Arcus Changelog

Web

• Stop orders. The trade form has a new Advanced menu with Stop Market and Stop Limit orders, which are placed once the price reaches the trigger price you set.
• Export Private Key on small screens. If you sign in with email, Google or Apple, the small-screen menu now has Export Private Key, and a standalone Export Private Key page lets you sign in with your Arcus app account to reveal your key.

Web

• Multi-asset collateral for every Perpetuals account. The Margin Account window is now open to every account with Perpetuals access, so you can deposit eligible Stock Tokens and WETH as perp collateral.
• Your wallet now adds and switches to the Arcus network automatically when you connect and before you sign a swap, transfer, or withdrawal.
• Removing margin from an isolated position now lets you withdraw its unrealized gains, down to the position’s initial margin requirement.
• Fixed: the Margin Account now values each Stock Token by the number of shares it represents.
• Fixed: hiding Fills in the chart’s Display menu now keeps fill markers hidden when you zoom, scroll, or change the timeframe.
• Fixed: the Spot chart no longer shows a position line after you sell all of a token.
• Fixed: the Rewards page now lists all of your invite codes, not just the first page.
• Fixed: translating the page with your browser’s built-in translation no longer crashes the app.

Web

• Spot chart remembers your layout. The Spot price chart now keeps your drawings, indicators, and timeframe between visits, saved separately from the Perpetuals chart.
• The trade form now warns when your stop-loss price is at or beyond your estimated liquidation price.
• The take-profit and stop-loss window for an open position now shows the expected PnL at the trigger price you enter.
• Fixed: ETH and WETH in Spot now show ETH’s global market cap.
• Fixed: closing a position at market across several price levels no longer leaves a tiny leftover position.

Web

• Margin tab on the Portfolio page. Accounts with multi-asset collateral access and margin activity now have a Margin tab in the Portfolio page’s Perpetuals tables, next to Transfers.
• Collateral transfers in the margin panel. The margin panel now has a Transfers view listing your collateral deposits and withdrawals with their status, and a rejected deposit offers its refund claim there.
• WETH is now listed in Spot markets, priced and charted with ETH.
• The Settle Loan tab in the Margin Account window now opens even without a loan and shows No outstanding loan.
• Fixed: ETH’s 24-hour change and market stats in Spot now track ETH instead of an unrelated stock that shares its ticker.

Web

• Invite code to trade Perpetuals. To start trading Perpetuals, enter an invite code in the Get access to Perpetuals window. Invite codes come from traders already on Arcus.
• Post Only orders. Limit orders now have a Post Only checkbox that places the order only as a maker order and cancels it if it would fill immediately.
• Favorites saved to your account. Favorite markets are now saved to your account, so they follow you across browsers; connect a wallet to add favorites.
• The VIP card on the Rewards page now shows VIP Status: Unlocked once you reach VIP, instead of disappearing.
• Fixed: the maximum deposit in the Margin Account window now leaves a small buffer under your deposit cap, so a max deposit is no longer rejected when prices move.

Mobile

• Arcus Mobile is live. Arcus Mobile is now on iOS and Android in supported Asia-Pacific regions, with most other regions from January 12, 2027. Trade Stock Tokens, and perpetuals with perps access, from the same account as web.

Web

• Margin Account window (early access). Accounts with multi-asset collateral access can deposit eligible Stock Tokens and WETH as perp collateral, view their loan and loan-to-value, and settle the loan.
• Refunds for rejected deposits. When a deposit is rejected, its notification and transfer progress offer a Claim refund link that returns the funds to your wallet.
• Switching markets now keeps the chart’s zoom level instead of resetting it.
• Fixed: an order popup opened from the chart can no longer place its price on another market after you switch markets.

Web

• The Perps balance in the account menu now shows your total equity instead of your available margin.
• Fixed: the app no longer crashes when your wallet balances fail to load.

Web

• Invite new traders with your referral code. Turn on the new switch on the Invite Codes tab of the Referrals page, and a new trader who joins with your referral code gets one of your unused invite codes automatically.
• Invite codes on the claim page. The Enter Referral or Invite Code step accepts either kind of code and tells you why a code can’t be applied, for example if its owner has no invites left.
• Referral stats can now be switched between all time and the last 30 days, and the referrals table shows each trader’s all-time volume and fees earned.
• Copy All Codes now copies only your unused invite codes.
• The take-profit and stop-loss dialog now shows a short position’s size in red.
• Fixed: enabling trading in a second browser now keeps trading enabled in the first.

