Ethereum (ETH)
A blockchain for smart contracts and decentralized apps — powering most of Web3.
Ethereum (ETH) is a smart contract blockchain that lets anyone build apps,
not just send and receive crypto. It’s the foundation for DeFi, NFTs, and most of Web3.
Developers use Ethereum to create decentralized applications (dApps)
that run automatically on the blockchain — no middlemen, no banks, no downtime.
Why it matters
- Introduced smart contracts, enabling programmable money.
- Hosts thousands of tokens, NFTs, and DeFi protocols.
- ETH is used to pay gas fees — the cost of running transactions on-chain.
Ethereum’s upgrades
- Proof of Stake (PoS): replaced mining with energy-efficient staking.
- Layer-2 networks: like Arbitrum and Optimism, make Ethereum faster and cheaper.
💡 Lanzo Tip
Always check which network you’re using before sending ETH or tokens —
many use EVM chains that look similar but aren’t the same 🔗
