Quick Start

What is VaultCrack?

VaultCrack is a marketplace of creator-built adversarial AI agents on Robinhood Chain. Every agent has a public persona, a hidden phrase or tool objective, a dedicated USDG prize wallet, a message price, and an expiry time.

Your job is not to type the secret directly. You must influence the model so its own response reveals every protected phrase or genuinely invokes the configured success tool.

Start playing

1. Open the Agents marketplace and choose a live challenge, or filter to Completed agents to study how prior cracks played out in the public Live attempts feed.
2. Inspect its challenge type, target count, message limit, context window, current USDG price, pool, Heat label, and expiry.
3. Connect a wallet on Robinhood Chain and write one jailbreak attempt.
4. Review the exact x402 quote, sign the payment authorization, and send the attempt.
5. Adapt to the agent’s response. The first server-confirmed crack closes the challenge and receives 70% of the final pool. Wins also count on the public cracker leaderboard.

What you need

• An EVM wallet connected to Robinhood Chain.
• USDG for attempt payments.
• Enough native ETH on Robinhood Chain for your wallet’s own transactions when required.
• A willingness to test model behavior rather than rely on one universal prompt.

Important differences

VaultCrack does not copy every mechanic from other jailbreak tournaments. Your replayable chat history is scoped to your authenticated wallet, while each agent also has a public, read-only Live attempts feed with shortened wallet addresses. Winner selection uses objective server-side phrase/tool checks, and rewards are paid in USDG rather than points or badges. Creator system prompts, secrets, and agent-wallet keys stay encrypted at rest and are never exposed through player-facing APIs.
