Crypto investments have seen a meteoric rise over the years, and as more people join the blockchain revolution, the security of one's assets has become paramount.

Hardware wallets, often dubbed "cold storage", provide a secure method to keep digital assets safe from cyber threats and that’s why when it comes to securing your crypto assets, choosing the right hardware wallet is crucial.

In this post, we’ll explore the 6 best hardware wallets in 2023 for safe crypto storage, ensuring your digital investments are well-protected. 

What are Crypto Hardware Wallets?

Hardware wallets, commonly known as "cold wallets," are physical devices designed to securely store cryptocurrency private keys offline. These tools protect assets from online threats like hacks and malware since they keep private keys isolated from internet-connected devices.

To execute a transaction, users connect their hardware wallet to a device, sign the transaction offline, ensuring utmost security, and then broadcast it online. 

This method ensures the private keys remain inaccessible even if the connected device is compromised. As a result, hardware wallets are widely recognized as a top-tier security measure for crypto investors.

Things to Consider While Choosing Crypto Hardware Wallets

When selecting a crypto hardware wallet, several factors demand careful consideration. 

1. Security features are paramount; ensure the wallet provides offline storage and employs advanced cryptographic techniques. 

2. Evaluate its build quality—a sturdy construction can prevent physical tampering. User experience is crucial; the interface should be intuitive, with clear instructions and prompts. 

3. Consider the range of supported cryptocurrencies—a broad spectrum can future-proof your investment. 

4. Look into any associated software; it should offer seamless integration and regular updates. 

5. Lastly, community reviews and feedback can offer real-world insights into the device's reliability and performance. By balancing these factors, users can confidently choose a wallet tailored to their needs.

Frequently Asked Questions

Q1. What's the difference between a hardware wallet and a software wallet?

A hardware wallet is a physical device that securely stores a user's private keys offline, while a software wallet is a digital application on a computer or smartphone that keeps keys typically online or in the device's memory.

Q2. How often should I update my hardware wallet's firmware?

Regularly updating the firmware ensures you benefit from the latest security patches and features. Always follow the manufacturer's recommendations and ensure updates come from official sources.

Q3. Can I store multiple cryptocurrencies on a single hardware wallet?

Yes, most modern hardware wallets support multiple cryptocurrencies. However, it's essential to check the supported coins list for your specific device model.

Q4. What happens if I lose my hardware wallet or it gets damaged?

If you've kept a backup of your recovery seed—a series of words given during the initial setup—you can restore your funds on a new device. Always store your recovery seed securely and offline.

Q5. Is it safe to buy a used hardware wallet?

It's generally recommended to purchase hardware wallets new and directly from the manufacturer or trusted retailers to prevent potential tampering.

Q6. How does a hardware wallet interface with blockchain networks if it's offline?

The wallet itself only signs transactions offline. To broadcast the transaction to the network, the signed transaction is sent through a connected device, ensuring private keys remain offline.

Q7. Are hardware wallets resistant to physical attacks?

Many modern hardware wallets come with tamper-proof features. However, physical security is always crucial. Ensure you store your device in a safe place, and always be wary of potential tampering if left unattended.

Q8. Can I use my hardware wallet with popular software wallets or exchanges?

Most renowned hardware wallets integrate with popular software wallets and exchange platforms, allowing users a seamless experience. Always check compatibility lists before making a purchase.

In 2023, these eight hardware wallets stand out for their unique features, security, and ease of use. Remember to consider your specific needs and requirements when choosing a hardware wallet for your crypto assets. 

With the options listed above, you can ensure the safety and security of your investments, keeping your crypto assets protected against unauthorized access and potential threats.

Remember, while technology provides tools for security, the best protection is always awareness and education. Ensure you're up-to-date with best practices and always double-check transactions and addresses. Your crypto assets are valuable, and they deserve the highest level of care and protection.

🛠️ What You’ll Need

  • A free Token Metrics API key
  • A Google account
  • Basic familiarity with Google Sheets

⚙️ How to Connect Token Metrics API to Google Sheets

Here’s how to get live AI-powered crypto data into Sheets using Google Apps Script.

