Bonding Curve

Bonding curves create predictable, automated pricing mechanisms without relying on order books. As more tokens are purchased, the price increases, and when tokens are sold or burned, the price decreases. The curve shape depends on the chosen pricing function (linear, exponential, logarithmic).

🔄 How Bonding Curves Work

1. Users buy tokens → The bonding curve algorithm mints new tokens and increases their price.
2. Users sell tokens → Tokens are burned or removed, lowering the price.
3. Liquidity pools or treasuries store the underlying collateral for buybacks and sales.

⚙️ Types of Bonding Curves

✅ Linear Curve – Price increases at a constant rate (e.g., y = x). ✅ Exponential Curve – Price increases exponentially as supply grows (e.g., y = x²). ✅ Logarithmic Curve – Price increases rapidly at first, then levels off (e.g., y = log(x)).

🔥 Benefits of Bonding Curves

• Automated, transparent pricing – No need for centralized price-setting.
• Instant liquidity – No need to wait for buyers/sellers; users can trade anytime.
• Fair token distribution – Ensures early buyers enter at lower prices, rewarding early adopters.

🏛 Example 1: AMMs (Uniswap’s x*y=k Formula)

Uniswap uses a bonding curve model where x * y = k, meaning as one asset is bought, the other increases in price, balancing liquidity pools dynamically.

🏛 Example 2: NFT Projects & Token Sales (Zora)

Zora, an NFT platform, sells NFTs using bonding curves, where early buyers pay less, and later buyers pay more as demand increases.

⚠️ Controversies & Misconceptions

• “Bonding curves always guarantee profits” – False. Prices depend on demand, and sudden sales can lead to rapid price drops.
• “All bonding curves are the same” – Different projects use customized pricing functions tailored to their goals.

🚀 Conclusion Bonding curves create dynamic, algorithm-driven pricing models, widely used in DeFi, NFTs, and token launches. While they provide fair pricing and liquidity, users must be aware of volatility risks and curve mechanics before participating.
