BlackWallet

BlackWallet operated as a digital wallet service for the Stellar blockchain, allowing users to store, send, and receive Stellar lumens. The service provided an online interface for managing cryptocurrency holdings and facilitating transactions on the Stellar network. It targeted individuals and possibly businesses seeking a straightforward wallet for lumens, with its headquarters located in Germany. The platform aimed to simplify access to Stellar‑based assets for a global user base.

The incident in January 2018 revealed that the wallet held sufficient assets to attract a theft of over $400,000 worth of Stellar lumens, equivalent to approximately 670,000 lumens. The malicious code was designed to divert deposits exceeding 20 lumens, indicating the service processed transactions of at least that size routinely. These figures indicate the platform processed lumens transfers and held user funds. No explicit user count or revenue figures are disclosed in the available sources.

BlackWallet specialized exclusively in the Stellar lumen ecosystem, unlike multi‑currency wallets that support various tokens. Its design focused on providing a streamlined experience for Stellar transactions. The service’s creator publicly linked the breach to a compromised hosting provider account, highlighting a reliance on third‑party infrastructure for uptime and security. This incident underscored the challenges of securing wallet services that depend on external hosting environments.

No information is available regarding BlackWallet’s ownership structure, parent company, or subsidiary relationships in the provided material. The service appears to have been operated independently by its creator, who responded directly to the breach by contacting the hosting provider. Consequently, any details about corporate affiliations or governance remain undetermined based on the current sources.
