How to Use Aster DEX (2026): Step-by-Step Tutorial, from Wallet to First Trade

To use Aster DEX, open asterdex.com, click Connect Wallet (or log in with email), click Deposit and send USDT or USDC, then go to Trade → Perp, set a low leverage and place a Market or Limit order with TP/SL. Maker orders cost 0% and market orders 0.04% on crypto pairs. Here are the six steps, then a screenshot and the details for each one.

1. Connect: Open asterdex.com, pick a chain in the dropdown and click Connect Wallet (or Log in with Email), then sign the message.
2. Deposit: Click Deposit, keep Perpetual Account, choose the network and send USDT or USDC.
3. Open Pro: Go to Trade → Perp (Pro mode) and pick a market such as BTCUSDT.
4. Set margin and leverage: Choose Cross or Isolated and lower the leverage to 2–5x.
5. Place the order: Choose Market or Limit, enter the size in USDT, tick TP/SL and submit.
6. Manage and withdraw: Watch the position in Positions, close it, then click Withdraw.

1. Before you start: what you need

• A wallet or an email. Aster supports Rabby, MetaMask, Binance Wallet and any WalletConnect wallet. With email, Aster creates a wallet address for you, but that account can only receive USDT on Arbitrum One only.
• Stablecoins on a supported chain. USDT or USDC on BNB Chain, Arbitrum, Ethereum or Solana are the simplest. Aster also accepts USD1, BNB, ETH, SOL and several Aster tokens as collateral (details in step 2).
• A little gas. To connect on BNB Chain your wallet must hold at least 0.001 BNB; on other chains you need the chain’s gas token for the deposit transaction.
• Where you live. Aster’s Terms and Conditions (February 25, 2026) prohibit use from the United States, Canada, the United Kingdom, China, North Korea, Russia, Ukraine, Cuba, Iran, Venezuela, Syria and sanctioned regions. If you live there, don’t use Aster, and don’t use a VPN to get around it. Lighter excludes the US, Canada and the UK too, while Hyperliquid and edgeX exclude only Ontario in Canada (perp DEX restrictions by country).
• Ten minutes and a small test amount. The whole flow, including a test deposit, usually takes less than a quarter of an hour on a fast chain.

2. Step 1: connect a wallet or log in with email

With a wallet (recommended, you keep control of the keys):

1. Go to asterdex.com. Our link attaches the invite code: the invite screen (“Your Next Trade Starts Here.”, checked October 21, 2026) shows DTLpLc in the invitation-code boxes. Click Get Started, not “Continue without an invite code”, and pick EVM chains or Solana chain in the window that opens.
2. Pick the chain in the dropdown at the top right (it shows the BNB Chain logo by default). On September 27, 2026 it offered BNB Chain, Ethereum, Arbitrum, Robinhood, Arc and Solana.
3. Click Connect Wallet. The Connect with Aster window lists Log in with Email, WalletConnect, Safe Wallet, Binance Wallet and any browser wallet you have installed (MetaMask, Rabby…).
4. Choose your wallet and approve the signature request. This is a message signature, not a token approval, and costs no gas.

With email: choose Log in with Email, enter your address, type the 6-digit code you receive, create a password, and sign the pop-up message. Aster generates a wallet address for your email; fund it only with USDT on Arbitrum One, because Aster does not refund deposits of the wrong asset or on the wrong network. The email route is convenient but less portable: if you later want to use other chains, a wallet is simpler.

3. Step 2: deposit on the right chain

Click Deposit (under the order form, or next to Avbl). The Account window opens with three tabs, Deposit, Withdraw and Transfer:

1. Account: the first field reads Perpetual Account. Keep it for perp trading. Aster also has a spot account (its balance shows as Spot Total Value); if you ever fund the wrong one, move the money with the Transfer tab instead of withdrawing.
2. Network: choose the chain you are sending from.
3. Token and Amount: pick USDT (or another asset) and the amount, then confirm in your wallet. Buy/Deposit with Binance Pay is an alternative if you hold funds on Binance.

