① 支付宝怎么充值usdt

要使用支付宝充值USDT。
需要先在支付宝中搜索并下载“USDT钱包”应用。然后，在USDT钱包中选择“充币”，选择“支付宝转账”方式，输入充值金额和USDT钱包地蚂粗址，确认后系统将收到充值请求。
接着，需要在支付宝中完成转账，填写接收方USDT钱包地址和充值金额，支付宝系统将会对该笔转账进行审核和处理。一旦审核通过和完成转账，USDT便会转入您的USDT钱包，充值就成功了。需注意，不同平台和地区的规定和限制可能有所不同，建议仔细了解相关规则后槐物伍进行铅或操作。

② 数字货币领域的USDT是什么货币

泰达币（USDT）是一种将加密货币与法定货币美元挂钩的虚拟货币，是一种保存在外汇储备账户、获得法定货币支持的虚拟货币。
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，致远也将会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。
USDT的三种形态分别是：
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；
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；
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。
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。
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。
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。
应该如何区分？
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。
三者最明显的区别：
Omni-USDT的地址是以1开头
ERC20-USDT的地址是以0x开头
TRC20-USDT的地址是以T开头
那么，应该如何选择？
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。
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。
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。

③ 区块链支付系统开发公司，USDT承兑支付

区块链技术具有去中心化、信息不可篡改、集体维护、可靠数据库、公开透明五大特征，在支付方面有着透明、安全、可信的天然优势。作为引领全球产业变革的新技术，区块链支付已然成为当下的热点。

区块链承兑支付应用模式其实是利用区块链网络，将传统金融机构、外汇做市商、流动性提供商等加入支付网络，构建成为支付网关。通过支付网关，可以将区块链上数字资产流动与现实中的法定货币相连接，实现法定资产可以转换为区块链上的数字资产，便于后续的支付转账。

目前135在整个3055市面8032上USDT主要有两个用途：

一是作为代币去交易数字货币；

二是在数字货币价格下跌的时候购买进行避险保值，避免数字资产暴跌造成损失。目前在大部分交易平台都可以购买USDT，用户可以持有USDT进行币币交易，购买比特币、以太坊等币种。另一方面，用户也可以通过币币交易将手中的数字货币兑换成USDT，然后在场外兑现成法币套现。

区块链支付系统开发产品的角色：

1、用户：需要解决入金的平台，平台对接USDT支付系统后，平台用户和和普通支付流程一样可直接使用某宝、某信和卡等其他支付方式进行支付即可。

2、承兑商：持有币或者是持有资金的单位或个人，承兑商收到支付平台的自己后，对支付平台支付相对应的USDT。

3、运营平台：支付平台运营方，主要打理平台维护事项，以及处理用户与承兑商支付过程中出现的一些问题。

区块链支付系统可以解决哪些问题？

1.可以给自己在运营的项目平台中接入支付系统板块，比如C2C承兑商交易板块。自己做承兑商解决入金这块。

2.如果没有做承兑商的实力或者担心会触发Bank风控，可以选择找已有的支付平台或者承兑平台接入他们的支付，或者是场外交易平台跟他们合作。不过这种有利有弊。

3.如果有实力可以选择自己做区块链支付平台系统，不仅可以解决自己已有的项目入金问题。还可以给市面上的其他需要支付的平台或项目给他们对接。

④ 关于USDT的一点实用小科普

想必每一位币东们都有试过去交易所买过不少辣鸡、山寨、CX、空气币了。

除了一些主流的加密货币如BTC、ETH、EOS交易对外，都会看见另一种稳定币，即USDT。

以法币本位看，USDT是一种比较方便小韭菜们入金兑换其它加密货币的一种方式。因为更容易看到底跌了涨了。

那么到底什么是USDT呢？

USDT是Tether公司推出的基于稳定价值货币美元（USD）的代币Tether USD（下称USDT），号称1USDT=1美元，也就是锚定美元。方便用户可以随时使用法币对其进行1:1兑换。

我们不知道Tether公司有没有严格遵守1:1准备金保证，发一枚就去银行存1美金。目前来看幺蛾子不少，不管它到底会不会雷暴，USDT也还是目前最主流的稳定币之一，你不服也不行，该用还得用，悠着点就是了。既然早晚得出事，我们也只能中午的时候偷偷用了。

