# Policy Packs \[Use Newton policy packs to enforce risk, compliance, and oracle checks before vault actions execute.]

Newton vault policy packs combine Rego policy logic with policy data oracles. The oracle gathers the external data needed for a decision, then the Rego policy evaluates that data against the vault's configured parameters.

In the Newton dashboard, use **Explore Data Oracles** to browse available data oracles, inspect the data they provide, and add the relevant oracle to a policy. Vault policy packs can combine multiple oracles, so a single vault action can be checked against risk, compliance, and market data before it is approved.

The open-source policy packs live in [newt-foundation/newton-policy-packs](https://github.com/newt-foundation/newton-policy-packs). Data providers can follow the repo's [CONTRIBUTING guide](https://github.com/newt-foundation/newton-policy-packs/blob/main/CONTRIBUTING.md) to add a pack that other developers can reuse in Newton-powered applications.

For more detail on how packs work, how they are implemented, and how to build policies from them, see [Policy Packs](/developers/guides/policy-packs).

:::note
The canonical deployment source is [`newton-policy-packs/deployments.json`](https://github.com/newt-foundation/newton-policy-packs/blob/main/deployments.json). The table below is a production-address snapshot for common curator workflows; use `deployments.json` for stage environments, WASM CIDs, deploy dates, and future redeploys.

## Available Packs

| Policy pack | Use it for |
| --- | --- |
| [Vaults.fyi Vault Risk Rating](/developers/vaults/policies/vaultsfyi) | Gating actions on APY, TVL, risk score, allocation changes, critical flags, and corruption status |
| [Chainalysis Address Screening](/developers/vaults/policies/chainalysis) | Screening addresses for sanctions, high-risk categories, and configured blocklists |
| [Webacy Depeg Risk](/developers/vaults/policies/webacy) | Monitoring pegged-token depeg risk for manager-action gates |
| [RedStone Oracle Divergence](/developers/vaults/policies/redstone) | Stopping actions when market data is stale, divergent, or persistently outside thresholds |

## Composing Policy Packs

Vault policy packs are most useful when combined. For example, a regulated yield vault might require:

* Webacy depeg-risk checks for pegged-token exposure
* Chainalysis sanctions screening for the depositor address
* Vaults.fyi risk checks before accepting additional capital
* RedStone oracle divergence checks before curator reallocations

The result is a vault whose rules are explicit, inspectable, and enforced before execution.
