Three things you need
An EVM wallet. MetaMask, Rabby or OKX. It signs one approval message. Your private key is never requested.
A Hyperliquid account with USDC. Entropy runs on Hyperliquid rails. A brand-new wallet gets its account created by the first deposit.
Funds on the Entropy balance. $40–50
is enough to start; just size the clip to match in step 3. With $120+ the default clip works untouched.
Move USDC to the Entropy account
Hyperliquid keeps three separate balances: Spot, Perps and the Entropy pocket. Only the last one trades ANTH, and money never moves there on its own — until it does, your Vesper balance reads $0.00 and no orders are placed.
The catch: the Entropy pocket stays hidden in the transfer list until you open its market once. That is the step almost everyone misses, so follow this order on Hyperliquid.
1. Portfolio → Transfer — move your USDC Perps → Spot.
2. Trade — open the Anthropic (IO) market once. The Entropy pocket now appears as a transfer route.
3. Portfolio → Transfer — pick the route named Spot <> Perps (IO) and send the USDC back. It lands in the Entropy pocket, and your Vesper balance stops reading zero.
Want to support the project? Open Entropy through
entropy.io/?r=vesper or add the
code vesper under Referrals. Optional, and it costs you nothing.
One signature, no keys to copy
Open sypherscore.com/vesper/connect, switch the venue to Entropy and connect your wallet. Sign the single ApproveAgent message. That mints a trading key that can place orders and nothing else.

The connect page with Entropy selected. One signature mints the trade-only key.
If the wallet signs but the venue refuses: Hyperliquid allows at most 3 named agents per wallet. Revoke one you no longer use at app.hyperliquid.xyz under More → API, then retry in a fresh tab. A wallet that has never deposited to Hyperliquid needs a deposit first.
Match the clip to your balance
The clip is dollars per order. At 3× leverage a $350 clip needs
about $117 of margin, and if your Entropy balance is below that the venue
quietly rejects every quote. A simple rule: keep the clip at your balance × 2 or less.
With $50 on the account, set the clip to $100 or lower in settings.

Margin and clip live in Strategy & risk. Keep the clip at balance × 2 or less.
Press Start and close the tab
Press Start. Vesper quotes both sides of ANTH within seconds and runs server-side, so the tab can be closed freely. The dashboard shows every fill as it happens.

The dashboard between sessions: equity, the live pulse and the Start button.
Reading the dashboard
- Live status
Making markets, holding, or flattening, as it happens.
- Margin breathes
Entropy shows the margin currently in use, so the figure can read $0 between fills while everything is fine. Your funds sit on the account either way.
- Totals
Volume, fills, fees and CPM: the session's cost per $1M of volume made.
- Stop
Cancels orders, closes the position, halts the session. Wallet-signed; only you can trigger it.
What the key can never do
Withdraw. The agent key places orders only. Funds stay on Hyperliquid in your account and move only by your wallet's signature.
See your wallet key. Only signed messages, ever.
Outlive your consent. Disconnect deletes the key on our side any time, and Stop is wallet-authenticated and global.
