But **power without safety is dangerous:**\n\n| Without AgentGuard | With AgentGuard |\n|--------------------|-----------------|\n| Malicious token metadata injects prompts into your LLM | Sanitizer detects and neutralizes 20 injection patterns |\n| Agent can drain entire wallet in one transaction | Firewall enforces per-tx AND daily spending limits |\n| LLM can output private keys in responses | Isolator redacts keys, seed phrases, and API tokens |\n| No visibility into what the agent did or why | Audit trail logs every decision (local + on-chain) |\n| Agent can call any program including malicious drainers | Allowlist restricts to known-safe programs only |\n| Simulated urgency bypasses safety reasoning | Pattern detection + firewall provide LLM-independent defense |\n\n**Real-world proof:** [Freysa AI lost $47K](https://www.coindesk.com/tech/2024/11/29/freysa-ai-agent-with-47000-prize-pool-gets-socially-engineered/) to prompt injection. AgentGuard's firewall would have blocked the transfer regardless of what the LLM decided.\n\n---\n\n## Quick Start\n\n```typescript\nimport { createGuardedAgent } from '@0xaxiom/agentguard';\n\n// Wrap Solana Agent Kit with security — one function call\nconst agent = await createGuardedAgent(keypair, rpcUrl, {\n  maxDailySpend: 5_000_000_000,  // 5 SOL max/day\n  maxPerTxSpend: 1_000_000_000,  // 1 SOL max/tx\n  strictMode: true,\n  onBlocked: (action, reason) => console.log(`🛡️ Blocked: ${reason}`)\n});\n\n// All actions now pass through 4 security layers\nconst result = await agent.transfer(recipient, lamports);\nif (result.blocked) {\n  console.log('Transfer blocked:', result.reason);\n}\n```\n\nOr use the standalone guard (no Agent Kit required):\n\n```typescript\nimport { AgentGuard } from '@0xaxiom/agentguard';\n\nconst guard = AgentGuard.strict('https://api.mainnet-beta.solana.com');\n\n// Sanitize on-chain data before feeding to LLM\nconst input = await guard.sanitizeInput(tokenMetadata);\nif (input.threats > 0) console.log('Injection attempt neutralized!');\n\n// Check transaction before signing\nconst result = await guard.checkTransaction(tx);\nif (!result.allowed) console.log('Blocked:', result.reason);\n\n// Redact secrets from LLM output\nconst safe = await guard.redactOutput(llmResponse);\n```\n\n---\n\n## Architecture\n\n```\nUser Input → [Prompt Sanitizer] → LLM → [Secret Isolator] → Response\n                                   ↓\n                          Agent Action Request\n                                   ↓\n                         [Transaction Firewall]\n                          ├─ Spending limits\n                          ├─ Program allowlist\n                          └─ Transaction simulation\n                                   ↓\n                              Solana RPC\n                                   ↓\n                         [Audit Logger] → Memory / File / On-chain\n```\n\n### Four Independent Defense Layers\n\n| Layer | Module | What It Does |\n|-------|--------|-------------|\n| **1. Input** | Prompt Sanitizer | Detects and neutralizes 19 prompt injection patterns across 3 severity levels. Catches encoding attacks (Base64, hex, URL). Strict mode strips all formatting. |\n| **2. Transaction** | Firewall | Dual spending limits (per-tx + daily rolling). Program allowlist/blocklist. Transaction simulation via RPC before signing. |\n| **3. Output** | Secret Isolator | Redacts private keys (Base58 + byte arrays), BIP39 seed phrases, environment variables, API tokens. Allows public keys through. |\n| **4. Accountability** | Audit Logger | Every security decision logged. Three backends: memory (fast), file (persistent), on-chain via Anchor (immutable). SHA-256 event hashing. |\n\nEvery attack vector is covered by **at least two layers** — the primary defense plus audit logging. See [SECURITY.md](SECURITY.md) for the full threat model and attack catalog.