ERC20的简介：

ERC-20引入了可替代Token（代币）的标准，换句话说，它们具有使每个Token（代币）与另一个Token（代币）完全相同（在类型和价值上）的属性。

例如，ERC-20，Token（代币）的行为与ETH相同，这意味着任意1个遵循ERC-20规则的Token（代币）与所有其他所有Token（代币）是平等和相同的。

由Fabian Vogelsteller在2015年11月提出的ERC-20（以太坊请求注释20）是一种Token标准，在智能合约中实现了Token的API。

『一』 Are the addresses of eth and erc20 the same?

Now they are unified and have the same address.

The Erc20 deposit address and the ETH deposit address have been unified. Subsequently, you recharge Erc20 currency to the ETH recharge address, and the system will automatically identify and credit the account. At the same time, before the system upgrade, the original Erc20 currency recharge address still accepts recharge and can be credited.

USDT-ERC20 is USDT issued by Tether based on the ETH network. The deposit address is the ETH address, and deposits and withdrawals are made through the ETH network. USDT-ERC20 uses the ERC20 protocol.

In early 2018, the Ethereum network exploded in popularity, smart contracts became popular in blockchain applications, and ERC20-USDT appeared. Like Omni-USDT, using ERC20-USDT also requires payment of absenteeism fees, but the transfer speed has been significantly improved. Due to good security and fast transfer speed.

ERC20-USDT is widely accepted by the market, and TEDA, the issuer of USDT, has also begun to abandon Bitcoin Omni in favor of the more efficient Ethereum ERC20.

Introduction to ERC20:

ERC-20 introduces a standard for fungible Tokens (tokens) , in other words, they have properties that make each Token exactly the same (in type and value) as another Token.

For example, ERC-20 Tokens behave the same as ETH, which means that any Token that follows ERC-20 rules is the same as all other Tokens. are equal and the same.

ERC-20 (Ethereum Request Comment 20) proposed by Fabian Vogelsteller in November 2015 is a Token standard that implements Token APIs in smart contracts.

『二』What are the six basic functions of ERC20 tokens

In order to create an ERC20 token, you need to write down the following

Token name Token symbol Token decimal place Token quantity is the circulation contract code Verification source code By the way, ERC721 is a protocol mainly used for blockchain games. The blockchain games that you often see are basically based on ERC721.

『三』Is erc20 the Binance Chain?

No.
ERC20 is a token protocol based on Ethereum.

『四』What is Ethereum imToken support?Compliant with ERC20 tokens

Ethereum is an open source public blockchain platform with smart contract functions. It provides a decentralized virtual machine (called the Ethereum Virtual Machine) through its dedicated cryptocurrency Ether (also known as "Ether") to process peer-to-peer contracts. The concept of Ethereum was first proposed by programmer Vitalik Buterin between 2013 and 2014 after being inspired by Bitcoin. It roughly means "the next generation of cryptocurrency and decentralized application platform" and began to develop through ICO crowdfunding in 2014.
Ethereum is not just a database, it also allows you to run programs in the trusted environment of the blockchain. Ethereum has built a virtual machine called EVM (Ethereum Virtual Machine) on the blockchain. EVM allows code to be verified and executed on the blockchain, providing assurance that the code will run the same way on everyone's machine. These codes are included in smart contracts. In addition to tracking account balances, Ethereum uses the same method to save the state of the EVM on the blockchain. All nodes process smart contracts to verify the integrity of the contract itself and its outputs.

『五』 Can I receive it if I fill in the eth-erc20 address as the coin printing payment address?

Yes.
The Erc20 deposit address and the ETH deposit address have been unified. Deposit Erc20 currency to the ETH deposit address, and the system will automatically identify and credit the account. At the same time, before the system upgrade, the original Erc20 currency recharge address still accepts recharge and can be credited.
ERC20 is the token standard in the Ethereum ecosystem, allowing any token that implements the standard and is implemented through smart contracts to be reused from wallets to decentralized exchanges. The English name of Ethereum is Ethereum. It is a public blockchain platform that can be used to process peer-to-peer smart contracts. From 2013 to 2014, Vitalik Buterin proposed related concepts about Ethereum. It was not until 2014 that the promoters of Ethereum received crowdfunding funds to develop. There are four design principles of Ethereum, namely the principle of non-discrimination, the principle of modularity, the principle of universality and the principle of simplicity. The principle of non-discrimination refers to the fact that Ethereum’s network protocol supports players to create specific applications, and the platform will not be specific. Object to certain applications.