Aster’s public deposit API listed these assets for the perpetual account on September 27, 2026:

Aster charges no deposit fee (0 USDT); you pay only the source chain’s gas. Aster Chain validators confirm deposits, which usually arrive in 1–5 minutes, longer from Ethereum, and land in your cross-margin balance. Coming from a centralized exchange? Withdraw USDT to your own wallet on one of these chains first, then deposit. Send a small test amount before a large one. The Aster deposit and withdrawal guide covers every route and what to do if you send the wrong token.

Collateral modes. By default your account is in Single-Asset Mode, where USDT or USD1 margins the matching markets. Multi-Asset Mode (a switch under Deposit / Withdraw / Transfer) lets BTC, ETH, BNB, ASTER and other assets count as margin at a haircut, in cross margin only, and can auto-convert collateral when a balance goes negative. As a beginner, deposit USDT and stay in Single-Asset Mode.

4. Step 3: open Pro (Perp), not Shield or 1001x

Hover over Trade in the top menu. Under Core you see Perp, Spot, Shield and Prediction; under Advanced, Grid, Vaults and OTC Trading. For your first trades click Perp, which Aster calls Pro mode: a normal order book with limit orders, stops and TP/SL.

Shield’s minimum is 20x, so even its lowest setting is aggressive; at 1001x, a 0.1% move against you is the whole margin. The Aster trading pairs page compares the three modes in more detail.

5. Step 4: set margin and leverage, place your first trade

Perp opens on BTCUSDT. The header shows the symbol with its headline leverage (“BTCUSDT 200x”), last price, Mark and Index price, Funding(8h)/Countdown, 24h Volume and Open Interest. Click the symbol to pick another market; tabs include Favorites, Futures, Spot and Prediction, and filters such as Top, New, Meme, AI, Stocks and Commodities.

1. Margin mode. Click Cross. The BTCUSDT Margin mode window offers Cross and Isolated; the switch applies only to that contract. Isolated limits the loss to the margin you assign to the position, which is easier to reason about for a first trade.
2. Leverage. Click 20x (the default). The Adjust leverage window has a slider from 1x to 200x on BTCUSDT; set 2–5x and confirm. The change also applies to open positions and orders on that market.
3. Order type. Market fills now at the best price (taker, 0.04%) and adds a Slippage Tolerance option. Limit rests at your price (maker, 0%, if it does not cross the book). The third tab opens Stop Limit, Stop Market, Trailing Stop, Post Only, TWAP, Scaled Order and Chase Order.
4. Price and size. For a limit order, type the Order price or click BBO for the best bid/offer. Enter Size in USDT (notional, not margin). The minimum order is 5 USDT on every market, but BTCUSDT’s minimum quantity is 0.001 BTC, about $84 at the September 27, 2026 price.
5. TP/SL. Tick TP/SL. Take Profit and Stop Loss each trigger on Mark (the default) or Last price, and you enter them as PnL (USDT), price or ROI.
6. Options. Hidden Order keeps a resting limit order off the public book; Reduce-Only makes sure an order can only shrink a position; GTC / IOC set the time in force.
7. Check, then submit. Read Liq.Price, Margin and Max under the form, then submit the buy (long) or sell (short) order. If your wallet asks for another signature, check that the site is asterdex.com: trading never needs a token “approve”.

Worked example. You deposit $100 and open a $1,000 BTCUSDT long at 10x, Isolated, with a market order. Taker fee: $1,000 × 0.04% = $0.40. A $1,000 position sits in BTC’s second leverage bracket (maintenance margin rate 0.33%, minus a fixed maintenance amount), so maintenance is about 0.23% of notional and the position is liquidated after roughly a 9.8% fall, before fees and funding. At 5x the same $1,000 needs $200 of margin and survives roughly a 19.8% fall. The form’s Liq.Price shows the exact figure; the leverage and margin guide explains the math.

6. Step 5: manage and close the position

Your trade appears in the Positions tab under the chart, next to Open Orders, Predictions, Assets, Grid, Order History, Trade History and Transaction History. From there you can add or remove isolated margin, edit TP/SL, or close at market or with a limit order. Things to watch:

• Funding. BTCUSDT settles funding every 8 hours (cap ±0.3% per interval); many other pairs settle every 4 hours, and some every 1 or 2 hours. The countdown is in the header. Longs pay shorts when the rate is positive.
• Mark price. Liquidations and, by default, TP/SL use the mark price, not the last trade, so a wick on the chart does not always trigger your stop.
• Leverage creep. If the price moves against you, your effective leverage rises. Add margin or cut the position before the liquidation price gets close.