扯了大半天，今天主要讲的是关于USDT的种类。

没错，USDT运行到今天，已经不仅仅在一个区块链网络上运行了。一个不留神你的USDT很容易就打水漂了。

USDT目前有运行在三个区块链网络里，其中包括OMNI、ERC20、还有TRC20。它们分别对应于比特币网络、以太坊网络、以及波场网络。

2014年，USDT是首先在比特币区块链上基于OMNI Layer协议发行的。从此获得先发优势一局夺得大半个加密货币的稳定币市场。

2018年，以太坊网络上，基于ERC-20协议发行的USDT正式发行。

2019年，同样在波场网络中，通过TRC20协议发行了波场版本的USDT，也就是USDT-TRON20。

这三个版本的稳定币USDT-OMNI（美元）、USDT-ERC20（以太坊）、USDT-TRC20（波场）是采用不同的协议，属于不同的区块链网络。

最重要的是，它们之间是不兼容的，并不能互相转账。

划重点：

重要的事情说三遍。

那么怎么区分它们是不同网络呢？很简单，就看地址开头。

USDT-OMNI（比特币网络）地址是以1开头

USDT-ERC20（以太坊）地址是以0x开头

USDT-TRC20（波场）地址是以T开头

切记，别再转错了。

那么关于优劣方面，由于OMNI是基于比特币网络的，其安全系数比较高，而且支持更多的交易所，基本上所有交易所上线的第一个USDT版本都会是OMNI版本的，如果只有一个版本的那就是它了。

除此之外，我们考虑的另一个因素就是转账的速度，OMNI的速度很慢，以太坊版本的USDT-ERC20速度上会有一些提高，矿工费有多有少，视拥堵程度。个人觉得如果速度没有很大的提升，而转账费用也没有足够的优势的话，用的人应该不多，目前看也是如此。

来自波场版本的USDT-TRC20号称零转账费，秒级到账，目前接入的交易所貌似也不多。如果真的体验有更大的提升相信也有部分用户选择。

相较于USDT这种黑历史很多，幺蛾子也多，早晚雷暴的稳定币，个人还是建议早点换其它诸如Dai之类的去中心化的稳定币好过。

⑤ USDT支付接口开发方案

想要做一套区块链支付接口？那么首先需要了解以下几点：

1.对区块链行业有一定的基础了解，这样也能知道用什么币来做，币可以到哪里去交易等其他一些相关知识问题。

2.区块链承兑商。区块链支付需要使用一些承兑商来做账户轮训和资金分流，所以还需要从区块链行业找寻一些从事平台承兑的人。

3.团队。想一套区块链平台也是要人员去运营维护的，所以也需要安排相应的人来做，团队齐全这块就比较重要了。

区块链支付系统有用户和商户两种版本。

区块链支付系统相比传统支付系统有什么区别呢？

传统支付流程：用户—汇出机构-银行-中间行-中间行-银行-收款机构-用户/商户。

区块链币支付系统流程：用户—（支付BTC/ETH等币）—区块链支付—（结算USDT/CNY/USD）—用户/商户。

什么是承兑商？

承兑商：持有币或者是持有资产的团队企业或个人，主要在区块链承兑支付平台中做承兑商角色，也就是收款方解决出入金，是整个支付平台中的核心角色。当然也有很多平台自己也会做平台承兑商。

区块链支付如何解决行业痛点？

1.“币走通道，钱走线下”新模式，平台、商户不直接接触法币

2.以承兑商来做收款方，可实现资金分流处理解决入金问题？

3.承兑商采用账户轮询，可实现即时到账，T+0结算

4.虚拟币作为支付方式，可扩大市场业务如境外市场

5.虚拟币资金区块链可查，交易信息可追溯，安全可靠

6.支付平台与商户收币更安全、账户不存在被冻结的问题

用户：是对为虚拟币有一定了解的普通消费者使用，除了管理虚拟币外，通过对接合作的线上或者线下商户，直接可以在区块链支付系统进行支付。

商户：商家版主要是为加盟运营平台的商户提供结算管理，商户可以是线上商城或者线下实体店。

USTD支付系统，虚拟币区块链承兑商支付系统开发，清算系统结算系统，区块链支付系统开发，OTC承兑商支付系统开发 ，虚拟币交易平台开发（币币撮合、C2C、OTC、合约等），企业级区块链应用基础BAAS平台、金融交易系统等高端软件产品研发，源中瑞通过深挖行业痛点，不断激活产品潜力与价值。

