Onchain Agent OS
Build agents on any AI model and any chain.
Deploy agents with their own wallets & track agents you already run. All from your own machine.
Self-hosted on macOS & Linux (Windows via WSL) · your keys never leave your machine · one-time license, instant download + key · trades through the rail pay a disclosed fee (see the license section)
Your agent dashboard
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. It runs on that schedule, inside that budget.
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 and Polygon are built in.
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 transfers, swaps, x402 payments and scheduled tasks already set up. It keeps running on your machine on the schedule you set.
Plus Solana, Arbitrum, Optimism & Polygon — balances, activity, and policy on every chain.
Built and proven on Base
Built-in standards
Every new agent starts with them. Live on Base today.
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
Run every agent from one chat
Hermes turns one request 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
Keys stay on your machine
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. You can read all of it.
- 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
Spend limits and receipts
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

One-time licence. Trades routed through the Sato OS rail also pay 3 / 15 bps on spot swaps (stable-to-stable / any volatile leg) and a 3 bps builder fee on perps, taken inside the transaction you sign; there is no cross-chain tier, and a failed or skipped trade pays nothing. Every quote states the fee first.

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.
