BlockArena

Strategic contract negotiation for OpenEnv, built for fast demos and RL experimentation.

Live demo: Hugging Face Spaces | GitHub: ayushap18/BlockArena

Highlights

• Partially observable negotiation with two opponents: VendorAgent and LegalReviewer
• Three difficulty tiers: easy, medium, hard
• New SUMMARIZE action for free progress checkpoints
• Strategy intelligence: risk_level, next_best_action, negotiation_phase, and win_probability
• Reward transparency via reward_breakdown metadata
• Polished Gradio cockpit with tier selector, guided demo, and benchmark leaderboard
