To support our Zero Hash Settlement Service offering, a navigation link enabling participants to make account transfers is now visible in SeedPortal. This link is entitled 'Transfers'. It is used to re-allocate funds from the standard Seed trading account into one or more accounts that specifically support Zero Hash Settlement trades.
Note: This link is currently visible to all participants; it may be hidden in the future to ensure a smooth user experience for participants who do not employ our Zero Hash Settlement Service offering.
