You simply despatched ETH to a pal, and thirty seconds later, you continue to don’t know if it labored. Etherscan solutions that query in a single search. It’s a free web site that exhibits each transaction, pockets stability, and sensible contract on the Ethereum community, pulled straight from the blockchain in actual time.

A couple of phrases come up always, so it helps to know them upfront. A pockets handle is the general public string of characters, often beginning with “0x,” that identifies the place funds are despatched or held. A transaction hash (typically shortened to “tx hash”) is the distinctive receipt quantity for a single switch.
Gasoline is the price paid in ETH to get a transaction processed, and a wise contract is the self-executing code behind issues like token swaps, NFT mints, and DeFi lending. Search any of those phrases into the Etherscan homepage and it’ll pull up the matching report.
Etherscan isn’t restricted to Ethereum’s essential community anymore both. Its API now runs on a single key throughout greater than 60 supported EVM-compatible chains, and its Blockscan product tracks exercise throughout networks constructed to scale Ethereum, often known as Layer 2s. That issues as a result of a rising share of on a regular basis exercise, low cost swaps, gaming transactions, small transfers, now occurs off the principle Ethereum chain, and Etherscan’s instruments comply with that exercise somewhat than staying locked to at least one community.
