The code for the implementation of the IPC subnet actor has been moved to https://github.com/consensus-shipyard/ipc-actors. Refer to the maintained code there.
Reference implementation of the InterPlanetary Consensus (IPC) subnet actor. This implementation targets the Filecoin FVM. Subnet actors are responsible for implementing the logic that governs the operation of subnets.
Subnet actors are deployed in the parent network from which the subnet wants to be spawned, and it interacts with the Subnet Coordinator Actor for its operation. In order to deploy your own subnet you can either deploy this reference implementation, or implement your own actor with your own custom policies to fit the needs of your subnet and applications.
Disclaimer: The subnet actor is a user-defined actor that target the Filecoin FVM. IPC is being ported to target FVM, if you are looking to use IPC in its full potential in the meantime have a look at the current MVP here_
