All tokens are priced relative to $ARKIS (rate = 1). Rates reflect each token's yield value and scarcity. SPORE is rarest and most valuable per unit — PLASM is most abundant.

Every trade incurs a 2% fee on the output token. This fee is distributed to the Luminaea Crown Treasury — supporting the Sovereign and the wider economy of Luminaea.

Each player can make up to 5 trades per day. This prevents arbitrage farming and keeps rates stable. Resets at midnight UTC each day.

Enter an amount on either side. Type how much you want to receive and the widget back-calculates exactly how much to send, including the fee.

Special buildings require specific tokens. A WIRE building can't be paid in PLASM. Exchange lets you convert whatever you've earned into what you need to unlock the build you want.

All exchanges run as a single atomic DB transaction. Rates are fetched server-side — client values are never trusted. Balance is checked before any debit. No partial fills possible.