• Fixed: after you claim referral fees, your claimable fees update right away.

Mobile (Arcus iOS app — pre-launch)

Mobile (Arcus iOS app — pre-launch)

• Fixed: invite codes can now be entered on the referral code screen.

Web

• Invite codes. The Referrals page now lists the invite codes you’ve earned through trading volume, with each code’s status and when it was used. Copy a single code, or copy every code on the page at once with Copy All Codes. Viewing your codes requires trading to be enabled.
• Your position’s entry line on the chart is now green for a long and red for a short.
• The market selector now opens faster.
• Wallets blocked under the Terms of Use can now withdraw their funds.
• Fixed: after you claim a referral code, the fee discount shown now includes the base discount every referred trader receives, not only the referrer’s extra share.
• Fixed: account equity no longer overstates the value of a short position while that market’s live price is still loading.
• Fixed: on the Referrals page, a long referral link no longer overlaps the code field and its buttons.

Mobile (Arcus iOS app — pre-launch)

• Referral or invite code when joining. The Enter Referral or Invite Code screen accepts either kind of code, and tells you specifically why a code can’t be applied — for example, if it has already been used or is your own.
• Rejected orders now explain more reasons: the order couldn’t be found, you’ve reached the open order limit, or the order expired before it could fill.

Web

• The market ticker in the header can now be scrolled by hand, pauses while you hover over it, and stays still if your system is set to reduce motion.
• Fixed: take-profit and stop-loss orders on markets with tiered price increments are no longer rejected for an off-increment price.
• Fixed: transfers rejected by the exchange now show as Failed in your transfer history, with the reason on hover, instead of Completed.
• Fixed: prices and sizes in your orders, trade history, and funding payments, and in their detail panels, now display at each market’s own precision.
• Fixed: after an app update, reloading now clears a page that failed to load, instead of showing the same error again.
• Fixed: opening the trade page without choosing a market now takes you to perps trading instead of an empty page.

Web

• Order and trade details. Click any row in your orders or trade history to open a side panel with its full details — order type, time in force, reduce-only and margin mode, and for each fill its price, fee, maker or taker role, realized PnL, and whether it opened, added to, closed, or flipped your position.
• Order book hover details and click-to-fill. Hover a price level to see its distance from the mid price, the average price, and the cumulative size in the asset and in USD up to that level. Click a price to set it as your limit price, or click a size or total to fill in your order size. New price levels briefly highlight as they appear.
• Trade history now shows realized PnL on liquidation fills, instead of a dash.
• Mark price now sits with the other market stats in the market header, with a tooltip explaining that it drives margin, unrealized PnL, liquidations, and TP/SL triggers.
• Fixed: market orders on markets with tiered price increments are no longer rejected for an off-increment price.

Mobile (Arcus iOS app — pre-launch)

• Isolated margin. Choose cross or isolated margin for each market from the trade screen, and add or remove margin on an isolated position.
• Clear order results. After you swipe to confirm, the app shows your order executing and then its actual result — placed, filled, partially filled, canceled, or rejected — with the specific reason when an order is rejected, and a warning if an attached take-profit or stop-loss didn’t go through.
• Order and fill detail screens now show a copyable order ID, created and updated times, reduce-only, order value, and whether you were the maker or taker.
• If the app can’t finish loading, or you’re offline, it now shows a clear screen with a Try again button, and a notice tells you when you go offline and when you’re back online.
• Fixed: perps market pages now show the mark price, and the 24-hour change in dollars reads correctly.
• Fixed: the full-screen chart shows the market’s 24-hour change instead of 0.00%, with prices at the market’s precision.

Mobile (Arcus iOS app — pre-launch)

• Edit open orders. Change the price or size of an open order from its detail screen.
• Cancel all open orders. Cancel every open order at once from the Open orders view.
• Order book on market pages. A new Book tab on perps market pages shows bids and asks side by side, with price grouping and USD or asset units.
• Enter a close amount in USD or in the asset, and see your current position size on the close screen.
• The Account screen now shows your total equity, matching the Home screen.
• With no funds available, the trade screens show a Deposit USDG button instead of a disabled order button.
• Fixed: the order book spread percentage now reads correctly.
• Fixed: very large system text sizes no longer break the app’s layout.

