A Dev Guide to Placing Orders using Hyperliquid API IntroductionHyperliquid is a high-performancedecentralized perpetual exchange offering low-latency trading. For developers building algorithmic strategies, bots, or integrations, Hyperliquid exposes both REST and WebSocket APIs. This guide provides a step-by-step walk-through of how to place a basic order using the REST API in Node.js.This script demonstrates how to place a limit sell order for the HYPE token on the Hyperliquid testnet using JavaScript. It utilizes the ethers library for wallet management and the @nktkas/hyperliquid SDK to interact with Hyperliquid's API.Overview of Hyperliquid's Use CasesHyperliquid offers fast, API-based access to decentralized perpetual trading. Developers commonly use it to:Build bots for placing and managing ordersMonitor positions, funding rates, and liquidationsSimulate and test strategies on the testnetIntegrate trading data into dashboards or analytics toolsTrigger trades based on on-chain or external signalsIts design supports both simple scripts and complex trading systems with low latency.Who Should Use This Guide?This guide is for developers who want to:Place limit orders using Hyperliquid's REST APITest trading logic in a controlled testnet environmentIntegrate order placement into existing apps or botsUnderstand how the Hyperliquid SDK interacts with wallets and marketsIf you're familiar with JavaScript and basic API workflows, you'll find this walkthrough easy to follow.Prerequisites for Integrating Hyperliquid API in Your Crypto Trading SystemNode.js and npmethers and @nktkas/hyperliquid npm packagesHyperliquid API Integration: Setting Up Imports and Configuring Your Environmentimport * as hl from '@nktkas/hyperliquid'; import { ethers } from 'ethers'; const privateKey = 'YOUR_PRIVATE_KEY'; // Set up a connection to the Hyperliquid API (using the testnet environment) const transport = new hl.HttpTransport({ isTestnet: true }); // Initialize a wallet instance using the provided private key to sign transactions const wallet = new ethers.Wallet(privateKey); // Set up the ExchangeClient for placing orders and handling trading operations const exchangeClient = new hl.ExchangeClient({ wallet, transport, isTestnet: true, }); // Set up the InfoClient to retrieve market data and other relevant information const infoClient = new hl.InfoClient({ transport }); Component Explanations:HttpTransport : Establishes a connection to the Hyperliquid API. TheisTestnet flag ensures you're working with the testnet environment.ethers.Wallet : Creates a wallet instance using your private key. This wallet is used for signing transactions.ExchangeClient : Manages order placements and various trading operations.InfoClient : Provides access to market metadata and informational endpoints.Also, Explore |Creating a Custom Hyperliquid Dashboard: Track Live Holdings in ReactPreparing for a Smooth IntegrationChecklist Before You BeginClarify Your Requirements:Define the specific functionality you need from the system or API.Review API Documentation:Understand the endpoints, authentication methods, and rate limits.Set Up Your Development Environment:Ensure dependencies are installed and your environment is ready for integration.Prepare Authentication Credentials:Securely store your API keys or tokens.Use Test Environment:Start integration in a test or staging environment to avoid issues in production.As highlighted in the officialHyperliquid API documentation, integrating with their testnet environment is crucial for ensuring stable deployments. We've followed these guidelines extensively when deploying automated strategies for our clients, ensuring a smooth and risk-free integration before moving to production.Tips for Avoiding Common Setup MistakesTest First:Always validate the integration in a controlled environment before going live.Monitor Rate Limits:Ensure you don't exceed API rate limits by optimizing your calls.Map Data Correctly:Double-check the data formats to avoid integration errors.Secure Sensitive Data:Use environment variables to store API keys, not hardcoded values.Handle Errors Efficiently:Implement error handling and logging to quickly identify and fix issues.Plan for Scalability:Make sure your integration can handle increased traffic as your system grows.Main function:async function main() { try { // Retrieve market metadata for available assets and trading pairs const [meta] = await infoClient.metaAndAssetCtxs(); // Find the index of the 'HYPE' asset within the available assets const assetIndex = meta.universe.findIndex( (asset) => asset.name === 'HYPE' ); // Check if the HYPE asset exists if (assetIndex === -1) { throw new Error('HYPE asset not found.'); } // Define order parameters const orderParams = { orders: [ { a: assetIndex, // Asset index for HYPE b: false, // false for sell, true for buy p: '100', // Limit price (string format) s: '0.1', // Order size (string format) r: false, // No reduce-only flag t: { limit: { tif: 'Gtc', // Time-in-force: 'Good 'til canceled' }, }, }, ], grouping: 'na', // No specific grouping for the order }; // Place the order on the Hyperliquid exchange const response = await exchangeClient.order(orderParams); console.log('Order placed successfully:', response); } catch (error) { // Error handling: Log any issues that occur during the order placement process console.error('Error placing order:', error); console.error( 'Error details:', error.response ? error.response.response.data : error.message ); }}Explanation:Retrieve Market Metadata:The functionmetaAndAssetCtxs() fetches metadata about available trading pairs from the Hyperliquid API.Find Asset Index:The code searches for the index of the 'HYPE' asset in the available assets list. This index is needed to specify the asset when placing an order.Order Parameters:a: Specifies the asset index for 'HYPE'.b: A boolean flag indicating the order side (false for sell,true for buy).p: The limit price, set to100 in this case.s: The order size, set to0.1 HYPE.r: A flag indicating whether the order is reduce-only (set tofalse here).t: Time-in-force setting (Gtc means the order is good until canceled).grouping: Set to'na', meaning no specific grouping for this order.Place Order:The functionexchangeClient.order(orderParams) sends the order to the Hyperliquid exchange, where it gets processed.Error Handling:Any errors encountered during the order process are caught, logged, and detailed error messages are provided for debugging.You may also like |How to Fetch Transaction History on Ethereum using Web3.pyDeveloper Best PracticesKeeping Your Integration SecureUse Secure Authentication:Always implement OAuth, API keys, or other secure authentication methods, and avoid hardcoding credentials in your codebase.Encrypt Sensitive Data:Ensure that sensitive data such as API keys, user details, and transaction information is encrypted both in transit and at rest.Follow Least Privilege Principle:Grant the minimum required permissions for users or services to access the integration.Regularly Rotate Keys and Tokens:Periodically change API keys and authentication tokens to reduce the risk of unauthorized access.Managing API Reliability Over TimeMonitor API Usage and Performance:Track API calls and error rates to identify potential issues before they impact your application.Handle API Downtime Gracefully:Implement retries with exponential backoff and fallback mechanisms to ensure smooth user experience during downtime.Check for Deprecations and Updates:Regularly review API documentation for breaking changes, new features, or deprecations that could affect your integration.Implement Logging and Alerts:Set up logging for all API interactions and create alerts for failures or unexpected behavior.Testing Your Integration Before Going LiveTest in a Sandbox Environment:Use a sandbox or testnet environment to simulate real-world scenarios and detect issues early.Test for Edge Cases:Ensure your integration handles unexpected inputs, errors, and edge cases such as rate limit breaches or invalid data formats.Verify Data Accuracy:Double-check that the data returned by the API is correct, and ensure your application properly handles it.Perform Load Testing:Simulate high traffic to identify performance bottlenecks and optimize your integration for scalability.Important considerations:Account Initialization:Ensure that the wallet address derived from your private key has been initialized on Hyperliquid.Without proper initialization, you may encounter the following error: User or API Wallet does not exist.Collateral Requirements:Collateral is required, even for spot trades.Hyperliquid mandates a minimum amount of USDC collateral in your perpetuals account.For example, to sell 0.1 HYPE at $100, you'll need at least$10 USDC as collateral.Testnet vs. Mainnet:The script is configured fortestnet (isTestnet: true).Ensure that you're interacting with the correct network based on your environment—testnet for testing and mainnet for live transactions.Error Messages:Pay close attention to error messages returned by the API.These messages offer valuable insights into issues such asinsufficient margin orincorrect asset indices.Also, Discover |Stablecoin Development with CDP (Collateralized Debt Positions)Conclusion.This guide outlines a simple and efficient approach for placing limit sell orders on the Hyperliquid testnet using the REST API in Node.js. By utilizing the @nktkas/hyperliquid SDK and ethers.js for wallet management, you can easily integrate order placement into your algorithmic strategies or trading bots.However, it's important to keep in mind a few key considerations:Wallet Initialization: Ensure that your wallet address is properly initialized on Hyperliquid.Collateral Requirements: Make sure you meet the necessary collateral requirements.Network Selection: Double-check that you're interacting with the correct network (testnet vs. mainnet).With this setup, you'll be able to execute trades efficiently, taking full advantage of Hyperliquid's low-latency and high-performance decentralized exchange.By integratingHyperliquid API, we enabled our clients to benefit from low-latency trading and efficient order management.

