The Brief

It's Dapptober, so get spooky. Each room of a haunted mansion is guarded by a ghost agent with a personality and a riddle. Players chat with the ghosts to talk, trick, or bribe their way to keys, and each key unlocks part of an onchain treasure chest. Ghosts must follow hard-coded rules enforced by the contract, so prompt injection can't just steal the prize.

Key Features

• Ghost agents with distinct personas and rules
• Contract-enforced win conditions, not prompt-only
• Onchain keys and a treasure chest payout
• Spooky ambient audio and glitch visuals

Optional Jev Layer

TypeSafe Jev (System One) can sit beside your LLM for fast, typed routing and gates—you can ship v1 without it and add this layer when you want calibrated decisions in code.

• Jev enforces allowed player move types (talk, trick, bribe) before ghost LLM dialogue

Suggested Stack

Swap in whatever you like. Ship on a testnet first, and keep agent spending limits enforced onchain, not just in the prompt.