⑥ 币易上的BTC、USDT、ETH、BCH、LTC是什么意思

BTC、USDT、ETH、BCH、LTC的意思分别是：

1、BTC

比特币（BitCoin），概念最初由中本聪在2009年提出，根据中本聪的思路设计发布的开源软件以及建构其上的P2P网络。比特币是一种P2P形式的数字货币。点对点的传输意味着一个去中心化的支付系统。

2、USDT

泰达币，是一种将加密货币与法定货币美元挂钩的虚拟货币，是一种保存在外汇储备账户、获得法定货币支持的虚拟货币。

3、ETH

以太坊，是一个开源的有智能合约功能的公共区块链平台，通过其专用加密货币以太币（Ether）提供去中心化的以太虚拟机（Ethereum Virtual Machine）来处理点对点合约。

4、BCH

比特币现金，是由一小部分比特币开发者推出的不同配置的新版比特币。

2017年8月1日20：20分，比特币现金开始挖矿，每个比特币投资者的账户上将出现与比特币数量等量的比特币现金（BCH）。

5、LTC

莱特币（Litecoin），简写：LTC，货币符号：Ł；是一种基于“点对点”(peer-to-peer)技术的网络货币，也是MIT/X11许可下的一个开源软件项目。它可以帮助用户即时付款给世界上任何一个人。

⑦ USDT跑分系统是什么

以前跑分用的都是微信或支付宝的二维码，用户收到一笔款子，扣除自己的点位再给商家打回去，而随着央行的政策不断的收紧，各位可以看到，微信和支付宝首先在东南亚地区，包括越南，柬埔寨等国家进行风控，微信帐号和支付宝帐号莫名被封，导致大量的平台无法进行收款，他们没办法收款就等于封锁了他们的出路，于是这些平台就用USDT来操作，在开始讲解之前，首先介绍一下USDT是什么。

那么从上面的图片内容得知，USDT是一种稳币，顾名思义，他的价值波动不大，这就为各大平台提供了非常好的收款方式。

所以以前传统的收款方式，就变成了这种USDT收款的方式，那么看到这里就应该明白，USDT跑分是一种非常可靠，安全的方法。也是目前主流的操作方法。当然，为了让大家避免上当，在这里要鉴别一些资金盘，那么资金盘有哪些特点呢？

第1点：收益高

这些资金盘为了套路更多的人上船，他们承诺的收益都非常可观，有的甚至能达到万200，这是非常值得警惕的。

第2点：活动多

资金盘平台为了拉新，推出一大堆的活动，如免费激活，免费送积分等等。

第3点：交易量大

资金盘的交易量非常大，可能一笔交易就是几千USDT，那么普通的玩家真正去玩的玩家，不都是100，200的充吗？

⑧ USDT跑分系统是什么看这个项目最近挺火的，想了解下

USDT跑分百分百是资金盘，我自己就被骗了8000，目前账号登不上了，上级还在发朋友圈推广，可恶，骗我的那个叫U World打开显示的是全球支付，我要曝光他们，免得更多人受骗，图片就是他们软件的图标，看到这个马上远离，USDT跑分千万不要碰，他们的朋友圈都是作假的

⑨ USDT是什么货币要怎么兑换人民币

USDT是泰达币，无法兑换成人民币。《关于开展为非法虚拟货币交易提供支付服务自查整改工作的通知》辖区内各支付机构开展自查整改工作，严禁为虚拟货币交易提供服务，并采取有效措施防止支付通道用于虚拟货币交易。

泰达币是一种将加密货币与法定货币美元挂钩的虚拟货币。每一枚泰达币都会象征性的与政府支持的法定货币关联。泰达币是一种保存在外汇储备账户、获得法定货币支持的虚拟货币。该种方式可以有效的防止加密货币出现价格大幅波动，基本上一个泰达币价值就等1美元。

2018年1月16日，在全球价值排名前50的加密货币中，大多数的数字虚拟加密货币都遭遇了价格大幅下跌，唯独泰达币价格逆势上涨。泰达币的价格为1.04美元，比前一天上涨3.23%，总市值为16.9亿美元。除了泰达币之外，包括比特币、以太坊、莱特币等绝大多数虚拟货币，都经历的大幅下跌。

