Yes you should. When did ShapeShift stop using your service? Did they explain
why?

I see that you also advertise that Gap600 is "Trusted by" Coindirect and
Coinify, both AML/KYC crypto exchanges. Obviously, with full AML/KYC
double-spends are not much of a concern. And it's not even clear that
either accepts zeroconf anyway, as I'll explain later.

On this list you claimed that:

What's the value and number of transactions that *actually* rely on your
unconfirmed transaction tools? The only category that would apply for is goods
provided immediately and irrovocably, without AML/KYC. Because it sounds like
these figures may be significantly overstated.


Re: CoinsPaid, what you say here makes it also sound like it relies on AML/KYC:

Re: Coindirect, the documentation I can find appears to say that confirmations
are required before you can use coins deposited into Coindirect:

This is repeated here as well: https://help.coindirect.com/hc/en-us/articles/4409120006546--Deposits-

Re: Coinify, the API docs don't give any indication of risk scoring or any
other Gap600 integration:
