## 🔗 Solana Web3 Token Integration ($NI-KA)

NI-KA features native integration on the Solana Mainnet.

* **$NI-KA Token Mint:** `Hp4BLfhrJdqwPKqNpKa5SZg2xLoZQAyZ7v68VMKwVory`
* **Deterministic Deposit Wallets:** Every registered user is assigned a unique, secure public address derived server-side.

### Token Burn Engine (Premium Multiplier)

Bridge $NI-KA tokens directly into in-game Galaxy Coins through a secure, server-authoritative burn:

* **The Conversion Formula:**

  $$
  \text{Galaxy Coins} = \text{Token Amount} \times \frac{\text{Token Price}}{\text{SOL Price}} \times \text{BASE\_G\_RATE} \times \text{TOKEN\_G\_MULTIPLIER}
  $$
* **Parameters:**
  * **BASE\_G\_RATE:** 20,000 Galaxy Coins per SOL.
  * **TOKEN\_G\_MULTIPLIER (1.5x Bonus):** Converting native $NI-KA tokens grants a **50% bonus** in Galaxy Coins compared to direct SOL donations, rewarding ecosystem participants.
  * **Minimum Burn:** Value must equal at least `0.01 SOL` equivalent.

## 📺 Ad-Supported Sponsor Revives

To support players who prefer not to use Web3 mechanics, the game provides an in-game advertising model:

* **Sponsor Ads:** Dynamic video and end-card integrations from sponsors (e.g. ODINBOT, more to come).
* **The Reward:** Watch a sponsor ad overlay during a run to revive your ship and recover your lives.
