This development could be beneficial for decentralized cryptocurrencies, but for USDT it won’t change the fact that it is a centralized coin that is fully controlled by Tether and can be frozen at any time even if it is in a non-custodial wallet.
I really wonder what benefits Tether will gain from launching an “open source wallet development kit (WDK) that enables businesses and developers to integrate non-custodial wallets into any website or application”? I really don’t understand why a centralized company would do such a thing?
As I understand it, WDK is a toolset that allows users to create their own wallet applications instead of having to use other wallet applications available on the market. This can provide peace of mind for businesses, as they control the code and will naturally control the keys to their accounts and crypto assets.
Unfortunately, WDK currently only supports BTC and ERC20 USDT, and other tokens are still in the process of being integrated. Besides BTC, USDT is under the sole management of Tether, so WDK also doesn't provide true security for owners against asset freezing decisions from Tether. However, this risk is still very low and businesses can actually consider using this WDK for their own purposes.
