How to Connect Hyperliquid on Scalar Field

Connecting Hyperliquid on Scalar Field gives your agents perpetual futures and spot markets with leverage, shorts, and real funding rates, trading around the clock. It is also the most involved connection on the platform, for one reason worth stating up front: your money ends up living in three places, and only one of them can be withdrawn. That is not a Scalar Field quirk. Hyperliquid is an exchange that holds its own USDC, so funds travel from your wallet, across a bridge, into a perps balance — and spot is a fourth room off to the side. Once you understand the layout, the connection is four clicks and a five-dollar deposit. Once you don’t, you end up staring at a balance you cannot trade with. What you’ll learn:

How the Hyperliquid connection works, and why it needs a bridge
Why you should start with the paper account, which needs none of this
How to open the wallet, fund Arbitrum, deposit to Hyperliquid, and enable trading

How orders, leverage, and shorting behave
How to withdraw, troubleshoot, and disconnect

How the Hyperliquid Connection Works

Three things have to happen before an agent can place an order, and all three are visible as a checklist on the Hyperliquid page. A wallet. Scalar Field creates a self-custodied wallet through Privy with an email login. For Hyperliquid, the relevant chain is Arbitrum, and the same wallet also serves Polymarket on Polygon and Jupiter on Solana. A bridge deposit. Hyperliquid holds USDC on its own exchange, so wallet funds have to cross a bridge — minimum $5, credited to your perps balance in about a minute. A trading key. A one-time approval that lets Scalar Field sign orders for you. The platform describes the boundary precisely: “Funds stay in your wallet; the key can trade but never withdraw.”

Start With Paper, Not This

Hyperliquid has the best paper account on the platform, and it needs no wallet, no bridge, and no deposit. On the portfolio page, the Hyperliquid Paper card — “Practice crypto perps and spot with virtual USDC — live order books, real funding rates, shorts and leverage, no wallet needed” — is one click away via Start Paper Trading.

	Live	Paper
Setup	Wallet, bridge deposit, trading key	One click, provisioned on first use
Funding	USDC bridged from your Arbitrum wallet	$10M virtual USDC, pre-funded in every balance
Transfers between balances	Required	Never needed
Minimum order	$10 notional	None
Margin	Cross or isolated	Cross only
Fills	Real	Simulated against the live order book, with real taker fees

Paper fills are simulated against Hyperliquid’s live L2 order book, and shorts, cross leverage, hourly funding, and liquidations are all modelled. Strategy code that works on HYPERLIQUID_PAPER runs unchanged against HYPERLIQUID. Perps are unforgiving enough that verifying on paper first is the obvious move — connect the live account when a strategy has earned it.

Before You Start

Requirement	Why It Matters
An email address	The only credential; Privy sends a six-digit code to it
At least $5 of USDC, or a card	The bridge rejects less, and buying in-app through MoonPay works too
Native USDC on Arbitrum One	Not Ethereum, not Polygon, and not a bridged variant
About ten minutes	A minute of setup, plus deposit and bridge crediting time

Step 1: Open Your Portfolio

Sign in and go to scalarfield.io/portfolio, then scroll to Connect More, headed “Add exchanges, brokerages, and trading venues.” The Connect More section on the Scalar Field portfolio page

The Connect More section on the Scalar Field portfolio page

Note that there are two Hyperliquid cards: Hyperliquid for live trading, and Hyperliquid Paper for the simulated account.

Step 2: Click Set Up Wallet on the Hyperliquid Card

The Hyperliquid card reads “Trade crypto perpetual futures and spot with leverage, funded by USDC on Arbitrum,” with a Full Trading badge. The Hyperliquid card with its Set Up Wallet button

The Hyperliquid card with its Set Up Wallet button

The button tells you which stage you are at:

What the button says	What it means	Where it takes you
Set Up Wallet, under “Requires wallet setup first”	No wallet yet	The wallet setup flow
Set Up Trading	The wallet exists, but Hyperliquid trading is not enabled	The Hyperliquid page and its setup checklist
The card is gone	Trading is enabled	Look under Your Venues

If yours already reads Set Up Trading, skip to Step 7.

