ThirdKey builds tools for secure, privacy-first, and verifiable AI agents.
Our flagship project is Symbiont — a next-generation agent framework and programming language built for trust, autonomy, and control.
🌐 Featured Project: Symbiont
Symbiont is a secure, AI-native programming language and multi-agent runtime.
Designed for policy-aware autonomy, Symbiont empowers developers to build zero-trust, privacy-preserving agents that cooperate safely with humans and other systems.
- 🔐 Built with zero-trust security and verifiable behavior
- 🧩 Extensible DSL with tree-sitter parsing and sandboxing
- 🕸️ Agent orchestration, multi-modal context management, and cryptographic signing
- ⚙️ Written in Rust for maximum performance and safety
