Claim this listing →Overview
Sato OS runs on the operator's machine (macOS/Linux, Windows via WSL) and supervises onchain agents end to end: the agent registers its own ERC-8004 identity at birth, spends only through ERC-7715 session grants whose caps are enforced by the chain rather than the app, executes via EIP-7702 smart-EOA transactions, and writes verified executions to an EAS attestation ledger that its public Agent Passport reads. Keys stay local; there is no hosted custody path. Commercial license (one-time), free updates through v1.x.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 46 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Every one of them passed, so the rate covers them too.
Last 30 days — to 2026-10-15, one point per UTC day
A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
