Observing State

Read values from logic or actor storage:

observe <logic>.<Logic|actor>.field

Examples

# Logic state
observe Flipper.Logic.value

# Actor state (using Sender, username, or identifier)
observe ContextFlipper.Sender.value
observe ContextFlipper.default_user.value
observe ContextFlipper.0x3354...1a13.value

# Map values (access by key)
observe MapLogic.Logic.mapValue["key"]

Atomic Storage

MOI uses atomic storage — you can only access individual map keys, not complete maps. This reduces data transfer from the blockchain.

observe MapLogic.Logic.mapValue      # Returns key count only
observe MapLogic.Logic.mapValue["x"] # Returns actual value

Storage Keys

For advanced use, generate storage keys directly:

storagekey <slot> idx(<u64>) fld(<u8>) key(<0xMapKey>)

>>> storagekey 0 idx(7898) fld(99) key(0x79d5...6f5d)
0xe5cc...5327

>>> observe MyLogic.Logic.0xe5cc...5327
