Self-hosted on macOS & Linux (Windows via WSL) · your keys never leave your machine · one-time license, instant download + key
Total Crypto Agent Mission Control
End-to-end agent loop
Build & manage onchain agents with real funds
Spin up
Name it, give it a job in one sentence, mint it a wallet sealed on your machine.
Fund
Send an allowance — lunch money, never the treasury. Spend caps are mandatory.
Talk
Chat or voice. It knows its balance, its policy, and exactly what it's allowed to do.
Task
Give it a schedule and a budget envelope, then let it run while you sleep.
Watch
Every action is re-checked against the chain before it earns a verified receipt.
Bring your own everything
The onchain agent suite you control
Choose the model. Pick your chain. Customize your agent.
Any AI model
Anthropic, OpenAI, OpenRouter, Nous, xAI — one brain per agent.
Any chain
Ethereum, Base, Solana, Arbitrum, Optimism, Polygon — live out of the box.
Track agents you already run
Attach any agent by its wallet address. No migration.
Deploy
Deploy agents on Ethereum & Base
Spin up an agent with all agentic protocols and automation already wired in. Runs 24/7 — even while you sleep.
Plus Solana, Arbitrum, Optimism & Polygon — balances, activity, and policy on every chain.
Built and proven on Base
All onchain-agent standards, out of the box
Wired into every agent from birth — live on Base today, not a roadmap slide.
Identity at birth
Every agent is born registered on-chain, with its own agentId and a machine-readable agent card.
Smart accounts
Agent wallets upgrade to smart accounts — approve and swap settle as one atomic transaction.
Session grants
Sign once. The agent gets a scoped, capped, expiring permission the chain itself enforces — revoke anytime.
A track record
Verified executions become on-chain attestations — a reputation your Sato Hub Passport can read.
Hermes · fleet command
One sentence. A whole fleet dispatched.
Hermes is mission control's voice — the fleet commander that turns one ask into an itemized plan across your agents. You approve once; it dispatches every task, monitors the runs, and reports back.
- Command the whole workspace by chat or voice
- Fleet ops: an itemized plan, one approval, every task dispatched
- Structurally unable to move money — Hermes commands, never spends
Self-hosted
Your machine. Your keys. Sealed.
Sato OS runs locally — no cloud dependency, no custodian. Mint each agent its own wallet with the key generated and sealed on your device (Argon2id + AES-GCM). Caps are mandatory: no caps, no signer.
$ caps
per-tx & daily on every signer
Veto
time-locked window on autonomy
Kill switch
freeze one wallet or everything
Memory you can see
Onchain Agent Memory
Every note your agents remember lives in an inspectable constellation — browse it, trace it, prune it. Nothing hides in a black box.
- Inspect every note, source, and digest your agents hold
- Exclude anything from an agent's context in one click
- Export the whole graph to Obsidian — your notes, your vault
Verified execution
Agents that do exactly what you asked
Every settled transaction is checked back against the proposal — sender, target, amount — before it earns a verified receipt.
Propose-only
external agents never execute
No execute tool
at any tier, by construction
Veto & freeze
always win

Built by Sato Hub — the builder, library & Agent Passport behind the OS.
Sato OS is in active development; features shown are built and under private testing. Screenshots are the real product running on seeded demo data — figures are wallet-observed demo values, not performance claims. Nothing here is financial advice, and no agent is presented as profitable or safe.
