+The AEA framework provides the developer with multiple features which combined can not be found anywhere else in the space:
+
+* The **Peer-to-Peer Agent Communication Network (ACN)** allows your AEAs to interact with all other AEAs over the public internet.
+
+* The **Search and Discovery system (sOEF)** allows your AEAs to find other AEAs.
+
+* The **AEA Registry** enables code sharing and reuse by providing a space in which AEAs or their individual components may be shared.
+
+* The Framework's **crypto and ledger APIs** make it possible for AEAs to interact with blockchains. 
+
+* The **contract packages** enable AEAs to interact with smart contracts in Fetch.ai and other third-party decentralized ledgers.
