Ethereum Foundation Moves 7.79M USDS to Safe Multisig

The Ethereum Foundation transferred 7.79 million USDS to a Safe multisignature wallet in the hour before 10:42 p.m. ET Friday (03:42 UTC Saturday), according to on-chain records, capping a four-day selling program that converted 5,000 ETH into roughly 9.92 million USDS.

The same window included a CoWSwap execution in which the Foundation exchanged 1,000 ETH for approximately $1.9 million in USDS, the Sky-ecosystem stablecoin that has become the Foundation's settlement asset of choice for treasury operations. The latest activity follows an earlier Foundation sale of 2,785 ETH through CoWSwap, which brought in USDS valued at about $6.42 million.

What does the movement change for market participants?

Three operational signals stand out for practitioners tracking Foundation flows.

• Treasury consolidation. Moving 7.79 million USDS into a Safe multisig concentrates liquid stablecoin reserves under multi-key control, the standard institutional posture for custody of operating funds rather than a dispersal to exchanges.

• Execution venue consistency. The Foundation continues to route sales through CoWSwap, the batch-auction protocol that minimizes price impact and does not require the seller to pay gas on individual fills. For a seller of this size, venue selection is a statement about execution discipline.

Pace of conversion. At 5,000 ETH over four days — roughly 1,250 ETH per day, or about 2.3 million USDS of daily conversion at recent prices — the program marks a deliberate acceleration compared with the earlier discrete 2,785 ETH sale worth approximately $6.42 million.

Reading the numbers

The cumulative picture is straightforward. Combined with the prior 2,785 ETH sale, the Foundation has converted at least 7,785 ETH into approximately 16.34 million USDS across the observed transactions. The 1,000 ETH CoWSwap swap that netted about $1.9 million implies an effective price near $1,900 per ETH, a useful reference point for anyone calibrating the Foundation's realized conversion rates.

The choice of USDS rather than USDC or USDT is itself noteworthy. The Foundation has shifted its stablecoin holdings toward the Sky ecosystem token, which ties its treasury operations to a protocol native to Ethereum's own DeFi stack.

Why multisig custody matters here

A Safe multisig requires multiple independent signers to approve any transfer. For an entity that periodically sells ETH to fund grants and operations, this structure reduces single-key risk on liquid reserves. Practitioners monitoring Foundation wallets can treat the Safe address as the primary indicator to watch: inflows signal fresh conversion proceeds awaiting deployment, while outflows typically precede grant disbursements or operational spending.

The transfers also resolve a practical question for on-chain analysts. When sales execute through CoWSwap, proceeds land in seller-controlled addresses that can be difficult to attribute. The consolidation into a known Safe wallet makes subsequent fund flows legible to anyone tracing Foundation treasury activity.

The four-day cadence suggests the program may continue at a similar rate, and observers will be watching whether the Foundation maintains its conversion pace or pauses once stablecoin reserves reach its operating target.