Step 3: Review and Accept the Disclosures

The modal is headed Acknowledgement of terms — “Review the following before activating your trading account.” The Acknowledgement of terms modal as it opens

The Acknowledgement of terms modal as it opens

Seven numbered sections sit in a scrollable panel, with only the first two visible at rest. Section 01 Risk Disclosure covers total loss of deposited funds, and 02 Non-Custodial Nature is the one to read twice: Scalar Field does not hold, control, or custody funds at any time, wallets are self-custodied through Privy, and Scalar Field cannot reverse transactions or recover lost funds. The rest cover third-party services, no financial advice, eligibility, algorithmic trading under SEC and FINRA rules, and a beta disclaimer. Leverage makes that first section less abstract than it sounds. A liquidation on a cross-margin perp position can take the whole balance, and no one can reverse it. Tick both boxes — one for the Terms of Use and Privacy Policy, one for the third-party venue terms — and Acknowledge & continue becomes available. Both consent boxes ticked and the Acknowledge & continue button enabled

Both consent boxes ticked and the Acknowledge & continue button enabled

Step 4: Log In With Email

Setup starts immediately, and a Privy window opens reading Log in or sign up. The Privy log in or sign up window

Enter your email, then the six-digit code Privy sends on the Enter confirmation code screen. The Enter confirmation code screen

No password, no seed phrase — the email is the wallet’s security boundary.

Step 5: Watch the Wallet Get Built

The panel reads Opening wallet mandate — “Your custody wallet, signers, and venue permissions are being configured” — with an Execution Queue progress bar, and rows confirming custody Self-custodied, authentication Email via Privy, and venue coverage Polymarket + Jupiter + Hyperliquid. The Opening wallet mandate screen

It then switches to Activating venues and shows your Polygon custody and Solana custody addresses. The Activating venues screen

Your Arbitrum address is the same address as the Polygon one — both are EVM chains, so one wallet serves both. Nothing Hyperliquid-specific is provisioned in this queue, which is why there is more to do afterwards.

Step 6: Confirm the Wallet Is Live

The panel finishes at Execution wallet live — “Your self-custodied wallet is ready for market access.” The Execution wallet live screen, with Hyperliquid deferred to its own page

The Execution wallet live screen, with Hyperliquid deferred to its own page

Polymarket and Jupiter read Live, but Hyperliquid (Arbitrum) reads Set up from the Hyperliquid page. That is expected: the wallet exists, and Hyperliquid’s own three steps are what remain. Click Done.

Step 7: Open the Hyperliquid Page

Back in Connect More, the Hyperliquid card now reads Set Up Trading. The Hyperliquid card now reading Set Up Trading

Click it, or go to scalarfield.io/portfolio/hyperliquid. You land on Set Up Hyperliquid Trading — “Trade crypto perpetual futures and spot, funded by USDC on Arbitrum” — a three-step checklist that tracks your progress and turns each step green as it completes. The Set Up Hyperliquid Trading checklist with all three steps pending

The Set Up Hyperliquid Trading checklist with all three steps pending

Steps 2 and 3 start unavailable — step 3 says so explicitly with “Available after your first deposit is credited.” Work down the list.

Step 8: Fund Your Arbitrum Wallet

Click Fund Wallet. The modal is headed Fund Your Wallet — “Add USDC to your Arbitrum wallet for Hyperliquid.” The Fund Your Wallet modal in Arbitrum mode

The Fund Your Wallet modal in Arbitrum mode

Buy with a card. Buy USDC opens MoonPay. Funds are deposited on Arbitrum and typically arrive within five minutes. Send crypto directly. Under “Or send crypto directly” is your address, captioned “Send native USDC on Arbitrum One to this address.” The What happens next box in that modal is the clearest summary of the whole model, and it is worth reading before you send anything:

Once the USDC arrives, use Deposit to Hyperliquid on the portfolio page (minimum $5). It is credited to your Perps balance in about a minute.
Your Perps balance trades perpetual futures. To trade spot markets, use To Spot to move USDC into your Spot balance.
Moving funds between Perps and Spot is instant and free.

Send native USDC on Arbitrum One. The wrong network or a bridged variant is not recoverable, and it is the single most expensive mistake available in this flow. Fund a little more than you plan to deposit, since the bridge minimum is $5 and you will want room to move.

Step 9: Deposit to Hyperliquid

With USDC in the wallet, step 1 turns green and step 2 opens up. Enter an amount and click Deposit. The checklist with the deposit step available

The rule to respect: **minimum

5**. Below that, Scalar Field refuses outright with "Minimum deposit is

5 USDC — smaller amounts are lost by the bridge.” That is not a platform policy but a property of the bridge, and the funds do not come back. While the bridge works, the step shows “Waiting for the bridge to credit your deposit”, sometimes with a transaction hash. The deposit waiting for the bridge to credit it

The deposit waiting for the bridge to credit it

It usually takes about a minute. You can close the page — progress is tracked on the portfolio page, and the deposit is polled for several minutes before it gives up and tells you to refresh.

