Phantom is a high performance proxy for accessing distributed services. It is an RPC system with support for different transports and protocols. Phantom is inspired by Twitter Finagle clients and builds on the capabilities of technologies like Netty, Unix Domain Sockets, Netflix Hystrix and Spring. Phantom proxies have been used to serve several hundred million API calls in production deployments at Flipkart.

Phantom is the "ghost who walks" - an entity whose presence can be felt (in a good way) but its existence need not be acknowledged. The Service Proxies fit this analogy well and therefore earned the moniker "Phantom". Motivation for creating Phantom and design overview is described in this Proxies for resilience and fault tolerance in SOA blog post.
The Getting Started page has "5 minute" examples to help you start using Phantom proxies.
Phantom project modules that start with "sample" - for e.g. sample-http-proxy, sample-task-proxy are example proxy implementations. Documentation is continuously being added to the Wiki page of Phantom (https://github.com/Flipkart/phantom/wiki)
