It is much more stable than corporate signature and will not be easily cancelled, so this is why most APP developers choose to use super signature.
Super-signature can be done in the developer center, directly select public pool or private pool, and purchase the number of super-signature devices.
At present, most developer service platforms have two choices when providing super-signatures, one is private pool, and the other is public pool.
The so-called public pool means that the developer service platform provides personal developer account+signature tools, which is what we generally call super signature.
Correspondingly, private pool means that the platform only provides signature tools, while the developer account is provided by the customer himself.
Generally speaking, the price of the signature platform is open and transparent, so you can compare the prices in many places before making a choice.
