Chainalysis

Screen inbound and outbound transactions with Chainalysis KYT for AML compliance, with automatic enforcement through DFNS policies and webhooks.

Chainalysis is the industry leader in blockchain analysis and transaction monitoring. Their KYT (Know Your Transaction) platform provides real-time risk scoring and investigative tools to help meet AML compliance requirements.

Setup

1. Open the Chainalysis integration

   In the DFNS Dashboard, navigate to Integrations, find the Chainalysis card, and click Configure.

2. Activate and enter your API key

   Toggle Activate Chainalysis Integration, then enter your Chainalysis API key.

   
3. Save

   Click Save. The integration is now active, and the Chainalysis rules become available in the policy builder.

Outbound transfer prescreening

Outbound transfers can be screened by Chainalysis before they are broadcast on-chain. Create a policy that runs the Chainalysis prescreening rule on wallet activity.

From the dashboard

1. Create a policy

   Go to Policies, click Create Policy, give it a name, and select the Wallet usage (transfer, transaction, signature) activity.

2. Select the Chainalysis rule

   On the Rule step, choose Transaction attempt prescreening (Chainalysis). Set the minimum alert level that triggers the policy (Low, Medium, High, or Severe), and optionally restrict the alert, exposure, and address categories or set a User ID template.

   
3. Choose an action and save

   Pick the action taken when the rule triggers, then review and Save. You can scope the policy to specific wallets or tags.

When the action is RequestApproval, a flagged transfer stays pending until an approver reviews it. The approval page shows the triggered policy and the reason, with the full Chainalysis evaluation under “Evaluation details”.

With the API

Create a policy with:

• Activity kind: Wallets:Sign
• Rule kind: ChainalysisTransactionPrescreening
• Action kind: Block, RequestApproval, or NoAction

When the policy triggers, the Chainalysis screening results are included in the policy.triggered webhook event.

Inbound transfer screening

Incoming transfers detected by the DFNS indexer can be screened by Chainalysis and reported to you.

From the dashboard

1. Create a policy

   Go to Policies, click Create Policy, give it a name, and select the Incoming wallet transaction activity.

2. Select the Chainalysis screening rule

   On the Rule step, choose Transaction screening (Chainalysis) and configure the alert level and categories.

   
3. Save

   Incoming screening reports results without blocking, so the action is No action. Review and Save.

With the API

Create a policy with:

• Activity kind: Wallets:IncomingTransaction
• Rule kind: ChainalysisTransactionScreening
• Action kind: NoAction

When the policy triggers, the Chainalysis screening results are included in the policy.triggered webhook event.
