# I. POL Mechanism Overview: Self-Operated Liquidity Logic

When users purchase bonds, the system automatically implements the following strategy breakdown:

#### Entry Breakdown (50% / 50%)

* 50% → Stable assets (such as USDT)
* 50% → Purchase ARK from the market, forming ARK/USDT LP

#### LP Automatic Lockup (Protocol-Owned)

* LP will be locked through protocols like PinkLock
* After maturity:
  * ARK is burned (Burn)
  * USDT enters Treasury, becoming RFV (Risk-Free Value reserve)

#### Synchronized DAO Pool Token Lock

* Users receive ARK (including discount) → Automatically staked as sARK
* Protocol synchronously injects an equivalent amount of ARK for DAO governance, distribution, and incentives
