# Bonding Curve Tokens

A bonding curve is a mathematical concept used to describe the relationship between price and the supply of an asset. As supply in the bonding curve increases, the price also has a commensurate increase.

The TEA Project features two types of investment tokens issued on bonding curves:

* A TApp uses bonding curves to issue their [TApp tokens](https://docs.teaproject.org/_3_token/bonding-curve-tokens/tapp-tokens).
* A CML node will also issue separate [CML bonding curve tokens](https://docs.teaproject.org/_3_token/bonding-curve-tokens/cml-mining-tokens).

These are investable tokens that may be purchased from the **Investments** tab in the TEA browser wallet as explained further [here](https://docs.teaproject.org/_3_token/bonding-curve-tokens/tapps-tokens-list).

The bonding curve tokens have a [theta %](https://docs.teaproject.org/_3_token/bonding-curve-tokens/bonding-curve-theta) associated with them as well as [supply & demand values](https://docs.teaproject.org/_3_token/bonding-curve-tokens/tapp-token-supply-and-demand) that are determined by a curve.
