Filecoin Onchain Cloud
Filecoin Onchain Cloud is a programmable storage, retrieval, and payments stack built on Filecoin.
Filecoin Onchain Cloud (FOC) is a programmable storage platform built on the Filecoin Virtual Machine. It combines warm storage, cryptographic storage verification, retrieval, and payments into one developer-facing stack.
Use FOC when you want application-controlled storage on Filecoin without building the storage, payment, provider-selection, and proof flows yourself. The primary integration path is the Synapse SDK; this section points to the maintained FOC quickstart and Synapse docs.
When to use FOC
FOC is a good fit when your application needs:
Programmable storage that can be controlled from a wallet, backend service, agent, or smart-contract-adjacent workflow.
Verifiable persistence through Proof of Data Possession (PDP), so providers regularly prove they still hold the data.
Automated payments through Filecoin Pay, so storage providers are paid through on-chain payment rails.
Retrieval paths for application data, with Filecoin Beam available for faster data delivery.
If you only need a managed IPFS pinning-style workflow, start with Filecoin Pin. If you want to run provider infrastructure for the FOC stack, start with the PDP provider documentation.
Core components
FOC is composed of services that can be used together through the Synapse SDK:
FWSS
Filecoin Warm Storage Service stores data with retrievability-oriented provider selection.
PDP
Proof of Data Possession verifies that providers still hold stored data without requiring a full download.
Filecoin Pay
Payment rails fund storage and settle provider payments based on service delivery.
Filecoin Beam
Retrieval infrastructure for fast data delivery when your application needs it.
Synapse SDK
TypeScript SDK for funding storage, selecting providers, uploading data, downloading data, and managing storage operations.
Developer paths
Synapse SDK
You are building a JavaScript or TypeScript application that stores and retrieves data with FOC.
Filecoin Pin
You want a CLI or API-style path for pinning IPFS-compatible content to Filecoin-backed storage.
