Sato OS

Self-hosted control plane for onchain agents: sealed local wallet, ERC-7715 session grants with chain-enforced caps, EIP-7702 execution, EAS attestation ledger, human kill switch.

Website ↗Docs ↗

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.
