Zoe Contract Facet

The Zoe interface specific to a contract instance. The Zoe Contract Facet is an API object used by running contract instances to access the Zoe state for that instance. The Zoe Contract Facet is accessed synchronously from within the contract, and usually is referred to in code as zcf.

    Make a credible Zoe invitation for a particular smart contract indicated by the instance in the details of the invitation. Zoe also puts the installation and a unique handle in the details of the invitation. The contract must provide a description for the invitation and should include whatever information is necessary for a potential buyer of the invitation to know what they are getting in the customDetails. customDetails will be placed in the details of the invitation.
