Wallets: Hot vs Cold Storage

🔐 Wallets: Hot vs Cold Storage

💡 What’s the Difference?

Feature Hot Wallet Cold Wallet

Internet Access Connected to the internet Offline storage (not connected to the internet)

Accessibility Fast, easy access for trading Slower access, best for long-term holding

Security More vulnerable to hacks & malware Highly secure from online threats

Examples Mobile apps, web wallets, desktop wallets Hardware wallets (e.g. Ledger, Trezor), paper wallets, air-gapped devices

Use Case Active trading, small amounts Long-term storage, large balances


🔥 Hot Wallets

Pros:


Convenient and user-friendly


Ideal for frequent transactions


Free or low-cost


Cons:


Exposed to phishing, keyloggers, and malware


Custodial hot wallets (like exchanges) can be hacked


Common Types:


Exchange wallets (e.g. Binance, Coinbase)


Browser extensions (e.g. MetaMask)


Mobile apps (e.g. Trust Wallet)


❄️ Cold Wallets

Pros:


Private keys stored offline


Resistant to online attacks


Ideal for storing large sums


Cons:


Less convenient for quick transactions


Physical loss or damage can be risky (if no backup)

Common Types:

Hardware wallets: USB-like devices (Ledger, Trezor)

Paper wallets: Printed QR codes and keys

Air-gapped systems: Isolated computers without internet

🧠 Rule of Thumb

Use Hot Wallets for small amounts or frequent trades.

Use Cold Wallets for savings, long-term holding, or storing large sums.

Think of hot wallets like a checking account, and cold wallets like a vault.

In this blog, we’ll walk through how to identify, access, and interact with frames and iframes using Playwright with code examples in JavaScript and Python. 🧾 What Are Frames and Iframes? <frame>: Rarely used now; part of the outdated <frameset> HTML structure. <iframe> (inline frame): Embeds another HTML page inside the current one. Common for third-party content like ads, maps, or payment gateways. 🎯 Why Frames Matter in Automation Elements inside an iframe are not part of the main DOM, so trying to interact with them directly will result in errors unless you switch the context to the frame. 🔍 Locating an Iframe in Pla...

Working with Tosca Parameters (Buffer, Dynamic Expressions)

🧪 Working with Tosca Parameters (Buffer, Dynamic Expressions) In Tricentis Tosca, parameters help you make your tests flexible, reusable, and data-driven. Two powerful types of parameters in Tosca are: Buffers Dynamic Expressions Let’s understand each one and how to use them effectively. 🟦 1. What is a Buffer in Tosca? A Buffer is a temporary in-memory storage used to store values during test execution. You can store a value in a buffer and then reuse it anywhere in your test case. 🔹 When to use: Save a value from one step and reuse it later Pass values between test steps or modules Dynamically build test data ✅ How to Create a Buffer In a Tosca TestStep, you use the syntax: text Copy Edit =>BufferName This saves a value to a buffer. Example: Capture an Order ID after placing an order: text Copy Edit ActionMode: Buffer Value: =>OrderID This stores the Order ID in a buffer named OrderID. ✅ How to Use a Buffer You can reuse the buffer value like this: text Copy Edit {B[OrderID]}...
