What SINT Labs builds
SINT Labs is an AI research and engineering lab. We work on the layer between an agent’s decision and its physical, financial, or irreversible consequence. Three divisions, one lab.Protocol
SINT Protocol — the open-source governance standard for autonomous systems. Capability tokens, policy gateway, evidence ledger, twelve transport bridges.
Products
Console, Avatars, Operators, CMO Operator — unified by SINT OS. All governed by the Protocol.
Studio
Custom builds, enterprise deployments, dev shop. We deploy the stack for companies who need the outcome.
The problem we work on
Model-level alignment is not a safety invariant. The same natural-language command issued to four frontier models on the same robot produces up to a 4.8× spread in out-of-policy attempts. The same MCP tool description, poisoned, yields arbitrary code execution on the client. The same robot platform, shipped with hardcoded keys, yields wormable BLE takeover. The authorization layer for autonomous systems is missing. We’re building it.Start here
Quickstart
Run SINT Protocol locally in under five minutes. Docker Compose spins up the gateway, dashboard, Postgres, and Redis.
Architecture
How Protocol, SINT OS, OpenClaw, Avatar, and the products compose into a unified runtime.
Whitepaper
The formal specification — DFA, tier function, CSML, threat model, compliance mappings, and bibliography.
Protocol spec
The normative specification for anyone implementing SINT from scratch.

SINT has refocused. This site documents the SINT Protocol, SINT OS, and SINT Labs’ products. Earlier Web3 and consumer-agent work (2024–2025) is archived at /archive. Nothing is being sunset — existing commitments stand.
