# what is durianfun

**Durianfun** is a fair-launch meme token platform and AMM trading terminal native to Bitkub Chain (KUB Chain). It combines two proven DeFi primitives into a single, gas-efficient flow:

1. **Bonding curve launchpad** — anyone can launch a meme token with zero presale and no dev allocation.
2. **Post-graduation AMM** — once a token reaches escape velocity, liquidity is automatically sealed into a constant-product pool (x·y=k) with MEV protection.

Every step happens on-chain, atomically, and verifiably. No off-chain scripts, no dev keys pulling liquidity, no hidden mechanics.

## Quick glance

| Property                    | Value                                      |
| --------------------------- | ------------------------------------------ |
| Chain                       | **KUB Chain (id 96)**                      |
| Launch model                | Bonding curve (fair-launch, no presale)    |
| Post-grad model             | Sealed AMM (x·y=k)                         |
| Total supply per token      | 1,000,000,000                              |
| LP allocation at graduation | \~27% of total supply                      |
| Trading fee                 | 1.067% (split between treasury + creator)  |
| Post-graduation AMM fee     | 0.40% (split between treasury + LP growth) |
| Creation cost               | 0.1 KUB (anti-spam "deployment gas cost")  |
| Graduation rewards          | 50 KUB (treasury) + 10 KUB (creator)       |
| MEV protection              | 10-block cooldown after graduation         |

## Who is it for

* **Meme creators** — earn fee share on every trade of your token, forever, even long after graduation's treasury reward is claimed.
* **Traders / degens** — early access to new tokens via the bonding curve. Your entry is always fair because the curve is transparent.
* **Builders** — integrate Durianfun tokens into your bot, terminal, aggregator, or analytics tool using our [public ABIs](file:///4899262/integration/abis.md).

## What makes Durianfun different

{% hint style="success" %}
**First on KUB Chain to combine bonding curve → AMM with creator rebate.** Every trade fees back into the hands of the creator (forever during bonding phase) and the liquidity pool (forever post-graduation).
{% endhint %}

1. **Creator rebate, forever** — 0.167% of every bonding trade flows to the token creator. Whales trade your token for a month? You earn for a month.
2. **Self-compounding LP fees** — post-graduation, 0.10% of every swap stays inside the pool. Depth grows every trade without anyone adding liquidity.
3. **Price-aligned graduation** — when your token matures, the AMM opens at exactly the bonding curve's last price. No surprise dump, no sniper advantage.
4. **MEV-resistant cooldown** — 10-block freeze post-graduation prevents sandwich attacks and priority-bribe sniping.
5. **Immutable fee structure post-grad** — the 0.40% AMM fee is a hardcoded constant. Nobody (not even Durianfun) can raise it later.
