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](https://github.com/curvefi/curve-contract/blob/master/contracts/tokens/CurveTokenV1.vy): LP token targetting Vyper [^0.1.0-beta.16](https://vyper.readthedocs.io/en/stable/release-notes.html#v0-1-0-beta-16)
-   [CurveTokenV2](https://github.com/curvefi/curve-contract/blob/master/contracts/tokens/CurveTokenV2.vy): LP token targetting Vyper [^0.2.0](https://vyper.readthedocs.io/en/stable/release-notes.html#v0-2-1)
-   [CurveTokenV3](https://github.com/curvefi/curve-contract/blob/master/contracts/tokens/CurveTokenV3.vy): LP token targetting Vyper [^0.2.0](https://vyper.readthedocs.io/en/stable/release-notes.html#v0-2-1)

todo: add hyperlink to deployment addresses

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.
