 # Fadroma Agent: Scriptable User Agents for the Blockchain
 
-The **Fadroma Agent API** is Fadroma's imperative API for interacting with smart contract
-platforms. It's specified by the [**@fadroma/agent**](https://www.npmjs.com/package/@fadroma/agent)
-package, and is in effect a reduced and simplified vocabulary that covers the common ground
-between different implementations of smart contract-enabled chains. The Agent API is designed
-to expressing smart contract operations in a concise and readable manner.