Step 10: Enable Trading

Once the deposit is credited, steps 1 and 2 are green and Enable Trading becomes available. The checklist with the deposit credited and Enable Trading available

The checklist with the deposit credited and Enable Trading available

This is the one-time approval of a Scalar Field trading key for your account: “Funds stay in your wallet; the key can trade but never withdraw.” It is what lets an agent open a position at 4 a.m. without you approving anything, and it is scoped so that the key cannot move your money out. Click Enable Trading. The page becomes your portfolio.

Step 11: Verify Your Hyperliquid Portfolio

The connected Hyperliquid portfolio page showing funds in three places

The header carries a DEX badge, your address — copyable, and linked to Hyperliquid’s explorer — plus Fund, Withdraw, refresh, and Disconnect. Net Portfolio Value is the headline: your Hyperliquid perps account value plus everything in spot, positions included. The smaller cash line below it counts only idle USDC across all three places, which is why the two numbers disagree the moment you hold a position. In the screenshot above, net value is

5.00 while cash reads

6.00, because $1.00 is still sitting in the Arbitrum wallet and has not reached Hyperliquid. Below that sits an Account Value chart with 1D, 1W, 1M, and ALL ranges, then the section that makes this venue click: “Your funds live in 3 places.” The How withdrawals work expander beside it explains each one, and the rest of the page holds:

Place Order, for manual market or limit orders with quantity, limit price, and slippage in basis points
A leverage control, per market
Positions, with market, type, side, size, entry, mark, liquidation price, leverage, value, and P&L
Trade History, including direction and closed P&L per fill
Quick links to the Hyperliquid Explorer and Arbiscan

Where Your Money Lives

Three buckets, and the difference between them is the thing to internalize.

Bucket	What it holds	Can you trade it?	Can you withdraw it?	Getting it out
Arbitrum Wallet	USDC that arrived on Arbitrum but is not yet on Hyperliquid	No	Not directly	Deposit to Hyperliquid, minimum $5
Perps	Your tradable margin balance	Yes, perpetual futures	Yes — this is the only one	Withdraw, flat $1 fee, about five minutes
Spot	USDC and tokens from spot trades	Yes, spot markets	No	To Perps first, then withdraw

Each card states its own status: the Arbitrum wallet says “not yet on Hyperliquid,” perps shows cash alongside margin used, and spot shows cash plus any tokens you hold. Buttons disable themselves when a move is impossible — no Deposit to Hyperliquid below

5, no **Withdraw** unless the perps balance clears the

1 fee. Moving between Perps and Spot in either direction is instant and free, so the only step that costs anything is the final withdrawal. Practically, that means keeping trading capital in perps, moving to spot only when a strategy trades spot markets, and moving it back before you cash out.

How Orders Behave

Perps have more moving parts than any other venue on the platform.

Symbols use an H: prefix. Perps are readable, like H:BTC. Spot uses canonical ids such as H:@142, shown as H:UBTC/USDC — never build a pair name yourself, since major spot assets are Unit-wrapped and H:BTC/USDC does not exist. Discover markets with screenHyperliquidMarkets().
Quantity is in the base asset, not dollars — 0.01 for H:BTC. Size from a budget with round(budget / price, sz_decimals), since quantities that round to zero are rejected.
Selling more than your position opens a short. Perp positions carry signed quantities, and negative means short. There is no separate short call, which is easy to trip over.
Orders below $10 notional are rejected on the live account. The manual order panel shows estimated notional next to that minimum.
Market orders fill synchronously; limit orders rest. A limit order comes back as resting with an order id.
Leverage is a venue setting, per coin — not per order. Changing it “applies to the whole position and every future order on this coin,” and it defaults to cross margin. If a live strategy holds that coin, you have to pause it before changing leverage, because the change re-margins its position.
Funding accrues hourly on perp positions, and can be paid or received.

from scalarlib import screenHyperliquidMarkets, venue

markets = screenHyperliquidMarkets(market_type='perp', query='BTC')
sz_decimals = int(markets.iloc[0]['sz_decimals'])
price = markets.iloc[0]['mark_price']
qty = round(200 / price, sz_decimals)        # ~$200 notional

# Verify on paper, where every balance is pre-funded
venue.trade("buy", "H:BTC", qty, account="HYPERLIQUID_PAPER")

# The same call against the live account
venue.trade("buy", "H:BTC", qty, account="HYPERLIQUID")

How to Withdraw

Click Withdraw. The modal is titled Withdraw to Arbitrum: “Withdrawals are sent from your Perps balance to your Arbitrum wallet,” with a route diagram reading Spot → Perps → Arbitrum Wallet. The Withdraw to Arbitrum modal

It shows your Perps withdrawable balance, an amount field with Max, and the terms: “Flat

1 Hyperliquid fee · arrives in ~5 min." The amount has to exceed

1, since the fee comes out of it, and the modal previews what will actually land in your wallet. If you hold funds in Spot, the modal says so — they cannot be withdrawn directly, and it offers Move Spot to Perps to fix it in one click, instantly and free. Withdrawing lands USDC back in your Arbitrum wallet, which is your own self-custodied wallet. From there you can send it anywhere on Arbitrum, or leave it for a future deposit.

