Filecoin Onchain Cloud is a marketplace of onchain-verified storage services, settled through Filecoin Pay. Choose warm storage for active data or cold storage for large archives.
Fast, continuously-verified storage for active data. Proven every few minutes with Proof of Data Possession (PDP), from $2.50/TiB/month.
Low-cost, durable archival storage for large, infrequently-accessed datasets. Sealed and proven with Proof of Replication (PoRep), built for 1TiB+ datasets.
Both settle payment automatically through Filecoin Pay — the difference is the proof mechanism and access pattern underneath.

Filecoin Pay is the payment rail underneath the marketplace, not a separate storage product. Smart contracts confirm performance before releasing funds, so you pay only for storage that's actually proven.