How to Place a Limit Order on Ethereum using Kyberswap In this guide, we will walk through the process of placing a limit order on Kyberswap using their API. Kyberswap is a decentralized exchange (DEX) aggregator that provides the best token prices by aggregating liquidity from various DEXs. By leveraging Kyberswap's API, we can automate the process of placing limit orders for token trades, giving you full control over your trade price. This tutorial will guide you through setting up the necessary environment, writing the code to interact with the Kyberswap API, and successfully placing a limit order using Node.js and the appropriate dependencies. For more about DEX, visit crypto exchange development services.What is a limit order?A limit order is an instruction to buy or sell your token at a specific price or better. It gives control over the trade price to be executed.For example:A buy limit order will only execute at the limit price. And a sell limit order will only execute at the limit price or higher.What is Kyberswap?A dex aggregator & liquidity protocol that provides the best token price by aggregating liquidity from various DEXs. It also provides liquidity providers with opportunities to earn rewards by depositing their tokens.Before everything, you must have Node.js and VS Code installed.Let's set up this:Open your terminal and type this command: 1. mkdir KyberswapApi 2. cd KyberswapApi 3. code .It will open your project KyberswapApi in VS Code, then open the terminal in VS Code and type this command: npm init It will initialize a project and create the package.json file. npm install viem ethers axios It will install all dependencies in your package.json file.Create a file index.js and paste this ProgramRun this command in your terminal : node index.js (this will create the limit order successfully).Also, Read | A Dev Guide to Placing Orders using Hyperliquid APIHow to use Kyberswap Api to place a limit orderTo create a new order, we need to make a post request on this URL: https://limit-order.kyberswap.com/write/api/v1/ordersFor this, we need params which include the signed EIP712 message and returned data from this post request(https://limit-order.kyberswap.com/write/api/v1/orders/sign-message).Program : import { createWalletClient, erc20Abi, parseEther, getContract, createPublicClient, http, encodeFunctionData } from "viem"; import { ethers } from "ethers"; import axios from "axios"; import { privateKeyToAccount } from 'viem/accounts'; import { base } from 'viem/chains'; const kyberApiUrl = "https://limit-order.kyberswap.com"; const privateKey = "000000X4PRivateKey"; const rpcUrl = "https://mainnet.base.org"; async function mainApprove(makerAsset, limitOrderContract, maker, makingAmount) { const client = createPublicClient({ chain: { id: 8453, // Base chain ID name: "Base", rpcUrls: { default: { http: ["https://mainnet.base.org"] }, }, }, transport: http("https://mainnet.base.org") }); console.log("Client created for Base chain:", client); const tokenContract = getContract({ abi: erc20Abi, address: makerAsset, client: client, }); console.log("here is the tokenContract",tokenContract.address); const currentAllowance = await tokenContract.read.allowance([ maker, limitOrderContract, ]); console.log("Current Allowance:", currentAllowance.toString()); const encodedCalls = []; if (BigInt(currentAllowance) < BigInt('100000000')) { console.log("here it comes "); const approvalData =await getTokenApprovalCalldata( makerAsset, limitOrderContract, makingAmount, ); console.log(' Approval Data:', approvalData); encodedCalls.push({ to: makerAsset , data: approvalData, // gas: '0.007547422' //approvalGas.toString(), }); console.log("Encoded Calls:", encodedCalls); const swaptx = encodedCalls; const str = "000000X4PRivateKey"; const account = privateKeyToAccount(`0x${str}`); const walletClient = createWalletClient({ account, chain: base, transport: http('https://mainnet.base.org'), }); console.log("Wallet Client created:"); const tx1=[]; for (const call of swaptx) { const tx = { to: call.to, data: call.data, value: call.value ?

