# AutomaticPlaceholderConstraint

`object AutomaticPlaceholderConstraint : AttachmentConstraint`

This AttachmentConstraint is a convenience class that acts as a placeholder and will be automatically resolved by the platform when set on an output state. It is the default constraint of all output states.

The resolution occurs in TransactionBuilder.toWireTransaction and is based on the input states and the attachments. If the Contract was not annotated with NoConstraintPropagation, then the platform will ensure the correct constraint propagation.

### Functions
