MemWal (now Walrus Memory)
https://decrypt.co/365834/agentic-memory-walrus-takes-on-ais-next-big-bottleneck
Walrus is a Sui-blockchain decentralised storage protocol; MemWal is its AI-facing SDK that stores encrypted agent memory on-chain — portable, verifiable, shareable across agent systems with no single-vendor lock-in. Targets production agents needing auditability. Renamed Walrus Memory (memwal.ai redirects to memory.walrus.xyz); still in beta, SDK published as @mysten-incubation/memwal.

When to use
Optimised for: verifiability + portability + no vendor lock-in (on-chain)
Anti-fit: not for low-latency / high-write-throughput workloads (chain settlement)
Pros & cons
Pros
Walrus decentralized-storage backed memory — first memory layer with on-chain durability.
Cons
Web3-native — adds crypto / decentralization complexity that most teams don't need.
Claims & capabilities
$140M private token sale ($WAL, 2025) at ~$2B protocol valuation. Plugins for OpenClaw and NemoClaw.

Other dedicated memory layers in the catalog, ranked by inbound references.
- Mem0 T1
Universal memory layer for AI agents. Three concurrent stores (vector + graph + KV); LLM-extracted facts; concurrent retrieval via ThreadPoolExecutor.
- Zep & Graphiti T1
Bi-temporal knowledge graph (event time + ingestion time). Strong on chronological reasoning and contradiction tracking. Graphiti is the open-source core.
- Cognee T1
"Extract–Cognify–Load" pipeline that turns raw input into a typed, queryable knowledge graph for agent recall.
- Hindsight (Vectorize) T1
Standalone memory service from Vectorize. Open source. Biomimetic four-network design (World, Bank, Observation, Opinion). Ships an MCP memory server.
- Letta / MemGPT T1
Originated as MemGPT (UC Berkeley), where the model pages its own memory between context, recall and archival tiers. The product now centres on Letta Code, a stateful agent harness whose agents rewrite their own memory, skills and prompts over time.
- Memori T2
Structured, persistent memory layer for AI agents. Open source.
