Resource exchange

Stellar Ore → Antimatter

Rate1 Star Ore → 2.1 Antimatter

Exchange rate

Exchange at the Merchant: 1 Star Ore → 2.1 Antimatter. Up to 50 Star Ore per transaction.

Base rate from the game code: 1 Stellar Ore yields 2.1 Antimatter; a payout coefficient of 0.9 is applied (a 10% fee), so effectively 1 Stellar Ore → 1.89 Antimatter. For example, 50 Stellar Ore turns into 94 Antimatter (the engine rounds the result down). Per transaction you can give at most 50 Stellar Ore. The reverse pair "Antimatter → Stellar Ore" trades at a base rate of 1 → 0.027 (payout coefficient 0.9); a round trip returns ≈4.59% of the volume, losing ≈95.41%. 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.
