What Is Bonding Curve?
Also known as: Token Bonding Curve, Bonding Curves
In short
A bonding curve is a mathematical formula that ties a token's price to the amount of supply in circulation. As tokens are bought, new tokens are minted and the price rises along the curve; as tokens are sold, they are burned and the price falls.
A bonding curve is managed by a smart contract, and the contract is always ready to trade as both buyer and seller. To buy tokens, users send a reserve asset (for example ETH) to the contract; the contract mints new tokens according to the formula and keeps the reserve. When tokens are sold, payment is made from this reserve. The curve can be linear, exponential or logarithmic; on a linear curve, each new token is a fixed amount more expensive than the one before.
This model provides continuous liquidity without needing an order book or external liquidity providers and makes pricing predictable. Bancor's early versions are among the early applications of this idea. In recent years, memecoin launch platforms such as pump.fun on Solana have popularized a model that sets the initial price of new tokens with a bonding curve and moves the liquidity to a decentralized exchange once a certain market capitalization is reached.
Because early buyers enter at a low point on the curve, they can profit by selling to those who come later; this leaves the structure open to speculation and rapid buy-and-sell behavior. Incorrectly designed curve parameters or smart contract vulnerabilities can also cause losses. A bonding curve does not guarantee that a token has real utility.
