You've learned about Raydium's unique technology and its role as a liquidity hub on the Solana blockchain. Now it's time to move from theory to practice. Interacting with a Decentralized Exchange (DEX) for the first time can seem intimidating, but it's a straightforward process once you know the steps.

This guide will be your walkthrough. I'll show you exactly how to use Raydium, from setting up your wallet to making your first token swap.

Before You Begin: What You'll Need

To interact with any application on Solana, you need two things first:

• A Solana-Compatible Wallet: This is a non-custodial wallet that allows you to interact with the Solana blockchain. The most popular choice by far is the Phantom wallet, which works as a simple browser extension.
• SOL Tokens: You will need SOL, the native cryptocurrency of the Solana blockchain, in your wallet. SOL is used to pay for network transaction fees (often called "gas"). The good news is that Solana's fees are incredibly low, so you only need a small amount (e.g., 0.1 SOL) to get started.

Step 1: Acquire Your Assets on a Secure Exchange

Your journey into DeFi begins with a secure foundation. The first step is to acquire the necessary tokens—SOL for gas fees, and any other asset you wish to trade, like USDC or RAY—on a trusted centralized exchange.

Step 2: Set Up Your Phantom Wallet

If you don't have one already, go to the official Phantom wallet website (phantom.app) and add the extension to your browser. Follow the setup instructions carefully. Crucially, write down your 12-word secret recovery phrase and store it in a secure, offline location. Never share this phrase with anyone.

Step 3: Transfer Funds from Exchange to Phantom

Once your Phantom wallet is ready, you'll see your unique Solana address at the top.

1. Go to your wallet on an exchange platform of your choice.
2. Select the asset you want to withdraw (e.g., SOL).
3. Copy your Phantom wallet address and paste it into the "withdrawal address" field.
4. Confirm the transaction and wait for the funds to arrive in your Phantom wallet.

Step 4: Connect Your Wallet to the Raydium Exchange

With your wallet funded, it's time to connect to the DEX.

1. Navigate to the official Raydium website (raydium.io).
2. In the top-right corner, you will see a "Connect Wallet" button. Click it.
3. A pop-up will ask you to choose your wallet. Select Phantom.
4. Your Phantom wallet will then ask for your permission to connect to the site. Approve it.

Your wallet is now connected, and you are ready to trade.

Step 5: How to Swap Tokens on Raydium

The "Swap" interface is the core feature of the Raydium DEX.

1. Select the Token You Have: In the top field, choose the asset you want to trade from your wallet (e.g., SOL or USDC).
2. Select the Token You Want: In the bottom field, choose the asset you want to trade to (e.g., RAY).
3. Enter the Amount: Type in the amount you wish to trade. Raydium will automatically calculate the amount you will receive based on the current market price.
4. Review and Swap: Click the "Swap" button. Your Phantom wallet will pop up one last time to ask you to approve the transaction. Once you approve, the trade will be executed in seconds.

Congratulations! You've just successfully used one of the most powerful DEXs in DeFi.

WalletConnect is a protocol used by many crypto wallets that allows you to easily connect with the many DApps of decentralized finance (DeFi). Simply find the DApp you want to interact with, connect with a QR code or deep link, and you’re good to go. Always remember to disconnect at the end of any session for maximum security.

What is Wallet Connect?

Wallet Connect is an open-source protocol that allows you to connect your cryptocurrency wallet to decentralized applications (dApps) securely and easily. Instead of entering private keys or seed phrases on websites, Wallet Connect uses encrypted QR codes or deep links to establish a safe connection between your wallet (like MetaMask, Trust Wallet, or Rainbow) and the dApp.

This means you can interact with DeFi platforms, NFT marketplaces, and other blockchain services without exposing your sensitive wallet information online.

How Does Wallet Connect Work?

When you visit a dApp that supports Wallet Connect, you’ll see an option to “Connect Wallet.” Choosing Wallet Connect will display a QR code or link. You scan this QR code with your mobile wallet app or click the link if on mobile, and the wallet and dApp establish a secure session.

This connection lets you approve transactions directly from your wallet app, adding a layer of security and convenience. You stay in control of your private keys, which never leave your device.

