To ensure the highest standards of compliance and security, Dfns is integrated with Chainalysis, the industry leader in blockchain analysis and transaction monitoring (AML / KYT). This integration allows you to automatically screen inbound and outbound transactions for connections to illicit activity, helping you meet regulatory obligations for Anti-Money Laundering (AML) and Know-Your-Transaction (KYT). Leverage real-time risk scoring and powerful investigative tools from Chainalysis directly within your Dfns workflow to protect your platform from bad actors.

​
How to set it up

To activate the integration, you need to go to Dfns Dashboard, and activate the integration from the settings, by adding your Chainalaysis API key. Once that is done, the integration is done through the Policy Engine.

Transfer Screening

​
For outgoing transfers

Outgoing transfer attempts from a given wallet can be screened by Chainalysis before they make it on chain. To achieve that, you need to create a Policy with these traits: When using policy rule ChainalysisTransactionPrescreening, the transfer attempt will be sent to Chainalysis for a KYT screening. If the screening result triggers the rule (based on the criterias you defined in the rule), then the details of the Chainalysis pre-screening results will be published in the Webhook Event policy.triggered, which is published for any policy which triggers.

​
For incoming transfers

When an incoming transfers in a wallet is picked ou by our indexer, it can be screened by Chainalysis, and reported to you if something is detected as a result. To achieve that, you need to create a Policy with these traits: When using policy rule ChainalysisTransactionScreening, the transfer attempt will be sent to Chainalysis for a KYT screening. If the screening result triggers the rule (based on the criterias you defined inthe rule), then the details of the Chainalysis screening results will be published in the Webhook Event policy.triggered, which is published for any policy which triggers.
