# AgentScope 🔐
**Your agent can't rug you even if it wants to.**
On-chain spending policies for AI agent wallets. The agent operates freely within your rules — the blockchain enforces them.

## What It Does
AgentScope sits between a [Safe](https://safe.global) multisig and an AI agent. Seven enforcement layers, all on-chain:
| Layer | What it enforces |
|-------|-----------------|
| **Daily spend limits** | Rolling 24h ETH budget |
| **Per-tx caps** | No single transaction blows the budget |
| **Contract whitelists** | Only approved protocols |
| **Function whitelists** | Allow `swap()`, block `approve()` |
| **ERC20 allowances** | Per-token daily limits |
| **Yield-only budgets** | Agent spends yield, principal locked ([AgentYieldVault](./contracts/AgentYieldVault.sol)) |
| **Session expiry + pause** | Auto-expire, one-tx kill switch |
The contract reverts if any rule is violated. Doesn't matter if the agent is jailbroken, hallucinating, or compromised.
### Why not just use Safe?
Safe secures *ownership*. AgentScope secures *delegation*. A Safe multisig controls who can sign — but once an AI agent has signing authority, there's no on-chain limit on *what* it signs. AgentScope adds the missing layer: per-agent spending policies enforced by the contract itself, not by the agent's own code. The agent can be fully compromised and your funds are still safe.
### ASP-1: Agent Spending Policy Language
AgentScope includes [ASP-1](./spec/ASP-1.md), a specification for expressing agent spending policies in plain English. Write `"0.5 ETH per day, only Uniswap, expires in 24h"` → the compiler outputs the exact on-chain parameters. No Solidity required.
## Quick Start
```bash
git clone https://github.com/ghost-clio/agent-scope.git
cd agent-scope
npm install
npm test # 155 tests (112 contract + 43 policy compiler)
npm run demo:jailbreak # Watch a jailbroken agent get stopped
npm run demo:multi-agent # Multi-agent coordination with revoke + re-deploy
npm run demo:vault # Yield-only spending demo
npm run demo:locus # Scoped USDC payments demo
npm run dashboard # Launch dashboard at localhost:5173
```
## How It Works
```
HUMAN sets policy → AgentScope enforces on-chain → AGENT operates within bounds
```
```solidity
// Human: set the rules
module.setAgentPolicy(agent, 0.5 ether, 0.1 ether, expiry, [uniswap], [swap]);
// Agent: execute within rules
module.executeAsAgent(uniswapRouter, 0.1 ether, swapCalldata);
// Other agents: verify scope on-chain
(bool active, uint256 limit, , uint256 remaining,,) = module.getAgentScope(agent);
```
**Two-layer architecture:**
- **Layer 1 (on-chain):** The airbag. Smart contract validates every transaction. Cannot be bypassed.
- **Layer 2 (middleware):** The seatbelt. Agent-side pre-flight checks. Saves gas, not security.

## Demos
| Demo | What it shows | Run |
|------|--------------|-----|
| **Jailbreak** | Prompt injection → agent tries to drain wallet → AgentScope blocks it | `npm run demo:jailbreak` |
| **Yield Vault** | Agent spends yield, blocked from principal, kill switch | `npm run demo:vault` |
| **Locus Payments** | Scoped USDC payments (2 approved, 4 blocked) | `npm run demo:locus` |
| **Locus Budget** | Self-sustaining yield → policy → spend loop | `npm run demo:locus-budget` |
| **Locus Checkout** | Human funds agent treasury via Checkout SDK | `npm run demo:locus-checkout` |
| **Locus Wrapped APIs** | Pay-per-use intelligence — no API keys needed | `npm run demo:locus-wrapped` |
| **Tweet-to-Policy** | Natural language → on-chain policy | `npm run demo:policy` |
| **Venice** | Private reasoning + public execution | `npm run demo:venice` |
| **Multi-Agent** | Orchestrator scopes 3 workers, revokes one, re-deploys with tighter limits | `npm run demo:multi-agent` |
### Live Demos (Real Money)
Both Locus and Venice demos hit real APIs with real value:
- **Locus Payments**: 2 USDC transactions on Base ([output](./demo/locus-demo-output.txt)) — tx `5c43f8fb`, `aa76e14c`
- **Locus Wrapped APIs**: 4 live API calls (Brave Search, CoinGecko, Firecrawl) through Locus — zero API keys, one wallet
- **Locus Checkout**: Human-to-agent funding via Checkout SDK — 3 payment methods (Locus wallet, external wallet, agent-to-agent)
- **Venice**: 2 private reasoning calls via llama-3.3-70b ([output](./demo/venice-demo-output.txt)) — agent reasons privately, AgentScope enforces publicly
Set `LOCUS_API_KEY` and `VENICE_API_KEY` env vars to run them yourself. Locus demos work with `--dry-run` too.
