Currently, the Marketplaces tab is just a placeholder. In future, you will be able to select a market from the drop-down list and log into it, using your wallet ID and a PIN.
These marketplaces will support trading of other assets and items for which SilentVault voucher assets are accepted as payment. We are currently developing the integrated marketplace feature. If you would like to accept SilentVault assets at your business, please contact us.