『Lu』What does it mean to choose ERC20 for withdrawing coins?

Selecting ERC20 for withdrawing coins means that the user chooses the ERC20 protocol when withdrawing coins, so the corresponding address must be filled in when withdrawing coins. Write an Ethereum address based on the ERC20 protocol. The withdrawal speed of the ERC20 protocol is relatively fast. The fee type paid is ETH. Most trading venues support deposits and withdrawals. The withdrawal limit is low. It supports smart contracts and has more detailed on-chain transaction queries.convenient. The security and transfer speed of ERC20-USDT are acceptable, and it is suitable for frequent transactions in the digital currency market. If users often do short-term transactions, it is recommended to choose ERC20-USDT first.

2. Ethereum is an open source public blockchain platform with smart contract functions. It provides a decentralized Ether virtual machine to process point-to-point contracts through its dedicated cryptocurrency Ether (ETH). The concept of Ethereum was first proposed by programmer Vitalik Buterin between 2013 and 2014 after being inspired by Bitcoin. It roughly means "the next generation of cryptocurrency and decentralized application platform" and began to develop through ICO crowdfunding in 2014. As of February 2018, Ethereum is the second-largest cryptocurrency by market capitalization, after Bitcoin.
3. Bitcoin is a P2P digital currency, proposed by Satoshi Nakamoto on November 1, 2008, and officially born on January 3, 2009. The open source software designed and released based on Satoshi Nakamoto's ideas and the P2P network built on it. Bitcoin’s transaction records are open and transparent. Peer-to-peer transmission means a decentralized payment system. Unlike most currencies, Bitcoin does not rely on the issuance of a specific monetary institution. It is generated through a large number of calculations based on a specific algorithm. The Bitcoin economy uses a distributed database composed of many nodes in the entire P2P network to confirm and record all transaction behaviors. And use cryptographic design to ensure the security of all aspects of currency circulation. The decentralized nature of P2P and the algorithm itself ensure that currency value cannot be artificially manipulated by mass production of Bitcoins. Design based on cryptography allows Bitcoin to be transferred or paid only by real owners. This also ensures the anonymity of currency ownership and circulation transactions.

『撒』 How many Ethereum coins are there in total?

The current total supply of Ethereum coins is 111,562,994 coins.
1. Ethereum is a virtual currency that appeared after Bitcoin. Although it is a virtual currency that appeared later, the development momentum of Ethereum is that the latecomers will catch up. This does not mean that Bitcoin has withdrawn. Although the trend of virtual currency has been affected, it can be explained that people are graduallyGradually accept such virtual currencies
2. Ethereum officially released and issued 72 million Ethereum digital currencies in 2015. In addition, Ethereum can generate approximately 18.72 million Ethereums through mining every year, and there is no limit to the total amount. , is infinite. When Ethereum developers launched Ethereum, they not only referred to the relevant rules of Bitcoin, but also combined some laws in finance. Taking into account the year-by-year increase in the number of investors and the increase in investor asset strength, they decided on the issuance of Ethereum. for infinity.
Extended information:
1. Ethereum (ETH for short) is a next-generation cryptographic ledger that can support many advanced functions, including user-issued currency, smart protocols, decentralized transactions and the establishment of decentralized Centralized Autonomous Organizations (DAOs) or Decentralized Autonomous Companies (DACs).
2.Ethereum (Ethereum) is a platform with smart contracts. Its biggest contribution is the establishment of standardized token usage standards, such as ERC-20, the same currency storage protocol standard, and different currency conversion standards ERC- 721. There are also various financial digital currency standard applications such as transactions, leases, transfers, etc., allowing developers to build and release the next generation of distributed applications. Ethereum can be used to program, decentralize, secure and trade anything: voting, domain names, financial exchanges, crowdfunding, corporate governance, contracts and most agreements, intellectual property, and smart assets thanks to hardware integration. Ethereum will use a hybrid security protocol, using the proof-of-work mechanism (POW) in the early stage to distribute Ethereum, and then switching to the proof-of-stake mechanism (POS). From the time of launch, 0.26x, that is, 60102216 * 0.26 = 15626576 Ether coins will be mined by miners every year. After converting to POS, the number of Ether coins produced each year will decrease.

『8』 What is erc20 chain?

erc20 is the Ethereum chain.

