1, Omni-USDTT
in November 2014, USDT was born on the Bitcoin network, and officially launched in February 2015. Exchange. Before 2018, there was only one transfer path of USDT, which was Omni-USDT based on the Bitcoin network. Omni-USDT is stored on the Bitcoin address, so each time you transfer, you need to pay Bitcoin as a miner's fee. Omni-USDT has a high cost of hacking on the Bitcoin network chain, so assets are relatively safe. However, its transaction speed is very slow and can no longer meet the needs of today's encryption trading market, but many large transactions will still tend to Omni-USDT.
2. ERC20-USDT
In early 2018, the Ethereum network became popular, smart contracts were popular in blockchain applications, and ERC20-USDT appeared. Like Omni-USDT, using ERC20-USDT also needs to pay for absentee costs, but the speed of transfer has been significantly improved. Due to good security and fast transfer speed, ERC20-USDT has been widely accepted by the market. The publisher of USDT also began to abandon Bitcoin OMNI, and instead supports more efficient Ethereum ERC20.
As Teda has recently added USDT to Ethereum, the number of ERC20-USDT has increased significantly, and it has exceeded 50%of the total Omni-USDT. In addition to the official abandonment of the OMNI agreement, the mainstream exchanges have also begun to support ERC20-USDT. On July 3rd, the Binance Exchange announced that it would switch from the OMNI network to ERC20 network. Although the USDT of the original OMNI network could continue to recharge and check the account, it will not be able to withdraw the USDT of the OMNI network.
3, TRC20-USDT
In April 2019, Teda announced that it issued a USDT based on the TRC-20 protocol on the wave field. TRC20-USDT was born.
TRC20-USDT promises to be fully open and transparent during the release. Different from the previous two, the current TRC20-USDT transfer does not charge a handling fee. This is also a bright spot created by the wave field but the current development of TRC20-USDT is not very mature and cannot guarantee security.
Os to distinguish?
It first understanding: There are no differences in the three types of USDTs in the exchange, but it is not interoperable in the chain. That is to say, the USDT on the OMN cannot be transferred to the other two chains, so you must pay attention to the type of address when charging the USDT.
The most obvious differences between the three:
Omni-usdt's address starts with 1
ERC20-USDT's address is 0x.
So how should I choose?
Omni-usdt is the best safety, but the transfer speed is too slow.
If you have a large order that is not in a hurry, you can choose Omni-USDT priority.
ERC20-USDT's security and transfers are in the middle, which is suitable for frequent transactions in the digital currency market.
If you often do short-term transactions, you can choose ERC20-USDT.
TRC20-USDT's transfer speed is the fastest, and the chain transfer is not required, but the safety is relatively low.
If you care about the speed of transaction, you can consider TRC20-USDT. It is recommended to be small. Billions of USDTs have been issued on the wave field. Safety is actually possible.