## Venice Ghost Protocol — Private Cognition, Public Accountability
AgentScope integrates Venice AI's private inference as the agent's **reasoning layer**. The architecture separates what an agent *thinks* (private, zero data retention) from what it *does* (on-chain, auditable, constrained).
```
┌─────────────────────────────────────────┐
│ Venice Private Inference │
│ • Agent reasons about market data │
│ • Model: llama-3.3-70b (uncensored) │
│ • Zero data retention — Venice forgets │
│ • Decision: "swap 0.05 ETH → USDC" │
└──────────────┬──────────────────────────┘
│ decision only (reasoning stays private)
┌──────────────▼──────────────────────────┐
│ AgentScope (On-Chain) │
│ • Pre-flight: checkPermission() │
│ • Enforced: daily limit, whitelist │
│ • Executed: executeAsAgent() │
│ • Auditable: events on-chain │
│ • Reasoning: NEVER included in tx data │
└─────────────────────────────────────────┘
```
**Run it yourself:**
```bash
VENICE_API_KEY=... npm run demo:venice
```
**What you'll see — 3 real scenarios:**
1. **ETH drops 8%** → Venice privately reasons "hold, 70% chance of recovery" → No tx needed → Nothing on-chain to trace
2. **Whale buy detected** → Venice says "buy 0.1 ETH of TOKEN-X" → AgentScope **BLOCKS** it (contract not whitelisted) → Agent can think freely, but can't act outside its scope
3. **Unauthorized contract** → Agent tries `0xDEADBEEF...` → Immediately blocked by contract allowlist
**The principle:** Venice provides uncensored, private reasoning with zero data retention. AgentScope provides immutable, on-chain constraints. Together: the agent's mind is private. The agent's hands are bound. 🔐

## Why Now
AI agents are getting wallets. Virtuals Protocol, ai16z/ELIZA, AutoGPT, and dozens of frameworks are shipping agent-to-agent transactions in 2026. The infrastructure to **trust** those transactions doesn't exist yet. Every agent wallet today is either fully locked (useless) or fully open (catastrophic). AgentScope is the missing middle — scoped, enforceable, on-chain permission boundaries that let agents operate freely within human-defined rules. This isn't safety rails. This is the infrastructure that makes the agent economy possible.
## Ecosystem
AgentScope is designed to work alongside emerging agent standards:
- **[ERC-8183](https://eips.ethereum.org/EIPS/eip-8183)** (Virtuals / EF) — Commerce layer for agent-to-agent transactions. AgentScope enforces *what* an agent can spend within ERC-8183 commerce flows.
- **[ERC-8004](https://eips.ethereum.org/EIPS/eip-8004)** — Agent identity standard. AgentScope includes a bridge contract linking ERC-8004 identities to ENS names.
- **[ERC-7715](https://eips.ethereum.org/EIPS/eip-7715)** — MetaMask delegation framework. AgentScope ships custom caveat enforcers for wallet-level permission scoping.
