💁‍♂️Decentralized Mint Presale Creation Guide

Create 100% Trustless Presale Contracts in Minutes

Simple Presale Feature Explanation

What is a Simple Mint Presale?

A fully on-chain fundraising method where users send BNB/ETH to a smart contract, automatically receiving tokens at preset rates.

Key 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)

Critical Precautions

⚠️ Pre-Launch Checklist:

1. Enable Manual Trading Activation to prevent premature liquidity

2. Never blacklist presale contract address

3. Verify token contract whitelisting

5. How Does Presale Start and End?

1. 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.

1. 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

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

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)

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
Minimum	≥ Price/Slot (e.g., 0.001 BNB/ETH)
