#### **The energy purchase transaction involves several actions, including adding liquidity to the STM-ETH liquidity pool, paying out administrative rewards, and accruing referral rewards.**&#x20;

**This transaction covers the following sequence of events:**

* Payouts of referral program rewards at each level in crystals,
* The amount of ETH designated for the liquidity pool, along with an equivalent amount of minted STM tokens, is sent to the BaseSwap contract,
* LP tokens are sent to the game's main smart contract for locking,
* A partner commission is charged and sent to a separate marketing address.
