# Farm {% hint style="warning" %} Note that this page has not been updated to reflect the current state of Beanstalk, but is left here as a reference. {% endhint %} The Farm allows Farmers to call multiple functions in a single transaction and use assets between different functions in a composable manner, without those assets every leaving Beanstalk (thanks to [Internal Balances](/developers/overview/internal-balances.md)). Internal Balances allow the `farm` function to use the output of a function in the next function call. The Farm also provides composable Beanstalk-native interfaces for other DeFi protocols. This allows Farmers to call supported external protocols through the `farm` function and leverage Internal Balances. The current protocols that the Farm supports are: * WETH -> wrapping and unwrapping; and * Curve -> swapping and adding/removing liquidity. * Pipeline -> performing an arbitrary series of actions in the EVM in a single transaction. The Farm creates an interface to transfer ERC-20 tokens between Internal and External Balances, as well as between Farmers through the `transferToken` function. The Farm consists of 5 facets: * [Farm Facet](/developers/protocol/depot/farm-facet.md) * [Depot Facet](/developers/protocol/depot/depot-facet.md) * [Token Facet](/developers/protocol/depot/token-facet.md) * [Token Support Facet](/developers/protocol/depot/token-support-facet.md) * [Curve Facet](/developers/protocol/depot/curve-facet.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
