If crypto was stolen from your Coinbase account, evidence matters.
A Coinbase fraud case often depends on showing what happened, when it happened, and why the transaction was not authorized.
Many people make the mistake of only saying, “My crypto was stolen.” That may be true, but to evaluate a case, you need more detail. The stronger your records are, the easier it may be to show that your account was hacked, your phone was SIM swapped, your email was compromised, or your linked bank account was used without permission.
At Debit Card Lawyer, we help consumers with unauthorized transactions, denied fraud claims, and financial institutions that fail to properly respond when money is stolen. We are reviewing Coinbase fraud cases involving hacked accounts, unauthorized crypto transfers, SIM swaps, phishing, stolen cryptocurrency, and denied fraud claims.

Why Evidence Matters in Coinbase Fraud Cases
Crypto fraud cases can be complicated because cryptocurrency transfers are often difficult or impossible to reverse once completed.
That means the case may not be about simply “undoing” the transaction.
Instead, the case may involve questions like:
- how did someone access the Coinbase account?
- was the transaction authorized?
- did Coinbase detect suspicious activity?
- did Coinbase respond quickly enough?
- did Coinbase properly investigate the fraud report?
- was a linked bank account or debit card used?
- did Coinbase deny the claim without a meaningful explanation?
Those questions require evidence.
The more proof you have, the easier it is to evaluate whether you may have a claim.
Evidence Category 1: Coinbase Transaction Records
Start with the Coinbase records themselves.
Save anything showing:
- the date and time of the transfer
- the amount of crypto transferred
- the type of cryptocurrency involved
- the destination wallet address
- the transaction ID or hash
- whether crypto was converted before transfer
- whether the transfer went to a wallet you do not recognize
- whether the transfer was unusual compared to your normal activity
If possible, download your transaction history from Coinbase and take screenshots.
Do not assume you will always have access to the account later.
Evidence Category 2: Coinbase Security Alerts
Security alerts can be extremely important.
Save any Coinbase emails or messages showing:
- new login alerts
- password changes
- email address changes
- phone number changes
- two-factor authentication changes
- new device approvals
- failed login attempts
- account lock notices
- withdrawal confirmations
- security delay notices
- account recovery messages
These records can help show whether someone accessed your account without permission.
They can also help create a timeline.
Evidence Category 3: Coinbase Support Messages
If you contacted Coinbase, save every message.
This includes:
- support tickets
- emails
- chat messages
- automated responses
- claim denials
- requests for more information
- appeal responses
- account restriction notices
Coinbase’s response may matter.
For example, if you reported the fraud quickly but Coinbase delayed action, that may be important. If Coinbase denied the claim without addressing key facts, that may also be important.
Save the full message, not just a screenshot of one sentence.
Evidence Category 4: Timeline of Events
A clear timeline can make the case much easier to understand.
Write down:
- when you last accessed your Coinbase account normally
- when you first noticed something was wrong
- when you lost phone service, if applicable
- when you received suspicious emails or texts
- when the unauthorized login happened
- when the crypto was transferred
- when you contacted Coinbase
- when Coinbase responded
- when Coinbase denied the claim
- when you contacted your bank, phone carrier, police, or other agencies
Do this while the facts are still fresh.
Even a simple timeline can be very helpful.
Evidence Category 5: Phone Carrier Records for SIM Swap Cases
If your phone was SIM swapped, your phone carrier records may be critical.
A SIM swap happens when someone takes over your phone number by moving it to another SIM card or device. That can allow the fraudster to receive text codes and access accounts.
Ask your phone carrier for records showing:
- when the SIM change happened
- who requested the change
- whether the change happened online, by phone, or in store
- what device or SIM received your number
- when your number was restored
- whether there were failed login attempts
- whether your account PIN or password was bypassed
- whether the carrier noted fraud on the account
Also save screenshots showing “No Service,” “SOS,” or any messages from your carrier.
Evidence Category 6: Email Account Records
Your email account may be the key to the Coinbase hack.
Save records showing:
- password reset emails
- suspicious login alerts
- recovery email changes
- recovery phone changes
- forwarding rules you did not create
- deleted Coinbase emails
- new devices connected to your email
- security alerts from Gmail, Yahoo, Outlook, or another provider
If your email was compromised, the fraudster may have used it to access Coinbase, hide alerts, or reset your password.
That matters.
Evidence Category 7: Bank and Debit Card Records
Some Coinbase fraud cases involve a linked bank account or debit card.
For example, a fraudster may use your bank account to buy crypto on Coinbase and then send the crypto out.
Save:
- bank statements
- debit card transaction records
- ACH transfer records
- Coinbase purchase confirmations
- bank fraud claim submissions
- bank denial letters
- overdraft fees
- insufficient funds fees
- messages with your bank
If your bank account or debit card was used without permission, that may create a separate unauthorized transaction issue.