🔑 Step 1: Generate Your API Key

  1. Visit: https://app.tokenmetrics.com/en/api
  2. Click “Generate API Key”
  3. Copy it — you’ll use this in the script

📄 Step 2: Create a New Google Sheet

  1. Go to Google Sheets
  2. Create a new spreadsheet
  3. Click Extensions > Apps Script

💻 Step 3: Paste This Apps Script

const TOKEN_METRICS_API_KEY = 'YOUR_API_KEY_HERE';

async function getTraderGrade(symbol) {

  const url = `https://api.tokenmetrics.com/v2/trader-grades?symbol=${symbol.toUpperCase()}`;

  const options = {

    method: 'GET',

    contentType: 'application/json',

    headers: {

      'accept': 'application/json',

      'x-api-key': TOKEN_METRICS_API_KEY,

    },

    muteHttpExceptions: true

  };

  

  const response = UrlFetchApp.fetch(url, options);

  const data = JSON.parse(response.getContentText() || "{}")

  

  if (data.success && data.data.length) {

    const coin = data.data[0];

    return [

      coin.TOKEN_NAME,

      coin.TOKEN_SYMBOL,

      coin.TA_GRADE,

      coin.DATE

    ];

  } else {

    return ['No data', '-', '-', '-'];

  }

}

async function getSheetData() {

  const sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();

  const symbols = sheet.getRange('A2:A').getValues().flat().filter(Boolean);

  const results = [];

  results.push(['Name', 'Symbol', 'Trader Grade', 'Date']);

  for (const symbol of symbols) {

    if (symbol) {

      const row = await getTraderGrade(symbol);

      results.push(row);

    }

  }

  sheet.getRange(2, 2, results.length, results[0].length).setValues(results);

}

🧪 Step 4: Run the Script

  1. Replace 'YOUR_API_KEY_HERE' with your real API key.
  2. Save the project as TokenMetricsCryptoAPI.
  3. In your sheet, enter a list of symbols (e.g., BTC, ETH, SOL) in Column A.
  4. Go to the script editor and run getSheetData() from the dropdown menu.

Note: The first time, Google will ask for permission to access the script.

✅ Step 5: View Your Live Data

After the script runs, you’ll see:

  • Coin name and symbol
  • Trader Grade (0–100)
  • Timestamp

You can now:

  • Sort by Trader Grade
  • Add charts and pivot tables
  • Schedule automatic updates with triggers (e.g., every hour)

🧠 Why Token Metrics API Is Ideal for Google Sheets Users

Unlike basic price APIs, Token Metrics offers AI-driven metrics that help you:

  • Anticipate price action before it happens
  • Build signal-based dashboards or alerts
  • Validate strategies against historical signals
  • Keep your data fresh with hourly updates

And all of this starts for free.

🏗️ Next Steps: Expand Your Sheet

Here’s what else you can build:

  • A portfolio tracker that pulls your top coins’ grades
  • A sentiment dashboard using historical OHLCV
  • A custom screener that filters coins by Trader Grade > 80
  • A Telegram alert system triggered by Sheets + Apps Script + Webhooks

You can also upgrade to the Advanced Plan to unlock 21 endpoints including:

  • Investor Grades
  • Smart Indices
  • Sentiment Metrics
  • Quantitative AI reports
  • 60x API speed

🔐 Security Tip

Never share your API key in a public Google Sheet. Use script-level access and keep the sheet private unless required.

🚀Put Your $TMAI to Work: Daily Rewards, No Locks, Up To 200% APR.

Token Metrics Team
5 min
MIN

Liquidity farming just got a major upgrade. Token Metrics AI ($TMAI) has launched its first liquidity incentive campaign on Merk — and it’s designed for yield hunters looking to earn fast, with no lockups, no gimmicks, and real rewards from Day 1.

📅 Campaign Details

  • Duration: June 5 – June 19, 2025
  • Rewards Begin: 17:00 UTC / 1:00 PM ET
  • Total TMAI Committed: 38 million+ $TMAI
  • No Lockups: Enter or exit at any time
  • APR Potential: Up to 200%

For two weeks, liquidity providers can earn high daily rewards across three different pools. All rewards are paid in $TMAI and distributed continuously — block by block — through the Merkl platform.

💧 Where to Earn – The Pools (as of June 5, 17:00 UTC)

Pool                                                    Starting APR %               Total Rewards (14 days)                Current TVL

Aerodrome WETH–TMAI        150%                                16.79M TMAI (~$11,000)                   $86,400

Uniswap v3 USDC–TMAI        200%                                14.92M TMAI (~$9,800)                    $19,900

Balancer 95/5 WETH–TMAI    200%                                5.60M TMAI (~$3,700)                       $9,500

These pools are live and actively paying rewards. APR rates aren’t displayed on Merkl until the first 24 hours of data are available — but early providers will already be earning.