What is Wallet Connect Token?

The Wallet Connect token is a utility token associated with the Wallet Connect ecosystem. It is used to incentivize network participants, support protocol governance, and enhance the platform’s scalability and security. While Wallet Connect itself is a protocol, the token helps align interests and fund further development.

What is Wallet Connect Premarket?

The term wallet connect premarket often refers to early-stage or pre-launch phases of projects integrating Wallet Connect or related tokens. It can also mean the period before a token or service officially launches on exchanges. If you’re interested in such opportunities, always research carefully and beware of risks.

Why Use Wallet Connect?

• Security: Your private keys never leave your wallet.
• Convenience: Connect to multiple dApps without re-entering credentials.
• Compatibility: Works with many popular wallets and blockchains.
• User Control: Approve transactions directly from your wallet app.

Summary: Start Using Wallet Connect Today

Wallet Connect is a game-changer for crypto users who want a secure and easy way to interact with decentralized apps. Whether you’re trading NFTs, using DeFi, or exploring new blockchain projects, Wallet Connect keeps your assets safe while giving you seamless access.

In the world of crypto, the headlines can be unsettling. We’ve all seen the stories of major exchanges collapsing or decentralized protocols being hacked. It leaves every investor asking the same, critical question: "Where is my money actually safer?"

You have two main choices for trading: a Centralized Exchange (CEX) or a Decentralized Exchange (DEX). The debate over which is safer is one of the most important in crypto, and the answer isn't as simple as "one is good, one is bad."

As your guide, I'm not here to give you a one-size-fits-all answer. I'm here to help you understand the different types of risk each model presents, so you can make an informed decision based on your own skills and priorities.

The Short Answer: Understanding the Trade-Off

Here's the fundamental difference in security:

• On a CEX, you are trusting the exchange's security team, infrastructure, and financial stability to protect your funds. The risk is that this trusted third party could fail.
• On a DEX, you are trusting your own ability to secure your private keys and to interact with secure, well-audited smart contracts. The risk is that you will make a mistake or the technology will be exploited.

It's a trade-off between third-party risk and personal responsibility risk.

The CEX Security Model: The Bank Vault

Think of a CEX like a high-security bank vault. It offers robust, professional-grade protection that is often beyond the reach of an average individual.

The Strengths (Where a CEX is Safer):

• Professional Security Teams: CEXs employ world-class cybersecurity experts dedicated to preventing hacks.
• Insurance Funds: Many reputable exchanges maintain insurance funds (like SAFU—Secure Asset Fund for Users) to reimburse users in the event of a hack.
• User Safety Nets: If you forget your password, you can reset it. If you suspect a fraudulent transaction, you can contact customer support.
• Regulatory Oversight: Regulated exchanges are subject to audits and compliance standards, adding a layer of accountability.

The Risks (The "Not Your Keys, Not Your Coins" Problem):

The single, catastrophic risk of a CEX is custody risk. The exchange holds your private keys. If the exchange becomes insolvent, mismanages funds (as with FTX), or is subject to a government seizure, your funds are at risk. You are trusting them to be a good custodian.

The DEX Security Model: The Personal Safe

Think of a DEX like owning the world's most advanced personal safe. You, and only you, have the combination. This is the core principle of self-custody.

The Strengths (Where a DEX is Safer):

• Full Self-Custody: You hold your own private keys in your own wallet. Nocompany can go bankrupt and take your funds. No government can freeze your account. You have 100% control.
• No Central Point of Failure: There is no central server to hack or CEO to mismanage funds. The exchange is just code.

The Risks (The "You Are the Security" Problem):
With great power comes great responsibility. The risks of a DEX are technical and personal.

• Smart Contract Exploits: The DEX itself is code, and that code can have bugs. Hackers can exploit these bugs to drain funds from the protocol, and there is no one to reimburse you.
• Phishing & Scams: Scammers create fake websites and malicious tokens to trick you into signing transactions that drain your wallet. You are your only line of defense.
• Irreversible Mistakes: If you lose your seed phrase, your funds are gone forever. If you send crypto to the wrong address, there is no one to call to reverse it.

