## What happened

Spark governance received a proposal to refill the sUSDS held by the Arbitrum PSM3.

## What changed

The proposal would move a fixed amount across chains from the treasury through an admin call.

## What did not change

The proposal has not been approved or executed, and the funds have not arrived on Arbitrum. It adds no new controller code.

## Confirmed

- The proposal moves 100 million sUSDS from the Ethereum ALM Proxy to the Arbitrum ALM Proxy.
- The payload would grant and revoke CONTROLLER within the same call.
- The proposed transfer has no ALM controller rate limit.

## Still open

- We do not know the vote result, executive authorization, payload execution or redemption of the retryable ticket.
- Nobody outside Spark has reproduced the reported balances and estimates of how long the funds will last.

## What it means for an advisor

- Check that the refill executes and how the admin transfer works before relying on Spark's estimate of how long Sky's Arbitrum liquidity will last.
