ETHZilla, an Ether-focused treasury firm, is raising $350 million through convertible bonds to expand its Ethereum investment strategy

The funds will be used to purchase more Ether and invest in ecosystem projects such as layer-2 protocols and tokenized real-world assets

CEO McAndrew Rudisill said ETHZilla’s approach emphasizes deploying Ether into “cash-flowing assets” to generate recurring returns, positioning the business as scalable with strong operating leverage

The move aligns with a broader trend of crypto firms seeking yield beyond simply holding assets, with expectations of renewed decentralized finance activity.

Financials show ETHZilla has already earned 1.5 million tokens from ecosystem involvement, though details were not disclosed. 

Combined with a prior $156.5 million raise, the company’s capital pool could exceed $506 million

If deployed entirely into Ether, it would add about 120,000 ETH to its existing 102,000 ETH holdings, valued at over $428 million

Formerly a Nasdaq-listed biotech firm, ETHZilla rebranded in July and now ranks as the eighth-largest Ether treasury holder

Its stock, once down over 99% in five years, has rebounded 31% this year, showing renewed investor confidence.