Because in this rapidly evolving digital landscape, a business cannot afford to keep its PWA unoptimized, as it would lead to:Lose revenue due to slow laggy apps causing abandoned carts and incomplete transactions.Reduced visibility due to f ailing to meet Google's Core Web Vitals criteria for speed and interactivity, resulting in poor SEO performance.Limited reach, as markets with constrained connectivity would remain inaccessible in case the PWA has resource-heavy requirements or lacks offline functionality.Investing in optimizing your PWAs is not just necessary; it is also a strategic move to improve your conversion rates, enhance accessibility, lower maintenance costs, enable seamless functionality, and drive a greater business impact. To help you better understand the optimization techniques for enhancing your PWA, we have provided a detailed discussion of the most effective strategies to elevate its user experience, performance and functionality.Proven Strategies to Maximize Your PWA's Performance and Impact1. Optimize Asset Loading:If you want to ensure that your PWA delivers high performance and a smooth user experience consistently across all platforms and scenarios, it is crucial to streamline your assets, which allows for faster loading and better performance. These assets or resources can be anything from HTML, CSS, Javascript, and images to multimedia files.Poorly managed assets lead to higher data consumption, slower loading times and below-average user experiences. Customers today are spoiled for choice and unoptimized assets on your PWAs can make them immediately switch to other faster options, causing your business to lose precious revenue.One of the major techniques in asset optimization that you can implement is lazy loading, which works by deferring the loading of less essential resources until they are needed. You can commonly see it while scrolling lengthy webpages on sites, where the image and content only appear when you reach that exact location on the webpage.Code Splitting is another important method you can use, which is achieved by splitting large Javascript files into smaller, context-based portions that are only downloaded and executed when that specific code is required for user interaction.Preloading, prefetching and applying minification and compression, are other effective techniques to optimize your PWA assets, Preloading helps with fetching resources deemed necessary early in the page lifecycle. Prefetching attempts to anticipate navigation patterns to load assets for upcoming pages in the background. And to optimize your files, minfication (refers to removing unnecessary spaces and characters from code) and compression using algorithms such as Brotli and Gzip ensure faster transfer for HTML, CSS, and Javascript files.A service worker is a Javascript file that runs in the background, independently from the webpage that functions as a programmable network proxy for intercepting and handling network requests. It is primarily used for enabling caching strategies and resource management that play a major role in improving performance, functionality and user experiences.To utilize your service workers effectively, firstly you need to implement a precaching strategy where it caches crucial assets like HTML, CSS and Javascript files during its installation phase. This proves to be especially useful when the app is launched, as these cached files can be served immediately even without network connectivity. You can use a ‘cache-first' strategy for static files and a “network-first” strategy for content with dynamic nature.Moreover, you can also implement ‘state-while-revalidate” strategies where cached files are served immediately when the latest data is being fetched in the background. Service works are also effective for background synchronization, which enables users' actions to be processed quickly once the device is reconnected to the internet, such as form submissions.And lastly, you can perform periodic monitoring and updates to the service worker script to maximize the performance and user experience of the PWAs. This would ensure minimal disruptions, smooth upgrades, and help it evolve with the app's growing requirements.3. Apply Responsive and Adaptive Design Strategies:Application of responsive and adaptive design strategies can serve an integral role in making sure your your PWA is visually consistent and is effective in providing seamless user experiences, regardless of the user's device or network connectivity.Responsive design allows for dynamic adjustment to any screen without losing on quality. By creating a fluid layout utilizing CSS techniques like media queries, flexible grids and viewport settings, it ensures that PWAs deliver seamless experiences across