ColdStack is a Decentralized Cloud Aggregator that allows for the aggregation of Decentralized Cloud Storage Platforms or Decentralized Storage Networks (DSNs) such as Filecoin, SIA, Arweave, and Storj. It simplifies the use of these platforms without requiring extensive integration efforts, regardless of an individual's familiarity with DSNs. With ColdStack, you can access almost any DSN through the S3 protocol, making migration to ColdStack a seamless process.

As the first-to-market Decentralized Cloud Aggregator, ColdStack serves as a single-entry point to any DSN, optimizing costs for consumers through our proprietary AI-based pipeline. Similar to how Uber connects clients with convenient and cost-effective rides and deliveries from a large pool of drivers, or how 1inch sources liquidity from various exchange pools, ColdStack provides users with the most convenient way to access the world's most affordable, secure, and efficient storage space from any decentralized cloud.

ColdStack's AI selects the best storage option for your data available on the market, enabling users to save up to 80% on storage costs. Different files and data have unique characteristics, such as file size, type, and duration of storage, which can significantly impact overall storage costs. Our AI continuously scans the decentralized storage marketplace to ensure that data is stored in the most efficient manner.

Instead of users manually migrating their data between platforms to obtain the best price and highest efficiency, our AI can automatically rebalance a user's files. ColdStack's protocol also reduces storage costs through techniques such as utilizing cold storage for files that don't require frequent access, bulk purchasing of storage space on various DSNs, and participating in storage auctions.

Our protocol's primary purpose is to store and retrieve user data in a stack of Clouds via Unified Data Exchange API, which is fully compatible with Amazon S3 API. This allows any project to utilize any AWS library or SDK and seamlessly integrate with our system. We will also publish an open-source library with an AWS S3 compatible API for most Decentralized Storages. For more information about our API and its implementation, please refer to our documentation.
