Let the price move.
Keep the funding.
Carryfield buys tokenized stocks on Elysium and shorts the same stocks on HyperCore, in the same size. The price moves cancel out. What is left is the funding perp traders pay to stay long, and the vault keeps it.
- USDC in, USDC out
- Cancel a queued deposit any time
- Capped at 50,000 USDC while unaudited
The field: one grain per perp per week
Weekly funding on HIP-3 stock perps, from Hyperliquid's own funding history.
How it works
Two legs, one harvest
For every dollar of a stock the vault holds on Elysium, it is short one dollar of the same stock's perp on HyperCore. When the stock rises, the long leg gains what the short leg loses. When it falls, the reverse.
Most of the time, traders who want to stay long on a perp pay funding to the shorts. That payment does not care which way the price went. That is the harvest.

Illustration: $10,000 on each side and funding at 15% a year, over one week. It leaves out trading costs and the small gap between the two prices.

What if trading on Elysium costs more?
The spot side is the unknown, and the gate allows at most 0.5% per side. Pick a cost and see how much of the return survives.

Launch
Day one, on purpose
Spot costs on Elysium can only be measured once xStocks trade there. So the vault opens with the strategy locked: deposits wait as USDC until a live check passes.
- Deposits openYour USDC waits in the vault. Cancel any time, even while paused.
- Go/no-go gateLive spot cost at most 0.5% per side for a $15k trade, on three or more stocks.
- Strategy livePositions change at the weekly decision. Every decision is published in the keeper journal.
If the gate fails, the vault pauses and every deposit can be cancelled in full.
- 1Queue
Deposit USDC. It waits until the current epoch settles, and you can take it back until then.
- 2Settle
Once per epoch, every queued deposit settles at one price per share. You claim cfUSDC shares.
- 3Leave
Request a withdrawal. It settles at the next epoch and you claim USDC at that price.
Risks
Before you deposit
- Unaudited
- Two internal review passes, no third-party audit yet. That is why deposits are capped.
- You trust the keeper
- The keeper reports prices and the HyperCore account value. The vault bounds those reports, but the account key holder can move its margin.
- Restricted jurisdictions
- xStocks are not offered to US persons or residents of other restricted jurisdictions. If that is you, do not deposit.
- Slow exits
- Withdrawals settle once per epoch. A tripped guard holds settlement until it is resolved.
- You can lose money
- Funding can turn negative, the legs can drift apart, and every trade pays costs.
