CoinWallet

Coinwalllet, also referenced as CoinWallet, was a Bitcoin trading platform headquartered in France. The service enabled users to exchange Bitcoin for other assets through an online interface. As a digital currency exchange, it targeted retail participants looking for a straightforward method to trade Bitcoin. The platform’s operational model relied on providing a custodial environment where users could hold funds while executing trades. Coinwalllet competed within the nascent cryptocurrency exchange market of the mid‑2010s, a period marked by rapid entrant growth. Public disclosures did not include specifics on user base size, transaction volume, or international footprint. The company’s legal structure, ownership details, or any parent‑subsidiary relationships were not made available in the sources consulted.

On April 6, 2016, Coinwalllet suffered a cyber attack that traced its origin to a vulnerability introduced during a routine service update. The flaw resided in an unfiltered user input field, which allowed attackers to inject malicious code into the system. This code execution led to unauthorized manipulation of the platform’s underlying database. Although the intrusion permitted database tampering, additional security layers prevented the attackers from extracting or transferring customer funds. The breach did, however, expose the encrypted and salted passwords stored for user accounts. In response, Coinwalllet issued a notice urging affected users to change their passwords on any other services where they might have reused the same credentials. The incident undermined trust in the platform’s ability to safeguard user data, prompting the decision to cease operations permanently. Coinwalllet advised users to withdraw any remaining balances immediately following the announcement of the shutdown. This shutdown represented the fourth consecutive closure of a Bitcoin‑focused service caused by a cyber attack within a brief timeframe. Contemporary reports noted that similar disruptions were affecting other cryptocurrency traders, underscoring sector‑wide security challenges. After the cessation of activity, no further public records have emerged regarding Coinwalllet’s eventual fate, assets, or any corporate restructuring.
