# Hapi

This is a crate that helps implement the use of the [HAPI protocol](https://hapi-one.gitbook.io/hapi-protocol/) in your smart contract on Near blockchain.

The crate has an AML structure that stores:

- account_id: AccountId - the address of the [aml contract](https://github.com/HAPIprotocol/near-proxy-contract);
- pub aml_conditions: UnorderedMap<Category, RiskScore> - a map of categories and corresponding risk levels that you will add.

>Note
>
>If the risk level was not set for some categories, then the risk level for the category **All** is used, which is set during initialization.