all platforms, and in all conditions.On the other hand, adaptive design enhances performance by delivering content tailored to specific devices and contexts. This includes serving device-specific resources, such as optimized image resolutions or lower-quality assets for users on slower networks. For instance, using the `<picture>` element and the `srcset` attribute enables browsers to choose the best image version based on the device's capabilities.To further improve efficiency, adaptive loading techniques can be used to detect the user's network speed and dynamically adjust the quality or size of assets like images and videos. Combining responsive and adaptive principles ensures a PWA remains visually consistent and performant, regardless of the user's device or network conditions. Employing these strategies not only enhances accessibility but also minimizes resource wastage, ensuring a faster and more satisfying experience for users globally.4. Optimize JavaScript Delivery:Efficient JavaScript delivery is a cornerstone of PWA performance optimization, as excessive or poorly managed scripts can significantly delay page loading and interaction. The first step in optimizing JavaScript is to reduce its size through techniques like minification, which removes unnecessary characters, and tree shaking, which eliminates unused code. These practices streamline the payload, ensuring only essential code is delivered.Another critical strategy is code splitting, where large JavaScript bundles are broken into smaller, manageable chunks. This allows browsers to load only the code required for the current page or interaction, deferring non-essential scripts until they are needed. Using modern JavaScript module formats, such as ES6 modules, further enhances modularity and performance.Async and defer attributes play a vital role in optimizing script loading. Scripts marked with `async` load in parallel with the HTML parsing, while `defer` ensures scripts are executed only after the HTML is fully parsed. These attributes prevent blocking of critical rendering paths.Additionally, “lazy loading JavaScript” can delay the execution of non-critical scripts until after the main content is loaded, improving time-to-interactive (TTI). Regular performance audits using tools like Google Lighthouse ensure JavaScript delivery remains optimized and aligned with evolving application requirements.5. Prioritize Core Web Vitals:Core Web Vitals are a set of performance metrics defined by Google to measure the quality of user experiences on the web, focusing on loading speed, interactivity, and visual stability. Prioritizing these metrics ensures a PWA is both user-friendly and optimized for search engine rankings.The first metric, Largest Contentful Paint (LCP), measures how quickly the largest visible content, such as a hero image or heading, appears. Optimizing LCP involves reducing server response times, using faster content delivery networks (CDNs), and implementing lazy loading for non-critical assets. Compressing images and using modern formats like WebP also accelerates content rendering.First Input Delay (FID) evaluates interactivity by measuring how quickly a page responds to user input. To improve FID, reduce JavaScript execution times by splitting bundles, offloading heavy tasks to web workers, and deferring non-essential scripts. Minimizing main-thread blocking ensures the app responds swiftly to user interactions.Finally, Cumulative Layout Shift (CLS) tracks unexpected layout shifts during loading. Preventing CLS involves reserving space for images, ads, and iframes with explicit dimensions and avoiding inserting dynamic content above existing elements.By prioritizing these metrics, PWAs deliver smoother, faster, and more reliable experiences, driving better user engagement and search engine performance.Final ThoughtsOptimizing your Progressive Web App (PWA) is essential to ensure it remains a powerful tool for your business. As user expectations continue to evolve, the ability to provide fast, reliable, and immersive digital experiences can set your business apart. By focusing on optimization, you're not just improving app performance but also aligning with key business objectives such as enhancing customer satisfaction, increasing user retention, and maximizing ROI.An optimized PWA ensures accessibility and reliability, even in low network conditions, making your platform a trusted resource for users. This reliability reflects your commitment to quality and innovation, strengthening your brand reputation.Moreover, as competition intensifies in the digital space, a high-performing PWA gives you a crucial advantage, allowing you to deliver value consistently while staying agile and adaptable to new technological advancements.