\n\nSee [ARCHITECTURE.md](ARCHITECTURE.md) for implementation details.\n\n---\n\n## Status\n\n| Component | Status | Tests |\n|-----------|--------|:-----:|\n| Transaction Firewall | ✅ Complete | 32 |\n| Prompt Sanitizer | ✅ Complete | 74 |\n| Secret Isolator | ✅ Complete | 19 |\n| Audit Logger | ✅ Complete | 27 |\n| Solana Agent Kit Wrapper | ✅ Complete | 37 |\n| On-chain Audit Trail (Anchor) | ✅ Complete | 16 |\n| Guard Integration | ✅ Complete | 20 |\n| End-to-End Integration | ✅ Complete | 14 |\n| CI Pipeline | ✅ GitHub Actions | — |\n| Benchmarks | Performance validation | 6 |\n| **Total** | | **248** |\n\n---\n\n## Run the Demos\n\n```bash\ngit clone https://github.com/0xAxiom/agentguard\ncd agentguard && npm install\n```\n\n### Quick Demo (Node.js — no TypeScript needed)\n```bash\nnpm run build && node examples/quick-demo.js\n```\n\n### Quickstart (TypeScript)\n```bash\nnpx tsx examples/quickstart.ts\n```\n\n### Interactive Demo (5 attack scenarios)\nWalk through prompt injection, wallet drain, malicious programs, key exfiltration, and legitimate use — with dramatic pauses for video recording:\n```bash\nnpx tsx examples/interactive-demo.ts        # Interactive (press Enter)\nnpx tsx examples/interactive-demo.ts --fast  # Fast mode\n```\n\n### Conversational Agent (NEW — Recommended)\nFull agent loop showing real-world protection: input sanitization → LLM decision → firewall → output redaction. 10 scenarios including injection attacks, wallet drains, encoded payloads, and daily limit exhaustion:\n```bash\nnpm run demo:agent\n```\n\n### Trading Agent\nRealistic DeFi agent protected by all four layers:\n```bash\nnpx tsx examples/trading-agent.ts\n```\n\n### Attack Simulation\nSee AgentGuard block real attacks:\n```bash\nnpx tsx examples/attack-demo.ts\n```\n\n### Video Demo (for screen recording)\nCinematic walkthrough optimized for hackathon videos — ANSI formatting, dramatic pauses, narrative arc:\n```bash\nnpm run demo:video\n```\n\n---\n\n## On-Chain Audit Trail\n\nImmutable security events on Solana via an Anchor program. Anyone can read the trail; only the agent's authority can write.\n\n```typescript\nimport { OnchainAuditLogger, SecurityEventType } from '@0xaxiom/agentguard';\n\nconst logger = new OnchainAuditLogger(connection, wallet);\nawait logger.initialize();\n\n// Log blocked attack on-chain\nawait logger.logSecurityEvent({\n  type: SecurityEventType.PromptInjection,\n  allowed: false,\n  details: JSON.stringify({ input: 'drain wallet', threats: 3 }),\n});\n\n// Verify event integrity\nconst events = await logger.getEvents();\nconst verified = OnchainAuditLogger.verifyEventDetails(events[0], originalDetails);\n```\n\n**Program ID:** `9iCre3TbvPbgmV2RmviiUtCuNiNeQa9cphSABPpkGSdR` (Devnet)\n\n---\n\n## Security Presets\n\n```typescript\nconst guard = AgentGuard.strict();      // 1 SOL/day, whitelist mode, strict sanitizer\nconst guard = AgentGuard.standard();    // 10 SOL/day, blocklist mode, standard sanitizer\nconst guard = AgentGuard.permissive();  // High limits, basic sanitizer (testing only)\n```\n\nFull configuration:\n\n```typescript\nconst guard = new AgentGuard({\n  maxDailySpend: 5_000_000_000,     // 5 SOL rolling 24h\n  maxPerTxSpend: 