Trailing stops, scaled orders, TWAP and chase orders are explained in the next section.

7. Aster order types: what each one does and what it costs

Aster Pro has more order types than most perp DEXs. Aster charges by fill side, not by order type: a fill that rests first is maker (0%), a fill that takes liquidity is taker (0.04% on General pairs at VIP 1, 0.10% on Group B pairs, 0.0125% on stocks and commodities).

docs.asterdex.com order-type pages and the V3 futures API docs, checked September 25, 2026.

• Trailing stop. You set a callback rate instead of a stop price. For a long the stop stays that percentage below the highest price since you placed it and never moves down; Aster’s example: long from 95,000 with a 2% callback, BTC rises to 100,000, the stop moves to 98,000, and a fall to 98,000 sends a market sell. In the API it is TRAILING_STOP_MARKET with callbackRate 0.1–5 and an optional activationPrice. Pick a callback wider than normal noise (2–3% on BTC, not 0.5%).
• Hidden order. A limit order invisible on the public book for its whole life that still trades against visible orders; the fill becomes a hidden position excluded from public feeds. Unlike an iceberg it shows nothing, and unlike a dark pool it trades against the main book. Aster documents no extra fee for hiding. For whole-account privacy (balances, positions, ZK-encrypted orders, one-time stealth addresses) Aster Chain has a separate Account Privacy setting; deposits and withdrawals still cross public chains, and a hidden position is liquidated at the same price.
• Scaled order. Up to 110 limit sub-orders across a price range, with equal, increasing, decreasing or random (up to 10% variance) sizes. Keep the whole range behind the touch so every sub-order rests as maker, and have margin for the full size before confirming.
• TWAP. Splits a large order into slices over 1 minute to 7 days; up to 30 strategies per account. The account must keep margin for the full size for the whole run (reduce-only TWAPs are exempt), and one failed slice stops the strategy. Execution is best effort.
• Chase order. A post-only limit that re-prices every second to the best bid (buys) or ask (sells), or a fixed gap behind it, until it fills or the market runs past your maximum chase difference; up to 5 per pair, no editing after submission.
• Post only, BBO and time in force. Post only is rejected rather than taking liquidity, which makes it the biggest fee lever on the venue. BBO prices a limit at the best bid/ask (Counterparty 1, Queue 1, down to the fifth level). GTC rests until cancelled, IOC fills what it can now, FOK fills in full or not at all. A market order with a slippage tolerance becomes an IOC limit at best price ± your tolerance.

Rules that reject orders. Every perp has a tick size, a lot size and a 5 USDT minimum notional (market orders use the mark price). On BTCUSDT the lot size binds first (minimum 0.001 BTC); limit prices must sit inside a band around the mark (±2% on BTCUSDT); each symbol allows 200 open orders, at most 10 of them conditional (stop, take-profit, trailing), so a 110-order scaled ladder uses more than half of a pair’s allowance. Bots should load these filters from exchangeInfo rather than hard-code them (Aster API guide).

1001x and Shield are different. 1001x offers only market, limit, take profit and stop loss, and its limit orders are not order-book orders: they trigger on an aggregated mark price and may not fill even when the chart touches your level. Shield Mode has no order book at all: you choose direction, margin and leverage (minimum 20x).

Common mistakes: taking by habit (0.04% against 0% on every entry and exit), exits without Reduce Only (an oversized stop flips the position), last-price stops in a wick (liquidation uses mark price, and the API’s default trigger is last price), stop limits on thin pairs that gap through the limit, and a TWAP without margin headroom.

8. Step 6: withdraw

1. Click Withdraw under the order form. The same Account window opens on the Withdraw tab with Perpetual Account selected.
2. Select the network, token and amount. The window shows your Withdrawable Amount and the Transaction Fee, which is gas for the destination chain, deducted from the withdrawal; Aster’s docs say it can be as low as 1 USDT.
3. Approve in your wallet. Withdrawals are batched and usually take about 30 seconds; Ethereum takes longer.

