERC-20 tokens is altered within the smart contract. So, ERC-777 is used to avoid this redundant call.

Also, the ERC-777 employs the new ERC-820 standard, which allows access to meta-data for contracts. This also permits backward compatibility as well as functionality extensions.

Contracts interact in the same manner for both the ERC-777 protocol and ERC-20 protocol.

Along with the introduction of a new transfer mechanism that has a region called bytes, where you may attach any identification data to the transfer, it alerts the destination contract that the transfer has happened.

Even though ERC-777 had faced some privacy issues that have now been solved, just like other tokens, it can have some disadvantages. This is why better versions such as ERC-820 have been revealed.

Users can transfer tokens to any Ethereum address, which means that they can send tokens to contracts that do not support them. However, the problem is that even if the tokens are moved by hand, it is complicated to determine which tokens came from whom and who sent them back.

To put things in context, the ERC-777 tokenization standard relates to Ethereum's blockchain protocol, which specifies the types of tokens that are suitable with ETH. Furthermore, it simplifies complex token trading transactions and aids in the reduction of uncertainty around decimals, minting, and burning.

It also employs a hook, which is a distinctively powerful feature. As a result, when tokens are sent to a computer-based analytical contract, a hook mechanism is activated, which simplifies how accounts and contacts connect while receiving tokens.

ERC-777 tokens are much less likely to become trapped in a contract, which has historically been an issue with ERC-20.

ERC-777 is a standard for producing tokens on the Ethereum Blockchain, similar to ERC-20. Hooks are included in the standard. If you transfer ETH to a smart contract, it will enter ETH through hooks, which ERC-20 tokens do not possess.
