Asset-backed loans

Let your clients borrow against their digital assets without selling them, while Anchorage Digital prices the collateral and monitors loan-to-value in real time. You register the loan and respond to margin events; Anchorage Digital handles continuous risk monitoring so you don’t have to build it yourself.

How it works

Create a collateral package

When you approve a loan, create a collateral package specifying the pledgor (your end client), the pledged assets, and the loan-to-value thresholds that should trigger a warning, a margin call, or a critical alert.

Record loan activity

As the loan progresses, record activity: the initial pledge, any top-ups or margin returns, and the eventual payoff.

Monitor loan-to-value

Anchorage Digital continuously prices the pledged assets and calculates loan-to-value in real time, alerting you as thresholds are approached or crossed.

Respond to threshold breaches

When a threshold is breached, respond directly — for example, requesting a margin return — or, if pre-configured, let Anchorage Digital take an agreed action automatically as collateral manager.

Loan collateral can be held in the same subaccount as your client’s tradable funds, so you don’t need a separate account structure to offer asset-backed loans alongside custody and trading. For the full collateral management concepts — terminology, package states, configured actions, pricing methodology, and liquidation mechanics — see Atlas collateral management. This page covers the wealth-management-specific integration flow only.

Whether you or Anchorage Digital handles collateral unlock and liquidation depends on whether Anchorage Digital is configured as collateral manager for your program. Confirm this during setup.

Integration steps

These calls require the Manage Collateral Packages and Read vault activity API permissions. POST requests also require request signing.

Step 1: Set up the collateral record

POST /v2/collateral_management/packages Specify the pledgor, the pledged assets, and the loan-to-value thresholds that trigger a warning, margin call, or critical alert.

curl --request POST \
     --url https://api.anchorage-staging.com/v2/collateral_management/packages \
     --header 'Api-Access-Key: [API Key]' \
     --header 'Api-Signature: [Signature]' \
     --header 'Api-Timestamp: [Timestamp]' \
     --header 'accept: application/json' \

      "priceSource": "COINBASEPRO"
    }
  ],

    "action": "NONE"
  },
  "critical": {
    "ltv": "0.85",
    "warningLtv": "0.80",
    "returnToLtv": "0.70",
    "defaultNotice": true,

  }
}'

{
  "packageId": "9c3e5a1f-2b4d-4e6a-8f7c-1d5b9a2e4c6f"
}

Step 2: Register the loan

POST /v2/collateral_management/exposures

curl --request POST \
     --url https://api.anchorage-staging.com/v2/collateral_management/exposures \
     --header 'Api-Access-Key: [API Key]' \
     --header 'Api-Signature: [Signature]' \
     --header 'Api-Timestamp: [Timestamp]' \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data '{
  "collateralPackageID": "9c3e5a1f-2b4d-4e6a-8f7c-1d5b9a2e4c6f",
  "clientReferenceId": "your-loan-id-001",
  "type": "LOAN",
  "priceStrategy": "MID",
  "assetTrackingConfig": {
    "asset": { "type": "ANCHORAGECUSTODY", "assetType": "BTC" },
    "liquidationPriority": 1
  }
}'

{
  "exposureId": "4f8b6d2a-9e1c-4a3f-b7d5-2c8e6a4f1b9d"
}

Step 3: Record the initial pledge

Record the collateral deposit against the package, and the loan principal against the exposure.

curl --request POST \
     --url https://api.anchorage-staging.com/v2/collateral_management/operations \
     --header 'Api-Access-Key: [API Key]' \
     --header 'Api-Signature: [Signature]' \
     --header 'Api-Timestamp: [Timestamp]' \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data '{
  "type": "COLLATERAL_PACKAGE",
  "typeId": "9c3e5a1f-2b4d-4e6a-8f7c-1d5b9a2e4c6f",
  "action": "INITIAL_DEPOSIT",
  "asset": { "type": "ANCHORAGECUSTODY", "assetType": "BTC" },
  "quantity": "1.5",
  "idempotentId": "your-loan-id-001-deposit-1"
}'

curl --request POST \
     --url https://api.anchorage-staging.com/v2/collateral_management/operations \
     --header 'Api-Access-Key: [API Key]' \
     --header 'Api-Signature: [Signature]' \
     --header 'Api-Timestamp: [Timestamp]' \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data '{
  "type": "EXPOSURE",
  "typeId": "4f8b6d2a-9e1c-4a3f-b7d5-2c8e6a4f1b9d",
  "action": "INITIAL_FUNDING",
  "asset": { "type": "ANCHORAGECUSTODY", "assetType": "USD" },
  "quantity": "50000",
  "idempotentId": "your-loan-id-001-funding-1"
}'

Step 4: Monitor loan-to-value

GET /v2/collateral_management/packages/{packageId} Returns currentLtv, state (HEALTHY, MARGIN_CALL, CRITICAL, and other values), packageValue, and exposureValue. Alerts fire automatically by email and webhook as the thresholds set in Step 1 are crossed — see Email and webhook notifications.

Step 5: Respond to a threshold breach

Request a margin return once the package enters the MARGIN_RETURN state:

Request

curl --request POST \
     --url https://api.anchorage-staging.com/v2/collateral_management/packages/9c3e5a1f-2b4d-4e6a-8f7c-1d5b9a2e4c6f/requests/margin-return \
     --header 'Api-Access-Key: [API Key]' \
     --header 'Api-Signature: [Signature]' \
     --header 'Api-Timestamp: [Timestamp]' \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data '{
  "assetAmounts": [
    { "assetTypeID": "BTC", "value": "0.2" }
  ],
  "idempotencyKey": "your-loan-id-001-margin-return-1",
  "useGasStation": false
}'

Or, once your client tops up collateral in response to a margin call:

Request

curl --request POST \
     --url https://api.anchorage-staging.com/v2/collateral_management/operations \
     --header 'Api-Access-Key: [API Key]' \
     --header 'Api-Signature: [Signature]' \
     --header 'Api-Timestamp: [Timestamp]' \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data '{
  "type": "COLLATERAL_PACKAGE",
  "typeId": "9c3e5a1f-2b4d-4e6a-8f7c-1d5b9a2e4c6f",
  "action": "TOP_UP",
  "asset": { "type": "ANCHORAGECUSTODY", "assetType": "BTC" },
  "quantity": "0.3",
  "idempotentId": "your-loan-id-001-topup-1"
}'