If losses, funding or fees left a token with a negative balance (possible in Multi-Asset Mode), fix it first: click Withdraw on that token, then Rebalance, or deposit the missing amount. The rebalance shows as “auto-conversion” in your transaction history.

9. What it costs: fees, funding, leverage

Leverage is capped by bracket: on BTCUSDT 200x only up to $400 of notional, then 150x up to $300,000, and lower above that. Most small caps are capped at 5x. The 5% “pay fees in ASTER” discount applies to spot trading only. The full schedule and VIP tiers are in the Aster fee guide.

10. Aster on mobile

Aster’s docs send you to a Download beta link on asterdex.com. The Android app is on Google Play and as an APK. The iPhone app is listed only in some countries’ App Stores (Taiwan, for example); on September 25, 2026 it was not in the US or Japan App Store. In the app you tap Connect wallet, choose a network and a wallet, and approve the connection and the signature, the same flow as on desktop. You can also open asterdex.com in a phone browser or in the browser inside MetaMask or Trust Wallet. The Aster mobile guide walks through the app.

11. Airdrop and points: what is live

Many “how to use Aster” guides are really airdrop guides, so here is where things stand in Aster’s own docs. The ASTER token airdrop claim closed on October 17, 2025; unclaimed tokens went to ecosystem development. Since then Aster has run points programs in stages. The latest one listed on September 27, 2026 is Stage 6, “Aster Convergence”, which scores trading fees and maker liquidity, position size and time, using ASTER/asBNB/USDF as margin, PnL and referrals, and warns that farmed points may be adjusted. Check the Rewards menu or docs.asterdex.com for the current stage before you trade for points. Our Aster points guide explains the scoring.

12. Can you make money on Aster?

You can, but most people who trade leveraged perps lose money, and every related search for “how to use Aster DEX to make money” skips that. What actually helps:

• Pay less. Limit orders cost 0% as maker on Pro, against 0.04% for market orders; over many trades that difference adds up.
• Size so a mistake is survivable. Risk a small, fixed share of your account per trade and always set a stop.
• Low-risk yield is a different product. Aster Earn (asBNB, USDF) and staking carry their own risks; see the Aster staking guide.

None of this is financial advice. Trade only money you can afford to lose.

13. Safety and fake sites

• Use the real URL. Type asterdex.com or use a bookmark; docs are at docs.asterdex.com. Aster’s own airdrop page warns about phishing and says claiming never needs an “approve” transaction. The same goes for logging in, which is a free signature. A site asking you to approve a token to “connect” or “claim” is a scam.
• Watch the name. Aster (token ASTER) is not Astar Network (ASTR). The names are easy to mix up when you search for the site or buy the token, so check the domain and the ticker.
• Know what you are trusting. Aster Chain’s docs say core chain contracts and RPC are not open-sourced “at the moment” and external validators are not supported in Phase 1. Don’t keep more on any exchange than you are actively trading.
• Start small. Send a test deposit, make a small trade, withdraw it, then scale up.
• Always set a stop. Use TP/SL on entry and Reduce-Only for exits.
• Mind the hype modes. 1001x and Shield are built for very high leverage; a tiny move liquidates you.

14. Aster vs Hyperliquid vs Lighter for a first trade

For most first-time perp traders we point to Hyperliquid for depth (code HOLYGRAIL gives 4% off fees on your first $25M; see how to use Hyperliquid). Aster makes sense if you already hold assets on BNB Chain, want its long list of markets or trade mostly with limit orders. The head-to-head is in Aster vs Hyperliquid; all venues are compared in the best DEX guide.

15. FAQ

Disclosure: DTLpLc and HOLYGRAIL are our referral codes; we earn a share of fees paid by referred accounts. DTLpLc never raises your fees and passes 5% of them back to you as a rebate (split set September 29, 2026). Screenshots, UI labels and numbers were checked in Aster’s app (logged out), public API and docs on October 29, 2026; interfaces change. Perpetual futures with leverage can lose more than you expect. Not financial advice.
