There are approximately 450,000 tokens created with this standard on the Ethereum network. The smart contract includes information on how tokens will be transferred and how transactions will be confirmed. Additionally, it provides information and rules on the total supply and data of the token that users can access.

What are the Advantages?

ERC-20 is a technical standard that ensures compatibility of tokens on the Ethereum blockchain network. It saves the project team time as it has high-quality code. In addition, this standard increases the interaction between tokens. Tokens with this standard are secure, low-cost, user-friendly, automatic, quickly invested, widely used, and high-earning cryptocurrencies. They also have high transaction flow and can withstand traffic congestion. Ethereum is the largest blockchain that supports creating tokens and Dapps. Therefore, tokens created with this standard are more easily adopted.

DeFi and NFT projects mostly create their tokens using the ERC-20 standard, causing the number of tokens to constantly increase. However, this can cause congestion, leading to a slowdown in the Ethereum blockchain. The popularity of the standard also makes it a frequent target for hackers. Creating tokens via smart contracts is easy, so there are many useless or fraudulent tokens created with this standard.
