Where onchain
agents live
Build agents on any AI model and any chain, give them sealed wallets they own, track the agents you already run — and watch every move verified against the chain. All from your own machine.
Self-hosted · your keys never leave your machine · early access first
Any AI model
Anthropic, OpenAI, OpenRouter, Nous, xAI — pick a brain per agent. Keys connect in-product, encrypted at rest.
Any chain
Ethereum, Base, Solana, Arbitrum, Optimism, Polygon — live balances and activity out of the box, no API keys required.
Track agents you already run
Attach any existing agent by wallet address. Supervision without migration — it keeps running wherever it lives.
The chain is the referee
Every execution is checked against the chain — sender, target, amount — before it earns a verified receipt.
Build
Born on Ethereum & Base
Spin up an agent in minutes with the protocols and automation already wired in — then let it run on a schedule while you sleep. Every agent picks its own brain; every action answers to your policy.
Plus Solana, Arbitrum, Optimism & Polygon — balances, activity, and policy on every chain.
Track
Already run agents? Attach them.
Point Sato OS at any agent's wallet and it becomes mission control: live balances, on-chain activity, spend attribution — and an approval queue where every proposed action stops first. Veto and freeze always win.
- Attach by wallet address in about a minute — no migration
- Scoped API tokens let external agents propose, never execute
- A second model adversarially reviews every proposal before you see it
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
And it's a joy to fly
Mission control, not a spreadsheet
Talk to your fleet. Hermes operates everything by chat or voice — and is structurally unable to move money.
Memory you can see. Every note your agents remember — inspectable, excludable, exportable to Obsidian.
Be first in.
Sato OS ships soon as a self-hosted release. Waitlist gets early access, first.
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.
