1. Origin of ERC-20
Tokens

2. The creation of the ERC-20 Tokens generator stems from the idea of ​​Fabian
Vogelsteller , one of the creators of GitHub and Vitalik Buterin. This idea got
approval on November 19, 2015 . This idea was part of the Ethereum
Improvement Proposal (EIP) program.
The name of ERC comes from Ethereum Requests for Comments or in
Spanish, Request for Comments for Ethereum . For its part, the number 20
after ERC comes from the EIP number where the idea is proposed.
Currently ERC-20 tokens represent one of the most used types of tokens in
the crypto ecosystem, in fact, the number of ERC-20 tokens that exists is
extremely extensive.

3. What is an ERC-20 token?
In the world of cryptocurrencies , one of the most important concepts is the
ERC-20 Token creator . In case you don't know exactly what this concept is,
don't worry, in this article we will tell you everything about how it works .
In short, an ERC-20 token is a smart contract based on an already
established infrastructure with the aim of facilitating the implementation of
various functions in the Ethereum blockchain. ERC-20 tokens help
developers create new projects more easily. Among the options that this
smart contract facilitates is that of creating coins on the Ethereum block
chain.

4. What characterizes the
ERC-20 token?

5. As we already know, ERC-20 tokens differ from the rest due to their
extensive adaptation capabilities, however, achieving this is not an
easy task since for this they must comply with a certain basic
structure that will allow the user to take full advantage of their
potential. Next we will see certain characteristics that distinguish
them.
● Name or identifier plus an associated symbol . These two
values ​​are necessary since it is the way to differentiate the
tokens between them.
● They are able to manage basic economic aspects of their issue .
By this we mean data such as total issue system or decimal
precision.

6. ● It presents an interface through which the address balances of the token
owners can be controlled and reviewed. Through this interface we can
know the total balance of funds that belong to a certain address.
● Management of the transfer system . The token must be able to control
the transfer system natively. This is because the token has the ability to
issue fund transfers.
● Withdrawals of funds from one address. The token can autonomously
manage partial withdrawals from a certain address.

7. How ERC-20 tokens are stored and transferred
The tokens are associated with the account that has them, but not directly in
the blockchain, but through the smart contracts that govern them (which, in
turn, are stored in the Ethereum blockchain ).
Any transfer of ownership of ERC-20 tokens involves making use of their smart
contract, and requires some gas , that is, a small amount of ETH to pay for our
use of the blockchain, in this case for executing a smart contract. ( Gas is also
paid for ETH transfers .) This means that in order to use or move our tokens,
we also need to have at least a small amount of ETH in our Ethereum address.

8. How to view, receive and send ERC-20
tokens
To check the tokens we have, send and receive them, we need a wallet that
has support for these types of tokens. The most common are
MyEtherWallet and MetaMask.
Remember that no one can retrieve your keys for you when you use these
wallets because they are completely private, so if you open a new address
make sure to take note of your seed phrase. In case you already have an
ETH address that you want to use, you can also open or import it.
