# Vault Security Considerations

When selecting a vault, there are several essential factors liquidity providers should keep in mind:

<details>

<summary>Who is the Fusion vault's Atomist?</summary>

IPOR Fusion allows [Atomists](/build-on-fusion/architecture-overview/what-is-an-atomist.md) to run their public or private strategies and others to participate in profits. When selecting a vault, apart from APYs you may want to consider who is "behind the wheel" of the vault. This can be found on the web app interface in the "Atomist" column.

> ***Note**: The Atomists own the Fusion vaults. For vault-specific questions, please contact the relevant Atomist in their dedicated channel on the IPOR Protocol Discord server, under the Atomist Support category.*

<summary>What type of withdrawal method does the Fusion vault employ?</summary>

For certain strategies, such as leveraged looping or staking, it may not be prudent or possible to move assets quickly or cost-effectively. Depending on the vault's strategy, the Atomist may enable instant or scheduled withdrawals. This is particularly important if you need to access your liquidity promptly without waiting for the vault to make funds available. To learn more about the type of withdrawals, please refer to the [Withdrawing section](/fusion-for-liquidity-providers/user-guide/withdrawing.md).

<summary>What strategy is the Fusion vault implementing?</summary>

One of the most important things to check is the strategy the vault is using. The easiest way to check the strategy is to look at the Fusion vaults page. You can learn more about each strategy in the [Fusion vault types](/fusion-for-liquidity-providers/what-is-a-fusion-vault/fusion-vault-types.md) section.

<summary>What is the timelock for vault changes?</summary>

Although the vaults themselves are not upgradable, many of the settings can be modified by the [Atomist](/build-on-fusion/architecture-overview/what-is-an-atomist.md). Every change is subject to a minimum timelock set by the vault owner. The minimum timelock value indicates the amount of time you have from the moment the Atomist proposes a change to the vault's settings (such as changing the [Fuse](/build-on-fusion/architecture-overview/what-is-a-fuse.md) configuration) until it is implemented.

</details>

<details>

<summary>What is a Fusion vault's Risk Rating?</summary>

All IPOR Fusion vaults will soon receive independent risk ratings from [Xerberus](https://www.xerberus.io/), marking the industry's first dedicated vault risk rating system.

Liquidity providers can quickly assess each vault's risk at a glance using the familiar credit-style rating scale (e.g., AAA, AA, A, BBB).

In addition, every Fusion vault will feature a direct link to a comprehensive risk rating report prepared by Xerberus. Liquidity providers are strongly encouraged to review this report in detail before depositing funds.<br>

<details>

<summary>How to get notified about strategy changes by the Atomist?</summary>

IPOR Fusion does not provide a notification system for proposed vault changes. However, each Atomist has a dedicated channel in the IPOR Labs Discord server. It's recommended that you join the channels for all Fusion vaults where you have funds to stay up to date on announcements from the [Atomists](/build-on-fusion/architecture-overview/what-is-an-atomist.md).
