# CommandSubmissionServiceGrpc

> Allows clients to attempt advancing the ledger's state by submitting commands. The final states of their submissions are disclosed by the Command Completion Service. The on-ledger effects of their submissions are disclosed by the Update Service. Commands may fail in 2 distinct manners: 1. Failure communicated synchronously in the gRPC error of the submission. 2. Failure communicated asynchronously in a Completion, see ``completion.proto``. Note that not only successfully submitted commands MAY produce a completion event. For example, the participant MAY choose to produce a completion event for a rejection of a duplicate command. Clients that do not receive a successful completion about their submission MUST NOT assume that it was successful. Clients SHOULD subscribe to the CompletionStream before starting to submit commands to prevent race conditions.
