Complaint narrative:
XXXX. What Happened On XX/XX/year>, I wired approximately {$40000.00} USD from my bank into my Coinbase account. 
This deposit was successful and appeared in my Coinbase balance. However, without any action, instruction, or authorization from me, XXXX platform automatically used the deposited funds to execute an XXXX XXXX XXXX order. 
I did not open the trading screen, I did not click any buy button, and I did not initiate any trade. 
This transaction was executed entirely without my knowledge or consent. 
When I tried to figure out where my funds had gone, my entire account balance, including {$40000.00}, was stolen in a fraudulent attempt. 
This incident ( {$40000.00} ) was not caused by hacking or unauthorized access by a third party. 
My concern is specifically that XXXX internal systems or automation triggered a trade without my authorization, which constitutes an unauthorized transaction execution. 
________________________________________ XXXX. XXXX XXXX I submitted a formal XXXX XXXX Request to Coinbase, asking for internal logs and records that would explain how this unauthorized trade occurred. 
However, Coinbase has : delayed its response, failed to provide essential data, or provided incomplete or non-substantive answers. 
Coinbase has not provided the necessary information to determine why the trade occurred automatically, nor have they offered any meaningful explanation or resolution. 
The lack of cooperation and transparency prevents me from understanding the cause of the unauthorized transaction and finding my lost funds. 
________________________________________ XXXX. Requested XXXX I respectfully request that the CFPB require Coinbase to provide the following XXXX categories of internal records, which are essential to determining how my funds were used in an unauthorized transaction : XXXX. Transaction Execution Logs Complete logs showing how the XX/XX/XXXX trade was initiated, including order creation method, execution path, order ID, and whether the transaction was manually placed or automatically triggered by XXXX system. 
XXXX. Deposit-to-Trade Linkage Records Internal records showing how my wire deposit of approximately {$40000.00} was processed and how it became connected to the Advanced Trade Buy order that I did not authorize. 
XXXX. System Automation or Trigger Logs Any internal automation logs, system triggers, conditional orders, or automated workflows that could have caused XXXX platform to execute the trade without my action. 
XXXX. XXXX XXXX XXXX, SMS, or push notification logs showing whether Coinbase sent any alerts at the time the unauthorized trade occurred. 
XXXX. Login Activity and XXXX Authentication Logs XXXX  showing IP addresses, device types, login timestamps, and XXXX activity to confirm that no third party accessed my account, reinforcing that this event was caused by XXXX system, not by hacking. 
________________________________________ XXXX XXXX These records are vital for determining how this unauthorized transaction was executed and assessing XXXX compliance with consumer protection obligations. 
I request that the CFPB compel Coinbase to provide complete and unredacted versions of all XXXX categories of documents and require Coinbase to address the loss of my {$40000.00} resulting from this unauthorized transaction. 

Sincerely, XXXX XXXX
