#### **1. Hero Card Purchase and Pricing Rules**
Hero cards can be purchased using **ACP or USDT**, with **ACP prices fixed** and **USDT prices dynamically adjusted** as follows:
* **Classic Hero Card**: 200 ACP
* **Golden Hero Card**: 1500 ACP
* **Classic Hero Card to Golden Hero Card Price Ratio = 1:7.5**
**1.1 USDT Price Calculation**
As ACP prices fluctuate with the market, the USDT price for purchasing Hero Cards will be based on the **real-time ACP market price**, updated **every minute**.

#### **2. Hero Card Usage and Recharge Rules**
**2.1 Basic Hero Card Usage**
* Each Hero Card is **usable for 30 days by default**, but only **the used hero cards** will unlock **one day of use** per day and release **5 action points**.
* **Players can recharge Hero Cards at any time** to extend their usage period.
**2.2 Recharge Rules**
* **Standard Recharge Price** = 30-day standard price (i.e., 200 ACP / 1500 ACP)
* **Discount for days exceeding 30** is calculated as follows:
$$
Recharge Price=30DayStandardPrice×(1+n/30×70%)\text{Recharge Price} = 30\text{day standard price} \times \left( 1 + \frac{n}{30} \times 70% \right)
$$
Where **n** is the **number of days exceeding 30**. The more days players recharge, the higher the discount.
💡 **Example for Classic Hero Card**:
* Recharge for **30 days**, the price is **200 ACP**
* Recharge for **60 days**, the price is **200 × (1 + 30/30 × 70%) = 340 ACP**
* Recharge for **90 days**, the price is **200 × (1 + 60/30 × 70%) = 480 ACP**
⚠️ **The following rules are based on Classic Hero Card. For Golden Hero Card, all rewards should be multiplied by 7.5 times.**

3. **ACP Earning Mechanism**
Hero card holders can earn ACP rewards through daily activities as follows:
**3.1 Basic ACP Earnings**⚠️ The rewards will directly claimed to the user's wallet by using the hero card to fight.**Classic Hero Card**: **1.7 ACP** per day, with **0.34 ACP** per action point (1.7 ÷ 5 points).**Golden Hero Card:** **1.7 × 7.5 = 12.75 ACP** per day, with **2.55 ACP** per action point (12.75 ÷ 5 points).
**3.2 Continuous Check-in Bonus**After using the hero card every day, a countdown will start with the usage time. After the countdown ends, you can continue to Check-in the next day
* Each day of continuous Check-in by using the hero card increases the reward
* The rewards will claimed to the player's Savings pool
* The Check-In Reward follows a **7-day cycle.**
* Players must **check in continuously for 7 days** to accumulate increasing rewards.
* **Missing a day, the cycle resets**.
* After completing a 7-day cycle, the check-in will start again, players can **pause and resume anytime**.
This system allows players to **rest between cycles**, and does not require **continuous Hero Card production.**
**⚠️ Note**:If the player **does not consume all daily action points**, the ACP that should have been earned will be stored in the **total prize pool** such as:
* 3 Points are not used, then the 1.7 ÷ 5 × 3 = 1.02 ACP will be added to the total prize pool.
\
**Classic Hero Card Continuous Check-in Rewards**:
| Day | Daily Sign-in Reward (ACP) | Golden Hero Card (ACP) |
| --- | -------------------------- | ---------------------- |
| 1 | 1.428 | 10.71 |
| 2 | 1.706 | 12.80 |
| 3 | 2.039 | 15.29 |
| 4 | 2.437 | 18.28 |
| 5 | 2.912 | 21.84 |
| 6 | 3.48 | 26.10 |
| 7 | 4.159 | 31.19 |

