# Operations Control ## Allowlist Vault owners are able to create and edit lists of integrations (adapters and/or external positions). This restricts which integrations a permissioned trader can access via the vault. ### Allowed adapters Adapters are integrations which enable you to interact with various DeFi protocols. An Adapter is terminology we use to signal that interacting with this DeFi integration is being represented by a liquid, divisible, fungible token. Enabling this policy means that your vault will only be able to interact with DeFi adapter integrations that you select. Importantly, restricting your vault to only have adapter connectivity will reduce trust assumptions and give it a superior liquidity properties. ### Allowed external positions An external position is similar to an adapter integration in that it allows you to interact with external DeFi protocols. However, they differ in that they are not represented by a liquid, divisible, fungible token (eg. Compound CDPs or Uniswap v3 LP positions, Maple Lending, Aave Borrowing and Convex Voting). This policy defines which external position “types” can the vault interact with. Selecting external positions on this policy means that your vault will only be able to interact with external positions on this list. Note that if a vault is able to interact with external positions, it increases trust assumptions and introduces the potential for some risks. ### Asset disallowed list An asset disallowed list enables a vault owner to specify assets from the asset universe which are "off limits". Nobody can trade these assets from within the vault whilst they are on this list. This is a useful policy to use if you want to disallow assets with low quality price feeds being held in the vault. This can lead to inaccurate NAV pricing and possible arbitrage risk. ## Slippage stop-loss This policy is designed to limit any maliciously intended (or accidental) actions which could cause a loss to the value of the vault. It does this by limiting the value loss (i.e. slippage) that can occur via adapter actions over a “tolerance period” (a rolling 7 day period). Vault owners can define a tolerance threshold (eg. 10%). Whenever an adapter action results in slippage, that slippage amount is added to a cumulative slippage total. The accumulated slippage then diminishes over the “tolerance period duration” at a constant rate based on the fund’s chosen tolerance. This policy allows bypassing the slippage checks entirely if the adapter being called is in a Council-maintained list on the AddressListRegistry (adapters that cannot be manipulated by asset managers to steal fund value). ## Restrict asset position removal This policy exists to protect against a delegated trader un-tracking an asset in the vault such that it is no longer being accounted for. This can create incorrect valuation of vaults. This policy prevents the removal of an external position from the vault’s accounting unless its value can be considered negligible (i.e. dust). The dust threshold is maintained by the Enzyme Council. ## Restrict external position removal This policy exists to protect against a delegated trader removing an external position vault such that it is no longer being accounted for. This can create incorrect valuation of vaults. The policy prevents the removal of an external position from the vault's accounting unless a) it does not have a valid price, or b) its value can be considered negligible (i.e. dust). The dust threshold is maintained by the Enzyme Council. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
