Bubble Maps is a Web3 data visualization tool that transforms complex on-chain information into intuitive, interactive charts. Each bubble represents a wallet — the larger the bubble, the more tokens it holds — and lines between bubbles indicate token transfers, revealing relationships between addresses. With its color-coded, visual format, Bubble Maps makes it easy to analyze token distribution, identify wallet clustering, detect centralization, and spot suspicious patterns like wash trading, all at a glance.⭐ Why Use Bubble Maps?Bubble Maps makes blockchain data visual and simple. It allows you to:Understand token distribution in secondsIdentify suspicious activity, like wash trading or token hoardingDetect wallet clusters that might be controlled by a single partyDo your own research (DYOR) before investing in a project📘 How to Read a Bubble MapTo make the most of BubbleMaps, here are the key elements you should understand:Bubbles = WalletsEach bubble represents a wallet holding the tokens. The larger the bubble, the more tokens that wallet holds. Most maps display the top 100 holders.Lines = Wallet InteractionsLines between bubbles show actual on-chain transfers. If two bubbles are connected, it means the wallets have exchanged tokens. This helps identify whether wallets are likely linked.Colors = RelationshipsBubbles with the same color are part of the same transfer cluster — they’ve interacted or transferred tokens among themselves. This helps reveal potentially linked wallets or suspicious behavior.Distribution MattersHealthy projects tend to have decentralized holder structures. If most tokens are held by a few addresses or a connected cluster, it may indicate centralized control or dumping risk.🚩 What to Watch ForLarge connected clusters → May indicate insider wallets or whale controlA single wallet with over 50% of supply → Centralization riskFake distribution → Airdrop tokens sent to inactive wallets to fake decentralizationUnconnected top wallets → Often a sign of healthy distribution🌐 Bubble Maps = Visual On-Chain IntelligenceWhether you’re an investor, researcher, or community member, Bubble Maps is a fast and effective way to uncover insights from token data. It bridges the gap between raw blockchain info and meaningful interpretation.📱 How to View Bubble Maps on MoonX1. Click on the MoonX tab in the top navigation bar to enter the page2. Select the token you want to analyze3. Scroll down and click on "Holders" 4. Then you can access the "Bubble Maps" on the right side

MEV (Maximal Extractable Value)MEV (Maximal Extractable Value) refers to the additional value that miners or validators can obtain by reordering transactions. Sandwich attacks are a typical application of MEV, where attackers profit by manipulating the order of transactions.What is a Sandwich Attack?A sandwich attack is a Defi market manipulation strategy where attackers exploit the transparency and controllable transaction ordering of blockchains by inserting transactions before and after a victim's transaction to influence market prices and profit from the price movement.Attack ProcessFront-running Transaction: Attackers observe pending transactions, and if they discover someone attempting to buy a specific token, they will purchase it first, paying higher Gas fees to ensure miners prioritize their transaction.Victim's Transaction Execution: Due to the attacker's buying activity, the price increases, causing the victim to purchase tokens at a higher price.Back-running Transaction: The attacker immediately sells after the victim's transaction completes, profiting from the price fluctuation.Why Do Sandwich Attacks Occur?Blockchain Transaction Transparency: All transactions are publicly visible before confirmation, allowing attackers to monitor the Mempool to predict market movements.Manipulable Transaction Ordering: Attackers can pay higher Gas fees to prioritize their transactions.Automated Bots: Attackers use high-frequency trading bots to automatically monitor and execute these transactions at extremely fast speeds, making it difficult for ordinary users to compete.How to Prevent Sandwich Attacks? Enable Anti-MEV Mode: Turn on the Anti-MEV mode in BYDFi MoonX trading settings.Set Slippage Tolerance: Reduce the acceptable price change range to avoid being attacked.Batch Transactions: Break large transactions into smaller ones to reduce attractiveness to attackers.Why Doesn’t Low Slippage Prevent Sandwich Attacks?Slippage Limit ≠ Protection: If attackers keep price changes within your slippage, the sandwich attack still works.Cannot Prevent Front / Back-Running: Low slippage can’t block order manipulation—attackers use gas to front-/back-run trades.Low Slippage Can Cause Failures: Setting slippage too low can cause failed trades and wasted gas due to volatility or low liquidity.Example: Original price: $0.01 User slippage set to 20% → Acceptable range: $0.008 ~ $0.012 Attacker front-runs, pushes price to $0.015 Node reads updated expected price: $0.015 New slippage range becomes: $0.012 ~ $0.018 If final price is within this range, your transaction still executes Conclusion: Even with a low slippage setting, sandwich attackers can exploit the system by manipulating prices just enough to fall within your acceptable range — effectively “harvesting” your trade.

When trading BYDFi perpetual contracts, traders pay different fees depending on whether their order is classified as a Maker or a Taker.Understanding the difference is important because it affects both your trading costs and your strategy.Maker vs Taker: The Key DifferenceMaker = Adds liquidity to the market.Taker = Removes liquidity from the market.Liquidity simply means how much buying and selling activity exists in the order book. Makers help create market depth, while Takers use (or "take") that liquidity.What Is a Maker?A Maker order is a limit order that is not executed immediately.By placing such an order, you are "making" liquidity in the market because your order sits in the order book, waiting for someone else to match it.Maker orders are typically more cost-efficient for traders who are patient.Example:BTC price is 140,000 USDT.You place a Limit Buy Order at 138,800 USDT.Since it is below the current market price, your order goes into the order book and waits for a seller.This makes you a Maker.👉 Maker Fee Rate on BYDFi: 0.02%What Is a Taker?A Taker order is one that gets matched and executed immediately.This includes market orders and limit orders that instantly match with an existing order in the order book.Takers "take away" liquidity because they remove available orders.Example:BTC price is 140,000 USDT.You place a Market Buy Order.Your order is instantly filled at the best available price in the order book (e.g., 140,000.5 USDT).This makes you a Taker.👉 Taker Fee Rate on BYDFi: 0.06%Maker vs Taker Fee Rates on BYDFiRoleOrder TypeActionFee RateMakerLimit order (not filled immediately)Adds liquidity0.02%TakerMarket order or limit order (immediately filled)Removes liquidity0.06%Why Does It Matter?Makers generally pay lower fees (0.02%) because they provide liquidity and help the exchange run smoothly.Takers pay higher fees (0.06%) because they demand instant execution, removing liquidity.Traders who want to save on fees often prefer Maker strategies (placing patient limit orders).Traders who prioritize speed and certainty often use Taker strategies (market orders).Related ResourcesFor more details, you can also check:Transaction Fee CalculationFunding Fee CalculationWhen Will the Transaction Fees Be Charged?
