delete
Removes a stored keyshare. After this call completes the supplied keyId is no longer resolvable through the SDK's operations.
Implementation detail: the SDK writes a ReconcileStoreDao with both currentKeyshare and stagedKeyshare set to null into the owned StorageClient.
Return
Result.success on successful storage write, Result.failure if the storage operation throws.
Parameters
keyId
Hex-encoded keyId of the keyshare to remove.
