How to read a block explorer, and why you should
A block explorer is a website that reads a blockchain and shows you what's in it. That sounds mundane until you notice what it actually gives you: the ability to check your wallet's claims against the chain itself, rather than taking them on faith.
That's the whole point. Your wallet tells you a payment went through. An explorer lets you confirm it independently — and knowing how to read one turns "I think it worked?" into an answer.
The three things you can look up
A transaction, by its ID — a long hex string, sometimes called a txid or a hash. This is the receipt.
An address, showing its balance and every transaction it has ever been part of.
A block, containing the set of transactions confirmed at a particular moment.
Almost everything you'll ever need is the first one.
Reading a transaction page
Ignore most of the screen. Six fields carry the meaning.
Status. Pending or unconfirmed means it's broadcast but not yet in a block. Confirmed or success means it's in. On EVM chains there's a third state that trips people up: failed. A failed transaction is in a block — it happened, it consumed gas, it charged you — it just didn't do what it was supposed to. That's not a bug, it's how account-based chains work.
Confirmations. How many blocks have been built on top. Zero means it's in the mempool. One means it made it into a block. More means reversing it grows steadily more expensive.
Amount and fee, shown separately. Check both. The fee is where nasty surprises live, especially if your wallet estimated during a congested moment.
From and to. Verify the destination is what you intended. This is the moment to catch a mistake, though by now it's a diagnosis rather than a fix.
Timestamp. When it was included in a block — not when you sent it. On a congested chain the gap can be hours.
Inputs and outputs on UTXO chains, replaced by a simple from/to on account chains. If your Bitcoin transaction shows an output going to an address you don't recognise, don't panic: that's almost certainly your change. It's a real output going to a new address your wallet controls, and it's why change-address heuristics can link your addresses together.
When to actually reach for one
"I sent it and they say it hasn't arrived." Look up the txid. Either it's confirmed — in which case the problem is at their end, and you now have proof — or it's sitting unconfirmed, which is a fee problem with a known fix.
"It's been pending forever." The explorer shows the current fee rate. Compare it with yours and you'll know immediately whether you underbid.
"Did the airdrop / refund / payment arrive?" Look up your receiving address. This is faster and more trustworthy than waiting for a wallet to refresh.
"Is this contract safe?" Explorers show whether a contract's source code has been verified — meaning someone published source that provably compiles to the deployed bytecode. Unverified is not proof of malice, but it means nobody can read what they're about to interact with, and that's a genuine reason for caution.
"Is the chain itself healthy?" Block times and mempool size tell you whether the network is congested, stalled, or fine. During an incident this is often the fastest way to see what's actually happening.
What an explorer cannot tell you
This is the part that matters most, and it's where people get misled.
An explorer shows data, not truth about people. An address is not a name. Labels attached to addresses are guesses by the explorer's operator, often correct and sometimes not.
Some entries can be fabricated. On EVM chains a malicious token contract can emit a Transfer event that never moved anything, and explorers that trust event logs will display it. Not everything shown to you actually happened.
Balances of tokens can be meaningless. Anyone can create a token, name it whatever they like, and send it to you. A wallet showing "50,000 USDC-ish tokens" from a contract nobody recognises is showing you a fact about the ledger and nothing about value.
An explorer is a third party. It's a website run by someone, reading a node run by someone. If it's wrong or compromised, it will confidently show you wrong data. This is precisely why the practice of checking one at all is only meaningful if you understand whose view you're looking at.
Whose node are you actually reading?
Which brings us to something we should be straightforward about.
When you tap through to an explorer from SSP, where you land depends on the chain.
For EVM chains you go to a well-known third-party explorer — Etherscan for Ethereum, Polygonscan for Polygon, Basescan for Base, Snowtrace for Avalanche, BscScan for BSC, XDCScan for XDC. For Solana, Solana Explorer.
For UTXO chains and Flux, the link points at SSP's own infrastructure — blockbook-btc.sspwallet.io, blockbook-ltc.sspwallet.io, and so on, with Flux on flux-explorer.sspwallet.io.
That's worth naming plainly. For those chains, the explorer you're checking against is served by the same infrastructure that told your wallet the balance in the first place. It's convenient, it's fast, and it is not an independent check. If our node were wrong, the explorer would confidently agree with it.
For everyday use that's fine — you're confirming a txid exists and has confirmations, and the failure mode you're guarding against is usually your own uncertainty rather than infrastructure lying to you. But if you're verifying something that genuinely matters — a large payment, a disputed transfer, or anything during a network incident — paste the txid into a completely unrelated explorer as well. Two independent views agreeing is worth far more than one view you trust.
This is the same reasoning we applied to ourselves during Ravencoin's consensus incident: we didn't just check our own node was running, we compared its block hashes against the reference chain. Self-verification isn't verification.
The habit worth building
Look up your own transactions occasionally, even when nothing is wrong. It takes seconds and it builds an intuition — what a normal fee looks like, how long confirmation usually takes on a given chain, what your own change outputs look like.
That intuition is what makes an anomaly visible later. People who have never looked at an explorer can't tell the difference between "slow" and "broken," and end up either panicking over a normal delay or shrugging at a real problem.
The chain is public. Reading it is a skill, it's not difficult, and it's the only way to check your wallet's homework.
