USDT转账手续费哪个低？一文看懂USDT三种链类型
USDT transfers?
近期很多粉丝问USDT转账那么多链，用那个好，那个手续费比较低，今天就把常用的几个链做个普及。USDT是目前使用最广泛的稳定币，目前市值排名第四，流通市值2440亿左右。USDT是由Tether公司发行，由美元支持，比率为1：1。，很多人在使用USDT转账时会出现三个链类型，分别是OMNI、ERC20、TRC20，那么，这几种转账方式有什么区别呢？哪个手续费最低？
Many fans have asked USDT to transfer so many chains in recent times, using that, which is a relatively low charge, to spread the usual ones today. The USDT is the most widely used stable currency, currently ranked fourth, with a market value of around $244 billion. The USDT is issued by Tether, supported by the dollar, with a ratio of 1:1. Many people use USDT transfers with three chain types: OMINI, ERC20, TRC20, so what is the difference between these modes of transfer?
USDT常用的一共有三种链，分别是基于比特币网络的OMNI协议、以太坊网络的ERC-20协议和TRX(波场)网络的TRC-20协议。三种类型的USDT在交易所内并没有差别，但在链上互不兼容、不能相互转账。也就是说OMNI上的USDT是无法转到另外两条链上的，所以在交易所充提USDT时一定要链链对应。USDT-OMNI（基于比特币网络的USDT）
There are three kinds of chains commonly used by USDT, one based on the OMNI protocol of the Bitcoin network, the Ethernet ERC-20 protocol and the TRC-20 protocol of the TRX network. The three types of USDT are not different in the exchange, but they are incompatible with each other and cannot be transferred to each other. That is to say, the USDT on the OMNI cannot be transferred to the other two chains, so the chain must be matched when the exchange fills up the USDT.
USDT-OMNI诞生于2014年，充币地址是BTC地址，充提币走BTC网络。因为转账需要通过BTC网络，因此每一笔转账需要支付少量的比特币作为矿工费。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。USDT-ERC20（基于以太坊网络的USDT）
USDT-OMNI was born in 2014 at the address of the BTC, where the money is charged to the BTC network. Because transfers need to go through the BTC network, a small amount of bitcoin is required for each transfer. OMINI-USDT has a high cost of hacking on the link to the Bitcoin network, so assets are relatively secure. But its transactions are slow enough to meet the demands of today's crypto-trading market, but many large transactions tend to favour OMINI-USDT.
2018年初，以太坊网络开始普及，基于以太坊网络的USDT应用而生。USDT-ERC20需要支付GAS（也就是ETH）作为转账手续费。与USDT-OMNI相比，USDT-ERC20的转账速度有了明显提升。由于安全性好、转账速度快等特点，USDT-ERC20开始被市场广泛接受。
At the beginning of 2018, popularization began with the Taiwan network, based on the USDT application of the Taiwan network. USDT-ERC20 is required to pay the GAS (i.e., ETH) as a transfer charge. Compared to USDT-OMNI, the speed of transfers from USDT-ERC20 has increased significantly. Because of the security and speed of transfers, USDT-ERC20 has become widely accepted in the market.
USDT-TRC20（基于波场网络的USDT）
USDT-TRC20 (USDT based on the Wavefield Network)
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。
In April 2019, Teda announced the launch of the TRC-20-based USDT, TRC20-USDT, on the battlefield. TRC20-USDT was released with a commitment to full transparency, zero transfer fees, and second-class payouts. Unlike the previous one, currently TRAC20-USDT transfers are free of charge, which is a highlight of the wave.
关于冷钱包转账费用的说明
屯币党放在冷钱包的币种，提币到交易所，转账手续费由矿工收取，手续费在转账时用户可自行设置，手续费越高，转账速度越快。这是因为矿工会优先打包手续费高的转账。
The Tuenco Party is located in the currency of the cold wallet, where the money goes to the exchange, where the fees are charged by the miners, the user is free to set the charges at the time of the transfer, and the higher the fees, the faster the transfer. This is because the mining union gives priority to the transfer of the fees.
USDT-OMNI本来转账收取BTC作为手续费，为什么交易所会收取USDT?
USDT-OMNI would have transferred to charge BTC as a handling fee, and why would the exchange charge USDT?
这是为了简化用户操作，交易所收取USDT后，再兑换成比特币作为支付矿工的手续费，用户无需自己支付比特币，USDT-ERC20网络收取GAS的道理也是一样的。
This is in order to simplify user operations, when the exchange collects USDT and converts it into bitcoin as a charge to pay the miners, the users do not have to pay bitcoin on their own, and the same is true for the USDT-ERC20 network, which receives GAS.
转账时到底选择哪个链呢？哪个手续费最低呢？
Which chain does the strong choose when making transfers? Which is the least expensive?
USDT-OMNI安全性最好，转账速度慢，手续费高，推荐在大额转账时使用。
USDT-OMNI is the best security, transfers are slow and fees high, and is recommended for use in large transfers.
USDT-ERC20安全性与转账速度中等，手续费中等，推荐在中等额度转账时使用。
USDT-ERC20 has a moderate security and transfer rate and a moderate handling fee, which is recommended for use in intermediate transfers.
USDT-TRC20安全性较低，转账速度最快，没有手续费，推荐小额转账时使用。
USDT-TRC20 is less secure, transfers are fast, fees are not available, and small transfers are recommended for use.
平常充提币还是建议分批小额操作，注意风险。在币圈如果有什么问题，可以多提问交流，大家共同学习。
