Role Reference Parameters in Smart Contracts
It is now (from build 2023-08-10) possible to create smart contracts containing a new type of parameter, the Role Reference Parameter. When creating contracts that need to reference properties of the identities of any of the signatories, you had to previously create duplicate contract parameters to reflect these values. This gave rise to integrity problems, as you had no automatic check that the values were correct. It was also problematic for users, as they had to provide the infomration manually multiple times. With the new type of Role Reference Parameter, the assignment of these parameter values is automatic when the corresponding role signs the contract.
When defining a Role Reference Parameter, you provide:
- The Role
- An Index, where 1 means the first signatory that signs using the corresponding role, 2 means the second, and so on.
- A Property, which references a property in the Legal Identity of the signatory. You can use any well-known ID property, Organization ID property or custom ID property you like.
- If the property is Required or not. If required, a signature from a party lacking this property will not be accepted.
LegalLab
LegalLab has been updated to support Role Reference Paramters. There is also an new example showing how Role Reference Parameters can be used. When loading this example into LegalLab, you will notice that the parameters have been divided into two sections in the Design Tab, the Editable Parameters and the Referenced Signatory Properties:
Before signature, these properties have now values:
Once the contract is signed however (here I’ve signed the contract twice, as illustration), the values automatically become available, and visible in the contract:
ID App
The ID App has also been updated. As soon as the app has been published to App and Play stores, it will be available to users. Meanwhile, develops can access this feature by retrieving the latest version from the repository.
