Bonding Curve

A bonding curve is a mathematical formula that prices a token based on its circulating supply — the more tokens minted, the higher the price; the more burned/redeemed, the lower. The curve is enforced by a smart contract that acts as a permanent automated market maker against a reserve asset.

✦ Key Insight

Bonding curves power many fair-launch tokens, memecoin launchpads, and continuous token offerings. Traders who understand the curve can model exactly how their buy or sell will move the price before submitting it.

✕ Common Misconceptions

Buying late on a steep curve and expecting the same upside as early buyers.

Ignoring that large sells crash the price along the same curve.

Misreading market cap when supply is still actively expanding.

Detailed Explanation

How It Works: When a buyer sends ETH (or another reserve) to the contract, it mints new tokens at the current price along the curve and stores the ETH in a reserve. Selling burns tokens and returns reserve at the corresponding lower price. Common shapes are linear, exponential, and logarithmic.

FAQs:

Is the price guaranteed? Only against the bonded reserve. After graduation to a regular DEX, normal AMM rules apply.

Can a bonding curve be exploited? Yes — especially through MEV, sandwich attacks, or contract bugs in custom curves.

In Practice

“On a memecoin launchpad, the first $1 buys 1,000 tokens, but the millionth dollar in might only buy 50 — because the curve has steepened. Once enough liquidity is bonded, the token "graduates" to a standard DEX pool.”

Liquidity Pool

A liquidity pool is a collection of crypto assets locked in a smart contract that allows users to trade tokens on decentralized exchanges without relying on a traditional order book.
