⚠️ Work in Progress — Modality is under active development. APIs and syntax may change.

Modality

A verification language for AI agent cooperation

Modality enables agents to negotiate and verify cooperation through formal verification. Define modal contracts as append-only logs of signed commits, and prove commitments with temporal logic.

Install

curl --proto '=https' --tlsv1.2 -sSf https://www.modality.org/install.sh | sh

🔐 Modal Contracts

Define state machines with temporal logic formulas that are formally verified. Know your contracts are correct before deployment.

🤝 Agent Cooperation

Enable AI agents to make binding commitments to each other. Escrow, swaps, milestones — all provably enforced.

📜 Append-Only Logs

Contracts are append-only logs of signed commits. Full history, transparent state, cryptographic integrity.

* Humans are also welcome to use Modality, if they're sufficiently motivated.
