Drones have rapidly emerged as a central tool of modern armed conflict, reshaping how both state and non-state actors project power. While the bulk of drone purchases still traverse traditional financial rails, these procurement networks increasingly intersect with the blockchain. The blockchain’s transparent and immutable nature enables tracing procurement flows and informs understanding of how emerging technologies are reshaping the economics of conflict. Beginning in the early months of Russia’s full-scale invasion of Ukraine in 2022, dozens of pro-Russia volunteer and paramilitary organizations solicited cryptocurrency donations for military equipment.
Together, these groups raised over $8.3 million in cryptoassets, with drones among the explicitly itemized purchases. One solicitation described a campaign targeting enough rubles to purchase a reconnaissance drone, and a separate listing documented UAV components costing about 200,000 rubles (roughly $3,400) alongside radios, medical supplies, and weapon-cleaning kits. The same Russian militia fundraising group posting on social media about the utility of Chinese-made drones can be observed on-chain making purchases from a Hong Kong-based drone manufacturer. Other wallets purchasing drones have upstream exposure to sanctioned Russian exchanges and other Russia-based services.
The liquidity source for a drone purchaser provides insight into whether its end use is intended for licit or illicit purposes. As shown in the chart below, inflows to our sample of drone vendors originate to differing degrees from illicit sources, with the share of total inflows ebbing and flowing over time. In 2024, OFAC designated two Russian UAV developers: OKO Design Bureau and KB Vostok, both of whom solicited cryptocurrency on public channels. KB Vostok designed the Scalpel, a one-way attack UAV with a payload capacity of up to five kilograms, priced at approximately 200,000 rubles ($2,200) per unit. That price point is analytically significant: at $2,200, recurring unit purchases become plausible on-chain.
KB Vostok’s use of stablecoins, rather than Bitcoin, underscores a broader shift toward dollar-denominated illicit finance for procurement. The KB Vostok case is not just instructive for one manufacturer but a template for how drone vendors on-chain can surface broader procurement networks. By analyzing the source of liquidity flowing into a vendor wallet, investigators can form hypotheses about who the buyers are and where they are operating. Funds from Russian-language no-KYC exchanges suggest Russian buyers; funds from Iranian-linked services suggest Iranian buyers. Mapped against known product prices, transaction prices allow investigators to distinguish between a one-time component purchase and a pattern of recurring procurement that may indicate a state-adjacent supply chain. The Reactor graph depicts the flow of funds from wallets at Garantex and other Russia-related SDNs to drone vendors through intermediary wallets.
The most important insight the blockchain offers is not the volume of crypto flowing into drone procurement; those volumes remain modest relative to the overall scale of warfighting. What the blockchain uniquely offers is near-real-time visibility into procurement networks that would otherwise be entirely opaque. Drones are cheap, proliferating, and increasingly central to how states and non-state actors project power. The blockchain is one of the few places where their financing leaves a permanent, actionable trace.
Inflows to a small subset of drone vendors spiked during the 12-day war between Iran and Israel in June 2025, then returned to pre-war levels.
