# Off-Chain Currencies

<figure><img src="/files/sm0KKlp8wY5KMpdDhLH3" alt=""><figcaption></figcaption></figure>

**OKA** and **TOKE** are non-tradable, off-chain sub-currencies. They are used to determine the amount of $AURY we distribute to players based on how much effort they put into games and their performance.

OKA is the sub-currency used to reward players for ranked PvP wins in Amiko Legends as long as their Prime Amikos have OKAnergy points.

TOKE is used as a sub-currency to reward players for ranked PvP wins in Amiko Legends with Amikos that have run out of OKAnergy points or Standard Amikos.

Every week, we split the $AURY into two pools: OKA and TOKE. Here's the breakdown: 90% of the total goes into the OKA pool and 10% goes into TOKE. **The ratio is subject to change**, as are the opportunities to earn OKA/TOKE.

**Crystals**

The goal of crystals is to allow all players to progress and buy items without the need to have $AURY or USD. They will be used throughout our ecosystem for purchases, mostly concerning Standard (off-chain) assets, and can be used to hatch eggs, amplify Amikos, purchase items from merchants (when available), participate in tournaments, access certain fee-based game modes, and buy cosmetics in the shop. Crystals are an off-chain currency and do not hold any value outside of the game they're in. You can earn crystals by exploring lands, battling wild Amikos, completing quests (when available), and participating in events.
