Bonding Curve

What Is a Bonding Curve?

A bonding curve is a smart-contract pricing mechanism that sets a token's price algorithmically based on its supply. The contract mints tokens when people buy and takes them back when people sell, moving the price along a preset mathematical curve — more supply bought, higher price; supply sold back, lower price.

Because the contract itself is the counterparty, a bonding curve provides guaranteed, always-on liquidity from the very first trade — no order book, no market maker, no waiting for a listing. That's why bonding curves became the engine of memecoin launchpads, where thousands of new tokens need instant markets.

How a Bonding Curve Works

1. A contract is deployed with a formula linking token supply to price — often linear or exponential.

2. Buyers send the base asset to the contract, which mints new tokens at the current curve price; the price steps up.

3. Sellers return tokens to the contract for the base asset at the current price, and the price steps down.

4. On many launchpads, a token that reaches a target market size "graduates": the curve's liquidity moves to a regular exchange pool.

What to Watch For

• Early buyers profit from later ones by design — the curve guarantees it, which attracts both fair launches and predatory ones.

• The formula is everything: steep curves mean explosive early gains and brutal drawdowns.

• The contract holds the funds: a malicious or buggy curve contract can trap or drain them.

• Graduation isn't validation — it measures buying pressure, not quality.

Bonding Curves and Trust Wallet

Through Trust Wallet's dApp browser you can reach launchpads and DeFi apps built on bonding curves while your keys stay on your device, and the Security Scanner flags risky contracts before you sign. Understand the curve — and who bought before you — before you buy.
