Guide

Part 1: Introduction

I. Purpose and Scope of This Guide

This guide is intended to provide general, educational information to Coinbase customers who are considering bringing individual lawsuits against Coinbase. It is not legal advice and does not create an attorney-client relationship. Rather, it is designed to explain the procedural framework that governs most Coinbase disputes and to identify issues that materially affect a consumer’s ability to present their Coinbase lawsuit fairly.
Coinbase disputes are governed not by ordinary civil procedure, but by private arbitration rules adopted pursuant to a contractual agreement between Coinbase and its customers. These rules impose structural constraints that differ significantly from litigation in state or federal court. Understanding those constraints before initiating a claim is essential.
The authors of the guide are attorneys Marc Fitapelli and Saul Ancona. They are cryptocurrency attorneys who want to make this information available and accessible to victims of cyber crimes through Coinbase.

II. Available Forums for Coinbase Disputes

A. Small Claims Court

In limited circumstances, a Coinbase customer may be able to pursue a claim in small claims court. Eligibility depends on the jurisdiction in which the consumer resides and the amount of damages sought. Monetary limits vary by state and may differ between counties.
Small claims courts are designed to be accessible and informal. Discovery is minimal, evidentiary rules are relaxed, and proceedings are typically expedited. For claims that clearly fall within jurisdictional limits, small claims court may offer an efficient resolution mechanism. However, small claims courts are subject to statutory damage caps, limited remedial authority, and jurisdictional constraints. In some jurisdictions, Coinbase may also still seek to enforce its arbitration agreement.
Coinbase’s Terms of Service allow customers to bring claims in small claims court, as long as the amount at issue falls within the limits set by their local court. If your claim qualifies for small claims court, it is often worth considering that option first.

B. Arbitration Under the AAA Consumer Rules

For most Coinbase customers, arbitration is mandatory and court litigation is contractually barred. Under Coinbase’s Terms of Service, customers agree that disputes must be resolved through binding arbitration, rather than through lawsuits in state or federal court. These arbitrations are administered by the American Arbitration Association (AAA) and governed by the AAA Consumer Arbitration Rules.
Arbitration is a private adjudicatory process, distinct from the judicial system. There is no jury. The exchange of information between the parties (“discovery”) is significantly more limited than in court. The arbitrator exercises broad discretion over procedure, evidence, and scheduling, and there is generally no meaningful right to appeal an adverse decision. Judicial review of arbitration awards is extremely narrow and is limited to exceptional circumstances.
Because arbitration is the default—and in most cases unavoidable—forum for resolving Coinbase disputes, this guide focuses primarily on how consumer arbitration operates under the AAA Consumer Rules, and on how self-represented consumers can navigate that process as effectively and fairly as possible.

III. The Governing Contractual Framework

A. The Binding Effect of the Terms of Service

This provision requires that disputes be resolved through private arbitration rather than court litigation. The enforceability of mandatory arbitration agreements of this kind has been repeatedly challenged in the courts, including before the United States Supreme Court. Over several decades, the Supreme Court has consistently upheld the validity and enforceability of arbitration provisions, including those contained in consumer contracts.
Importantly, these decisions are not “political” and have not turned on narrow or divided reasoning. The Court’s arbitration jurisprudence reflects a stable and well-settled body of law, grounded primarily in the Federal Arbitration Act, under which arbitration agreements are to be enforced according to their terms. As a result, lower courts routinely compel arbitration when a valid arbitration clause exists.
In practical terms, this means that consumers face an extremely high legal barrier to challenging or avoiding a mandatory arbitration provision once it has been agreed to. While challenges are sometimes raised, they are rarely successful. For most consumers, arbitration is not merely a preferred forum—it is the only legally available forum for resolving disputes covered by the agreement.

