# Donation Presale Creation Guide

## Donation Presale Feature Explanation

### **What is a Donation Presale?**

A fundraising model where a percentage of presale proceeds (BNB/ETH/tokens) is automatically donated to influencer wallets (e.g., Vitalik’s Wallet) to generate marketing buzz.

### Mint Features:

* 🔒 **No Frontend Needed**: Pure contract operations
* 💸 **Transfer-to-Participate**: Users send Native Token(BNB/ETH) → Auto-receive tokens
* ⚙️ **Dynamic Adjustments**: Modify price/supply post-launch via console
* 🚫 **No Caps**: Limited only by total allocation (slots × tokens/slot)

### **Key Features vs Simple Presale**:

* ✅ **Influencer Integration:** Portions of funds flow to high-profile addresses for narrative building.
* ✅**No Manual Marketing:** Auto-donations create organic social traction.

### **Pre-Launch Checklist**

⚠️ **Critical Risks**:

* **Influencer Dumping**: Design safeguards against sudden sell-offs (e.g., vesting schedules).
* **Token Contract**:
  * Whitelist presale contract
  * Disable trading if manual controls exist
* **Avoid ERC20 standard tokens:** Pre-sale users may create liquidity after obtaining tokens, making pre-sale impossible

## **Step-by-Step Creation Tutorial**

### **1. Connect Wallet**

### **5. How Does Presale Start and End?**

1. **Whitelist:**\
   After the presale creation is successful, add the presale contract address to your token contract’s tax whitelist.
2. **Starting the Presale:**\
   In the presale console, click Start **Presale**. You will be prompted for two confirmations:
   * The first prompt is for authorization confirmation.
   * After successful authorization, a second wallet prompt will appear, asking you to transfer sufficient tokens into the presale contract address.
   * Once the tokens are transferred, you will receive a confirmation that the presale has started, and you will see that the tokens are now in the contract.<br>

3. **Ending the Presale:**

* If you wish to end the presale early, simply use the **Claims Tokens** function to withdraw all tokens from the presale contract. This will prevent any further presale transactions.

## FAQ & Troubleshooting

**Q: Donation Ratio Limits?**\
A: 0% (no donation) to 100% (full proceeds to influencer).

**Q: BNB vs Token Donations?**

* **BNB/ETH Donation**: Reduces project treasury funds.
* **Token Donation**: Reduces user rewards.

**Q:Why Presale Launch Fails?**

1. **Insufficient Token Balance**:
   * Required: `Tokens/Slot × Total Slots` (e.g., 10,000 tokens)
   * Actual: Wallet holds < required amount → Presale fails
2. **Whitelist Exclusion**:
   * Presale contract address **not whitelisted** in token contract
3. **Holding Limit Exceeded**:
   * Token contract imposes max wallet holdings < presale allocation

**Q:Why User Purchases Fail Post-Launch?**

| Issue                 | Solution                                                                    |
| --------------------- | --------------------------------------------------------------------------- |
| **Below Min Price**   | Users must send ≥ Price/Slot (e.g., 0.03 BNB) → Excess refunded             |
| **Low Gas Fee**       | Increase gas limit/priority                                                 |
| **Slot Exhaustion**   | Contract has 0 remaining tokens → Adjust Total Slots (if permissions allow) |
| **Incorrect Limits**  | Ensure `Max Slots/Wallet` ≥ `Max Slots/Tx`                                  |
| **Presale Completed** | All slots filled → Modify Total Slots via dashboard (if admin retained)     |

**Q:Can Presale Be Conducted Using wBNB or USDT?**

❌ **Native Tokens Only**:

* BSC: **BNB**
* Base: **ETH**

**Batch Purchase Rules**

* **Full Multiples**:\
  `0.06 BNB (2 slots) → 200 tokens`\
  `0.09 BNB (3 slots) → 300 tokens`
* **Partial Amounts**:\
  `0.04 BNB → 100 tokens + 0.01 BNB refund`\
  `0.07 BNB → 200 tokens + 0.01 BNB refund`

**Presale Limits**

| Type        | Rule                                    |
| ----------- | --------------------------------------- |
