Key Takeaways
- Ethereum is a programmable blockchain enabling interaction with decentralized applications (dApps). Its native cryptocurrency is Ether (ETH).
- Smart contracts—self-executing code on the blockchain—power Ethereum’s ecosystem, enabling programmable money and dApps.
What Is Ethereum?
Launched in 2015 by Vitalik Buterin, Ethereum is a global platform for decentralized applications, digital currency transactions, and smart contracts. As the first blockchain to introduce smart contracts, Ethereum revolutionized digital agreements by automating execution when conditions are met.
Example: DeFi Loans
Traditional loans require credit checks and paperwork. With DeFi, smart contracts enable instant, permissionless borrowing using crypto collateral—no banks needed.
What Is ETH?
Ether (ETH) is Ethereum’s native currency, used for:
- Gas fees: Transaction costs paid to network validators.
- Value transfer: Peer-to-peer payments, like paying for services in ETH.
ERC-20 Tokens Explained
ERC-20 is the standard for creating fungible tokens on Ethereum. These tokens:
- Power dApp economies (e.g., Uniswap’s UNI).
- Are interchangeable but unique to their respective dApps.
What Can You Do on Ethereum?
1. Swap Tokens on Decentralized Exchanges (DEXs)
DEXs like Uniswap allow trustless trading without KYC. Unlike centralized exchanges (CEXs), DEXs give users full asset control.
How to Swap:
- Phantom Wallet: Swap ETH for ERC-20 tokens in-app.
- Uniswap: Connect your wallet, trade tokens, or provide liquidity for rewards.
2. Participate in DeFi
Ethereum’s DeFi ecosystem offers:
- Lending/Borrowing: Platforms like Aave let you earn interest or take loans using crypto collateral.
- Yield Farming: Stake assets in liquidity pools for passive income.
3. Trade NFTs
NFTs represent ownership of digital/physical assets. Popular marketplaces:
- OpenSea: Largest NFT marketplace for beginners.
- Blur: Low-fee platform favored by traders.
Notable NFT Collections:
- Azuki: Anime-inspired PFP project with metaverse access.
- World of Women (WoW): Celebrates diversity in Web3.
- OMGKirby: Music NFTs with full usage rights.
The Future of Ethereum
Ethereum remains the leader in dApp activity but faces scalability challenges. Upgrades like Ethereum 2.0 and layer-2 solutions (e.g., Polygon) aim to reduce fees and improve speed.
FAQs
1. How do I buy ETH?
Purchase ETH via exchanges like OKX, or directly in wallets like Phantom using MoonPay or PayPal.
2. What’s the difference between ETH and ERC-20 tokens?
ETH is Ethereum’s native currency, while ERC-20 tokens are assets built atop Ethereum (e.g., USDT, UNI).
3. Are smart contracts safe?
While generally secure, always audit contract code or use audited dApps to minimize risks.
4. Why are Ethereum gas fees high?
Fees spike during network congestion. Layer-2 solutions help reduce costs.
5. Can I earn passive income with Ethereum?
Yes! Stake ETH, provide liquidity, or lend assets via DeFi protocols.