Web

• Edit a resting take-profit or stop-loss. Change the trigger price or size (full or partial) of an existing TP/SL order in place — from the orders table, the TP/SL dialog, or by dragging its line on the chart — without cancelling and re-creating it.
• Set a maximum slippage per market. Choose the most slippage you’ll accept for market orders and position closes on a given market, so an order won’t fill beyond the price move you’re willing to take.
• The portfolio header’s change figure now shows your PnL, in dollars and percent, when you’re viewing the PnL breakdown — instead of raw equity change.
• Shared PnL cards now include the trade’s average exit price.
• Fixed: clearer transaction error messages — for example, telling you when you don’t have enough ETH to cover gas.
• Fixed: closing a position now warns you when the close amount exceeds your position size.

Web

• Dashboard fits your window. Resize the browser and the trading dashboard re-fits its panels to fill the available height — and remembers the fitted layout across refreshes.
• Pull to refresh on mobile web. Pull down at the top of the page to reload your data.
• Authorize an API key with just your connected wallet — you no longer need to create a trading key first.

Web

• Close all positions at once. Close every open perp position in a single action — choose which positions to include, and the confirmation lists them in the order they submit.
• Share a PnL card straight from your trade history, now including the trade’s average price.
• Sign in with a social account and your account menu now shows that provider’s icon.
• Disabled buttons now say why an action is unavailable — for example asking you to enable trading or reconnect your wallet — instead of a generic message.

Web

• Isolated margin. Switch a market to isolated margin mode, and add or remove collateral on an isolated position right from the positions panel. An isolated position’s collateral and risk are walled off from the rest of your account, instead of sharing one cross-margin balance across every position.
• Fixed: maintenance margin now calculates correctly.

Web

• The after-hours badge now explains itself with a tooltip — including on touch devices — noting that markets outside regular trading hours require more margin, which reduces your available collateral.
• Liquidation price and account balance now include unpaid funding, so both read more accurately.

Web

• The default perps layout gives the chart more room — the order form column is slimmer at every desktop size.
• Table sort direction is now shown with a single arrow instead of a stacked pair.

Web

• Flex to fit. A new control in the trade header resizes your dashboard so the panels fill the screen exactly, and any panel holding more than it can show now fades at the edge so there is visibly more to scroll.
• The market search box has a clear button.
• Fixed: order book sizes no longer overrun their column — the number of decimals adapts so each size fits.
• Fixed: enabling trading could stall when your wallet needed reconnecting; the prompt now asks you to reconnect first.

Web

• Vaults. A new Vaults section: browse vaults with their performance sparkline and all-time return, open one for its chart, stats, and positions, deposit or withdraw from the vault panel, and track your own performance separately from the vault’s.
• Trade from the price chart. Add a take profit or stop loss by clicking the chart or dragging the line to the price you want, see your liquidation price marked, read unrealized PnL on the position line, and close a position without leaving the chart.
• Full trading history. A dedicated, paginated history page for your complete perps activity, reachable with View all from the portfolio tables — no longer capped at the most recent rows.
• Edit a resting order’s price or size inline from the orders table.
• API keys can be created for a specific subaccount.
• The account summary now shows maintenance margin alongside a corrected margin ratio, and marks when a market is trading after hours.
• Order book grouping is now a dropdown instead of a stepper.
• Your referral is now shown on the position PnL card.
• Fixed: referred volume is now labelled as 30-day.
• Fixed: a spurious logout while the wallet connection was being monitored.
• Fixed: switching tabs on a small screen no longer keeps the previous tab’s scroll position.

Mobile (Arcus iOS app — pre-launch)

• Design polish throughout the app.
• Fixed: a double tap on a navigation control could crash the app.

Web

• Unrecognized WebSocket error codes now show a message with the code instead of failing silently.

Web

• Order book unit selection (USD / asset) now persists across sessions.
• Order-form fee estimates now always apply the correct maker/taker rate for limit orders that cross the book.

Mobile (Arcus iOS app — pre-launch)

• The Arcus iOS app is open for pre-order on the App Store.
• Price charts now display your entry and liquidation prices and mark your past trades directly on the chart.