ERC20 is a token protocol based on Ethereum. As we all know, there are thousands of tokens on the market, and among these tokens, there are at best 18,802 ERC20 tokens, and the number of ERC20 tokens is still increasing. ERC20 can make the Ethereum block Seamless interaction between other smart contracts and decentralized applications on the chain.

ERC-20 is vital

As of October 2019, there are more than 200,000 ERC-20 compatible tokens on Ethereum’s main network (Token). ERC-20 is crucial. It defines a list of common rules that all Ethereum Tokens must adhere to.

Among these rules are how Tokens are transferred, how transactions are approved, how users access data about Tokens, and the total supply of Tokens.

『九』What is the difference between shib withdrawal erc20 and heco

What is the difference between USDT withdrawal TRC20 and ERC20?
The difference between erc20 and trc20 lies in different address styles, different networks used, and different security. In terms of address style, erc20 starts with the number 0 and a lowercase relatively low.
1. Features of TRC20
1. The handling fee for payment... No handling fee?!
Yes! There is no handling fee for transferring USDT on Tron, but there is no handling fee for withdrawing TRC-USDT on the exchange. There will still be a withdrawal fee (charged by the exchange). Address example: (TRC-20 contract)
2. Currently still under testing
Most exchanges support the deposit of TRC-USDT, but because TRC-USDT is still under testing, the exchange’s Deposits and withdrawals are closed.
2. ERC20 Features
1. The type of handling fee paid is ETH
ERC-USDT, like other Tokens on Ethereum, is stored on the Ethereum address, so every time you transfer, you need to pay The handling fee type is ETH. Address example: (ERC-20 contract)
2. Most exchanges support deposits and withdrawals, and the withdrawal limit is low
Basically, mainstream exchanges support ERC-USDT deposits and withdrawals, and you can choose when withdrawing coins. Are you referring to a BTC address or an ETH address. Moreover, taking Huobi as an example, the minimum withdrawal limit of ERC-USDT (2USDT) is currently smaller than Omni-USDT (200USDT).
3. Support smart contracts, making on-chain transaction queries more convenient
Unlike Omni-USDT, ERC-USDT can support smart contracts. ERC-20 USDT transactions can be queried in mainstream Ethereum browsers. Interested users can go to Tokenview's Ethereum browser to query ERC-USDT transaction details.
What do erc20 and trc20 mean?
1.erc20
USDT-ERC20 is USDT issued by Tether based on the ETH network. The deposit address is the ETH address, and the deposit and withdrawal are through the ETH network. USDT-ERC20 uses the ERC20 protocol.
In early 2018, the Ethereum network exploded in popularity, smart contracts became popular in blockchain applications, and ERC20-USDT appeared. Like Omni-USDT, using ERC20-USDT also requires payment of absenteeism fees, but the transfer speed has been significantly improved. Due to its good security and fast transfer speed, ERC20-USDT is widely accepted by the market. TEDA, the issuer of USDT, has also begun to abandon Bitcoin Omni and insteadSupport the more efficient Ethereum ERC20. With the recent issuance of USDT by TEDA on Ethereum, the number of ERC20-USDT has increased significantly and now exceeds 50% of the total amount of Omni-USDT. In addition to officially abandoning the Omni protocol, mainstream exchanges have also begun to support ERC20-USDT. On July 3, Binance Exchange announced that it would switch from the OMNI network to the ERC20 network. Although the USDT of the original OMNI network can continue to be recharged and credited, the USDT of the OMNI network will not be able to be withdrawn.
2.trc20
TRC20-USDT is USDT issued by Tether based on the TRON network. The deposit address is the TRON address, and deposits and withdrawals are made through the TRON network. TRC20-USDT (USDT-TRON) uses the TRC20 protocol.
In April 2019, TEDA announced the issuance of USDT based on the TRC-20 protocol on Tron, and TRC20-USDT was born. When TRC20-USDT was issued, it promised to be completely open and transparent, with zero transfer fees and transfers in seconds. Different from the first two, there is currently no handling fee for TRC20-USDT transfers, which is also a highlight of TRON. However, the current development of TRC20-USDT is not very mature and security cannot be guaranteed.

『Shi』 Are Ethereum EREUM and ERC the same channel?

Yes.
The erc20 channel means the standard interface for each token. ERC20 tokens are only a subset of Ethereum tokens. In order to be fully compatible with ERC20, developers need to integrate a specific set of function interfaces into their smart contracts. , so that operations can be performed at a high level.
