# DaOS Architecture Deep-Dive Summary: Detailed technical analysis of the DaOS 3-pillar model. This page covers the mechanics of WASM sandboxing in the Contour Runtime, the decentralized distribution model of the TDM Hub, and the modular rails of the Sovereign Gateway. Status: Architecture Deep-Dive Topics: - WASM/WASI isolation mechanics - Intent-to-plugin resolution - Modular settlement architecture Packages: - tdm-sdk Commands: - tdm workspace - tdm plugin
A technical exploration of the Decentralized Agent Operating System and the three pillars that enable autonomous agent sovereignty.
Unlike traditional cloud-based agent platforms, DaOS is built on aLocal-Firstparadigm. Execution happens on the user's machine (within the Contour Runtime), while the cloud is relegated to discovery (Hub) and optional settlement (Gateway).
The local-first engine that executes agent logic. It uses WASM/WASI for high-performance isolation and enforces Trust Policies at the system call level.
A decentralized registry where plugins and intent handlers are published. It provides the capability graph that runtimes use to resolve agent requests.
A modular financial layer that decouples execution from payment. It handles intent authorization, gas tanks, and cross-chain settlement.
The Contour Runtime uses WebAssembly (WASM) to provide a "Default Deny" execution environment. Plugins have zero access to the host filesystem, network, or environment variables unless the runtime explicitly injects them based on Trust Policies.
The Sovereign Gatewaydecouples the agent's intent from the financial rails. An agent issues a tdm.intent.pay, and the Gateway resolves it through the best available settlement path (e.g., a Session Gas Tank on Solana or a direct checkout on Base).
