When German law enforcement seized Hydra's servers in April 2022, the largest Russian-language darknet marketplace ceased to exist. But the vacuum in the market lasted less than a month—a new player, Kraken Market (not to be confused with the exchange of the same name), took the legendary platform's place. My analysis of on-chain data shows that this successor not only filled the vacated niche but also built a complex multi-level money laundering system through which at least $186.5 million passed.

What is Kraken Market

Kraken is a decentralized coordinator platform operating through Tor. Unlike vertically integrated structures, here hundreds of independent shops handle logistics and storage themselves, while the administration provides only the interface, internal BTC balance, and settlement mechanism. This architecture makes the platform nearly indestructible: the arrest of an individual seller does not affect the system's operation as a whole. By 2025, Kraken had achieved a dominant position, and in 2024, approximately $737 million passed through its infrastructure—an amount comparable to the GDP of small nations.

The Path to Dominance

Kraken's history began with aggressive marketing. The project was advertised as Hydra's direct successor, using the WayAway forum to attract sellers from the old ecosystem. In the fall of 2022, the platform even went offline with advertising on a 3D screen in Moscow City and a bus with its logo near the Russian Foreign Ministry building. By the end of December of that year, more than 1,720 shops were registered on the platform, and the hack of competitor Solaris in January 2023 finally cemented Kraken's dominance.

Financial Infrastructure

My research identified three key money laundering routes, each using different blockchain networks to break the link between incoming BTC and final recipients:

• Scheme via BNB Smart Chain ($72.55 million): bitcoins are collected into standard batches of ~10 BTC, held for several days, split into tranches of 1 BTC, and converted into BTCB via the Bridgers service. Then, through PancakeSwap, they are exchanged for USDT/USDC stablecoins, which are distributed across dozens of wallets and ultimately end up on the HTX, MEXC, KuCoin, and Gate.io exchanges.
• Scheme via Avalanche ($74.19 million): the largest route. BTC are split and converted into BTC.b via the Avalanche Bitcoin Bridge, then exchanged for USDT through LFJ and withdrawn to HTX. It is here that a connection to Hydra was found.
• Built-in exchangers ($39.75 million): Kraken's internal services accept BTC from sellers and instantly issue USDT on the TRON network, after which the funds dissolve into a dense network of intermediary wallets.

The Hydra Trail

The key finding is tracing money from the address 3DqTZnes…vHVt, linked to Hydra. Part of the funds that had been sitting there since 2022 began moving in January 2026 and followed exactly the same laundering path as Kraken's funds: the same Avalanche Bitcoin Bridge, the same conversion into BTC.b, the exchange into USDT, and withdrawal to HTX. The coincidence of the entire chain, rather than individual addresses, indicates that one team handled the financial operations of both platforms.

Expert Opinion

The identified $186.5 million is only the lower bound. Private coins and undisclosed clusters remain outside the scope of the analysis. But the main conclusion is not in the numbers but in the structural similarity: Kraken did not simply take Hydra's place—it inherited its financial infrastructure. This means that for law enforcement to effectively combat such platforms, the focus should be not on arresting individual sellers but on blocking precisely the financial nodes—the bridges and exchange services through which all fund flows pass.