Troubleshooting

What You See	What It Means	What To Do
The card reads Set Up Trading	The wallet exists, but Hyperliquid’s three steps are not done	Open the Hyperliquid page and work down the checklist
Wallet Required on the Hyperliquid page	No wallet yet	Click Set Up Wallet
”Minimum deposit is $5 USDC — smaller amounts are lost by the bridge.”	Below the bridge minimum	Deposit at least $5; do not try a smaller amount
”You only have $X USDC on Arbitrum. Fund the wallet first.”	The deposit exceeds your wallet balance	Fund the wallet, then deposit
Deposit to Hyperliquid is greyed out	The Arbitrum balance is under $5	Add more USDC
”Waiting for the bridge to credit your deposit” for a while	Normal for the first minute or two	Leave it; progress is tracked on the portfolio page
”Taking longer than usual”	The bridge is slow	Use refresh to re-check your balance
Enable Trading is disabled, with “Available after your first deposit is credited.”	The bridge deposit has not landed	Wait for step 2 to turn green
”Failed to enable trading”	The trading-key approval failed	Try again — it is a one-time registration
A deposit never arrives	Likely the wrong network or a bridged USDC variant	Only native USDC on Arbitrum One works
Withdraw is disabled	The perps balance does not clear the $1 fee	Deposit more, or move spot funds to perps
Spot funds cannot be withdrawn	Only perps can be withdrawn	Use Move Spot to Perps, then withdraw
An order is rejected as too small	Under $10 notional on live	Increase the size, or verify on paper first
”Not enough margin for this change.”	The leverage change cannot be margined	Reduce the position, or add margin
”Live strategies hold …”	Agents hold that coin, so leverage is locked	Pause the listed agents, then change leverage
Cannot Disconnect	An agent depends on the connection	Pause or delete the listed agents, then disconnect

How to Disconnect

Click Disconnect on the Hyperliquid page. The Disconnect Wallet confirmation modal

The confirmation reads: “This will remove your wallet connection. Polymarket trading and Hyperliquid credentials from ScalarField will be deleted. Your on-chain funds and positions are not affected.” Two things to be clear about. First, this disconnects the whole wallet, not just Hyperliquid — Polymarket and Jupiter go with it, even though only Polymarket is named. There is no way to detach one venue. Second, your money is untouched. USDC deposited on Hyperliquid stays on Hyperliquid, positions stay open, and the Arbitrum wallet balance stays where it is. Disconnecting removes Scalar Field’s trading key, not your funds — but open perp positions keep running with no agent managing them, so close or hand them off before you disconnect rather than after. If an agent currently depends on the connection, the disconnect is refused with a Cannot Disconnect notice listing the agents by name.

Final Checklist

Before you point an agent at the account, confirm:

Paper first: You have run the strategy on HYPERLIQUID_PAPER, which costs nothing and needs no wallet.
Wallet: Setup finished and you know which email opens it.
Funding: You sent native USDC on Arbitrum One.
Bridge: You deposited at least $5 and it shows in your Perps balance.
Trading key: Enable Trading is done, and the page shows the portfolio rather than the checklist.
Placement: Your capital is in the bucket the strategy trades from — perps for futures, spot for spot markets.
Leverage: Set deliberately, per coin, knowing it defaults to cross margin.
Sizing: You know quantities are in the base asset and live orders need $10 of notional.
Shorts: You know selling more than your position opens a short.
Exit: You know withdrawals come only from perps, cost a flat $1, and that disconnecting leaves positions open.

Final Thoughts

Hyperliquid rewards precision. It is the only venue here where you can be short, levered, and paying funding all at once, and the only one where a bad parameter can liquidate a position rather than merely lose on it. The connection asks for more patience than the others — a wallet, a bridge, a key — but that work is one-time. The judgement is ongoing: how much you bridge across, which bucket it sits in, what leverage you allow, and how small the first live orders are. Use the paper account for everything except the last of those, keep the live balance to what you would accept losing, and let the bridge fee be the most expensive mistake you make here. For order semantics and the research functions available for perps and spot strategies, see the Hyperliquid venue documentation. If several agents will share the account, the agent architecture notes explain how funding and liquidation are attributed between them.
