Stellar Ore → Dark Matter

Rate1 Star Ore → 9,000 Dark Matter

Exchange rate

Exchange at the Merchant: 1 Star Ore → 9,000 Dark Matter. Up to 50 Star Ore per transaction.

Base rate from the game code: 1 Stellar Ore yields 9,000 Dark Matter; a payout coefficient of 0.9 is applied (a 10% fee), so effectively 1 Stellar Ore → 8,100 Dark Matter. For example, 50 Stellar Ore turns into 405,000 Dark Matter (the engine rounds the result down). Per transaction you can give at most 50 Stellar Ore. The reverse pair "Dark Matter → Stellar Ore" trades at a base rate of 1 → 0.00011 (payout coefficient 0.25); a round trip returns ≈22.28% of the volume, losing ≈77.72%. The exact in-game rate may differ: the engine adjusts it to demand and trade volumes, while the fee always applies.

The exchange is available at the Trader. The base rate is set in the game code; the actual rate shifts slightly with demand and trade volumes. Dark matter exchange is limited by the amount per operation.