Security Risk Showdown: CEX vs. DEX

The Verdict: Which Is Safer for You?

• A CEX is likely the safer choice if you are a beginner, value the convenience of a safety net like customer support, and prefer to trust a regulated, insured entity with your security.
• A DEX is a powerful tool for advanced users who are confident in their personal security practices and whose highest priority is eliminating third-party custody risk.

For traders who want to operate in a regulated environment with professional-grade security and a support system to back them up, a trusted CEX remains the industry standard.

What Is United Polaris Business Class?

United Polaris is United Airlines’ flagship business class product, designed to elevate long-haul international and select transcontinental flights. Launched in 2016, it’s named after the North Star, symbolizing a guiding light for premium travelers.

Unlike standard United Business or United First (available on domestic routes), Polaris business class offers a fully immersive luxury experience, complete with lie-flat seats, exclusive lounge access, and elevated dining. It’s tailored for travelers who prioritize comfort and productivity, whether you’re jetting from New York to Tokyo or San Francisco to London.

Why Choose United Polaris?

For travelers in the U.S., Canada, or beyond, the appeal of Polaris flight lies in its promise to transform grueling long-haul journeys into restful, indulgent experiences. Whether you’re a business traveler needing to arrive sharp or a leisure traveler craving comfort, Polaris aims to deliver. But with a premium price tag, understanding the full scope of what you’re paying for is crucial.

Breaking Down the United Polaris Cost

The United Polaris cost can be a shock to the system, with one-way tickets often starting around  $3,000 and climbing to $11,000 or more, depending on the route, season, and booking window. For example, a round-trip from Newark (EWR) to Tokyo (HND) can range from $6,600 to $10,000, while shorter routes like Newark to London may dip as low as $1,700 one-way if you snag a deal.Factors Affecting United Polaris Cost

Route and Distance: Longer flights, like those to Asia or Australia, command higher prices. For instance, a San Francisco to Sydney flight may cost upwards of $5,000 one-way.

Booking Timing: Prices fluctuate based on demand. Booking midweek or during off-peak seasons (e.g., post-holiday periods) can save hundreds.

Miles and Points: Redeeming United MileagePlus miles (around 250,000 for a round-trip to Asia) or credit card points can significantly reduce costs.

Currency Considerations: For international travelers, costs in USD may feel steeper depending on exchange rates. Always check fares in your local currency for a clearer picture.

Is It Worth the Price?

For flights under 10 hours, some travelers find the cost hard to justify, as the full benefits (like ample sleep in a lie-flat bed) may not be fully utilized. However, for ultra-long-haul flights (12+ hours), the ability to arrive rested makes Polaris business class a game-changer. One traveler described sleeping for 10 hours on a San Francisco to Sydney flight, calling it absolute bliss.

What to Expect from a Polaris Flight

So, what is Polaris business class really like? Here’s a detailed look at the features that set it apart, ensuring you know exactly what you’re paying for.

1. Luxurious Lie-Flat Seats

The hallmark of United Polaris business class is its lie-flat seats, available in a 1-2-1 or 1-1-1 configuration for direct aisle access. Measuring 20.5–22 inches wide and up to 78 inches long, these seats transform into fully flat beds, perfect for sleeping. Odd-numbered rows by the window offer the most privacy, ideal for solo travelers, while middle seats suit couples.

Pro Tip: Choose seats like 3L or 7A for extra privacy and window views. Avoid bulkhead seats near galleys if you’re sensitive to noise.

2. Saks Fifth Avenue Bedding

United partners with Saks Fifth Avenue to provide plush bedding, including a cooling gel pillow, duvet, and lightweight blanket. For Nekton Dive Suit pajamas are available on flights over 14 hours, adding a cozy touch.

3. Exclusive Polaris Lounges

Access to United Polaris lounges (available at hubs like Newark, Chicago, and San Francisco) is a major perk. These lounges offer gourmet dining, shower suites, nap rooms, and open bars, far surpassing standard United Club lounges. If a Polaris lounge isn’t available, you’ll get access to United Club or Star Alliance lounges.

