Does Sato Swap hold my funds or keys?
No. Sato Swap returns unsigned objects — a recommendation, or an unsigned transaction you sign with your own wallet. It holds no key, signs nothing, broadcasts nothing and never takes custody, as of 2026-09-15.
The non-custodial invariant, stated per part of the path. Every row is a property of the code, not a policy that could be changed by configuration.
| Part of the path | What happens |
|---|---|
| Keys | Sato Swap holds none. It generates none, asks for none, and stores none. Nothing in the path can sign. |
| Funds | Never held, netted or forwarded. The fee is a parameter on the venue's own quote, taken by the venue's router inside the transaction you sign. |
| recommend mode | Returns a chosen venue, the reasons, the fee sentence and the verdicts. Never calldata, whatever the gate said. |
| build-tx mode | Returns the same, plus an UNSIGNED transaction — and only when the gate allowed it and a simulation did not revert. You sign it or you throw it away. |
| Broadcasting | Not done here. Nothing is submitted to a chain by Sato Hub on a requester's behalf. |
| Response signatures | An Ed25519 signature over the body proves who said this. It never proves that anyone authorised a transfer. |
| intent-post | Deliberately absent. It is the one mode that would move us from handing back an unsigned object to relaying a signed one, and it is not built. |
How this was answered
The non-custodial invariant asserted across lib/swap/execute.ts and lib/route/adapters/types.ts: every mode returns unsigned objects, and no module in the path holds a key, signs or broadcasts.
Every answer on this page is produced by one named function over Sato Hub's live records on the date shown. Nothing is typed by hand, no figure is carried over from a previous day, and an answer with nothing behind it says unknown rather than zero. The Sato Score measures how open, active and verifiable a project is — it is not a safety, quality or returns grade.
