# Token features

Source: https://docs.settlemint.com/docs/operators/token-features
Operator how-to pages for the eleven DALP token features, including which instrument templates attach each feature and how to configure their parameters.



The DALP platform supports eleven token features. Instrument templates attach a subset of these features to a new asset; the [system templates catalog](/docs/operators/asset-creation/system-templates) lists which features each template attaches.

This section covers the operator how-to per feature: what the feature does, which templates use it, what parameters the operator configures during creation, and how the feature behaves during day-to-day servicing. For the architecture and contract reference, see [token features architecture](/docs/architects/components/token-features).

## How features attach [#how-features-attach]

Features attach when the Asset Designer deploys an asset from a template. The platform reads the template's `requiredFeatures` list, validates the [composition rules](/docs/architects/components/token-features/feature-constraints) (dependencies and mutually-exclusive pairs), and applies the resulting feature set during deployment.

Features that take configurable parameters surface in the wizard between template selection and the compliance step. Self-contained features (historical-balances, voting-power, conversion-minter, permit) attach without operator input.

## After deployment [#after-deployment]

Most feature parameters are restricted-mutable. Updates run through the governance-update path rather than free edit. The asset detail workspace exposes a per-feature tab where the operator inspects and operates the live feature.
