Ethereum co-founder Joseph Lubin calls Ethereum Digital Asset Treasuries “profound innovations,” backs unlevered $ETH treasuries, and commits 30,000 $ETH to rsETH recovery while pitching Ethereum’s quantum-safe roadmap.
Lubin backs $ETH treasury companies and the DAT model
According to a new report from The Block, Lubin used a panel at Consensus 2026 to single out projects like Strategy, SharpLink, and BitMine—public companies that are accumulating $ETH on their balance sheets—as “positive examples” of Ethereum Digital Asset Treasuries (DATs).
He framed these firms as building “long‑term permanent capital” for the Ethereum ecosystem by buying $ETH spot, staking it, and avoiding leverage, thereby operating more like unlevered, perpetual capital pools than speculative trading vehicles.
SharpLink’s own CEO has described the company as a “focused, disciplined DAT,” continually raising equity via at‑the‑market programs to buy $ETH and then staking to compound holdings—an approach Lubin has publicly supported as a shareholder and strategist.
In his Consensus remarks, Lubin reportedly called the DAT construct itself a “profound innovation,” because it creates listed vehicles whose sole mandate is to convert fiat equity capital into staked $ETH, effectively institutionalizing an $ETH‑standard treasury model.
At the same time, he cautioned that “weak assets and copycat DATs” that lack transparent treasuries, take on leverage, or chase non‑$ETH yield could undermine trust and introduce systemic risk, suggesting that not every self‑proclaimed DAT is necessarily aligned with Ethereum’s long‑term interests.

30,000 $ETH for DeFi United and KelpDAO recovery
Lubin also pointed to Consensys’ and his own role in DeFi United, the multi‑protocol coalition formed to recapitalize rsETH after the April KelpDAO exploit.
Aave and DeFi United disclosed in late April that Consensys and Lubin had “joined DeFi United and would provide up to 30,000 $ETH” to support rsETH recovery, alongside contributions from Aave (25,000 $ETH), Mantle, Lido, and other major protocols.
TRM Labs and Chainalysis estimate that the KelpDAO bridge exploit affected roughly 116,500 rsETH—around 18% of its circulating supply—after attackers compromised internal infrastructure and minted unbacked collateral, triggering a broader DeFi credit shock.
By committing such a large $ETH backstop, Lubin framed DeFi United as an example of “multi‑party collaboration” that Ethereum’s culture makes possible: blue‑chip protocols, infra providers, and treasury companies stepping in collectively rather than waiting for courts or regulators to force restitution.

Ethereum’s quantum-safety roadmap vs. Bitcoin’s migration problem
Lubin also addressed long‑term security, noting that Ethereum has “embedded a path to quantum safety” in its scaling and cryptography roadmap, while Bitcoin will have to grapple with more complex property questions as quantum attacks become realistic.
Ethereum.org’s own future‑proofing documents outline a multi‑year plan to transition away from quantum‑vulnerable primitives—like certain elliptic‑curve signatures and KZG commitments—toward quantum‑resistant schemes based on hash functions (e.g., STARK‑style systems) or lattice problems.
The roadmap focuses on opt‑in, phased migration at the execution layer so that users can gradually move funds to quantum‑safe addresses and authentication methods without disruptive chain splits or forced contract upgrades.
By contrast, research comparing Ethereum and Bitcoin on quantum risk argues that while both rely on similar cryptography today, Ethereum’s more flexible scripting and upgrade pathways make it easier to coordinate large‑scale key rotation and protocol changes, whereas Bitcoin’s UTXO model and hard‑fork aversion could complicate migration of legacy, quantum‑vulnerable addresses and dormant coins.
A crypto.news–style analysis of Ethereum’s quantum roadmap concludes that these upgrades aim to “cement Ethereum as the resilient, decentralized base layer for the future,” a framing Lubin echoed at Consensus when contrasting $ETH’s evolution path with Bitcoin’s ossification.
