Does erc20 have to be on Ethereum

1. A virtual currency with a wallet doesn't mean it's more professional and advanced. The existence of digital currency wallet is the premise of currency existence. Currency without wallet can be identified as fraud
mainstream digital currencies such as bitcoin, Puyin, Laite, Ethereum and dogcoin all exist in wallets, and wallets existed before the release of such currencies.

2.

in order to create erc20 token, you need to write down the following contents

1. token name
2. token symbol
3. token decimal
4. number of tokens is in circulation
5. Contract
6. code verification source code

in addition to erc20, there are erc20, erc721, erc223, erc621, erc827, But for erc721, by the way, erc721 is a protocol mainly used for blockchain games. The blockchain games you often see are basically based on erc721

3. I personally suggest and recommend VJC. After all, Ethereum has been around for some time, and many investors have already owned it. However, Yutong chain is different. It has just been launched on the stex. Exchange platform for less than a month, and other trading platforms have not yet been launched. This is enough to prove that there is still a lot of purchasing power and the price is not high. The current price is more than $1.

4. After giving birth to the baby, the body is more empty at the beginning. It is suggested to adjust after a while. Generally, it will be two or three months after returning to the previous state. The center of confinement is relatively better

5. No, the road printing protocol needs to be supported by a token API mechanism similar to erc20 and a blockchain smart contract to operate normally.

6. No, the road printing protocol needs the token API mechanism similar to erc20 and the support of blockchain smart contract to work normally.

7. No, I can't. let's switch to other ways

Rc20 token standard (erc20 token standard) is a standard used to create token through Ethereum. According to the erc20 specification, a smart contract can be written to create a "interchangeable token". It is not mandatory, but following this standard, the token created can interact with many exchanges, wallets, etc. it has now been widely accepted by the instry

erc20 token standard was first proposed by Ethereum developer Fabian vogelsteller in the open source community. Later, Ethereum founder vitalik (known as "V God") wrote the first version of the document, which was called "standardized contract API" at that time_ Contract_ APIs

following erc20 token standard, smart contracts can be written. The token methods it needs to implement include: optional name, symbol, decimals, balance of, transfer, transfer from, approve, and allowance. The event responses it needs to implement include transfer, approve

in addition to erc20, Ethereum also focuses on erc721. Different from erc20, erc721 is a non fungible token standard (NFT)

The general syndromes of

erc20 are interchangeable and homogeneous, while the general syndromes of erc721 are not interchangeable and heterogeneous; Erc20 can be subdivided infinitely, while erc721 can not be subdivided because its minimum unit is 1

in June 2018, erc721 was officially accepted by Ethereum community and became the final standard. The popular cryptokitties followed the erc721 standard
