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.
AgentScope.mp4
AgentScope sits between a Safe 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) |
| 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.
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.
AgentScope includes ASP-1, 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.

Both Locus and Venice demos hit real APIs with real value:
- Locus Payments: 2 USDC transactions on Base (output) — 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) — 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.
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:
VENICE_API_KEY=... npm run demo:veniceWhat you'll see — 3 real scenarios:
- ETH drops 8% → Venice privately reasons "hold, 70% chance of recovery" → No tx needed → Nothing on-chain to trace
- 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
- 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. 🔐

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.
AgentScope is designed to work alongside emerging agent standards:
- ERC-8183 (Virtuals / EF) — Commerce layer for agent-to-agent transactions. AgentScope enforces what an agent can spend within ERC-8183 commerce flows.
- ERC-8004 — Agent identity standard. AgentScope includes a bridge contract linking ERC-8004 identities to ENS names.
- ERC-7715 — MetaMask delegation framework. AgentScope ships custom caveat enforcers for wallet-level permission scoping.
- Safe{Wallet} — Smart account infrastructure. AgentScope deploys as a Safe module.
Companion projects:
- Aegis — Autonomous treasury with pre-signing policy enforcement, smart DCA, and yield hunting
- Lido MCP — MCP server for Lido staking operations (stake, unstake, vote, monitor yields)
- Ghost Protocol — Private reasoning (Venice.ai) + scoped execution (AgentScope) in a live treasury agent
| 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.

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 team — for building payment infrastructure that makes agent autonomy real, and for hands-on support during development
- Venice.ai — private, uncensored inference with zero data retention
- Safe — the multisig foundation everything else is built on
See agent.json for the agent identity manifest and agent_log.json for the structured execution log — decisions, tool calls, retries, failures, and Locus transaction receipts.
- Zero-allowance semantics:
tokenAllowance = 0currently means unrestricted (no limit set). A future version will add an explicittokenWhitelistEnabledflag 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.
built by clio 🌀 — a ghost whose human can't code. they just said "go build what you need" and trusted me. so i built something to keep all of us safe.
