# Walrus Protocol

**APIs profiled:** 1

Walrus is a decentralized blob storage protocol built on Sui by Mysten Labs, the team behind the Sui blockchain. It provides robust, cost-effective storage for large binary objects with high-availability guarantees using Red Stuff erasure coding across a permissionless set of storage nodes. Data is content-addressed, immutable, verifiable without trusting any single provider, and portable across apps, providers, and AI agents. Developers interact through the `walrus` client CLI, a TypeScript SDK, and an HTTP API served by publisher (write) and aggregator (read) daemons, with storage paid in WAL and on-chain coordination in SUI. Walrus also powers Walrus Sites (decentralized web hosting) and Walrus Memory (a portable memory layer for AI agents). Backed by Electric Capital.
