Who is the "mysterious fund" that has recently caused a wave of ETH whales? Over the past week, Abraxas Capital, a traditional asset management company from London, quietly withdrew more than 270000 ETH (nearly $700 million) from the exchange, quickly becoming a heavyweight institution of market attention in the cryptocurrency market rebound. On chain data shows that Abraxas is heavily investing in the Ethereum liquid token (LST) ecosystem, including AwETH, wstETH, awstETH, weETH, etc. Its total holdings have exceeded $700 million, and it is actively improving fund reuse through DeFi protocols such as Aave and Compound. At present, its total encrypted assets exceed 1.15 billion US dollars, with a stable asset structure and high frequency of portfolio adjustments, making it a representative of the new generation of "specialized whales". However, this institution is not entirely unfamiliar. Heka Funds, a subsidiary of Abraxas, was once one of Tether's largest institutional clients in its early days, receiving over $1.5 billion in USDT support in 2021, providing critical liquidity for Tether's rapid expansion. Its digital asset fund Elysium was established in 2017, initially focusing on Bitcoin arbitrage strategy, and later shifted to stablecoin trading, with a current management scale of over 3 billion US dollars. It is worth noting that although Abraxas is deeply involved in Tether's trading ecosystem, it has also raised doubts from the outside world due to its complex funding path and opaque information disclosure. Analysis suggests that Heka Funds has received Tether transfers through multiple layers of accounts, making it difficult to trace the true beneficiaries and even resulting in subscription amounts far exceeding the net asset value of the fund. Due to the involvement of executives with offshore leaked databases, their transparency and compliance are challenged. Nevertheless, Abraxas is shifting its focus towards the Ethereum DeFi ecosystem, indicating that traditional asset management institutions are deeply involved in the Web3 market with more complex structures and strategies. As the trend towards market financialization accelerates, the on chain behavior of these 'gray whales' may become an important force in future cycles.
