At present,#usdtand#usdcare the two largest centralized stablecoins with the largest circulation. They have centralized institutions, are issued with US dollars and US dollar equivalents as collateral, and promise that usdt and usdc on the chain can be 1:1 Convert to U.S. dollars through the issuing institution. And they are all issued in different public chains. Currently, the largest issuance of usdt is Wavelength Network, followed by Ethernet; the largest issuance of usdc is Ethernet.

If you hold these two stablecoins for a long time, one important thing you need to pay attention to is whether the stablecoin you hold is a native stablecoin. What's the meaning?#Nativestablecoins refer to issues issued directly on the Internet by issuing institutions. In contrast, non-native stablecoins are not issued directly by issuing institutions, but are mapped from others through cross-chain bridges and are not officially recognized. of.

There is an additional layer of risk in holding non-native stablecoins for a long time, mainly the risk of cross-chain bridges. Currently, many cross-chain bridges are centralized. If there is a problem with them, it means that the stablecoins you hold may not be able to cross-chain bridges. Returning to the main network means that on the issuing institution's side, the money is counterfeit and cannot be exchanged for real money through the issuing institution.

Why are we talking about this topic? I saw the news yesterday that circle was going to issue usdc on the#maticnetwork. I realized that the usdc on matic that I had been using for a long time was not native. So I checked the official websites of circle and usdt and found that matic The two stablecoins on are bridged, not native.

From the perspective of short-term use, native and non-native stablecoins are similar, but if you want to store them for a long time, you still need to store native stablecoins from a security perspective.
