Global Ledger

Edit online

IBM Digital Asset Haven integrates with Global Ledger, a blockchain analytics provider offering AML compliance and Know Your Transaction solutions. The platform supports more than 2,000 digital assets and delivers real-time risk scoring for transaction screening.

Setup

  1. Go to Settings > Integrations > AML in the IBM Digital Asset Haven Dashboard.
  2. Select the Global Ledger tab.
  3. Enter your Global Ledger API key.
  4. (Optional) If using an on-premises deployment, specify your custom base domain and supported blockchains.
  5. Click Save.

Outbound Transfer Prescreening

Global Ledger can screen outbound transfers before they are broadcast on-chain. To enable this, create a policy with:
  • Activity kind: Wallets:Sign
  • Rule kind: GlobalLedgerTransactionPrescreening
  • Action kind: Block, RequestApproval, or NoAction
When the policy triggers
The policy triggers when either:
  • The transaction’s risk score meets or exceeds your configured riskScoreThreshold (0–100 scale, where 100 is highest risk).
  • Global Ledger returns alerts for the transaction (alerts are configured in your Global Ledger dashboard).
When triggered, the policy approval page shows Evaluation details with the full response from Global Ledger, including risk scores and alerts.
Skip Options
The rule includes options to handle edge cases:
Option Description
skipUnscreenableTransaction Skip wallet requests that cannot be screened (for example, raw signatures)
skipUnsupportedNetwork Skip transfers to networks not supported by the integration
skipUnsupportedAsset Skip transfers of assets not supported by the integration
skipGlobalLedgerFailure Skip if the Global Ledger API request fails
When a skip option is enabled and the condition is met, the policy does not trigger and the transaction proceeds.
Webhook Events

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

Supported networks

Global Ledger supports major blockchains such as Bitcoin, Ethereum, Tron, BNB Chain, and Solana. For the complete list of supported networks and assets, see Global Ledger’s documentation.
Note: If you’re using an on-prem deployment of Global Ledger, you can specify which blockchains your deployment supports in the Dashboard integration settings.
