* Manage different chains (e.g testnet, private net, livenet)
* Easily manage complex systems of interdependent contracts.
**Decentralized Storage (IPFS)**
**Decentralized Storage (IPFS, Swarm)**
* Easily Store & Retrieve Data on the DApp through EmbarkJS. Including uploading and retrieving files.
* Deploy the full application to IPFS or Swarm.
* Import and deploy contracts hosted on Swarm.
