The Ethereum Foundation deposited 22,517 ETH — worth roughly $46 million at current prices — into Ethereum's validator contract on March 30, marking its largest-ever single staking move.

On-chain intelligence platform Arkham flagged the transaction, tracing the transfer from a foundation-linked wallet into staking infrastructure. The deposit is the biggest single commit since the foundation announced a new treasury policy in early 2026 to shift from passive holding to active staking.

Part of a Broader 70,000 ETH Plan

The foundation began staking in February with an initial 2,016 ETH deposit, signaling the policy shift. Today's 22,517 ETH transaction accelerates that rollout. The stated goal is to stake up to 70,000 ETH total, with all rewards recycled back into the treasury to fund grants, protocol research, and ecosystem development.

Foundation wallets tracked by Arkham hold approximately $418 million in ETH. About $354 million of that is already staked or earmarked under the new policy.

Why Now

The foundation cites a period of "mild austerity" in its operations — staking turns idle assets into a yield source without requiring ETH sales. It uses open-source validator tools (Dirk and Vouch from Attestant) spread across multiple clients and jurisdictions to avoid centralizing staking power with any single provider.

The deposit lands as Ethereum crosses a milestone: more than half of all circulating ETH supply is now locked in staking for the first time. Total staked ETH stands at over 38 million, spread across approximately 1.17 million validators.