(9)秒USDT系统扩展阅读：

2017年，监管部门发布的《关于防范代币发行融资风险的公告》中曾明确指出，各金融机构和非银行支付机构不得开展与代币发行融资交易相关的业务。各金融机构和非银行支付机构不得直接或间接为代币发行融资和“虚拟货币”提供账户开立、登记、交易、清算、结算等产品或服务，不得承保与代币和“虚拟货币”相关的保险业务或将代币和“虚拟货币”纳入保险责任范围。

中国互联网金融协会发布《关于防范变相ICO活动的风险提示》呼吁，广大消费者和投资者应认清相关模式的本质，增强风险防范意识，理性投资，不要盲目跟风炒作。此前，区块链技术一度受到多家上市公司和资本市场追捧，但也引来了是否过度炒作和“踩红线”的质疑。

① How to recharge USDT with Alipay

You need to use Alipay to recharge USDT.
You need to search and download the "USDT Wallet" application in Alipay first. Then, select "Deposit" in the USDT wallet, select the "Alipay transfer" method, enter the recharge amount and the rough address of the USDT wallet, and the system will receive the recharge request after confirmation.
Next, you need to complete the transfer in Alipay, fill in the recipient's USDT wallet address and recharge amount, and the Alipay system will review and process the transfer. Once the review is approved and the transfer is completed, USDT will be transferred to your USDT wallet, and the recharge will be successful. It should be noted that the regulations and restrictions of different platforms and regions may be different. It is recommended that you carefully understand the relevant rules before proceeding with the lead or operation.

② What is USDT in the digital currency field?

Tether (USDT) is a virtual currency that links cryptocurrency to the legal currency US dollar. It is a currency kept in foreign exchange reserves. Accounts, virtual currencies backed by fiat currencies.
Many friends will see three types of chains when making USDT transfers. At this time, many people don’t know which one to choose, and they don’t know the differences between these chain types, so they feel cautious. In fact, All three chain types can be used. Zhiyuan will also briefly describe the differences between these three chain types, hoping to be helpful to everyone.
The three forms of USDT are:
Omni-USDT based on the Bitcoin network, the deposit address is the BTC address, and the deposit and withdrawal are through the BTC network;
ERC20 based on the Ethereum ERC20 protocol -USDT, the deposit address is an ETH address, and deposits and withdrawals are via the ETH network;
Based on TRC20-USDT based on the TRC20 protocol, the deposit address is a TRON address, and deposits and withdrawals are via the TRON network.
1. Omni-USDT
In November 2014, USDT was born on the Bitcoin network and was officially launched on several major exchanges in February 2015. Before 2018, there was only one transfer path for USDT, and that was Omni-USDT based on the Bitcoin network. Omni-USDT is stored on a Bitcoin address, so every time you transfer, you need to pay Bitcoin as a miner fee. Omni-USDT is on the Bitcoin network chain, and the cost of hacking is very high, so the asset is relatively secure. However, its transaction speed is very slow and cannot meet the needs of today's encryption trading market. However, many large transactions will still tend to Omni-USDT.
2. ERC20-USDT
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 transferAccount 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 in favor of 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.
3. TRC20-USDT
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.
How to distinguish?
First of all, we need to understand one thing: there is no difference between the three types of USDT in the exchange, but they are not interoperable on the chain. In other words, USDT on Omn cannot be transferred to the other two chains, so you must pay attention to the address type when depositing and withdrawing USDT on the exchange.
The most obvious difference between the three:
Omni-USDT’s address starts with 1
ERC20-USDT’s address starts with 0x
TRC20-USDT’s address starts with T
So, how to choose?
Omni-USDT has the best security, but the transfer speed is too slow. If you have large orders that you are not in a hurry to trade, you can choose Omni-USDT first.
ERC20-USDT has average security and transfer speed, and is suitable for frequent transactions in the digital currency market. If you often do short-term transactions, you can choose ERC20-USDT first.
TRC20-USDT has the fastest transfer speed, and there is no handling fee for on-chain transfers, but the security is relatively low. If you are very concerned about transaction speed, you can consider TRC20-USDT, and it is recommended to focus on small amounts.

③ Blockchain payment system development company, USDT acceptance payment

Blockchain technology has five characteristics: decentralization, non-tamperable information, collective maintenance, reliable database, and openness and transparency. It has the natural advantages of transparency, security and credibility in payment. As a new technology leading global industrial changes, blockchain payment has become a hot topic at the moment.

