What Is a Stablecoin?

 A stablecoin is a type of cryptocurrency designed to maintain a stable value, typically by being pegged to a real-world asset, such as a fiat currency (like the U.S. dollar) or a commodity (like gold). The goal of stablecoins is to combine the stability of traditional currencies with the flexibility and speed of digital assets.


Types of Stablecoins

Fiat-Collateralized Stablecoins


Backed 1:1 by a fiat currency (e.g., USD).


Examples: USDT (Tether), USDC (USD Coin), BUSD (Binance USD)


Held in reserve by a central authority or third-party custodian.


Crypto-Collateralized Stablecoins


Backed by other cryptocurrencies (usually overcollateralized to handle volatility).


Example: DAI (by MakerDAO)


Managed by smart contracts on a blockchain.


Algorithmic Stablecoins


Use algorithms and smart contracts to control the supply and demand of the token to maintain its peg.


Not backed by reserves; instead, supply is expanded or contracted automatically.


Example: Ampleforth (AMPL), though many have failed (e.g., TerraUSD).


Commodity-Collateralized Stablecoins


Backed by commodities like gold or oil.


Example: PAX Gold (PAXG)


Why Are Stablecoins Important?

Reduced Volatility: Useful for trading and as a store of value in the crypto space.


Efficient Transactions: Enable fast, low-cost transfers globally.


DeFi Integration: Widely used in decentralized finance (DeFi) applications as collateral or for yield farming.


Remittances & Payments: Provide a stable medium of exchange for international payments.


Risks

Centralization: Fiat-backed coins often rely on trust in centralized entities.


Regulatory Issues: Increasingly under scrutiny by financial regulators.


Collateral Risks: If reserves aren’t properly managed or audited, the peg could break.


Algorithmic Instability: Algorithmic stablecoins can collapse under stress (e.g., TerraUSD crash in 2022).

Handling Frames and Iframes Using Playwright

Handling Frames and Iframes Using Playwright When automating modern web applications, you’ll often come across frames or iframes—HTML elements used to embed another HTML document within the current page. If you're using Playwright for browser automation, knowing how to handle frames properly is crucial for interacting with elements inside them. 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...
