Walrus
What it is
Walrus is a verifiable 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; stored data expires when its paid duration ends. Walrus Memory gives AI agents persistent, portable memory across apps and sessions, with semantic remember and recall, automatic fact extraction, and answers grounded in stored memories. It lists native MCP support, OpenClaw and NemoClaw plugins, major-LLM compatibility, and TypeScript and Python SDKs. Memories are encrypted before storage and decrypted only after an authorized signed request. Sui smart contracts enforce ownership and programmable access, including scoped delegation. The Walrus Console is separately in a closed, invite-only Mainnet beta. Each Console space allows up to 5 GB and five folders, with uploads capped at 100 MiB. Walrus Memory has a launch-period plan at no cost, with usage limits that may change.
For and against
For
- Decentralized storage coordinated through Sui
- Provides persistent memory for AI agents
- Supports MCP and listed agent plugins
- Encrypts memories before storage
- Offers TypeScript and Python SDKs
Against
- Stored data expires after paid duration
- Console is invite-only Mainnet beta
- Console uploads are capped at 100 MiB
- Memory usage limits may change
The verdict
Walrus combines verifiable decentralized storage with agent-oriented memory tools and encrypted access controls. Its expiry model, beta Console restrictions, and evolving free-plan limits matter when planning use.
Who it suits
It suits developers and AI-agent builders needing decentralized storage, portable memory, or programmable access controls. Console users must have an invitation to the Mainnet beta.