🧠 Why This Campaign Stands Out

1. Turbo Rewards for a Short Time

This isn’t a slow-drip farm. The TMAI Merkl campaign is designed to reward action-takers. For the first few days, yields are especially high — thanks to low TVL and full daily reward distribution.

2. No Lockups or Waiting Periods

You can provide liquidity and withdraw it anytime — even the same day. There are no lockups, no vesting, and no delayed payout mechanics. All rewards accrue automatically and are claimable through Merkl.

3. Choose Your Risk Profile

You get to pick your exposure.

  • Want ETH upside? Stake in Aerodrome or Balancer.
  • Prefer stablecoin stability? Go with the Uniswap v3 USDC–TMAI pool.

4. Influence the Future of TMAI Yield Farming

This campaign isn’t just about yield — it’s a test. If enough users participate and volume grows, the Token Metrics Treasury will consider extending liquidity rewards into Q3 and beyond. That means more TMAI emissions, longer timelines, and consistent passive income opportunities for LPs.

5. Built for Transparency and Speed

Rewards are distributed via Merkl by Angle Labs, a transparent, gas-efficient platform for programmable liquidity mining. You can see the exact rewards, TVL, wallet counts, and pool analytics at any time.

🔧 How to Get Started

Getting started is simple. You only need a crypto wallet, some $TMAI, and a matching asset (either WETH or USDC, depending on the pool).

Step-by-step:

  1. Pick a pool:
    Choose from Aerodrome, Uniswap v3, or Balancer depending on your risk appetite and asset preference.

  2. Provide liquidity:
    Head to the Merkl link for your pool, deposit both assets, and your position is live immediately.

  3. Track your earnings:
    Watch TMAI accumulate daily in your Merkl dashboard. You can claim rewards at any time.

  4. Withdraw when you want:
    Since there are no lockups, you can remove your liquidity whenever you choose — rewards stop the moment liquidity is pulled.

🎯 Final Thoughts

This is a rare opportunity to earn serious rewards in a short amount of time. Whether you’re new to liquidity mining or a DeFi veteran, the TMAI Merkl campaign is built for speed, flexibility, and transparency.

You’re still early. The best yields happen in the first days, before TVL rises and APR stabilizes. Dive in now and maximize your returns while the turbo phase is still on.

Token Metrics API Joins RapidAPI: The Fastest Way to Add AI-Grade Crypto Data to Your App

Token Metrics Team
5 min

The hunt for a dependable Crypto API normally ends in a graveyard of half-maintained GitHub repos, flaky RPC endpoints, and expensive enterprise feeds that hide the true cost behind a sales call. Developers waste days wiring those sources together, only to learn that one fails during a market spike or that data schemas never quite align. The result? Bots mis-fire, dashboards drift out of sync, and growth stalls while engineers chase yet another “price feed.”

That headache stops today. Token Metrics API, the same engine that powers more than 70 000 users on the Token Metrics analytics platform, is now live on RapidAPI—the largest marketplace of public APIs with more than four million developers. One search, one click, and you get an AI-grade Crypto API with institutional reliability and a 99.99 % uptime SLA.

Why RapidAPI + Token Metrics API Matters

  • Native developer workflow – No separate billing portal, OAuth flow, or SDK hunt. Click “Subscribe,” pick the Free plan, and RapidAPI instantly generates a key.

  • Single playground – Run test calls in-browser and copy snippets in cURL, Python, Node, Go, or Rust without leaving the listing.

  • Auto-scale billing – When usage grows, RapidAPI handles metering and invoices. You focus on product, not procurement.

What Makes the Token Metrics Crypto API Different?

  1. Twenty-one production endpoints

    Live & historical prices, hourly and daily OHLCV, proprietary Trader & Investor Grades, on-chain and social sentiment, AI-curated sector indices, plus deep-dive AI reports that summarise fundamentals, code health, and tokenomics.

  2. AI signals that win

    Over the last 24 months, more than 70 % of our bull/bear signals outperformed simple buy-and-hold. The API delivers that same alpha in flat JSON.

  3. Institutional reliability

    99.99 % uptime, public status page, and automatic caching for hot endpoints keep latency low even on volatile days.

Three-Step Quick Start

  1. Search “Token Metrics API” on RapidAPI and click Subscribe.
  2. Select the Free plan (5 000 calls / month, 20 request / min) and copy your key.
  3. Test:

bash
