DuplicateContractKey

final case class DuplicateContractKey(key: GlobalKey) extends TransactionError with Product with Serializable

Signals that within the transaction we got to a point where two contracts with the same key were active.

Note that speedy only detects duplicate key collisions if both contracts are used in the transaction in by-key operations meaning lookup, fetch or exercise-by-key or local creates.

Two notable cases that will never produce duplicate key errors is a standalone create or a create and a fetch (but not fetch-by-key) with the same key.

For ledger implementors this means that (for contract key uniqueness) it is sufficient to only look at the inputs and the outputs of the transaction whlie leaving all internal checks within the transaction to the engine.
