Explorers by network
Every network has its own explorers, and one of the most common scams is a convincing copy of the one you were looking for.
An explorer reads one blockchain. An Ethereum explorer knows nothing about Solana, because they are separate systems with separate records. So the first question is always which network the transaction was on, and if you do not know that, you cannot look it up anywhere.
The directory lists the explorers themselves. This page is about choosing between them and reaching them safely.
One network, several explorers
Most networks have more than one, run by different people, all reading the same chain. They differ in layout, in the extras they add and in how much they try to sell you. None of them has privileged access to the data. If one shows your transaction and another does not, the second is behind, not better informed.
This is worth internalising because it removes the temptation to trust one brand. There is no authoritative explorer. There is only the chain, and several windows onto it.
What a multi-chain explorer is for
Some explorers cover many networks in one interface. They are useful in exactly one situation: you have an address or a hash and you are not sure which network it belongs to. Searching across chains at once answers that faster than trying four sites.
For day-to-day checks on a network you already know, a dedicated explorer usually shows more — the deeper fields, contract interactions and token details tend to be richer where the whole site is built around one chain.
The same address exists on several networks
An Ethereum-style address is valid on every Ethereum-style network, and they are different places. Coins sent on one network do not appear on another, even at an address that looks identical. Checking on the wrong explorer is the most common reason people conclude their coins vanished.
Fake explorers are a standing scam
Explorer names are short, familiar and easy to imitate: a near-identical domain, the same layout, the same colours. The copy exists to do one of two things.
Show you a transaction that never happened. A page built to order, displaying an incoming transfer of any amount the scammer likes. Convincing enough to make somebody release goods or send a counterpayment. A real explorer cannot be made to show a transaction that is not on the chain; a fake one shows whatever it was told to.
Ask you to connect a wallet. This is the version that costs money directly. Reading public data requires no wallet connection ever, so the request itself is the whole tell — see wallet drainers for what the signature you are asked to approve actually does.
Never reach an explorer through an advertisement
Paid search results for explorer names are bought by impostors regularly, because the audience is exactly the people about to check something important. Type the domain, or use a bookmark you made once from a source you trust.
Cross-checking, when it matters
If a transaction decides something — you are about to hand over goods, or release a payment — open a second explorer for the same network and search the same hash. Two independent sites showing the same record is close to conclusive. One site showing it and another showing nothing means you are looking at a fake, or at the wrong network.
This takes fifteen seconds and it is the only defence against the fabricated-transaction trick that does not depend on your eye for a domain name.
Bitcoin is a slightly different case
Bitcoin explorers show the same fields plus one that matters on that network: the fee market. Because Bitcoin blocks are produced roughly every ten minutes and space in them is limited, an explorer that shows the current queue tells you what fee is actually needed right now rather than what your wallet guesses. Fees and confirmations covers what the numbers mean.
