Overview

In exchange for depositing coins into a Curve pool, liquidity providers receive pool LP (liquidity pool) tokens. A Curve pool LP token is an ERC20 contract specific to the Curve pool. Hence, LP tokens are transferrable. Holders of pool LP tokens may deposit and stake the token into a pool’s liquidity gauge in order to receive CRV token rewards. Alternatively, if the LP token is supported by a metapool, the token may be deposited into the respective metapool in exchange for the metapool’s LP token (see here).

Currently, the following versions of Curve StableSwap LP tokens exist:

CurveTokenV1: LP token targetting Vyper ^0.1.0-beta.16
CurveTokenV2: LP token targetting Vyper ^0.2.0
CurveTokenV3: LP token targetting Vyper ^0.2.0

The version of each pool’s LP token can be found in the Deployment Addresses.

Note

For older Curve pools the token attribute is not always public and a getter has not been explicitly implemented.
