Payment extensions safe?

I am worried if payment extensions are safe or not?
If it is safe then which extension would be best for upi payments?
Please provide extension if its safe.

Until your app being hacked . In such case try to create app using android studio

Always try to use activity starter if you worry about extension. It is safe. But phone pe won’t work. I hope in future play store will accept your app if you set google pay only as your upi payment

In a case of a serious hack Android studio will not help.

Both the options can be right.
depending on the developer and his/her intentions

U have to search this through community there are many extension available
