What are Smart Contracts?


Content:

Svmart contracts are one of the most powerful features of the Ethereum blockchain. They are digital agreements written in computer code that automatically execute when certain conditions are met.


For example, imagine you rent a house through a smart contract. The moment you pay the rent, the digital lock of the house opens automatically — no need for an agent or landlord to manually confirm.


Smart contracts are transparent, secure, and cannot be changed once deployed. They remove the need for middlemen and save time and cost.


Today, smart contracts are widely used in DeFi (Decentralized Finance), NFTs, and many other blockchain-based applications.

Title: Smart Contracts Kya Hain?


Content:

Smart contracts, Ethereum blockchain ki sabse powerful feature hai. Ye computer code mein likhe gaye agreements hote hain jo apne aap execute ho jate hain jab conditions poori ho jati hain.


Misal ke taur par, socho aapne ek ghar rent par liya smart contract ke zariye. Jaise hi aap rent pay karte ho, ghar ka digital lock apne aap khul jata hai — beech mein agent ya landlord ki zarurat nahi hoti.


Smart contracts transparent, secure aur permanent hote hain. Ek dafa deploy ho jayein to unko badla nahi ja sakta. Ye middleman ki zarurat khatam kar dete hain aur waqt aur paisa dono bachaate hain.


Aaj kal smart contracts DeFi, NFTs aur bohot se blockchain apps mein use hote hain.

What is Futures Trading in Crypto?

 🟢 English Version What is Futures Trading? Futures trading is a type of agreement where you buy or sell a cryptocurrency at a set price on a future date. Instead of owning the actual crypto, you are only betting on its price going up or down. For example, if you think Bitcoin’s price will go up, you can take a “long position”. If you think it will go down, you can take a “short position”. If your prediction is correct, you make profit. If it’s wrong, you lose money. How Does It Work? You don’t need to own crypto to trade futures. You only need margin (a small amount as security). Exchanges allow leverage (like 5x, 10x, or even 100x), which multiplies both profit and loss. Settlement happens on the date of contract expiry. Risks for Beginners Leverage can quickly wipe out your funds. Market moves fast; one wrong prediction = big loss. Futures are better for experienced traders, not complete beginners. 👉 Futures trading can be profitable but it is highly risky. Beginners should fi...

What is a Crypto Wallet?

Hot Wallets – These are connected to the internet (like mobile apps or online platforms) and are convenient but slightly less secure. 2.
