Carryfield Open app

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.

Open the app How it works
  • USDC in, USDC out
  • Cancel a queued deposit any time
  • Deposits capped at 50,000 USDC
The Carryfield app: a deposit of 1,000 USDC ready to queue, and the deposit's path: queued, waiting for the keeper to settle after the gate, then claim.

The field

A year of funding, one grain per perp per week

Weekly funding on HIP-3 stock perps, from Hyperliquid's 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.

Funding earned Trading costs Net return

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.

  1. Deposits openYour USDC waits in the vault. Cancel any time, even while paused.
  2. Go/no-go gateLive spot cost at most 0.5% per side for a $15k trade, on three or more stocks.
  3. 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.

  1. 1Queue

    Deposit USDC. It waits until the current epoch settles, and you can take it back until then.

  2. 2Settle

    Once per epoch, every queued deposit settles at one price per share. You claim cfUSDC shares.

  3. 3Leave

    Request a withdrawal. It settles at the next epoch and you claim USDC at that price.

Risks

Before you deposit

Audit status
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.
Full details
The app lists every risk with the live limits from the contract. Read them in the app.

Try it with test USDC.

The vault runs on Elysium testnet. Mint test USDC in the app, queue a deposit, cancel it, and watch how settlement works.
