Basics
The easiest way to check an account is to use the isKYC method. It checks a given address, making sure it has a valid KYC. It has been audited recently for AML sanctions, and it has none.
For example, if you want to check whether a specific address verifies all these properties, you can call:
isKYC(<ADDRESS>)Trait IDs
Every user has a trait that identifies its country of origin using the ISO-32166. For example, if an individual is a citizen of the USA, the trait with ID 840 will be set. The following traits will be used to verify additional flags on a user identity.
KINTO_ADMIN_WALLET
0
US_ACCREDITATION
1
USA
840
...
...
Using the following call method, you can quickly check if a user has any trait. For example, if you want to check whether a specific address is an accredited investor in the US, you can use:
hasTrait(<ADDRESS>, 1)Sanction IDs
The numerical country code will key the sanction IDs according to https://en.wikipedia.org/wiki/ISO_3166-1_numeric.
For example, to check whether a user has any sanctions in the US:
isSanctionsSafeIn(<ADDRESS>, 840);State Functions