4. Gourmet Dining

The Polaris business class menu features multi-course meals with appetizers, salads, entrées, and desserts like made-to-order ice cream sundaes. While some travelers praise the freshness, others find the food inconsistent compared to top Asian or Middle Eastern carriers. Complimentary drinks, including premium wines and spirits, are included.

5. Amenity Kits and Entertainment

Expect a high-quality amenity kit (recently switched to Perricone MD branding) with skincare products, socks, an eye mask, and more. The 16-inch seatback screens offer hundreds of movies and shows, and Starlink Wi-Fi is rolling out in 2025 for faster connectivity.

The Pros and Cons of United Polaris

Pros

• Comfortable Sleep: Lie-flat beds and luxe bedding ensure restful flights.
• Exclusive Lounges: Polaris lounges elevate the pre-flight experience.
• Priority Services: Premier Access includes faster check-in, security, and boarding.
• Consistent Product: United’s fleet-wide rollout ensures a reliable experience.

Cons

• High Cost: Prices can be prohibitive without miles or discounts.
• Food Quality Varies: Some report underwhelming meals compared to competitors.
• Limited Storage: Seats may feel cramped for storing personal items.
• Inconsistent Service: Crew quality can vary, impacting the experience.

How to Book United Polaris for Less

The steep United Polaris cost doesn’t have to break the bank. Here are strategies to make it more affordable:

Use Miles or Points: Redeem United MileagePlus miles (check for PZ class availability) or transfer credit card points. Deals as low as $500 + 20,000 miles have been reported for 12-hour flights.

Book Early or Last-Minute: Fares can drop closer to departure, especially midweek.

Cryptocurrency continues to be a hot topic in 2025, but not every coin is a winner. While Bitcoin ended 2024 strong, many altcoins faced steep declines, earning the title of the worst cryptocurrency of the year. If you’re wondering what is the worst cryptocurrency or want to know the worst performing cryptocurrency to avoid, this article breaks down the biggest crypto losers of 2024 and what you should watch out for.

The Worst Cryptocurrency Names and Performers of 2024

The crypto market hit a total cap of $3.5 trillion at the start of 2025, showing overall growth. However, many altcoins struggled to keep up, with some losing over 50% of their value. These worst cryptocurrency names often share common problems: weak technology, poor management, and fierce competition.

Here are some of the worst-performing cryptocurrencies in 2024:

Arbitrum (ARB)

Arbitrum, once a promising Layer 2 scaling solution, suffered a massive 57.7% drop in 2024. Increased competition and scalability issues left it struggling to maintain investor confidence. Its failure to innovate quickly made it one of the worst cryptocurrencies last year.

Polygon (MATIC)

Polygon, another Layer 2 solution, fell by nearly 40%. Despite past success, it faced stiff competition and ongoing scalability problems. These challenges pushed Polygon into the worst performing cryptocurrency category for 2024.

Lido DAO (LDO)

Lido DAO, a decentralized staking platform, dropped 37.9% amid rising regulatory uncertainty and fierce competition in the staking sector. These factors made it one of the worst cryptocurrency names to hold last year.

Avalanche (AVAX)

Avalanche’s 23.7% decline was driven by a slowdown in developer activity and difficulties attracting decentralized apps (dApps). Despite its reputation, Avalanche became one of the worst performing cryptocurrencies in 2024.

Why These Cryptos Became the Worst Cryptocurrency

Several factors contributed to these coins’ poor performance:

• Increased competition: Newer, more efficient solutions stole market share.
• Scalability issues: Many struggled to handle growing user demand.
• Regulatory pressure: Uncertainty scared off investors, especially in DeFi and staking.
• Lack of innovation: Failure to adapt quickly led to loss of confidence.

The Worst States for Cryptocurrency Trading

If you’re trading in the U.S., be aware that states like New York and Texas have stricter crypto regulations. These can limit your access to certain coins or exchanges, making it harder to trade safely. Always check your state’s crypto laws before investing.