Evidence Category 8: Police, FTC, and FBI Reports
Reports can help document that you treated the situation as fraud.
Consider saving copies of:
- police report
- FTC IdentityTheft.gov report
- FBI IC3 complaint
- phone carrier fraud report
- bank fraud report
- Coinbase fraud report
These reports may not recover the money by themselves, but they help show that you reported the incident and documented it.
Evidence Category 9: Screenshots of the Fraud
Screenshots can be useful, especially if your account access later changes.
Save screenshots of:
- unauthorized transfers
- unknown wallet addresses
- transaction details
- Coinbase account activity
- Coinbase emails
- text messages
- support chats
- phone carrier alerts
- bank transactions
- error messages
- locked-account notices
Make sure the screenshots show dates, times, and full context whenever possible.
Evidence Category 10: Proof the Activity Was Unusual
One of the most important questions is whether the activity looked suspicious.
Helpful evidence may include:
- you had never sent crypto to that wallet before
- the transfer amount was unusually large
- the transfer happened shortly after a new login
- the transfer happened after a password change
- the transfer happened after a SIM swap
- the transfer happened from a new device
- the transfer happened while you were locked out
- the transfer was inconsistent with your normal account history
These details can help show that the transaction was not normal.
What Not To Do
After Coinbase fraud, avoid these mistakes:
- do not delete emails or text messages
- do not close accounts before saving records
- do not rely only on Coinbase to keep evidence
- do not wait weeks to report the fraud
- do not describe an unauthorized transfer as “I sent crypto” if you did not
- do not ignore your bank if a bank account or debit card was used
- do not assume a Coinbase denial means the case is over
The way you document the fraud can matter.
How to Describe What Happened
When reporting the fraud, be clear.
If someone accessed your account and transferred crypto without permission, say:
My Coinbase account was accessed without my permission, and crypto was transferred out without my authorization.
If your phone was SIM swapped, say:
My phone number was taken over through a SIM swap, and shortly after that, my Coinbase account was accessed and funds were transferred.
If your bank account was used, say:
My linked bank account or debit card was used without my permission to buy crypto.
Clear language helps.
When You Should Contact a Lawyer
You should consider contacting a lawyer if:
- you lost a significant amount of crypto
- Coinbase denied your fraud claim
- Coinbase gave little or no explanation
- your account was accessed without permission
- your phone was SIM swapped
- your email was hacked
- your bank account or debit card was used
- Coinbase support stopped responding
- you are not sure what evidence matters
The sooner you get a legal review, the easier it may be to preserve important records.

Frequently Asked Questions
What evidence do I need for a Coinbase fraud case?
You should save Coinbase transaction records, wallet addresses, transaction IDs, login alerts, security emails, support messages, bank records, phone carrier records, police reports, FTC reports, and FBI IC3 reports.
Should I save the wallet address where my crypto was sent?
Yes. Save the destination wallet address and transaction ID. These details can be important in understanding where the crypto went.
What if Coinbase denied my claim?
Save the denial and all related support messages. A denial does not always mean the case is over.
What if my phone was SIM swapped?
Save phone carrier records, screenshots showing loss of service, carrier messages, Coinbase alerts, and any evidence showing when your phone number was taken over.
What if my email was hacked?
Save email login alerts, password reset messages, recovery-account changes, deleted-message records, and any suspicious forwarding rules.
What if my bank account or debit card was used?
Save bank statements, debit card records, ACH records, bank fraud claim documents, and any denial letters from the bank.
Should I file a police report?
A police report may help document the fraud. You may also consider filing an FTC identity theft report and FBI IC3 complaint.
Can Coinbase still be responsible if the crypto transfer cannot be reversed?
Possibly. Crypto transfers may be irreversible, but the legal issue may involve unauthorized account access, security failures, or how Coinbase handled your fraud report.
