A rule is a safety check within a policy. When a specific operation (the trigger) occurs, the rule determines the outcome for that operation. Rules let you tailor requirements to individual operations — such as withdrawals or user management — instead of relying on the default rule alone. A rule can also carry a condition that narrows when it applies. See Conditional rules for how conditions and outcomes fit together.

Outcomes

Every rule resolves to one of two outcomes. Anchorage Digital first selects the rule that matches the operation, then applies that rule’s outcome. Quorum sets a pool of eligible approvers, the number of approvals required, and any sub-quorums. Sub-quorum is an optional attachment to a Quorum. It allows you to select a pool of required approvers, the number of approvals required from that group, and a name. If a certain rule contains a quorum and a sub-quorum, it means that any in the quorum is eligible and may approve the operation, but the quorum formation is only complete once the sub-quorum is met. Block rejects the operation instead of gating it. No quorum forms, no approver is notified, and the operation is never submitted for signing. When a rule blocks an operation, Anchorage Digital tells you which rule triggered it, so you know what to change. The action stays available in the interface, so you’ll see the block when you review the operation before submitting it. Blocked operations aren’t visible to the rest of your organization (just by the user who attempts them), apart from governance operations and withdrawals initiated through the API, which will be shown as rejected under Operations.

Where Block is available

Block is a vault policy outcome only. Rules on your administrator policy always resolve to quorum, so organization-level operations such as user management can’t be blocked this way. Setting a vault policy’s default Any vault operation rule to Block rejects every operation in the vaults that policy covers. Pair it with a conditional rule above to let specific cases through — see Adding a conditional rule, or Example policy setups for worked configurations.
A default rule set to Block stops every vault operation the policy governs, including withdrawals your team may depend on. Add the conditional rule that allows your intended operations before you switch the default rule to Block.

Managing rules

Adding a rule

1

Navigate to the policy

Tap Settings, then Policies, and select the specific policy you want to edit (admin or vault).
2

Add a new rule

Tap Rules, Edit to enter the policy edit mode, then select Add rule.
3

Configure the rule

Fill in the following fields, then tap Done:
  1. Operation — Select the specific operation type this rule will control (e.g., Withdraw, User management).
  2. Quorum — Tap Quorum is to select the pool of users allowed to approve this operation.
  3. Approvals required — Define the number of approvals required from that quorum pool.
  4. Sub-quorum (Optional) — Tap Add sub-quorum to enforce stricter security, requiring a set number of approvals from a specific subgroup before the general quorum can be met.
4

Finalize

Back on the Rules screen, the new rule is tagged New. Tap Continue, review your settings, and tap Save changes. You will be prompted to submit biometric approval — quorum approval is required.
Operations not covered by specific rules will automatically follow the default Any vault operation or Any admin operation rule.

Adding a conditional rule

A conditional rule pairs a condition with an outcome, and is evaluated before the policy’s base rule.
1

Navigate to the policy

Tap Settings, then Policies, and select the vault policy you want to edit.
2

Add the conditional rule

Tap Rules, Edit to enter the policy edit mode, then select Add rule.
3

Set the operation and condition

Under For, select the operation, then select Add condition. Conditions are only available for Withdrawal rules for now.Select the condition type Destination, then choose the destinations this rule applies to: any trusted address, in any vault using this policy, or both.
4

Choose the outcome

Under Then, select Quorum is to require approvals, or Block to reject matching operations outright. For Quorum, set the eligible approvers and the number of approvals required, as with any other rule, and add a sub-quorum if needed.
5

Finalize

Tap Continue, review your settings, and tap Save changes. Follow the prompts to submit biometric approval — quorum approval is required.
Sub-quorum is an optional attachment to a Quorum. It allows you to select a pool of required approvers, the number of approvals required from that group, and a name. If a certain rule contains a quorum and a sub-quorum, it means that any in the quorum is eligible and may approve the operation, but the quorum formation is only complete once the sub-quorum is met.
A conditional rule must sit above the base rule for the same operation. The interface only allows adding a condition to the topmost rule, so ordering is handled for you.

Editing a rule

Save changes

Tap Continue, review the updated rule configuration, and tap Save changes. Follow the prompts to submit biometric approval — quorum approval is required.

Deleting a rule

You cannot delete the default Any vault operation or Any admin operation rules. These serve as the baseline safety net for your organization. When a custom rule is deleted, that operation type immediately reverts to following the applicable default rule.
1

Navigate to the policy

Tap Settings, then Policies, and select the relevant policy.
2

Delete the rule

Tap Rules, Edit to enter the policy edit mode, then tap the options menu (…) next to the rule you want to remove and select Delete rule.
3

Save changes

Tap Continue, then Save changes. Follow the prompts to submit biometric approval — quorum approval is required.

Base quorum members

The base quorum defines the pool of users — admins or operators — eligible to approve a specific operation within a policy.

Editing base quorum members

1

Navigate to the policy

Tap Settings, then Policies, and select the relevant policy (admin or vault).
2

Open the rule

Save changes

Sub-quorums

Sub-quorums add an additional security layer to a rule. They ensure an operation cannot be completed unless a specific number of approvals are received from a designated group (e.g., “2 approvals from the Legal Team”). Multiple sub-quorums can be added to any rule.
Sub-quorum members are always selected from the base quorum, so every sub-quorum approver is also part of the base quorum.
