# SD Bonding Curve

### What is the SD Bonding Curve?

The SD Bonding Curve is a SmartDeFi™ launch model with dynamic pricing. Price rises as more tokens are bought.

All trading stays inside the bonding contract while the curve is active. Regular swap trading starts after liquidity is created.

### How the model works

{% stepper %}
{% step %}

#### Create the token

Create the token from the SmartDeFi™ Launchpad under **Bonding Curve**. Use the default **1B** supply.

Keep **100%** of the supply in the owner wallet until deployment. Do not transfer tokens before launch.
{% endstep %}

{% step %}

#### Deploy the curve

The owner deploys the bonding curve from the project dashboard. The full supply moves into the bonding contract at launch.

You can also set:

* An initial owner buy of up to **10%**
* An anti-whale limit
* An optional vesting period
  {% endstep %}

{% step %}

#### Trade during bonding

Participants buy and sell directly through the bonding contract. Earlier buyers get a lower price.

If vesting is enabled, earlier entries lock longer:

* **3×** base vesting below **33%** completion
* **2×** base vesting from **33%** to **66%**
* **1×** base vesting above **66%**
  {% endstep %}

{% step %}

#### Finalize and open swap trading

The curve auto-finalizes at **24 BNB** on mainnet. It can also be finalized manually after it passes **6 BNB**.

At finalization:

* Liquidity is created
* Liquidity tokens are burned
* Unsold tokens are burned
* Regular swap trading becomes available
  {% endstep %}

{% step %}

#### Claim purchased tokens

Purchased tokens stay in the bonding contract until finalization. Users claim them after liquidity is live.

If vesting is active, claims unlock only after the vesting period ends.
{% endstep %}
{% endstepper %}

### Key rules

* Use the SmartDeFi™ deployer only
* Do not use a custom token contract
* Do not add liquidity manually
* Do not launch an LGE presale for the same token

### What happens after completion

Once the curve finishes, the token works like a normal SmartDeFi™ token. It can be traded, transferred, and staked, subject to any active vesting rules.