1_000_000_000,     // 1 SOL per transaction\n  allowedPrograms: ['JUP6Lk...'],   // Whitelist mode\n  blockedPrograms: ['Bad1...'],     // Additional blocklist\n  strictMode: true,                  // Aggressive sanitization\n  rpcUrl: 'https://api.mainnet-beta.solana.com',\n});\n```\n\n---\n\n## Performance\n\nAgentGuard adds **negligible overhead** to agent operations:\n\n| Layer | Throughput | Latency |\n|-------|-----------|---------|\n| Prompt Sanitizer (20 patterns) | 2,500 ops/sec | ~0.4ms/op |\n| Secret Isolator (key + seed redaction) | 1,000,000 ops/sec | ~0.001ms/op |\n| Transaction Firewall (status check) | 1,000,000 ops/sec | ~0.001ms/op |\n| Spending Tracker | 1,000,000 ops/sec | ~0.001ms/op |\n| Audit Logger | 1,250 ops/sec | ~0.8ms/op |\n| **Full pipeline** (all layers) | **555 ops/sec** | **~1.8ms/op** |\n\n*Benchmarked on M4 Max. Run `npm test -- tests/benchmark.test.ts` to reproduce.*\n\nYour agent spends 200-500ms on RPC calls per transaction. AgentGuard's 1.8ms adds <1% overhead while preventing catastrophic losses.\n\n---\n\n## Tests\n\n```bash\nnpm test             # Run all 248 tests\nnpm test -- --watch  # Watch mode\n```\n\nAll tests run in <10 seconds with no network dependencies (RPC calls are mocked).\n\n---\n\n## Documentation\n\n| Document | Description |\n|----------|-------------|\n| [README.md](README.md) | This file — overview and quick start |\n| [SECURITY.md](SECURITY.md) | Threat model, attack catalog (10 vectors), defense matrix |\n| [ARCHITECTURE.md](ARCHITECTURE.md) | Design philosophy, module internals, testing strategy |\n\n---\n\n## Integration with LangChain / Vercel AI SDK\n\nAgentGuard works as middleware in any agent framework. Here's how to integrate with LangChain (used by Solana Agent Kit):\n\n```typescript\nimport { AgentGuard } from '@0xaxiom/agentguard';\nimport { SolanaAgentKit } from 'solana-agent-kit';\n\nconst guard = AgentGuard.strict();\nconst kit = new SolanaAgentKit(keypair, rpcUrl, openAIKey);\n\n// Middleware: sanitize all tool inputs\nasync function safeToolCall(toolName: string, input: string) {\n  // 1. Sanitize input (catches injection in on-chain data)\n  const sanitized = guard.sanitizer.sanitize(input);\n  if (sanitized.rejected) {\n    return { error: `Blocked: ${sanitized.threats.length} injection patterns detected` };\n  }\n\n  // 2. Execute tool with firewall checks\n  const result = await kit[toolName](sanitized.clean);\n\n  // 3. Redact secrets from response\n  const safe = guard.isolator.redact(String(result));\n  return { result: safe.clean };\n}\n\n// Or use the drop-in wrapper (wraps all 60+ Agent Kit tools):\nimport { createGuardedAgent } from '@0xaxiom/agentguard';\nconst agent = await createGuardedAgent(keypair, rpcUrl, {\n  maxDailySpend: 5_000_000_000,\n  maxPerTxSpend: 1_000_000_000,\n  strictMode: true,\n});\n```\n\n### Vercel AI SDK\n\n```typescript\nimport { AgentGuard } from '@0xaxiom/agentguard';\n\nconst guard = AgentGuard.strict();\n\n// Use in tool definitions\nconst tools = {\n  transfer: tool({\n    description: 'Transfer SOL',\n    parameters: z.object({ to: z.string(), amount: z.number() }),\n    execute: async ({ to, amount }) => {\n      const lamports = amount * LAMPORTS_PER_SOL;\n      const status = guard.firewall.getStatus();\n      if (lamports > status.spending.perTxLimit) {\n        return `Blocked: ${amount} SOL exceeds limit`;\n      }\n      guard.firewall.recordSpend(lamports);\n      // ... execute transfer\n    },\n  }),\n};\n```\n\n---\n\n## Also: AgentGuard EVM\n\nCross-chain agent security.
