Contract Builder#

Builder is where you define how your contract behaves.

Open: Contracts -> Your Contract -> Builder

Data#

Create your models and fields.

Example model:

• Asset
• fields: id, owner, status

Actions#

Create callable functions.

Function types:

• invoke: write/update state
• query: read state
• verify: validate a business condition

Example actions:

• CreateAsset (invoke)
• GetAsset (query)
• VerifyAssetOwner (verify)

Logic#

Add simple rules to protect state.

Examples:

• Require id and owner
• Allow transfer only for current owner
• Block invalid status transitions

Connections#

Link models for richer reads.

Examples:

• Asset belongs to Batch
• Batch belongs to Shipment

Builder checklist before deploy#

• All required fields are set
• Function inputs are clear
• Rules cover invalid operations
• Function names are final

What just happened#

• You defined data and behavior in one place.
• You created runtime-ready functions through the UI.
• Your contract is ready for deployment.
