For research purposes, Bluff fits the broad category of prediction-market venue; detailed model unverified. The launch facts connect it with binary formats across Arbitrum, while leaving many operating details unresolved. The launch dataset marked the venue inactive, and no resumption should be inferred from an accessible domain. The retained research status reads "inactive or inaccessible": The official domain returns only a bare 'Bluff' page; no functioning market, documentation, or legal material could be verified.

The authoritative next step is https://callmybluff.io/. Check that Bluff's branding, legal entity, documentation, and support channels agree before treating the domain as operational. Source confidence is low, so this page describes the evidence without claiming independent operational verification.

The comparison boundary for Bluff is explicit: binary describes listed formats, amm describes the mechanism field, and Arbitrum describes network context. Other product attributes remain open questions. Unverified details remain questions for the cited source, not blanks for inference.

Public source material supplies some access detail for Bluff; those rules can vary by product and can change after this review date. Research summary: The research did not support a complete access-region statement; confirm residency, age, sanctions, and product restrictions.

Treat "inactive" as historical classification for Bluff. Review the latest terms, prohibited jurisdictions, and onboarding screens before assuming access. KYC summary: Identity-verification requirements remain unknown and should be checked during the official account-opening process.

Bluff's structured mechanism field reads amm; its outcome field reads binary. Readers should not infer settlement authority, liquidity, or matching behavior beyond those literal labels.

Bluff should be evaluated market by market. Verify settlement criteria and execution behavior rather than assuming conventions transfer from another prediction venue. Settlement and resolution summary: Acceptable sources did not establish the full resolution path; confirm invalid-market treatment and dispute escalation.

Bluff publishes or documents some economic terms; they should be rechecked in the interface because schedules and market-level parameters can change. Retained fee evidence: The applicable fee structure remains unknown; verify trading, spread, network, deposit, and withdrawal costs.

Bluff has a researched money-flow description, while implementation details and supported onboarding routes may still differ. Retained custody evidence: The custody model remains unresolved; verify whether assets sit with a user wallet, contract, venue, or intermediary.

The main uncertainties around Bluff include price quality, available liquidity, final resolution, custody, security, and jurisdictional change. None is settled by the recorded inactive status. Documented limitations include: No usable product verified., No documentation or legal terms found., and All market mechanics and user protections are unknown..
