Developers have adopted ERC20 as a prominent standard for new digital assets. The birth of ERC20 allows developers to create digital assets using the platform without having to write new crypto wallet code.

What is ERC20 token?

As we have seen above, ERC20 is a common technical standard for tokens operating on the Ethereum blockchain.

The identification of ERC20 tokens is very simple. That is looking at the wallet address of that token.

Disadvantages of ERC20 tokens

There are some problems that the standard ERC-20 not resolved.

In some cases, tokens may be accidentally destroyed when they are used to pay for a smart contract instead of using ETH.
