Bonding Curves
Web3 / defi
Bonding curves are mathematical functions that establish a direct relationship between a token's price and its circulating supply, creating automated market making without requiring external liquidity providers. As more tokens are purchased from the curve, the price increases; as tokens are sold back to the curve, the price decreases. The specific curve formula determines how aggressively prices rise with supply growth, with exponential curves creating steep price increases and linear curves creating gradual increases. Tokens backed by bonding curves derive their value from the increasing cost to purchase additional tokens rather than from traditional order book markets or liquidity pools. Example: Bancor pioneered bonding curves for token launches, allowing projects to raise capital while providing automated market making, with the curve price adjusting algorithmically based on buy and sell pressure. Why it matters for DeFi: Bonding curves enable decentralized token pricing and fundraising mechanisms that reduce dependency on centralized exchanges. They create continuous liquidity for smaller tokens while generating predictable price discovery, though they require careful parameterization to avoid rug pulls or unsustainable growth.