Coinbase’s Terms of Service contain an express choice-of-law provision selecting California law to govern disputes arising out of or relating to a customer’s account. Choice-of-law provisions of this type are routinely enforced in arbitration and in court, particularly where, as here, the designated jurisdiction bears a substantial relationship to the parties or the transaction. As a result, California substantive law will generally control the interpretation of the agreement and the evaluation of state-law claims asserted against Coinbase in arbitration.
Because California law applies, consumers may assert claims under California’s consumer-protection statutes, where the factual circumstances support them. These may include, among others, California’s Unfair Competition Law (Bus. & Prof. Code § 17200 et seq.), which prohibits unlawful, unfair, or fraudulent business practices, and provides for equitable relief and restitution. Where applicable, consumers who qualify as elders may also have claims under California’s Elder Abuse and Dependent Adult Civil Protection Act, which affords heightened protections and remedies for financial exploitation. The availability and scope of these claims depend on the specific facts of the consumer’s case, but the choice-of-law provision makes California statutory frameworks directly relevant even for consumers who reside outside the state.
In addition to California law, Coinbase disputes may also implicate federal statutory regimes that apply nationwide and are not displaced by state choice-of-law provisions. Chief among these is the Electronic Fund Transfer Act (EFTA), which governs certain unauthorized electronic fund transfers and establishes consumer protections, disclosure obligations, and liability limitations. Federal statutes such as the EFTA operate concurrently with state law and may be asserted in arbitration where the statutory elements are met.
Finally, although California law governs by contract, consumers who reside in other states should also consider whether their home state’s consumer-protection statutes apply to the conduct at issue. Many state consumer statutes apply extraterritorially where in-state residents are harmed, and arbitration does not inherently preclude the assertion of such claims. Whether a non-California state statute applies will depend on the statute’s language and the specific factual nexus to the consumer’s home state. In appropriate cases, asserting claims under both California law and applicable federal or state consumer-protection laws may be consistent with the governing contractual framework.

Establishes the procedural rules applicable to the arbitration.
The incorporation of the AAA Consumer Arbitration Rules establishes the procedural framework governing the arbitration. These rules define the scope of permissible discovery, the manner in which hearings are conducted, and the degree of formality expected in the proceeding. In effect, they set the procedural boundaries within which the dispute will be resolved.
The AAA Consumer Rules were designed primarily for routine, low-dollar consumer disputes, such as billing disagreements or service complaints. They are not tailored to disputes involving cryptocurrency platforms, cybersecurity failures, or complex financial transactions. As a result, the rules provide for limited discovery, relaxed evidentiary standards, and an overall emphasis on informality and efficiency rather than factual development.
In disputes against Coinbase, this structural mismatch matters. Coinbase has access to internal systems, logs, and security data that are not available to consumers. The limited discovery contemplated by the Consumer Rules can therefore operate to Coinbase’s advantage, and Coinbase routinely seeks to rely on the streamlined nature of the rules to resist meaningful disclosure and narrow the scope of the proceeding.
For this reason, consumers should consistently and clearly emphasize that their case is factually and technically complex, involves substantial sums of money, and cannot be fairly resolved without a reasonable opportunity to obtain and present relevant information. While the Consumer Rules prioritize efficiency, they must still be applied in a manner consistent with fundamental fairness and due process, and arbitrators retain discretion to adapt procedures where the circumstances of the dispute so require.

Coinbase’s User Agreement includes provisions that broadly seek to limit or disclaim Coinbase’s liability for customer losses. While such clauses are common in consumer contracts, they are not absolute and do not automatically bar all claims.
Under California law and federal law, contractual liability waivers cannot eliminate responsibility for certain types of misconduct, including gross negligence, willful or reckless conduct, or violations of statutory duties. In addition, contractual disclaimers generally cannot override consumer-protection statutes or waive rights created by law to protect the public. Where a liability waiver conflicts with statutory obligations or public policy, arbitrators may decline to enforce it.
For this reason, consumers should not assume that a blanket liability waiver ends the inquiry. Instead, the waiver should be addressed narrowly and specifically, with attention to the nature of the claims asserted and the legal duties at issue. In arbitration, such provisions are evaluated in context, and their enforceability depends on the facts and the governing law—not on their breadth alone.