The blockchain acceptance payment application model actually uses the blockchain network to add traditional financial institutions, foreign exchange market makers, liquidity providers, etc. to the payment network to build a payment gateway. Through the payment gateway, the flow of digital assets on the blockchain can be connected with the legal currency in reality, so that legal assets can be converted into digital assets on the blockchain to facilitate subsequent payment transfers.

Currently USDT has two main uses in the entire market:

One is as a token to trade digital currencies;

The other is in digital currency When currency prices fall, buy them for hedging purposes to avoid losses caused by the collapse of digital assets. Currently, USDT can be purchased on most trading platforms. Users can hold USDT for currency transactions and purchase currencies such as Bitcoin and Ethereum. On the other hand, users can also exchange the digital currency in their hands into USDT through currency-to-crypto transactions, and then cash it out into legal currency over the counter.

The role of blockchain payment system development products:

1. Users: need to resolve the deposit platform. After the platform is connected to the USDT payment system, platform users can use the same payment process as ordinary You can pay directly using other payment methods such as Xinbao, Xinxin and cards.

2. Acceptor: A unit or individual that holds coins or funds. After the acceptor receives the information from the payment platform, it pays the corresponding USDT to the payment platform.

3. Operation platform: The payment platform operator mainly handles platform maintenance matters and handles some problems that arise in the payment process between users and acceptors.

What problems can the blockchain payment system solve?

1. You can connect yourself to the payment system section of the project platform you operate, such as the C2C acceptor transaction section. Be your own acceptor to handle the deposit issue.

2. If you do not have the strength to be an acceptor or are worried about triggering bank risk control, you can choose to find an existing payment platform or acceptance platform to connect their payment, or cooperate with an over-the-counter trading platform . However, this has advantages and disadvantages.

3. If you have the strength, you can choose to build your own blockchain payment platform system, which can not only solve your existing project deposit problems. You can also connect them with other platforms or projects on the market that require payment.

④ A little practical knowledge about USDT

Presumably every currency owner has tried to buy a lot of spicy chicken, copycat, CX, and air coins on the exchange.

In addition to some mainstream cryptocurrencies such as BTC, ETH, and EOS trading pairs, you will also see another stable currency, USDT.

From a legal currency perspective, USDT is a more convenient way for investors to deposit funds and exchange them for other cryptocurrencies. Because it’s easier to see the bottomUp.

So what is USDT?

USDT is Tether USD (hereinafter referred to as USDT), a token based on the stable value currency U.S. dollar (USD) launched by Tether. It is known as 1USDT=1 U.S. dollar, which is anchored to the U.S. dollar. It is convenient for users to exchange it 1:1 with legal currency at any time.

We don’t know if Tether strictly abides by the 1:1 reserve guarantee, and goes to the bank to deposit 1 US dollar after sending one. There are a lot of things going on at the moment. Regardless of whether it will be a thunderstorm or not, USDT is still one of the most mainstream stablecoins at present. It’s okay if you don’t accept it. You have to use it when you need it, so just take it easy. Since something would happen sooner or later, we could only use it secretly at noon.

After talking for a long time, today I mainly talk about the types of USDT.

That’s right, USDT is no longer just running on a blockchain network today. If you are not careful, your USDT can easily be wasted.

USDT is currently running in three blockchain networks, including OMNI, ERC20, and TRC20. They correspond to the Bitcoin network, the Ethereum network, and the Tron network respectively.

In 2014, USDT was first issued on the Bitcoin blockchain based on the OMNI Layer protocol. Since then, it has gained the first-mover advantage and captured most of the cryptocurrency stablecoin market.

In 2018, USDT based on the ERC-20 protocol was officially issued on the Ethereum network.

In 2019, also in the TRON network, the TRON version of USDT, namely USDT-TRON20, was issued through the TRC20 protocol.

These three versions of stablecoins USDT-OMNI (USD), USDT-ERC20 (Ethereum), and USDT-TRC20 (TRON) use different protocols and belong to different blockchain networks. .

The most important thing is that they are incompatible and cannot transfer funds to each other.

Highlights:

Say important things three times.

So how to distinguish them as different networks? It's very simple, just look at the beginning of the address.

The USDT-OMNI (Bitcoin network) address starts with 1

The USDT-ERC20 (Ethereum) address starts with 0x

The USDT-TRC20 (Tron) address starts with T

Remember, don’t make the wrong transfer again.

