Walrus is a distributed data platform for storing and managing information across apps, providers, and agents. Its decentralized storage protocol is coordinated onchain through Sui. Storage costs $0.023/GB/month, paid in WAL, with SUI used for transaction gas; data expires when its paid storage period ends. Walrus Memory gives AI agents persistent memory that can move across apps and sessions. It supports semantic remembering and recall, automatic fact extraction, and AI-generated responses grounded in saved memories. Agent tools include native MCP support, first-party OpenClaw and NemoClaw plugins, and compatibility with major LLMs. Developers can use TypeScript and Python SDKs, a relayer, smart contract, indexer, and dashboard. Sui contracts set ownership and access rules, including scoped delegation. Memories are encrypted before storage and decrypted only after an authorized signed request. The separate Walrus Console is in a closed, invite-only Mainnet beta, with limits of 5 GB and five folders per space and 100 MiB per upload. Walrus Memory has a free launch-period plan, with usage limits and pricing that may evolve.

Who it is for

Walrus may suit developers and AI-agent builders who need portable, encrypted memory or distributed storage. Console access is currently limited to invitees in its closed beta.

What is good

  • Memory supports semantic recall and automatic fact extraction.
  • TypeScript and Python SDKs are available.
  • Access rules allow scoped delegation.
  • Memory is encrypted before storage.

What to know first

  • Storage expires when its paid duration ends.
  • Console beta is closed and invite-only.
  • Console uploads are capped at 100 MiB.
  • Small files carry fixed metadata overhead.

Verdict

Walrus combines distributed storage with a memory service for AI agents, backed by Sui access controls. Note the time-limited storage and the Console beta's access and size limits.