IV. The Role of the Arbitrator

A. Scope of Authority

In arbitration, the arbitrator exercises authority comparable to that of a trial judge, but with substantially broader discretion and far less external oversight. The arbitrator controls nearly every aspect of the proceeding, including whether discovery will be permitted at all, what evidence will be admitted, how the hearing will be conducted, and how applicable legal standards will be interpreted and applied. Most critically, the arbitrator determines the ultimate resolution of the dispute.
Unlike judicial proceedings, arbitration offers no meaningful appellate review on the merits. Arbitration awards are rarely vacated, and judicial review is confined to narrow, exceptional circumstances such as fraud or evident partiality. Errors of law or fact, even significant ones, are generally insufficient to overturn an award. As a result, the arbitrator’s decisions are effectively final.
Because the arbitrator serves as both fact-finder and decision-maker, arbitrator selection is one of the most consequential stages of the arbitration process. Unlike judges, arbitrators are not randomly assigned, do not serve for life, and are not subject to the same institutional constraints or appellate supervision. Instead, arbitrators are selected through a party-driven process, in which each side has the opportunity to evaluate and strike proposed candidates.
For consumers, this selection process represents one of the few meaningful procedural safeguards available in arbitration. Consumers who do not understand the importance of arbitrator selection, or who fail to engage in that process deliberately and thoughtfully, may inadvertently relinquish a critical opportunity to protect their interests before the merits of the dispute are ever reached.

V. Arbitrator Selection Under AAA Procedures

A. The List and Strike Process

After Coinbase responds to an arbitration demand, the American Arbitration Association provides the parties with a list of proposed arbitrators. Each party is afforded an opportunity to strike arbitrators from the list and, in some instances, to rank remaining candidates in order of preference. If the parties strike all proposed arbitrators, the AAA will issue a new list and repeat the process.
This selection procedure may occur multiple times. Under California law and established AAA practice, each party effectively possesses veto authority over proposed arbitrators, as no arbitrator will be appointed without surviving the strike process.
Coinbase’s Terms of Service incorporate a specific “rank-and-strike” mechanism to address situations in which the parties cannot agree on an arbitrator. Under this mechanism, AAA circulates a list of qualified arbitrators, and each party is given the opportunity to strike a designated number of candidates and, where applicable, rank the remaining candidates in order of preference. The arbitrator is then selected based on the highest mutually ranked candidate who has not been struck by either party.
The practical effect of this process is that arbitrator appointment is not random. Instead, it is the product of a structured, party-driven selection process. Consumers should understand that this stage of the arbitration is one of the few opportunities to meaningfully influence the fairness of the proceeding. Failing to participate actively in the rank-and-strike process may result in the appointment of an arbitrator whose background or experience is less suited to the nature of the dispute.

B. Evaluating Arbitrator Backgrounds

Arbitrators are required to disclose professional backgrounds, prior engagements, and potential conflicts. These disclosures should be reviewed carefully.
Consumers often consider striking arbitrators whose professional experience includes:
Representation of banks, insurers, or financial institutions
Employment at large national or international law firms
Regular defense of corporate or institutional parties
Predominantly commercial arbitration practices
Prior service as arbitrators in Coinbase matters
These considerations are not accusations of bias. They reflect the reality that professional experience shapes perspective.
Coinbase is a repeat participant in arbitration. Individual consumers are not. Arbitrators who regularly hear cases involving Coinbase may develop familiarity with Coinbase’s litigation posture, counsel, and defenses. From a fairness perspective, consumers may reasonably prefer arbitrators without prior Coinbase exposure. For this reason, you should also striking any arbitrator who has served on a Coinbase case, but will not disclose all prior rulings and orders to you.