As for the pros and cons, since OMNI is based on the Bitcoin network, its security factor is relatively high and it supports more exchanges. Basically, the first USDT version launched by all exchanges will It is the OMNI version. If there is only one version, this is it.

In addition, another factor we consider is the speed of transfer. OMNI is very slow. The speed of the Ethereum version of USDT-ERC20 will be improved somewhat. How much is the mining fee? , depending on the degree of congestion. Personally, I feel that if the speed is not greatly improved and the transfer fee is not advantageous enough, not many people will use it, and this is still the case at present.

The TRON version of USDT-TRC20 claims to have zero transfer fees and is available in seconds. It seems that there are not many exchanges currently connected to it. If the experience is really improved, I believe some users will choose it.

Compared to USDT, a stablecoin that has a lot of bad history, a lot of mistakes, and thunderstorms sooner or later, I personally recommend that it be better to switch to other decentralized stablecoins such as Dai as soon as possible.

⑤ USDT payment interface development plan

Want to make a blockchain payment interface? Then you first need to understand the following points:

1. Have a certain basic understanding of the blockchain industry, so that you can also know what coins to use, where the coins can be traded, and other related knowledge question.

2. Blockchain acceptor. Blockchain payment requires the use of some acceptors for account rotation and fund diversion, so it is also necessary to find some people from the blockchain industry who are engaged in platform acceptance.

3. Team. Thinking of a blockchain platform also requires personnel to operate and maintain it, so corresponding people need to be arranged to do it. It is more important to have a complete team.

The blockchain payment system has two versions: user and merchant.

What is the difference between the blockchain payment system and the traditional payment system?

Traditional payment process: user - remitting institution - bank - intermediary bank - intermediary bank - bank - collecting institution - user/merchant.

Blockchain currency payment system process: user—(pay BTC/ETH and other currencies)—blockchain payment—(settlement USDT/CNY/USD)—user/merchant.

What is an acceptor?

Acceptor: A team, enterprise or individual that holds coins or assets. It mainly plays the role of acceptor in the blockchain acceptance payment platform, that is, the payee handles deposits and withdrawals, which is the entire branchThe core role in the payment platform. Of course, there are also many platforms that also act as platform acceptors themselves.

How does blockchain payment solve industry pain points?

1. The new model of "coins go through channels and money goes offline", the platform and merchants do not have direct contact with legal tender

2. With the acceptor as the payee, you can Realize fund diversion processing to solve deposit problems?

3. The acceptor adopts account polling, which can realize instant payment and T+0 settlement

4. Virtual currency can be used as a payment method to expand market business such as overseas markets.

5. The virtual currency funds can be checked on the blockchain, and the transaction information can be traced, safe and reliable

6. It is safer for payment platforms and merchants to collect coins, and there are no frozen accounts. Problems

Users: It is used by ordinary consumers who have a certain understanding of virtual currency. In addition to managing virtual currency, they can directly pay on the blockchain through online or offline merchants that cooperate with each other. The system makes the payment.

Merchant: The merchant version mainly provides settlement management for merchants who join the operation platform. The merchant can be an online mall or an offline physical store.

USTD payment system, virtual currency blockchain acceptor payment system development, clearing system settlement system, blockchain payment system development, OTC acceptor payment system development, virtual currency trading platform development (coin currency Matchmaking, C2C, OTC, contracts, etc.), enterprise-level blockchain application basic BAAS platform, financial transaction system and other high-end software product development, Yuanzhongrui continuously activates product potential and value by digging deep into industry pain points.

⑥ What do BTC, USDT, ETH, BCH, and LTC mean on Biyi?

The meanings of BTC, USDT, ETH, BCH, and LTC are respectively:

BitCoin, a concept originally proposed by Satoshi Nakamoto in 2009, is an open source software designed and released based on Satoshi Nakamoto’s ideas and a P2P network built on it. Bitcoin is a P2P form of digital currency. Peer-to-peer transmission means a decentralized payment system.

2. USDT

Tether is a virtual currency that links cryptocurrency to the legal currency US dollar. It is a currency kept in a foreign exchange reserve account. , a virtual currency backed by legal currency.

3. ETH

Ethereum is an open source public blockchain platform with smart contract functions. It provides decentralized blockchain through its dedicated cryptocurrency Ether. Ethereum Virtual Machine to handle point-to-point contracts.
