Work in Progress

Shadow Drive Persistence

Decentralized Vector Storage

Status: 🚧 In progressCurrent: Vectors stored in-memory only (lost on restart)Goal: Encrypted vectors persisted to Shadow Drive with:

Automatic sync on write
Fast cold-start from Shadow Drive
LRU caching for hot vectors
Cost: ~$0.000039/MB/epoch

ETA: Late March 2026

WASM Rust Bridge

Browser & Serverless Support

Status: 🚧 In progressCurrent: TypeScript SDK uses JavaScript fallback for HNSW queriesGoal: Compile Rust HNSW core to WebAssembly for:

10x faster queries in browser
Serverless Lambda/Cloudflare Workers support
Same performance as native Rust

ETA: April 2026

Agent Memory Demo

Reference Implementation

Status: 🚧 In progressGoal: Production-ready demo showing:

AI agent with persistent memory
Conversation history stored in VecLabs
Semantic recall with .query()
On-chain verification of agent memory
LangChain integration example

Location: demo/agent-memory/ETA: April 2026

Planned Features

Mainnet Deployment

Solana Mainnet Launch

Status: 📋 Planned for Q2 2026Requirements before mainnet:

✅ Anchor program security audit
✅ Shadow Drive persistence complete
✅ 1M+ vector load testing
✅ Beta user feedback incorporated

What changes:

Program deployed to mainnet
Real SOL required for transactions
Production-grade uptime monitoring
Enterprise support available

LangChain Integration

Native LangChain Vector Store

Status: 📋 Planned for Q2 2026Goal: Official langchain-solvec package:

from langchain.vectorstores import SolVec
from langchain.embeddings import OpenAIEmbeddings

vectorstore = SolVec(
    wallet="~/.config/solana/id.json",
    collection_name="langchain-memory",
    embedding_function=OpenAIEmbeddings()
)

vectorstore.add_texts(["Agent learned user prefers dark mode"])
results = vectorstore.similarity_search("What are user preferences?", k=5)

Distribution: PyPI + npm + LangChain official docs

AutoGen Integration

Microsoft AutoGen Memory

Status: 📋 Planned for Q2 2026Goal: Native AutoGen memory backend:

from autogen import AssistantAgent
from autogen.memory import SolVecMemory

assistant = AssistantAgent(
    name="assistant",
    memory=SolVecMemory(wallet="~/.config/solana/id.json")
)

Agents automatically store and recall conversation history with on-chain provenance.

Additional Features

Hybrid Search

Combine vector similarity + keyword filters:

collection.query({
  vector: [...],
  filter: { category: 'legal', year: 2026 },
  topK: 10
})

Collection Snapshots

Time-travel queries against historical Merkle roots:

const results = await collection.queryAtTimestamp({
  timestamp: '2026-01-15T00:00:00Z',
  vector: [...]
})

Multi-Tenancy

Isolated collections per user with wallet-based access control

Rust CLI

Command-line tool for devops and testing:

solvec query my-collection --vector-file embedding.json
solvec verify my-collection
solvec export my-collection > backup.jsonl

Version History

v0.1.0-alpha (March 2026)

Initial alpha release on Solana devnet ✅ Added:

Priority Areas

If you’re interested in contributing, these areas have the highest impact:

Rust HNSW SIMD Optimizations

Goal: Leverage CPU SIMD instructions for faster distance calculationsImpact: 2-3x query speedup on AVX2/AVX-512 CPUsSkills needed: Rust, SIMD, low-level optimization

Shadow Drive Integration

Goal: Production-ready persistence layer with smart cachingImpact: Enables production deployments with restart safetySkills needed: Rust, async I/O, Solana Shadow Drive SDK

LangChain Integration

Goal: Official vector store integrationImpact: Instant distribution to millions of LangChain usersSkills needed: Python, LangChain architecture

Additional Language SDKs

Goal: Go, Rust (native), Ruby, Java SDKsImpact: Broader ecosystem adoptionSkills needed: Target language + SDK design
