Galaxy Digital has added $100 million of sUSDS, Sky Protocol's yield-bearing savings token, to its corporate treasury and approved it as collateral for institutional clients, the companies said Sept. 23 .

Galaxy and Sky described the treasury position as complete, but their announcement gave no figure for client lending secured by sUSDS or the first completed loan. The decision makes the token eligible across Galaxy's institutional trading business, with actual client uptake still undisclosed.

The attraction is a token that continues to accrue a savings return when pledged. Under the announced arrangement , clients who post sUSDS against a loan keep accruing the Sky Savings Rate on the full position while the loan runs.

Sky says governance sets that rate and funds it from aggregate protocol surplus, and that holders keep the same number of sUSDS tokens as the amount of USDS redeemable for each token increases as it accrues. The savings rate can change, so future accrual is not fixed.

For a borrower, that design could offer access to credit while retaining a savings position. The financial result would depend on the loan terms and the rate available over its life. The announcement does not provide those details for any completed sUSDS-backed borrowing, and it also leaves open how much collateral clients might eventually post.

The companies' relationship already includes credit financing through Grove, a Sky ecosystem agent. In July, Grove announced a $500 million warehouse facility that supplies capital for institutional loans Galaxy originates.

Grove is the warehouse lender, supplying USDS capital, while Galaxy originates and services the loans. Borrower collateral in that facility is limited to Bitcoin and Ethereum, including staked forms of Ethereum.

A Sky Frontier Foundation update published Sept. 17 said Sky agents held about $304 million with Galaxy as of Sept. 1, driven by the Grove facility. That figure describes Sky-side exposure to Galaxy before the new announcement.
