As we all know, there are many professional terms in the blockchain industry, especially some words involving technology, which are very difficult for many investors to understand, but some common words are also something we should know, such as ERC-20 and TRC-20 mentioned in this article. When we mention these two words, we have to mention usdt. As for USDT, we all know that it is one of the currencies that enter the market, Stable currency based on 1:1 US dollar issued by Tether. Therefore, some novice investors recently asked Xiaobian, what are TRC20 and ERC-20? What are the differences between them? Then, let's follow Xiao Bian.

What do TRC20 and ERC-20 mean?

TRC20：

RC20USDT is a stable currency jointly issued by Wave Field TRON and TEDA Tether. Compared with well-known stable currencies (Omni USDT, ERC20-USDT, etc.), TRC20-USDT has significantly improved the transfer cost and transaction determination rate.

In terms of fees, TRC20-USDT can realize free transfer. The money withdrawal cost of mainstream exchanges shows that the service charge for currency withdrawal of USDT based on the Omni agreement is the most expensive, ranging from US $4-10. The service charge for ERC-20 is from US $1 to US $5, while the service charge for currency withdrawal of TRC20-USDT is 0, which means that customers can enjoy the currency withdrawal service of the exchange free of service charge.

In terms of purchase and sale determination rate, the USDT issued based on the wave field network has played the performance advantages of the third generation public chain. The TPS of the wave field network can reach over 1000 levels, and can achieve second level purchase and sale determination, which is significantly better than Omni (transfer determination must be 10 minutes to several days) and ERC20 (minutes to hours). The fast transfer rate can meet various requirements of stable currency customers and prevent the damage to investors' rights and interests due to network congestion.

ERC-20：

ERC20 is the token specification in the Ethereum ecosystem, allowing any token that completes the standard and is achieved through smart contracts to be reused from the wallet to the decentralized exchange.

For example, in the past, the credits issued by enterprises can only be used internally, and only represent the internal rights and interests of the enterprise ecosystem. With the token, it is different. For companies, enterprises can distribute certificates for financing, listing on the stock exchange (similar to listing), and encourage users to use the company's products; For the holders, according to the proportion of dividends held by the pass, the pass can be freely interchanged, buy low and sell high to earn the price difference. ERC20 has brought a unified standard for the issuance and circulation of the pass. The pass is sold, traded and exchanged in the same way, without paying attention to what the issuer of the pass uses it for (depending on the issuer) and how to complete the pass.

Any smart contract can be operated through the ERC20 standard interface as long as it complies with the ERC20 specification. This also means that Contract A, named TokenA, marked A, with the contract address of 0x000.. 0a, and Contract B, named TokenB, marked B, with the contract address of 0x000.. 0b, meet ERC20 standards; A. B are ERC20 certificates, and migration certificate A and migration certificate B have no difference in use for users.

What are the differences between TRC20 and ERC20?

1、 TRC20 Features

1. Service charge for payment... no service charge?!

yes! There is no handling charge for transferring USDT in the wave field, but the handling charge for withdrawing TRC-USDT from the exchange will still be charged (deducted by the exchange). Address example: TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t (TRC-20 contract)

2. Currently under test

Most exchanges have applied the TRC-USDT recharge, but because the TRC-USDT is still under test, the replenishment of the exchange is closed.

2、 ERC20 Features

1. The service charge type of payment is ETH

ERC-USDT, like other Ethereum Tokens, is stored in the Ethereum address. Therefore, the type of service charge to be paid for each transfer is ETH. Address example: 0xdac17f958d2ee523a2206206994597c13d831ec7 (ERC-20 contract)

2. Most exchanges are applicable to full withdrawal, and the withdrawal limit is low

Most mainstream exchanges support ERC-USDT replenishment, and you can choose to mention BTC address or ETH address when withdrawing coins. Moreover, taking fire coins as an example, ERC-USDT's minimum withdrawal limit (2USDT) is now lower than Omni USDT (200USDT).

3. It is applicable to smart contracts, and the online transaction query is faster

Unlike Omni USDT, ERC-USDT can be applied to smart contracts. All mainstream Ethereum browsers can check ERC-20 USDT transactions. Interested users can go to Tokenview's Ethereum browser to check ERC-USDT transaction details.

Speaking of this, I believe you have a certain understanding of what TRC20 and ERC-20 are and what are their differences. In general, the advantages of TRC20 can make investors feel good about investing in such stable currencies. With the halving of Bitcoin, investors are uncertain about their preference for special currencies, which aggravates investors' choice of stable currencies. Therefore, some people in the currency circle believe that the rise of TRC20 to the global top stable currency is an inevitable trend of market choice.