VI. Pre-Filing Preparation

A. Factual Organization

Before filing any claim, consumers should take time to assemble and organize a complete factual record relating to their account and the events at issue. This includes gathering all applicable versions of Coinbase’s Terms of Service, detailed transaction histories, account access and login records, screenshots, emails or messages, and all communications with Coinbase’s customer support. Where relevant, consumers should also obtain copies of any law enforcement reports or IC3 (FBI Internet Crime Complaint Center) filings.
This preparation is important because arbitrators do not independently investigate disputes or reconstruct events. Instead, they rely almost entirely on the information presented by the parties. A clear, well-organized record allows the arbitrator to understand what occurred, when it occurred, and why the consumer contends that Coinbase bears responsibility. Presenting facts in a logical, chronological manner not only improves comprehension, but also enhances credibility. In arbitration, clarity and organization often matter as much as the underlying facts themselves.

B. Understanding Minimum Filing Requirements

Part II: Filing Through Final Award

Procedural mechanics, discovery limitations, and hearing practice

I. The Demand for Arbitration

Arbitration is ordinarily initiated by submitting a Consumer Demand for Arbitration through the American Arbitration Association’s online filing portal. This document serves as the formal commencement of the proceeding. At a minimum, the demand must identify the parties to the dispute, describe the nature of the claim, and state the relief being requested. The applicable arbitration agreement—here, Coinbase’s Terms of Service—must also be provided, along with payment of the required consumer filing fee.
Although arbitration does not impose the same formal pleading standards that apply in court litigation, precision and completeness at this stage are still important. The demand for arbitration is often the first substantive description of the dispute that the arbitrator will review, and it may shape how the case is initially understood. A clear and factually grounded statement of what occurred, when it occurred, and why the consumer contends Coinbase is responsible can influence early procedural decisions, including scheduling, discovery scope, and the overall framing of the issues.
Consumers should avoid unnecessary legal jargon, but should strive to be specific. Vague or conclusory descriptions may invite procedural resistance or make it easier for Coinbase to respond with a generalized denial. By contrast, a concise but detailed narrative helps establish the seriousness and complexity of the dispute from the outset.
As part of the demand, consumers may also request that the arbitration hearing be conducted in person and in or near the consumer’s local jurisdiction. Coinbase may object and seek a remote or virtual hearing, often citing efficiency or cost. Such objections are not automatically controlling. The ultimate decision rests with the arbitrator, who has discretion to determine the appropriate hearing format based on the circumstances of the case, including fairness, practicality, and the nature of the evidence to be presented.

II. Coinbase’s Response

Coinbase commonly responds to arbitration demands with a general denial, a form pleading that broadly denies liability without engaging with the specific factual allegations raised by the consumer. This practice is procedurally permissible under arbitration rules and, by itself, does not constitute a determination on the merits of the claim.
That said, consumers are not required to accept a general denial as the final articulation of Coinbase’s position. Where a response provides little or no factual detail, it is appropriate to raise the issue with the arbitrator and request that Coinbase be directed to clarify its defenses. In doing so, consumers may explain that meaningful case management requires the parties—and the arbitrator—to understand the factual basis on which Coinbase contends it is not liable.
Framing this request in terms of fairness, efficiency, and due process is often effective. Consumers may point out that without some disclosure of Coinbase’s factual defenses, it is difficult to prepare for the hearing, narrow the issues, or determine what evidence is truly in dispute. Arbitrators retain discretion to require more detailed disclosures where necessary to ensure a fair and orderly proceeding.

III. The Preliminary Conference

The preliminary conference is a critical early stage of the arbitration process. Its purpose is to establish the procedural roadmap for the case. During this conference, the arbitrator will address key matters such as the overall schedule, deadlines for exchanging information, the scope (if any) of discovery, and the format and logistics of the final hearing. In practical terms, the preliminary conference sets the structure within which the remainder of the arbitration will proceed.
Because arbitration allows the arbitrator broad discretion over procedure, the decisions made at this stage often have a lasting impact on the case. Limits placed on discovery, hearing length, or evidence exchange during the preliminary conference may be difficult to revisit later. For that reason, this conference is not merely administrative; it is often the point at which the practical boundaries of the dispute are defined.
Consumers should approach the preliminary conference with professionalism, focus, and restraint. Arbitrators generally expect clear, concise explanations rather than argument or advocacy-style presentations. It is appropriate to acknowledge that you are self-represented, but the emphasis should remain on explaining the nature of the dispute and the procedural fairness needed to present it adequately. Where the claim involves fraud, account takeover, or other forms of cybercrime, those circumstances should be described in a factual and measured manner, avoiding speculation or conclusory statements. A calm, organized presentation at this stage helps establish credibility and signals that the case warrants careful procedural management.

