As to your new product, on my end, can I cancel a policy and replace it with another one? How? Also, what if the policy holder would try to withdraw the funds even if I am still alive, although offline for a few months?
Sure. Just delete the API KEY or address from Whitelist in your binance account.
"We plan to introduce policies with deferred use, for example, one year after creation or with an indication of the start date of the policy. Thus, the heir will not be able to use the policy until this date. Or you can use any other services for deferred messages, emails, SMS."
