Fields

ceNow :: Timestamp
Timestamp returned by the NOW instruction.
ceMaxSteps :: RemainingSteps
Number of steps after which execution unconditionally terminates.
ceBalance :: Mutez
Current amount of mutez of the current contract.
ceContracts :: TcOriginatedContracts
Mapping from existing contracts' addresses to their executable representation.
ceSelf :: Address
Address of the interpreted contract.
ceSource :: Address
The contract that initiated the current transaction.
ceSender :: Address
The contract that initiated the current internal transaction.
ceAmount :: Mutez
Amount of the current transaction.
ceChainId :: ChainId
Identifier of the current chain.
ceOperationHash :: Maybe OperationHash
Hash of the currently executed operation, required for correct contract address computation in CREATE_CONTRACT instruction.
ceGlobalCounter :: GlobalCounter