IV. Discovery Under AAA Consumer Rules

A. Structural Limits on Discovery

Discovery in consumer arbitration is intentionally limited by design. The AAA Consumer Arbitration Rules emphasize efficiency, speed, and cost control, and arbitrators are encouraged to manage cases in a streamlined manner. As a result, arbitrators often default to allowing little or no formal discovery, particularly in cases that resemble routine consumer disputes.
This structural limitation reflects the assumption that most consumer arbitrations involve relatively simple factual issues, modest amounts in controversy, and roughly symmetrical access to relevant information. In such cases, extensive discovery may be unnecessary and inefficient. However, that assumption does not always hold true in disputes involving cryptocurrency platforms, cybersecurity incidents, or complex financial transactions.
In cases against Coinbase, the limitation on discovery can create a significant information asymmetry. Coinbase controls internal systems, transaction monitoring tools, security logs, access records, and investigative data that are not available to consumers. The consumer, by contrast, typically has access only to outward-facing account information and communications. When discovery is sharply curtailed, this imbalance can materially affect the consumer’s ability to understand what occurred and to present a complete case.
Arbitrators vary in how they address this tension. Some adhere strictly to the minimalist default contemplated by the Consumer Rules. Others recognize that, in certain disputes, limited but meaningful discovery is necessary to ensure fundamental fairness. Consumers should be prepared to explain why their case falls into the latter category.

B. Permissible and Reasonable Discovery Requests

Although discovery is limited, it is not categorically prohibited. The AAA Consumer Rules allow arbitrators to authorize discovery where appropriate, and arbitrators retain discretion to permit the exchange of information necessary for a fair hearing.
Consumers should focus on narrowly tailored, targeted requests that are directly tied to the disputed issues. Overbroad or unfocused requests are more likely to be denied. By contrast, requests that seek specific categories of information uniquely within Coinbase’s control are more likely to be viewed as reasonable.
Examples of discovery that may be appropriate, depending on the facts of the case, include:
Examples of discovery that may be appropriate, depending on the facts of the case, include:

Account access and login logs, including dates, times, and methods of access
IP address data associated with disputed transactions or account activity
Security alerts or risk flags generated by Coinbase’s internal systems
Transaction verification or authorization records
Internal notes or records reflecting Coinbase’s investigation of the incident

C. Consumer Disclosure Obligations

Discovery obligations apply to both parties. Consumers are required to disclose all evidence they intend to rely upon in the arbitration. This includes documents, screenshots, emails, text messages, recordings, reports, and any other materials that may be offered as exhibits at the hearing.
Failure to disclose evidence in advance can undermine credibility and may result in the exclusion of that evidence. Arbitrators generally expect transparency and good-faith participation, particularly from self-represented parties. Consumers should err on the side of disclosure and ensure that all materials are organized, clearly labeled, and provided to Coinbase in accordance with the arbitrator’s scheduling order.
Disclosure is not merely a procedural requirement; it is also a strategic consideration. A complete and orderly exchange of evidence helps narrow disputes, clarifies what facts are contested, and reinforces the consumer’s credibility before the arbitrator.

