The float
The chain's idle USDG is lent on Morpho on Robinhood Chain under a cap the Safe sets. Every move is an event, and the monthly ledger carries the balance.
BrainChain's idle USDG does not sit still. The Float contract on Robinhood Chain lends it on Morpho, in the largest USDG market there, under a cap the Safe sets: 1,000 USDG for the first month, raised after a clean month.
Who can do what
- The Safe allows markets, sets the cap, funds the float with ETH through the WETH/USDG pool, pauses it, and can take everything back.
- The operator (the brain's desk key) moves USDG between the float and the allowed markets, and releases USDG to the desk when payouts need it.
- USDG can only go to Morpho, to the desk, or back to the Safe. There is no other exit.
The brain keeps a working reserve on the desk, 100 USDG today, and lends what sits above it; when the desk runs short, USDG comes back the same way.

Nothing here is a product anyone deposits into. It is the chain's own money, on the record.
