Install

npm install @walraxc/memwal-rag

Quick Start

import { ExploitRAG } from "@walraxc/memwal-rag";

const rag = ExploitRAG.init({
  privateKey: process.env.MEMWAL_PRIVATE_KEY!,
  accountId:  process.env.MEMWAL_ACCOUNT_ID!,
  namespace:  "raxc/defi-cases", // 781 patterns pre-seeded
});

// Search for similar exploits
const matches = await rag.search("reentrancy external call before state update");

matches.forEach(m => {
  console.log(`[${(m.score * 100).toFixed(1)}%] ${m.content.slice(0, 100)}`);
});
// [74.7%] DAO reentrancy pattern — external call before balance update...
// [68.2%] Unchecked external call in withdraw function...
// ...

API

ExploitRAG.init(config)

| Param | Type | Description | |---|---|---| | privateKey | string | MemWal private key (hex) | | accountId | string | MemWal account ID (0x...) | | serverUrl | string? | Default: https://relayer.memory.walrus.xyz | | namespace | string? | Default: raxc/defi-cases |

rag.search(query, limit?)

Returns RagMatch[] sorted by score:

{ id: string, score: number, content: string }

rag.seed(patterns[], onProgress?)

Seed custom patterns into a namespace. Returns count seeded.

Why MemWal?

• No embedding API calls → zero cost
• Namespace isolation → your data, your namespace
• Encrypted at rest → patterns stay private
• Semantic search → finds similar exploits, not just keyword matches
