What this Ethereum blockchain explorer shows you
Every action on Ethereum leaves a public record: a transfer, a token swap, an NFT mint, a contract deployment. A block explorer turns that record into something a person can read. This page is our own lightweight explorer. It sits on top of open data and gives you the answer most people are actually looking for in a few seconds: did my transaction go through, how much did it cost, and what is sitting in this wallet?
Paste something into the search box above and the tool works out what it is. A string that starts with 0x and has 64 hex characters after it is treated as a transaction hash (and, if no transaction matches, as a block hash). Forty hex characters means an address. A plain number is a block height. Anything ending in .eth is resolved through the Ethereum Name Service, and any other text runs a token and label search, so typing USDC or Uniswap works too.
Transaction lookups
For a transaction, you get the status first, because that is what matters: Success, Failed or Pending. Below it sit the block number and the number of confirmations, the timestamp in UTC, the sender and recipient (with ENS names and contract markers where available), the value in ETH with its dollar equivalent, and the total fee. We also break the fee down the way EIP-1559 defines it: base fee, max fee, priority tip and the amount that was burnt. If the transaction called a contract, you will see the decoded method name, any ERC-20 or NFT transfers it triggered, and the raw input data if you want to dig further.
One detail you will not find on most explorers is the beacon chain slot and epoch. Since the Merge in September 2022, Ethereum produces a slot every 12 seconds and groups 32 slots into an epoch. We calculate both from the block timestamp so you can cross-reference a transaction with validator data on a beacon chain explorer.
Address and wallet lookups
An address page opens with the ETH balance and its current USD value, the number of transactions and token transfers, and a count of ERC-20 tokens and NFTs the address holds. Contracts get extra labels: whether the source code is verified, whether it is a proxy, and who deployed it. If the address is itself a token contract, such as USDT or WETH, you also see price, holders, total supply and market cap. The tabs underneath switch between recent transactions, token transfers and the full token list. Addresses that data providers have flagged as scams are marked in red, which is worth a second look before you interact with anything.
Want to learn what each of those numbers means for your own security? Our guide to the Ethereum address explorer walks through balances, approvals and the signs of a drained wallet.
Blocks, gas and the network pulse
With an empty search, the tool shows a live overview of the chain that refreshes every 12 seconds, roughly once per block. You see the latest blocks with their gas usage, the latest transactions, the average gas price in gwei, the number of transactions in the past 24 hours and the ETH price. Open any block for its fee recipient (the validator’s payout address), the gas used against the gas limit, burnt fees, priority fees, blob transactions and blob gas, and the count of validator withdrawals it processed. Previous and next buttons let you walk the chain block by block.

Mainnet, Sepolia, Hoodi and Ethereum Classic
The network switcher sits next to the search box. Mainnet is where real value moves. Sepolia is the testnet the Ethereum Foundation recommends for application and smart contract testing, and Hoodi, launched in March 2025, replaced Holesky for validator and staking tests. Holesky itself was shut down after the Fusaka upgrade, so if you have an old Holesky hash, it will not resolve anywhere. We also include Ethereum Classic, the proof-of-work chain that split from Ethereum in 2016 and still runs today. Read more in our guides to testnet explorers and Ethereum Classic explorers.
Where the data comes from
We built this explorer for static hosting, which means there is no server of ours between you and the blockchain. Your browser talks directly to two kinds of public infrastructure. The primary source is the Blockscout API v2, a widely used indexer whose code is publicly available, running on eth.blockscout.com and exposes transactions, addresses, tokens, ENS names and statistics without an API key. If that source is slow or unavailable, the tool falls back to public JSON-RPC nodes (PublicNode, dRPC and 1RPC) and reads the raw data straight from the chain using the standard Ethereum JSON-RPC methods. The RPC fallback returns fewer fields, such as no token labels, and you will see a small notice when it is in use.
Prices come from the same indexer, which sources them from CoinGecko. We deliberately did not use services that require a secret key, such as the Etherscan API, because a key embedded in browser code is visible to everyone and would quickly be abused. If you are building something similar, our comparison of Ethereum explorer APIs covers free tiers and rate limits in detail.
Reading the result like a pro
A few habits make an explorer far more useful. First, look at the confirmations, not just the status. A transaction in the latest block is included but not yet final. After two epochs, about 13 minutes, it is finalized and cannot be reversed without an enormous, visible attack. Exchanges usually wait for a set number of confirmations before crediting a deposit, which explains why your funds can show on-chain before they show on your exchange balance.
Second, compare the gas used with the gas limit. A plain ETH transfer uses exactly 21,000 gas. A token transfer typically uses 45,000 to 65,000. If a failed transaction used 100% of its limit, it most likely ran out of gas, and the fix is a higher limit rather than a higher price. Third, check the to address. When you send USDT, the “to” field is the USDT contract, and the actual recipient appears under token transfers. That catches many people out when they think they sent money to the wrong place.
Finally, treat labels as hints, not guarantees. A verified contract is one whose source code matches what is deployed, which is a good sign but says nothing about whether the code is honest. Scam flags are helpful, but a missing flag does not make a token safe. Our token explorer guide and smart contract guide explain what else to check.
Privacy and limits
Blockchain data is public, but your interest in a particular address does not have to be. We do not log searches, set tracking cookies for the tool or send your queries anywhere except to the data provider that answers them. That provider can see your IP address, as any website you visit can. For stronger privacy, use a VPN or run your own node with a local explorer; our open-source explorer guide shows how.
Public endpoints are shared by thousands of apps, so they have rate limits. If you click very quickly through many pages, you may see a “did not respond” message. Wait a few seconds and press Try again. For heavy research, the full explorers reviewed in our ranking of the best Ethereum explorers are the better tool.
