The Smart Storage Unit (SSU) is a crucial Smart Assembly in EVE Frontier, designed to store and dispense items using verifiable, on-chain logic. SSUs serve various purposes, from functioning as trade hubs to streamlining resource management.
Deploying a Smart Storage Unit
To deploy an SSU, players must adhere to specific placement rules and physics:
Network Node: A Network Node must be built at an Anchor Point within the vicinity of the deployment zone.
Distance Requirement: An SSU must be placed at least 200KM away from another SSU to maintain signal integrity and spatial exclusivity.
Strategic Placement: Positioning should be based on purpose; for example, place trade-focused SSUs near stations or mining fields to maximize accessibility.
Item Storage & Inventory Types
The SSU features two distinct inventories governed by the game's Digital Physics:
SSU Inventory
Primary storage directly controlled by the SSU owner.
Access is restricted unless the owner grants specific permissions.
Items stored here belong to the SSU owner and are secure due to the immutable nature of the blockchain. Owners can also utilize privacy protocols (POD) to obscure the contents from public view while retaining proof of ownership.
Ephemeral Inventory
Temporary storage for players interacting with the SSU.
Players can deposit and withdraw items within their personal slot.
Interaction is governed by transfer logic defined in the SSU's Move code.
Inventory Interaction & Transfer Logic
The transfer of items between the SSU Inventory and Ephemeral Inventory is controlled through two key entry points, programmable by the owner:
SSU Inventory Transfer: Allows the transfer of items from the SSU Inventory to a player's Ephemeral Inventory. By default, this is public, but owners can restrict access. Owners can program complex conditions here; for example, releasing items only when a player provides "proof" of completing a quest or a bounty.
Ephemeral Inventory Transfer: Enables players to transfer items from their Ephemeral Inventory to the SSU Inventory. Players control their own transfers, but the SSU owner dictates the overall logic. Owners can approve or disallow direct transfers, requiring specific item types or quantities as payment for services.
A common strategy is to restrict SSU inventory transfers to the owner while allowing smart contract‑controlled interactions for structured transactions, ensuring secure and automated handling of assets.
