“A blockchain is transparent, but only if you know how to read it.”
— Vitalik Buterin, Co-founder of Ethereum

That’s what a block explorer does in crypto.
In this beginner’s guide, you’ll learn how to use Etherscan — the most popular Ethereum block explorer — to track transactions, verify smart contracts, and keep your crypto activities transparent and secure.

Sakshi, a beginner in crypto, tried sending ETH from MetaMask to an exchange. After 10 minutes, nothing arrived.
