Understanding Bonding Curves
A bonding curve is a mathematical framework used for issuing digital assets where a token's price dynamically adjusts based on its circulating supply. This automated pricing mechanism operates through smart contracts that:
- Mint new tokens when purchased (increasing supply)
- Burn tokens when sold (decreasing supply)
- Adjust prices according to a predefined supply-price relationship

Historical Context
The concept originated in 2017 when Simon De La Rouvière introduced it in his seminal article "Tokens 2.0: Curved Token Bonding in Curation Markets." Bancor Network later implemented the first practical protocol in 2018.
Mint Club V2's Discrete Bonding Curve Model
Mint Club innovates with its Discrete Bonding Curve (DBC) system featuring:
- Step-Based Pricing: Unlike continuous curves, DBC uses incremental price steps (
BondStep[] { rangeTo, price }) - Price Intervals: Defined ranges where prices remain constant before jumping to the next level
Advantages Over Continuous Models
- Simplified Testing: Eliminates complex power function calculations
- Enhanced Customizability: Enables precise price structuring through array configurations
- Predictable Economics: Clear price boundaries at each supply interval
How Bonding Curve Trading Works
Fundamental Differences from AMMs
| Feature | Traditional AMM (Uniswap) | Bonding Curve System |
|---|---|---|
| Token Supply | Fixed by LPs | Dynamic mint/burn |
| Liquidity Source | Provider-deposited pairs | Automated curve pool |
| Price Mechanism | Pool ratio-based | Algorithmic curve |
Practical Example: CAT Token Economics
Token Specs:
- Max supply: 1,000 CAT
- Base asset: WETH
- Price range: 0.0001 → 0.01 WETH
- 20 price intervals
Buying Process (500 CAT)
- Payment calculation across 10 price intervals (0.441 WETH)
Transaction execution:
- 500 CAT minted to buyer
- WETH deposited to curve pool
- New price: 0.00284 WETH/CAT
Selling Process (250 CAT)
- Value calculation across 5 intervals (0.375 WETH)
Transaction execution:
- 250 CAT burned
- WETH withdrawn from pool
- New price: 0.00079 WETH/CAT

Frequently Asked Questions
How does a bonding curve maintain liquidity?
The curve pool automatically provides liquidity through its algorithmic pricing mechanism, eliminating the need for traditional liquidity providers.
What advantages do discrete curves offer?
Discrete models provide:
- Clear price transparency at each interval
- Easier contract implementation
- More predictable trading costs
Can bonding curve tokens be listed on exchanges?
Yes, though their intrinsic value remains tied to the curve's algorithmic pricing rather than order book depth.
How are creator royalties handled?
Royalties (e.g., 0.3% in our CAT example) are automatically deducted from transactions, with funds going to the token creator.
Conclusion
Mint Club's Discrete Bonding Curve represents a significant evolution in token issuance mechanisms, combining mathematical precision with practical implementation advantages. This model offers projects:
- Automated price discovery
- Continuous liquidity provisioning
- Customizable economic parameters
By understanding these principles, developers and traders can better navigate the evolving landscape of algorithmic token economies.