D. Discovery Disputes and Arbitrator Intervention

Discovery disputes are common in consumer arbitration, particularly in cases involving technical or financial complexity. Coinbase may object to requests on grounds of burden, relevance, or the streamlined nature of the Consumer Rules. When such disputes arise, consumers may seek arbitrator intervention.
Requests for intervention should be concise, factual, and narrowly focused. Consumers should describe what was requested, how Coinbase responded, and why the information is necessary for a fair resolution of the case. It is generally effective to frame the issue in terms of procedural fairness and due process, rather than accusation or rhetoric.
Arbitrator responses to discovery disputes vary. Some arbitrators are reluctant to expand discovery beyond minimal bounds. Others are receptive to limited, well-justified requests. Because outcomes are not predictable, persistence matters. Consumers who raise issues respectfully, document their efforts, and continue to engage professionally are better positioned to obtain relief than those who abandon the issue after an initial denial.
Ultimately, discovery in consumer arbitration requires judgment and restraint. While the process does not allow for broad litigation-style discovery, it does permit arbitrators to ensure that neither party is denied a fair opportunity to present its case. Understanding how to request information thoughtfully—and how to escalate disputes appropriately—is an important part of navigating arbitration effectively.

VI. Hearing Preparation

Effective hearing preparation in consumer arbitration places far greater emphasis on organization and clarity than on formal legal argument. Unlike court proceedings, arbitration hearings are typically less structured, and arbitrators rely heavily on the parties’ presentations to understand both the facts and the sequence of events. A well-organized presentation can materially affect how the arbitrator perceives the credibility and seriousness of a case.
Consumers should begin by preparing a clear chronological narrative that explains what occurred from start to finish. This narrative should identify key dates, transactions, communications, and turning points in a logical sequence. Arbitrators are not expected to reconstruct events from scattered documents or testimony; they depend on the parties to present a coherent account that makes the factual issues understandable.
All documents intended for use at the hearing should be clearly labeled and organized as exhibits. Each exhibit should be easy to identify and reference during testimony. Disorganized or unexplained documents can distract from the substance of the claim and make it difficult for the arbitrator to follow the presentation. Organization signals preparation and enhances credibility.
Consumers should also anticipate the questions that may be asked by both the arbitrator and Coinbase’s counsel. Preparing concise, factual responses helps avoid confusion and reduces the risk of inconsistent or speculative testimony. Explanations should be straightforward and grounded in the evidence, rather than argumentative or emotional. Arbitrators generally value coherence, consistency, and factual grounding over legal rhetoric, and effective preparation reflects an understanding of that priority.

VII. The Arbitration Hearing

At the arbitration hearing, both parties are given the opportunity to present testimony and documentary evidence in support of their respective positions. Consumers may testify on their own behalf, respond to questions from the arbitrator and Coinbase’s counsel, and, where applicable, cross-examine Coinbase’s witnesses. Although arbitration hearings are generally less formal than court trials, they remain structured proceedings in which the arbitrator evaluates credibility, consistency, and evidentiary support.
The hearing represents the central evidentiary stage of the arbitration. It is the primary opportunity for the consumer to explain, in a clear and organized manner, what occurred, how the disputed transactions or events unfolded, and why the consumer contends that Coinbase bears responsibility. Arbitrators do not conduct independent investigations and do not rely on filings alone; they assess the case largely based on what is presented at the hearing.
For self-represented consumers, the emphasis should be on clarity and factual explanation, rather than legal argument or advocacy techniques. Calm, direct testimony grounded in the documentary record assists the arbitrator in understanding the dispute and evaluating whether the requested relief is warranted under the applicable law and arbitration rules.

VIII. The Final Award

Following the conclusion of the hearing, the arbitrator will issue a written decision, often referred to as an arbitration award. The timing and level of detail of the decision may vary, but it typically addresses the claims asserted, the evidence presented, and the relief, if any, that is awarded.
Under the AAA Consumer Arbitration Rules, the consumer’s financial responsibility is generally limited to the initial filing fee, which is currently capped at a fixed amount. The remaining administrative fees and the arbitrator’s compensation are borne by Coinbase. This allocation of costs is intended to ensure that consumer access to arbitration is not precluded by prohibitive expenses.
The arbitration award is final and binding on the parties. Unlike court judgments, arbitration awards are not subject to appeal on the merits. Judicial review is extremely limited and confined to narrow statutory grounds, such as fraud or evident partiality. As a result, the arbitrator’s decision ordinarily represents the final resolution of the dispute.