**3.3 Savings Pool Rewards**
**3.3.1** **Reservoir Rewards:** When players complete the game with the hero card, in addition to the direct reward, there is a bonus pool that provides the same ACP, which is stored in the personal savings pool.
* **Classic Hero Card**: **1.7 ACP** per day, distributed from the reservoir, with **0.34 ACP** per action point
* **Golden Hero Card** = **1.7 × 7.5 = 12.75 ACP** per day, distributed from the reservoir, with **2.55 ACP** per action point
\
**3.3.2** **Savings Pool Accumulation:** Aside from **basic ACP production**, the **Savings Pool generates an average daily interest of 2% recently**, which translates to an **annualized return of 720%**. However, since the **returns depend on the ecosystem’s overall growth**, it is a **floating** rather than a **fixed return**. The saving pool is a lifelong commitment to core players.
* The **ACP accumulated in the Savings Pool** can be claimed **anytime**.
* Even if players **stop buying Hero Cards**, **past contributions will continue earning interest**.
Example Calculation by Classic Hero Card in one year:
* **30 days of principal in the savings pool:** 1.7× 30 + 75.778 (30 days Check-in Bonus) = 126.78 ACP
* **One year interest:** 126.778 ACP (30-day principal) × 720% (annualized return) **= 912.8 ACP**
* **Direct output per month: 51 ACP (Direct claimed) + 126.778 ACP (Savings Pool principal for permanent interest) + return from saving pool (Forever).**
* This amount **keeps growing** as long as you remain in the ecosystem.
* The **Savings Pool allows withdrawals** but does **not allow new deposits**.
* **If you withdraw from the Savings Pool, you forfeit future passive earnings.**
\
✅ **ACP Trading Value Growth:**
* Before TGE, we **partnered only with long-term investors** who believe in **AOF’s sustained growth**.
* This prevents **large-scale dumping** from early holders and ensures **ACP remains deflationary**.
* With **ecosystem growth**, ACP’s value is expected to **increase steadily**.
\
**3.3.3** **Savings Pool Mechanism Introduction:**
* When players **take a break**, their **past contributions still generate long-term benefits**.
* Instead of forcing **continuous purchases**, your previously earned ACP will **continue earning interest over time**.
* Whether you remain **active** or **step back**, the **Savings Pool ensures ongoing rewards** from the ecosystem’s success.
⚠ **Important:** The **ACP ecosystem’s stability and continued development** will determine the longevity of this system. As long as the project thrives, **your past contributions will continue generating benefits**.
4. **Daily Interest Pool Distribution Rules**
To ensure the healthy operation of the game economy, all unspent rewards, additional subsidies, and part of the event prize pool will flow into the **interest pool (total prize pool)**, and daily interest will be distributed based on players' savings.
**4.1 Sources of Fund Flow into the Total Prize Pool**
**4.1.1 Sign-in Interrupt Subsidy Pool**
* If a player interrupts their continuous sign-in, the ACP that should have been earned will enter the **total prize pool** to balance the economy. Active players will earn more ACP, making profits higher!
**4.1.2 Winning Streak Contract Subsidy Pool**
* In the winning streak contract system, **the previous day's profit** will directly enter the **total prize pool** to reward more active players and support future earnings distribution.
**4.1.3 Wasted Action Points Subsidy Pool**
* The ACP earned from any unused action points (energy points) will be added to the **total prize pool,** ensuring fairness in the economy. Unused rewards will be shared by more diligent players. Are you willing to let the opportunity slip away?
**4.1.4 Event and Competition Subsidy**
* **First-kill competitions, event prize pool subsidies**, and other in-game competitive activities will contribute part of the rewards to the **total prize pool**, strengthening the reward circulation system and supporting long-term operations.
**4.1.5 Revenue from New Games**
* Profits from **AOD (Arena of Destiny)**, our second **ACP-powered game**, will be used to burn ACP and **replenish the Savings Pool**.
**4.1.6** **ACP Advertisements**
* Advertising revenue **within the ACP ecosystem** is used for **ACP burns** and **Savings Pool subsidies**.
**4.1.7 Burn Mechanisms**
* **3% of ACP burned** from the previous day is redirected into the **Savings Pool**. *(Transactions such as **Hero Card minting, skin synthesis, and other in-game actions** contribute to ACP burns.)*
**4.1.8** **Competition Revenue** – **5% of competition handling fees** will be allocated to the **Savings Pool**. As the **ecosystem grows**, the **Savings Pool will become more robust**.
**4.1.9 Single-token Staking Subsidy Pool**
* The ACP in the savings pool can earn stable interest every day, and can also increase its income through single-token staking, which is equivalent to a high-interest deposit in a bank.

### **Hero Card Bounty Hall**
This feature is designed to help users efficiently utilize their assets and provide an additional way for regular users to earn ACP. The above continuous check-in and savings pool rewards are calculated based on the action points of the hero card, and the same applies to bounty hunters.
**ISSUER**:
* Can list any number of unused hero cards (cards that have not used energy points that day).
* Can set requirements for hunters, such as hunter level, ranking, etc.
* The maximum bounty days cannot exceed the minimum remaining days of the listed hero cards.
* Ongoing orders can be monitored for daily progress, and the lister can terminate the order early.
**HUNTER**:
* Must meet the basic requirements of the listed order.
* Must stake 10% of the total ACP output of the order.
* In cases of passive bounty (e.g., unused converted energy points reset), any losses for the lister will be deducted from the deposit. If the deposit is exhausted, the order will be terminated early.
