+# What is Agoric Orchestration
+
+Agoric’s Orchestration capability allows developers to easily build cross-chain capabilities into existing applications or to create novel cross-chain-focused products.
+
+The Agoric Orchestration API sits on top of Agoric’s novel VM that provides three key elements that make multichain applications possible:
+- **Remote account control and transfer**: Use the Orchestration APIs to easily create accounts on remote chains, transfer assets, and invoke contracts. Your Agoric contract orchestrates all behavior directly.
+- **Multiblock execution with async & await**: Agoric applications communicate asynchronously and await responses which may come in the same block or many blocks (or weeks!) later. Contracts simply continue executing when the response arrives.
+- **On-chain Timers**: Contracts can set timers for regular execution which makes executing common activities like subscriptions easy.
+
+Agoric’s Orchestration APIs simplify controlling remote chains, moving assets, and using capabilities on any chain the API reaches.

 # Orchestration Overview
 
-Agoric's Orchestration API is a tool to help developers build seamless applications out of disparate interoperable chains and services.
-This composability allows for the development of user-centric applications that leverage the unique strengths of different blockchain ecosystems.

 Orchestration integrates with existing Agoric components ([SwingSet](/guides/platform/#swingset), Cosmos modules) and introduces vat-orchestration. This [vat](/glossary/#vat) manages Inter-Chain Account (ICA) identities and connections to host chains, ensuring proper transaction authorization.
