Whoa! Here’s the thing. I was digging through a messy transaction the other day and something felt off about how the logs were presented. My instinct said the explorer wasn’t showing the full story—so I went deeper. Initially I thought it was just a UI quirk, but then realized that the real problem was a mix of inner instructions, pre/post balances and a confused fee-payer that hid the token flow. Seriously? Yep.
Explorers on Solana are part detective tool, part developer console. They let you follow a signature from the moment it’s submitted, through confirmations, and into the ledger where account states change. Short answer: if you want to understand what happened to SOL or an SPL token (including NFTs), an explorer is the fastest way to get the forensic picture. But there’s nuance. On one hand an explorer gives you decoded instructions and program logs; on the other hand it sometimes omits context you only get from full RPC queries or program-specific parsers.
Okay, so check this out—when you open a transaction page you’ll often see these core pieces: signature, status (confirmed/failed), block time, fee payer, compute units used, and a decoded list of program instructions. Most explorers show token balance deltas (pre / post) for accounts; that is your single best clue for where tokens actually moved. If the balance deltas don’t match what you expect, look to inner instructions. That’s where program A calls program B, and a transfer occurs deep inside the call stack.
Here’s a quick mental checklist I use when tracking a suspicious SOL transaction:
- Find the signature and check status. Short step. Big payoff.
- Scan decoded instructions. Look for SystemProgram.transfer, TokenProgram.transfer, or custom program calls.
- Compare pre/post balances for the accounts of interest. That usually shows who sent what to whom.
- Read program logs for emitted events or error messages. They often tell the backstory.
- Note the fee payer and compute usage—expensive runs can hint at loops or heavy computation.
For NFTs, it’s a slightly different rhythm. NFTs on Solana typically follow the Metaplex metadata standard: there’s a mint address, a token account that holds the NFT, and off-chain JSON that describes the artwork and attributes. When you inspect a transfer, verify the mint, then check the token account owner before and after the tx. If the explorer shows a “verified” creator badge, that means the collection has gone through a particular on-chain verification flow—handy when checking authenticity. (oh, and by the way… compressed NFTs are a newer pattern and can look different in explorers.)

Why different explorers matter — and my go-to
Explorers have personalities. Some are minimalist and fast; others decode program-specific events and surface NFT metadata right away. I’m biased, but I usually start with Solscan for a deep look because it gives lots of decoded info and token metadata in one place. If you’re just after raw, canonical data, the official Solana Explorer or a direct RPC call will be your friend. For a practical readme and walkthrough I often point folks to a concise resource I trust: https://sites.google.com/mywalletcryptous.com/solscan-blockchain-explorer/.
Developers: pay attention to these common pitfalls. First, transaction simulation can behave slightly differently from execution under full network load—so a simulated success isn’t a guarantee. Second, decoding custom programs requires program-specific parsers; explorers try to help, but they won’t always interpret bespoke instruction layouts correctly. Third, watch for wrapped SOL vs native SOL movements: wrapped SOL (WSOL) uses token accounts and can confuse a quick skim.
Pro tips I use daily:
- Use the signature to chain queries: explorer → getTransaction RPC → parse logs locally if needed.
- When debugging a failed transaction, start with the first error in logs—later logs usually cascade from that failure.
- For NFTs, track both the mint and the metadata account (Metaplex metadata). Ownership changes on token accounts, not the metadata itself.
- Bookmark common program IDs (Token Program, Memo, Metaplex) so you can spot patterns faster.
Something I still find a little annoying: explorers sometimes hide low-level inner instructions behind “show more” toggles, and you miss a crucial transfer unless you expand everything. That’s human behavior for you—skim, assume, and miss the tiny but important detail. I’m not 100% sure why all explorers don’t default to expanded inner instructions, but maybe it’s a UX tradeoff. Anyway, dig in. Expand. You’re welcome.
For wallet users tracking an incoming NFT purchase: look for the mint, verify the seller’s address, confirm the marketplace instruction (if any), and check royalties or creator fields to ensure they align with the collection. If something smells off—like the creator is unverified or metadata points to an unexpected URL—pause. Seriously. Pause and ask.
If you’re building tooling, consider these features users love: human-readable instruction names, clear pre/post balance tables, ability to filter inner instructions, NFT metadata preview with image thumbnails, and quick links to the mint and collection pages. Also add signals for high compute usage or unusually high fees—those are red flags.
Finally, monitoring at scale requires different tactics. Wallets and analytics platforms pull indexed data rather than relying on live explorer pages. They index token transfers, maintain ownership mappings, and surface alerts for big moves or suspected rug pulls. If you want real-time watching, set up a WebSocket subscription to relevant accounts or use a third-party indexer. My instinct says start small: watch a handful of addresses, validate alerts, then scale up.
FAQ — Quick answers
How do I find a transaction by signature?
Paste the signature into an explorer’s search box. If you need programmatic access, call getTransaction (or your SDK’s equivalent) to fetch decoded instructions, logs, and balance changes.
How can I verify who owns an NFT now?
Look up the mint, then check token accounts that hold that mint. The owner of the token account is the current holder. Also inspect the metadata for creator verification badges.
What does a failed transaction tell me?
Read the earliest program log error. Often the failure is due to insufficient funds, account not initialized, or an instruction assertion. Use simulation locally to iterate before resubmitting.
Okay—I’ll be honest: explorers won’t solve every mystery. They do, however, give you the critical breadcrumbs. If you take nothing else from this, remember: check signatures, expand inner instructions, and compare pre/post balances. Good luck out there.
