Exchange

The Universal Exchange lets you trade resources and ships with other players across the universe. It uses a shared exchange rate and delivers purchases through the exchange delivery queue.

How the Exchange Works

The Exchange Location

The Exchange is a global hub at 0:0:8. All Exchange transfers fly to this coordinate first, then deliveries are handed to you through My Deliveries.

Exchange Rates

At the top of the Exchange screen you will see the current Metal (M), Crystal (C), Deuterium (D), and Fuel Cell (F) ratios. These ratios drive:

Estimated costs for Buy Now orders
How much you receive when listings are matched

Rates are calculated from the total resources in the universe and how far each resource is from the desired target share.

Fuel Cells are treated as 100x rarer than the baseline 3:2:1:1 share. Practically, this means:

Fuel Cell target share = (1/7) / 100 = 1/700
The remaining 699/700 share is split across Metal/Crystal/Deuterium using 3:2:1
Total universe resources = metal + crystal + deuterium + fuel cells.
Ratio formula: resource_total / (total_universe * desired_share).

Rates can shift as the exchange economy updates, so always check before sending a trade. Rates are recalculated from an hourly economy snapshot, with values interpolated in 5-minute steps between snapshots. This means the displayed ratios can move every 5 minutes, but are based on the latest hourly snapshot.

Listings and Transfers

Every listing you create sends a transfer mission to the Exchange:

Resources are sent to the Exchange to open a listing.
Ships are sent to the Exchange to open a listing.
Listings stay Pending until that transfer arrives.

Delivery Queue

Completed trades do not land directly on a planet. They appear in My Deliveries, where you choose when and where to pick them up.

Trading Resources

Offer Resources (Sell Listings)

Use Offer Resources to list a resource for sale.

Steps:

Choose a planet or moon to send from.
Select the resource you are selling and the amount.
Choose the resource you want in return.
Submit the offer.

What happens next:

A transfer mission sends your resources to the exchange.
The listing shows Pending Transfer until the fleet arrives.
Once active, other players can match your offer.
When matched, your payout appears in My Deliveries.

If you have no Small or Large Cargo ships on the selected planet but do have Colony Ships, the Exchange will ask for confirmation before using Colony Ships to deliver the resources.

Recalling an offer:

You can recall Pending Transfer or Active listings.
Recalled resources return to My Deliveries.

Buy Resources (Buy Now)

Use Buy Now to purchase resources immediately.

Steps:

Choose the resource you want and the amount.
Choose the resource you will pay with.
Select the planet or moon to send from.
Confirm the estimate and submit.

What happens next:

A transport mission carries payment to the exchange.
Until that payment arrives, the order is treated like a listing in transit.
The exchange fills available listings on arrival.
Any remaining amount becomes a sell listing at the current exchange rate.
Your purchased resources appear in My Deliveries.

Partial Fills and Over-Buys

If there are not enough listings to fully satisfy your buy order:

The Exchange fills as much as it can immediately.
The remaining amount becomes a new sell listing at the current ratio, so it stays visible on the market.

Resource Offer Statuses

Pending Transfer: Your transfer is still flying to the Exchange.
Active: The listing is live and can be matched.
Filled: Fully matched.
Canceled / Recalled: Returned to your deliveries.

Trading Ships

Sell Ships

Sell ships you already own by listing them on the exchange.

Steps:

Pick the planet or moon holding the ships.
Select ship type and quantity.
Set a price per ship and the resource you want.
Submit the listing.

What happens next:

Ships are transferred to the exchange.
The listing stays Pending Transfer until ships arrive.
You can update price and resource while the listing is active.
You can cancel listings to retrieve ships back to My Deliveries, but canceling requires paying 5% of the ship build cost in resources from your currently selected planet. If you cannot pay the fee, the listing stays active.

Buy Ships

Buy ships listed by other players.

Rules:

You cannot buy your own listings.
Listings become Pending Transfer while payment is in transit.

Steps:

Choose a listing and quantity.
Pick the planet or moon to pay from.
Confirm the purchase.

What happens next:

A transport mission delivers payment to the exchange.
When it arrives, ships are added to My Deliveries.
The seller receives the payout in My Deliveries.
If the payment fleet is recalled, the listing becomes available again.

Tips & Best Practices

Check your cargo capacity before large orders.
Watch the ratios; they can change between listing and arrival.
Use Pending Transfer status to estimate when listings will go live.
Keep an eye on My Deliveries to avoid leaving payouts unclaimed.
