Bonding Curve Explained
A bonding curve is a mathematical model that defines the price relationship of a token based on its supply. It determines how the token's price increases as more tokens are bought (minting) and decreases when tokens are sold back (burning). This creates a transparent, algorithmic market maker where:

• Early buyers get lower prices.
• Later buyers pay progressively higher prices.
• Liquidity is programmatically managed.

---

BondCraft’s Bonding Curve

BondCraft uses a linear bonding curve with the formula:
[ P(x) = k \cdot x
]
Where:

• ( P(x) ) = Price per token at supply ( x ) (in USDC)
• ( x ) = Total tokens sold so far
• ( k ) = Curve steepness factor (derived from funding goal)

---

Key Mechanics

1. Curve Parameterization

   • ( k ) is calculated to ensure the total funds raised match the creator’s goal when all "funding tokens" are sold:
     [ k = \frac{2 \cdot \text{FundingGoal}}{\text{(MaxSaleTokens)}^2} ]
     Example: For a $1M goal selling 500M tokens:
     [ k = \frac{2 \cdot 1,000,000}{(500,000,000)^2} = 8 \times 10^{-9} , \text{USDC per token}^2 ]

2. Price Progression

   • Token 1: Price = ( k \cdot 1 = 0.000008 ) USDC
   • Token 500M: Price = ( k \cdot 500,000,000 = 4.0 ) USDC
   • Total raised = Area under the curve = ( \frac{1}{2} \cdot 500M \cdot 4.0 = $1M ).

3. Incentive Structure

   • Early buyers secure tokens at lower prices (e.g., first 10% of tokens cost <1% of total goal).
   • Price predictability encourages strategic participation.

---

Why a Linear Curve?

1. Simplicity

   • Easy to understand and audit.
   • Predictable price movements.

2. Goal Guarantee

   • Mathematically ensures the funding goal is met exactly when all allocated tokens are sold.

3. Fairness

   • No exponential price spikes that could deter late participants.
   • Clear relationship between supply and price.

---

Comparison to Other Curves

Curve Type	Formula	BondCraft’s Choice?	Why/Why Not?
Linear	( P(x) = kx )	✅ Yes	Transparent, goal-guaranteed
Exponential	( P(x) = e^{kx} )	❌ No	Unbounded price growth
Logarithmic	( P(x) = \ln(x) )	❌ No	Too slow for fundraising

---

BondCraft’s Implementation

1. Token Minting:

   • Price updates in real-time as tokens are bought.
   • Smart contract enforces ( x \leq \text{MaxSaleTokens} ).

2. Post-Funding:

   • Curve halts after ( x = \text{MaxSaleTokens} ).
   • Remaining tokens (creator/liquidity/fees) are distributed.

3. Move Code Snippet:

   public fun calculate_price(tokens_sold: u64, k: u64): u64 {
       // Linear price calculation
       (tokens_sold as u128 * k as u128 / 1_000_000_000) as u64
   }

---

Why This Works for Sui

• Parallel Execution: Multiple independent launchpads operate simultaneously.
• Move Safety: No overflows or reentrancy bugs.
• Sui AMM Integration: Seamless liquidity pooling post-funding.

BondCraft’s linear bonding curve strikes the perfect balance between mathematical rigor and practical usability, making it ideal for Sui’s high-throughput DeFi ecosystem.

Project Name: BondCraft Launchpad
Tagline: "Parameterized Fundraising on Sui’s Bonding Curve Engine"

---

Project Description

BondCraft is a next-generation token launchpad designed exclusively for the Sui blockchain, enabling creators to launch customizable, mathematically governed fundraising campaigns. Unlike traditional launchpads, BondCraft integrates dynamic bonding curves with fully parameterized tokenomics, allowing projects to define their own supply distribution, funding goals, and incentive structures while ensuring early contributors are algorithmically rewarded.

Built natively on Sui with Move, BondCraft combines the security of smart contracts with the flexibility of programmable economics, creating a trustless environment for fair token distribution, instant liquidity provisioning, and transparent post-funding governance.

---

Key Differentiation

1. Fully Configurable Launches
   Creators define:

   • Total token supply
   • Funding token allocation
   • Liquidity/Creator/Platform splits
   • Bonding curve steepness (price discovery)

2. Sui-Native Architecture

   • Parallelized launchpad instances via Sui’s object model
   • Integrated with Sui’s AMMs (e.g., Cetus, Turbos)
   • Move-based safety guarantees

3. Algorithmic Fairness

   • Bonding curve rewards early buyers proportionally
   • Auto-vesting for creator tokens
   • Liquidity bootstrapping at funding completion

---

Why This Name Works

• "Bond": Reflects the bonding curve mechanism and financial "bonding" of stakeholders.
• "Craft": Emphasizes the customizable, artisanal nature of launch parameters.
• "Launchpad": Clearly communicates the core purpose (token launches).

3. SuiDynamo Launch (Dynamic + Sui)

2.2 Bonding Curve Mathematics

Price Calculation:

P(x) = (k * x) / 10^6
Where:
- x = tokens sold
- k = curve steepness parameter
- P(x) = price in USDC (6 decimals)

Parameter Derivation:

k = (2 * FundingGoal * 10^6) / (MaxSaleTokens^2)
Guarantees: ∫₀^{MaxSale} P(x)dx = FundingGoal

3. Business Logic

3.1 Token Flow Model

Total Supply (T)
├── Sale Pool (S): X%
├── Creator Allocation (C): Y%
├── Liquidity Pool (L): Z%
└── Platform Fee (F): W%

Constraints:
S + C + L + F = T

3.2 Fee Structure

• Platform Fee: 1-5% of raised funds + fixed token allocation
• Success Fee: 0.5% of liquidity pool tokens
• Curve Parameterization Fee: 0.1% per unique parameter set

3.3 Value Capture Mechanism
