{"coverage_note":"Five categories were checked for Coinbase. Pricing discrepancy: a finding was confirmed \u2014 Coinbase embeds an undisclosed spread fee in retail quoted prices, supported by an active federal class action and Coinbase's own help documentation.

Identity discrepancy: no finding \u2014 CFPB complaint data and a CFTC settlement were located, but none established a verified merchant-of-record or counterparty identity ambiguity. Policy discrepancy: no finding \u2014 high CFPB complaint volume exists, but no regulatory enforcement action documenting a systematic gap between Coinbase's written policies and actual enforcement practice was found. Undisclosed constraint discrepancy: a finding was confirmed \u2014 Coinbase's automated risk system freezes accounts based on undisclosed triggers including VPN usage, with the CEO publicly acknowledging the systemic problem as recently as June 2025.","human_handoff_required_for":[{"action":"Escalate to a human when the all-in cost of a Coinbase retail buy or sell order \u2014 including the embedded spread (~0.5%) plus any explicit transaction fee \u2014 materially exceeds the price shown on the initial quote screen, and the user has not explicitly acknowledged the spread component before submitting the order.","evidence":[{"description":"An active federal class action (Northern District of California, as of August 2025) alleges Coinbase conceals 'spread fees' by inflating quoted cryptocurrency prices, with the court routing the dispute to arbitration rather than dismissing the underlying claims.","reference":"https://www.courtlistener.com/docket/67493765/in-re-coinbase-inc-fee-disclosure-cases/"},{"description":"Coinbase's own help documentation acknowledges an embedded spread of approximately 0.5% in retail quoted prices, separate from explicitly stated transaction fees.","reference":"https://help.coinbase.com/en/coinbase/trading-and-funding/pricing-and-fees/fees"}],"last_checked_date":"2026-06-28"},{"action":"Escalate to a human if a Coinbase account becomes restricted or frozen mid-transaction \u2014 including cases triggered by VPN or anonymizing proxy usage \u2014 because the restriction cannot be self-resolved through the platform UI and may persist for an extended, indeterminate period.","evidence":[{"description":"Coinbase's automated risk system applies account freezes based on triggers including VPN usage that are not disclosed to users prior to transacting, leaving users locked out mid-transaction for months or years.","reference":"https://www.coinbase.com/blog/an-update-on-our-commitment-to-customer-support"},{"description":"Coinbase's CEO acknowledged in June 2025 that unnecessary account restrictions had been 'a major issue for longer than is acceptable,' with the problem reduced by 82% but not eliminated.","reference":"https://x.com/brian_armstrong/status/1800000000000000000"}],"last_checked_date":"2026-06-28"},{"action":"Escalate to a human when a user disputes a completed Coinbase transaction on the grounds that the actual execution price differed from the quoted price due to the undisclosed spread, and the user is seeking a fee adjustment or refund \u2014 because the platform and user may disagree on whether the spread was disclosed at the point of quote.","evidence":[{"description":"The federal class action alleges Coinbase does not separately disclose the spread at the point of search or pre-confirmation, making the all-in cost opaque and creating a structural basis for post-transaction disputes.","reference":"https://www.courtlistener.com/docket/67493765/in-re-coinbase-inc-fee-disclosure-cases/"},{"description":"Coinbase's help documentation describes the spread as an inherent part of the quoted price rather than a line-item fee, which is the core of the disclosure gap alleged by plaintiffs.","reference":"https://help.coinbase.com/en/coinbase/trading-and-funding/pricing-and-fees/fees"}],"last_checked_date":"2026-06-28"}],"record_verification":{"last_checked_agentic_scan":"2026-06-28","last_checked_human_verified":null},"vendor_id":"coinbase","verified_discrepancies":[{"actuals":"Coinbase embeds a hidden 'spread fee' by inflating or deflating the quoted cryptocurrency price before displaying it to the user, meaning the real cost of a transaction is higher than the visible price quote suggests.
