The IPC team is working on delivering IPC features incrementally based on the roadmap planning in milestones. We expect to deliver a market-ready GA version by Milestone 3. The rough roadmap of IPC is:

✅ Milestone 1: The testnet-ready version to deploy a Lotus-based IPC subnet.

✅ Milestone2.5: IPC preview.

• This milestone migrates away from the Eudico/Lotus stack to the Fendermint stack.
• Developers can spin up new IPC subnets anchored on Filecoin's Calibration network for general purposes with the fast block time and finality, not customization at this stage.

[WIP] Milestone 3: Production-grade manually-created, customizable L2+ networks

• Audited and tested a version of the Fendermint stack that is safe to deploy production apps and move customers’ funds into (well-designed) subnets.

Milestone 4: Support for user-deployed Wasm actors + multi-subnet apps + QoL improvements.

• Developments from the FVM team make it safe to support user-deployed Wasm actors and runtimes.

• Streamlines the operation of multi-subnet/federated apps by introducing multi-hop networks and subnet-aware wallets.

• Network-wide and subnet explorers, plus better infra recipes are introduced at this stage.
