很多朋友在进行USDT转账的时候都会出现三种链类型，这个时候就很多人不知道具体选择哪一种，也不知道这几种链类型的区别，心里就会产生谨慎，其实这三种链类型都是可以使用的，本文简单地讲述一下这三种链类型的区别，希望对大家有所帮助。

Many friends make USDT transfers with three chain types xff0c; at this point many do not know which of these chain types xff0c is specifically chosen; xff0c xff0c xff0c in mind xff0c; in fact, these three chain types are available xff0c; this is a brief description of the three chain types xff0c; hopefully it will help everyone.

　　USDT的三种形态分别是：

The three forms of USDT are xff1a;

　　基于比特币网络的Omni-USDT，充币地址是BTC地址，充提币走BTC网络；

Omni-USDT， based on the Bitcoin network; billed address BTC & #xff0c; billed to BTC network & #xff1b;

　　基于以太坊ERC20协议的ERC20-USDT，充币地址是ETH地址，充提币走ETH网络；

ERC20-USDT，, based on the Etherno-ERC20 agreement; billed address: ETH address & #xff0c; charged currency to ETH network & #xff1b;

　　基于波场TRC20协议的TRC20-USDT，充币地址是TRON地址，充提币走TRON网络。

TRC20-USDT， based on the Spot TRC20 Agreement; billed address Tron & #xff0c; billed to Tron network.

　　1、Omni-USDT

　　2014年11月，USDT于比特币网络上诞生，于2015年2月正式上线几大主流交易所。在2018年之前，USDT的转账路径只有一条，那就是基于比特币网络的Omni-USDT。Omni-USDT存储在比特币地址上，因此每次转账的时候，需要支付比特币作为矿工手续费。Omni-USDT于比特币网络的链上，黑客攻击的成本很高，所以资产相对安全性较高。但是其交易速度非常慢，已经无法满足当今加密交易市场的需求，但很多大宗交易还是会倾向于Omni-USDT。

xff0c; USDT was born on the Bitcoin network in November 2014; xff0c; xff0c; xff0c; xff0c; xff0c; x08; xff0c; that's Omni-USDT based on the Bitcoin network. Omni-USDT is stored on the Bitcoin address xff0c; xff0c; xff0c per transfer; xff0c; xff0c; mni-USDT on the Bitconet network; xff0c; thus assets are relatively safe.

　　2、ERC20-USDT

　　2018年初，以太坊网络爆红，智能合约普及于区块链应用，ERC20-USDT出现。和Omni-USDT一样，使用ERC20-USDT同样需要支付旷工费，但转账速度有了显著的提升。由于安全性好、转账速度快，ERC20-USDT被市场广泛接受，USDT的发行者泰达公司也开始放弃了比特币Omni，转而支持更高效的以太坊ERC20。随着近期泰达公司多次在以太坊上增发USDT，ERC20-USDT的数量显著增加，目前已超过Omni-USDT总量的50%。除了官方放弃Omni协议以外，主流交易所也开始转向支持ERC20-USDT。7月3日，币安交易所宣布将由OMNI网络切换为ERC20网络，虽然原OMNI网络的USDT可以继续充值并上账，但将无法提现OMNI网络的USDT。

At the beginning of 2018, xff0c; xff0c; xff0c; ff0c; fff0c; x20-USDT for smart contracts to be widely accepted in the market; xff0c; xff0c as in Omni-USDT; xff0c for the use of ERC20-USDT; xff0c; but the speed at which transfers are made is remarkable. Due to good security, speed at which transfers are fast xff0c; rc20-USDT accepted by the market xff0c; Taida, the publisher of USDT, has also given up 50% of Omni-USUST; supports a more efficient ETA ERC20.

　　3、TRC20-USDT

　　2019年4月，泰达公司宣布在波场上发行了基于TRC-20协议的USDT，TRC20-USDT诞生。TRC20-USDT发行时承诺完全公开透明，零转账费，秒级到账。和前两者不同的是，目前TRC20-USDT转账是不收取手续费的，这也是波场打造的一个亮点。但目前TRC20-USDT的发展还不是很成熟，也无法保证安全性。

In April 2019, xff0c; Teda announced the release of USDDT，, based on the TRC-20 agreement, and the birth of TRC20-USDT. TRC20-USDT was issued with a commitment to full transparency and transparency xff0c; zero transfer fees xff0c; sec to account. The difference between the two is xff0c; xff0c, currently free of charge of TRC20-USDT transfers; xff0c; it is also a bright spot for the development of the TRC20-USDT.

　　应该如何区分？

How to distinguish #xff1f;

　　首先要明白一点：三种类型的USDT在交易所内并没有差别，但在链上是不互通的。也就是说Omn上的USDT是无法转到另外两条链上的，所以在交易所充提USDT时一定要留意地址种类。

To begin with, xff1a; there is no difference between the three types of USDT in the exchange xff0c; but on the chain is unconnected . That means that the USDT on Omn cannot be transferred to the other two chains xff0c; so in the exchange attempt the address type .

　　三者最明显的区别：

The three most obvious differences #xff1a;

　　Omni-USDT的地址是以1开头

Omni-USDT address starts with 1

　　ERC20-USDT的地址是以0x开头

ERC20-USDT address starts with 0x

　　TRC20-USDT的地址是以T开头

TRC20-USDT address starts with T.

　　那么，应该如何选择？

#xff0c; how to choose #xff1f;

　　Omni-USDT的安全性最好，但转账速度太慢。要是你有不着急交易的大额订单，可以优先选择Omni-USDT。

Omni-USDT is best secure xff0c; but transfers are too slow. If you have large orders xff0c, you can choose Omni-USDT.

　　ERC20-USDT的安全性和转账速度居中，适用于数字货币市场的频繁交易。要是你经常做短线交易，可以优先选择ERC20-USDT。

ERC20-USDT’s security and speed of transfer are at the centre & #xff0c; frequent transactions that apply to digital currency markets.

　　TRC20-USDT的转账速度最快，而且链上转账无需手续费，但安全性比较低。要是你非常在意交易速度，可以考虑TRC20-USDT，建议小额为主。

TRC20-USDT transfers are the fastest xff0c; and there is no charge on the chain transfer xff0c; but security is low. If you care very much about the speed of the transaction xff0c; you can consider TRC20-USDT， the suggestion is small.