What Happens When All BTC Are Mined Bitcoin, the world's first decentralized cryptocurrency, operates on a system of scarcity. With a total supply cap of 21 million coins, Bitcoin is designed to mimic precious metals like gold, providing an anti-inflationary mechanism. But what happens when all Bitcoin (BTC) are mined? This question delves into the core of Bitcoin's design and its implications for miners, investors, and businesses leveraging blockchain technology. In this article, we explore the mechanics of Bitcoin mining, the role of block rewards, and the economic impact of reaching the 21-million cap. For related to crypto, visit our crypto development services.Understanding Bitcoin Mining and Supply CapBitcoin Mining: A Brief OverviewBitcoin mining is the process of validating transactions on the blockchain and adding them to the distributed ledger. Miners compete to solve complex mathematical problems, a process known as Proof of Work (PoW). The miner who successfully solves the puzzle is rewarded with a block reward, which consists of newly minted Bitcoin and transaction fees.Bitcoin's 21 Million Supply CapSatoshi Nakamoto, Bitcoin's pseudonymous creator, embedded the 21-million BTC cap into the protocol to ensure a finite supply. This cap, achieved through a deflationary issuance schedule, is enforced by Bitcoin's halving mechanism, which reduces the block reward by 50% approximately every four years.Also, Check | A Comprehensive Guide to the Runes Standard on BitcoinWhat Happens When All Bitcoin Are Mined?Transition to Transaction Fee-Driven RewardsOnce all 21 million BTC have been mined (estimated around 2140), miners will no longer receive block rewards for creating new blocks. Instead, their income will solely rely on transaction fees paid by users to have their transactions processed.Implications for MinersWithout block rewards, the profitability of mining will depend heavily on transaction volume and network fees. This raises concerns about miner incentives and the security of the network:Lower Incentives: Miners may reduce their participation if fees are insufficient to cover operational costs.Potential Centralization: Smaller miners may be forced out, leading to greater centralization among large mining operations.Impact on Security: A reduced number of miners could make the network more susceptible to attacks, such as the 51% attack.Transaction Fees and Network BehaviorAs block rewards diminish over time, transaction fees will play a more significant role in incentivizing miners. Businesses using the Bitcoin network must prepare for potentially higher fees, especially during periods of high transaction volume. This could make Bitcoin less attractive for micropayments but more appealing for large-value transactions.Bitcoin as a Store of ValueThe scarcity created by the 21-million cap enhances Bitcoin's role as "digital gold." With no new Bitcoin entering circulation after 2140, the focus will shift entirely to its existing supply. This scarcity is expected to maintain or increase its value, benefiting long-term investors and businesses holding Bitcoin as a reserve asset.You might also like | Demystifying Bitcoin Ordinals : What You Need to KnowThe Role of Layer 2 SolutionsTo address scalability and fee concerns, Layer 2 solutions like the Lightning Network will likely play a pivotal role. These networks enable faster and cheaper transactions by settling transactions off-chain while relying on the main Bitcoin blockchain for security.Economic and Business ImplicationsFor BusinessesHedging Against Inflation: Bitcoin's fixed supply offers businesses a hedge against fiat currency devaluation.Payment Integration: Businesses that accept Bitcoin payments may need to account for potential fee increases post-2140.Investment Opportunities: Institutional adoption of Bitcoin as a store of value could accelerate, making it a valuable asset in corporate treasuries.For the EconomyDeflationary Pressure: Bitcoin's scarcity may lead to deflationary trends in economies where it is widely adopted.Regulatory Developments: Governments may increase their scrutiny and regulation of Bitcoin as its significance grows.Also, Explore | Satoshi Nakamoto's Last Email Reveals Bitcoin Creator's ThoughtsFrequently Asked Questions (FAQs)1. What happens to miners when all Bitcoin are mined?Miners will no longer earn block rewards and will rely solely on transaction fees for income. This could alter the economic landscape of Bitcoin mining.2. Will Bitcoin become useless after reaching the 21 million cap?No. Bitcoin will continue to function as a decentralized network for value transfer and a store of value. Its fixed supply enhances its scarcity and desirability.3. How will transaction fees impact Bitcoin's usability?Transaction fees are expected to rise, especially during high-demand periods. Businesses and users may increasingly rely on Layer 2 solutions for cost-effective transactions.4. Why was Bitcoin limited to 21 million coins?The 21-million cap was designed to mimic the scarcity of precious metals like gold, creating an anti-inflationary digital asset.5. Can the Bitcoin supply cap be increased?Technically, yes, but it would require a consensus among network participants to alter Bitcoin's protocol. Given the decentralized nature of Bitcoin and the strong resistance to change, this is highly unlikely.ConclusionThe endgame for Bitcoin's 21-million cap marks a pivotal shift in its ecosystem. While it presents challenges, such as reliance on transaction fees and potential centralization of mining, it also reinforces Bitcoin's role as a scarce and valuable asset. Businesses and investors must prepare for this eventuality by adopting scalable solutions, monitoring fee structures, and understanding the broader economic impact of Bitcoin's finite supply. As we inch closer to 2140, Bitcoin's legacy as a revolutionary financial innovation will continue to evolve, shaping the future of decentralized finance.