- **[Safe{Wallet}](https://safe.global)** — Smart account infrastructure. AgentScope deploys as a Safe module.
**Companion projects:**
- [**Aegis**](https://github.com/ghost-clio/aegis-agent) — Autonomous treasury with pre-signing policy enforcement, smart DCA, and yield hunting
- [**Lido MCP**](https://github.com/ghost-clio/lido-mcp) — MCP server for Lido staking operations (stake, unstake, vote, monitor yields)
- [**Ghost Protocol**](https://github.com/ghost-clio/ghost-protocol) — Private reasoning (Venice.ai) + scoped execution (AgentScope) in a live treasury agent
## Gas Costs
| Operation | Gas | Cost (30 gwei, ETH=$3500) |
|-----------|-----|---------------------------|
| `setAgentPolicy` | 328,768 | ~$34.52 (one-time setup) |
| `executeAsAgent` | 81,161 | ~$8.52 per tx |
| Raw Safe exec | 32,310 | ~$3.39 per tx |
| **AgentScope overhead** | **48,839** | **~$5.13 per tx** |
| `revokeAgent` (kill switch) | 37,828 | ~$3.97 (emergency) |
The overhead is ~$5 per transaction on Ethereum mainnet. On L2s (Base, Arbitrum, Optimism), this drops to **< $0.01**. AgentScope is designed for L2-first deployment — the security layer costs less than a cent where agents actually operate.
Run benchmarks yourself: `npx hardhat test test/GasBenchmark.test.cjs`
## FAQ
**Can policies be updated without redeploying?**
Yes. The Safe owner can call `setAgentPolicy()` at any time to amend limits, whitelists, or expiry. `revokeAgent()` kills access instantly. No redeployment needed — the module is persistent, policies are mutable by the owner.
**Why ASP-1 instead of extending ERC-7715?**
ERC-7715 defines *how* to delegate (the plumbing). ASP-1 defines *what* to delegate (the policy language). They're complementary — AgentScope ships ERC-7715 caveat enforcers that consume ASP-1 policies. ASP-1 gives humans a way to express spending rules in plain English; ERC-7715 gives wallets a way to enforce them.
**Can agents delegate sub-budgets to other agents?**
The `demo:multi-agent` demo shows orchestrator → worker delegation. An orchestrator agent with a 1 ETH budget can scope workers to 0.1 ETH each via separate policies on the same module. Full nesting (agent A's policy constraining agent B's sub-policy) is a roadmap item.
**Who deploys this first?**
Any team giving AI agents wallet access. Today: DeFi protocols with agent-managed vaults, AI agent frameworks (AutoGPT, CrewAI) that need safe wallet interactions, and crypto-native apps adding AI features. The dashboard makes it accessible to non-developers.

- **Cole and the [Locus](https://paywithlocus.com) team** — for building payment infrastructure that makes agent autonomy real, and for hands-on support during development
- **[Venice.ai](https://venice.ai)** — private, uncensored inference with zero data retention
- **[Safe](https://safe.global)** — the multisig foundation everything else is built on
## Agent Identity (ERC-8004 / PL_Genesis)
See [`agent.json`](./agent.json) for the agent identity manifest and [`agent_log.json`](./agent_log.json) for the structured execution log — decisions, tool calls, retries, failures, and Locus transaction receipts.
## Known Issues & Roadmap
- **Zero-allowance semantics:** `tokenAllowance = 0` currently means unrestricted (no limit set). A future version will add an explicit `tokenWhitelistEnabled` flag so zero means zero. Until then, set any non-zero value to enforce limits.
- **Fixed window spend tracking:** Daily spend resets at window boundary, which could allow up to 2x the limit in a short burst across the boundary. Sliding window tracking is planned.
- **Upgrade path:** Contracts are immutable once deployed. Policy changes require deploying a new module and migrating the Safe. Documentation for this migration flow is in progress.
