Sales follow Buterin’s pattern of funding philanthropy and core Ethereum development during market downturns.
Ethereum creator Vitalik Buterin sold more than $30 million worth of ether this month, according to Arkham Intelligence. The sales occurred on-chain throughout January and early February. They aimed to support the Ethereum Foundation during a period Buterin described as “mild austerity,” while also funding his biotech nonprofit.
ETH Sales Reduce Holdings but Fund Core Priorities
Arkham data shows Buterin sold 17,196 ETH this month, worth roughly $35 million. As a result, his ETH holdings declined from over 240,000 at the start of 2026 to about 224,000 ETH. This represents roughly seven percent of his current ETH stack.
Notably, Buterin’s ETH holdings peaked near 663,000 ETH in 2015. Since then, his balance has fallen by more than sixty percent. However, Arkham notes that the reductions align with long-term funding commitments rather than personal spending.
Buterin previously stated the sales reflect his “own share of the austerity.” These comments followed a recent Ethereum price drop below $2,000. The proceeds support Ethereum’s long-term sustainability and core protocol development.
On-Chain Transfers Reveal Destination of Funds
Arkham tracked a major transaction announced by Buterin on January 30. He sold 16,384 ETH, with the movement becoming visible on-chain days later. The transaction originated from a Gnosis Safe Proxy wallet.
Additionally, on February 2, Buterin transferred 211.841 wrapped ETH into CoW Protocol. The trade routed through Wintermute. It resulted in exactly 500,000 USDC sent to Kanro’s wallet. Kanro is a biotech charity founded by Buterin. It funds open-source biomedical research and addresses existential risks, according to public disclosures.
Sales Follow Longstanding Pattern of Donations
Arkham reports that Buterin still holds about $450 million in ETH and AETHWETH. These assets remain split across direct holdings and positions deposited on Aave. Historically, Buterin has linked large token sales to charitable efforts.
In January 2025, he sold meme tokens for $2.5 million, donating the proceeds to Kanro. In 2021, he donated $1.2 billion in SHIB tokens to India’s COVID relief efforts. According to Arkham, the latest ETH sales follow that established pattern.