How to Avoid Investing in the Worst Cryptocurrency

Ever stared at your crypto wallet, wondering if Dogecoin will moon or leave you howling at the sky?  Millions are searching for the Dogecoin price prediction that’ll guide their next move. The fear of missing out—or worse, buying at the peak—keeps investors up at night.

But what if you could peek into the future and make a confident move? This post uncovers what’s driving Dogecoin’s value and hints at the promised land of savvy investing in 2025 and beyond. Ready to dig in?

Why BAT Crypto Could 10x Your Portfolio in 2025 – Don't Miss Out!

In the noisy and unpredictable world of cryptocurrencies, Bitcoin often steals the headlines while Ethereum takes the spotlight as the engine behind DeFi and smart contracts. Yet, hidden in plain sight is a token that has been quietly reshaping how we use the internet and how advertising works online. That token is the Basic Attention Token (BAT). Unlike the endless meme coins or speculative tokens that come and go, BAT has a clear, practical use case, and it’s tied to one of the most innovative browsers in existence today: Brave.

If you’re wondering what makes BAT so different, the answer is simple. It is not just a coin for traders looking for short-term profits. Instead, it represents a complete shift in how digital advertising operates. Traditional advertising online is broken. It invades your privacy, rewards publishers with pennies, and leaves users frustrated with constant pop-ups and slow browsing speeds. BAT was designed to fix that broken system by allowing users to choose to view privacy-respecting ads, earn tokens for their attention, and create a healthier ecosystem where publishers and advertisers get more value without relying on invasive tracking.

This vision didn’t come out of nowhere. BAT was launched back in 2017 by Brendan Eich, the creator of JavaScript and co-founder of Mozilla Firefox. That credibility alone gave the project a level of seriousness that most other altcoins lack. Since then, the token has steadily grown in adoption, powered by Brave browser’s rise as the go-to choice for privacy-conscious users.

Why BAT Token Matters in 2025

Fast forward to 2025, and the numbers speak for themselves. Brave browser has surpassed 50 million monthly active users, more than doubling in just a year. This kind of exponential growth is exactly what gives BAT real-world traction. The token isn’t just sitting idly in wallets; it fuels tipping systems for creators, unlocks premium features inside Brave, and provides advertisers with a smarter, privacy-first way to reach audiences.

Skeptics often ask: is BAT really legitimate, or is it just another token riding the crypto hype cycle? The truth is that BAT is as legitimate as it gets. Built as an ERC-20 token on Ethereum, it has been audited, integrated with major exchanges, and proven itself through years of actual utility. Unlike speculative projects that live and die on hype, BAT has carved out its niche in the  attention economy.

This doesn’t mean BAT is free from volatility. Just like every other cryptocurrency, it experiences wild swings in price. But unlike many tokens, BAT’s value is anchored to a real-world system with millions of users, which helps soften the blow of bear markets. Think of it less as a pump-and-dump coin and more as a utility-driven project slowly gaining adoption.

BAT Wallet Essentials

Of course, buying BAT is only part of the journey. Securing it properly is where many traders go wrong. Too many beginners leave their coins on exchanges, only to lose them in hacks or when platforms shut down. BAT gives you a much simpler path, thanks to Brave’s built-in wallet that integrates directly into the browser.

For those who prefer more flexibility, there are other options like MetaMask, which integrates with Brave seamlessly and opens the door to DeFi opportunities. Long-term holders often lean toward hardware wallets like Ledger for maximum security, keeping tokens offline and out of reach from hackers. For mobile-first traders who want convenience, wallets like Trust Wallet make it easy to monitor your BAT balance on the go. No matter which option you choose, the key is to secure your assets properly and never fall for phishing scams or fake exchange websites.

Setting up a BAT wallet takes just a few minutes, and for beginners using Brave, the process is almost effortless. You download the browser, activate the wallet, and you’re ready to start earning or storing tokens without dealing with complicated third-party apps.

How to Buy Basic Attention Token

Now, let’s address the big question: how exactly do you buy BAT? For many traders, the biggest worry is finding a safe and affordable way to get in without being burned by high fees or unreliable exchanges. The good news is that BAT is widely available on the largest and most trusted trading platforms in the world.
