Okay, so you're staring at your wallet after some Solana action and thinking, "Did that swap actually go through?" First thing I do? Copy the transaction signature. It's that long string of letters and numbers your wallet spits out right after you hit send. Paste it into Solscan or Explorer.solana.com, and boom-full details pop up in seconds. Why? Because signatures are like unique IDs for every tx on the chain. No waiting, no fluff.
In my experience, this beats scrolling endless wallet histories. Wallets hide stuff sometimes. Explorers show everything-fees, instructions, the works.
Look, Solana's fast as hell, but that speed means mistakes fly under the radar if you're not paying attention. Ever had a swap where you got less than expected? Or a stake that didn't activate? Checking txs catches that crap early. Plus, if you're in DeFi or staking, you gotta track approvals-some program might have permission to drain your tokens. Scary? Yeah. Fixable? Totally, if you know how to peek inside.
The thing is, one unrecognized tx could mean your keys got compromised. I've seen it happen to friends. They ignore it, poof-funds gone. So, get in the habit. It's your money.
Solscan, Explorer.solana.com, or Helius Orb if you're fancy. I usually stick to Solscan 'cause it's got killer filters for tokens and programs. Free, no login needed. But switch networks-mainnet beta for real stuff, devnet for testing. Wrong chain? You'll see nada.
Pro tip: Bookmark two. Cross check if something looks off. Explorers disagree sometimes on tiny details, but that's rare.
| Explorer | Best For | Quirks |
|---|---|---|
| Solscan | Token transfers, program filters | Super fast, CSV export |
| Explorer.solana.com | Raw JSON, official feel | Basic UI, but reliable |
| Helius Orb | Swaps, inner instructions | Enhanced views, might need account |
Honestly, start with Solscan. It's beginner proof.
Got a wallet you wanna audit? Like your main one or some shady airdrop receiver? Here's how.
Now, why does this matter? Say you're staking. Look for "Stake Program" interactions. Activation epoch wrong? Rewards might be delayed. I once missed a deactivation tx-lost a week's earnings. Won't happen again.
Filter by "Transfers" tab for just token stuff. Hides the noise from votes or whatever.
Transactions aren't just "send SOL". They're envelopes with instructions. Atomic too-if one fails, all roll back. Cool, right?
Inside: signatures (proof you approved it), message with account keys (wallets involved), recent blockhash (timestamp, expires quick), and instructions (the actions).
Picture this: You swap on Jupiter. Outer instruction calls Jupiter program. Inner ones hit Orca, Raydium-transfers USDC here, SOL there. Explorer shows the tree. Click "Instructions" tab. Expand inners. See compute units used (budget k per tx usually).
Fees? Base is tiny, 0.000005 SOL. But priority fees (you add 'em for speed) can hit 0.001 SOL on busy days. Check "Fee Payer"-should be your wallet.
Logs tab? Program spits out what happened. "SwapV2 success" or "TransferChecked". Errors? "Insufficient funds" or "Invalid account".
Raw JSON if you're nerdy. Toggle "enhanced" on Helius for readable version. Shows every account touched, ordered: signers first, then writables, read only.
You just sent 1 SOL to a friend. Wallet says "done". Verify it.
Short and sweet. Takes 10 seconds. But if it's a DEX tx? 20+ instructions. That's when you zoom into balances-did you get the right tokens?
Potential issue: "Slot not found". Means tx too fresh or failed early. Wait 10 secs, retry. Or use "Live" view on some explorers.
Staking's my jam. Track these:
For DeFi: Raydium swaps show pool interactions. Serum orders. Jupiter aggregates 'em. Always check approves-Token Program "Approve" to a program? Revoke if sketchy via wallet tools.
In my experience, custodials like exchanges mess this up. Their hot wallets show txs, but not your internal moves. Self custody all the way.
Wanna automate? Node.js script using @solana/web3.js. I do this for alerts.
First, setup:
mkdir sol tx check
cd sol tx check
npm init -y
npm install @solana/web3.js Now, log.js:
const solanaWeb3 = require('@solana/web3.js');
const connection = new solanaWeb3.Connection('https://api.mainnet beta.solana.com');
const searchAddress = 'YOURWALLETHERE'; const getTransactions = async (address, numTx) => { const pubKey = new solanaWeb3.PublicKey(address); let transactionList = await connection.getSignaturesForAddress(pubKey, {limit: numTx}); let signatureList = transactionList.map(tx => tx.signature); let transactionDetails = await connection.getParsedTransaction(signatureList, {maxSupportedTransactionVersion: 0}); transactionList.forEach((transaction, i) => { const date = new Date(transaction.blockTime * 1000); console.log(Tx ${i+1}: ${transaction.signature}); console.log(Time: ${date}); console.log(Status: ${transaction.confirmationStatus}); if (transactionDetails[i]) { transactionDetails[i].transaction.message.instructions.forEach((inst, n) => { console.log( Instr ${n+1}: ${inst.programId.toString()}); }); } console.log(''); });
}; getTransactions(searchAddress, 5); Run node log.js. Grabs last 5 txs, shows sigs, times, programs. Limit 1000 max per call-paginate with 'before' sig for more.
Why code? Alerts on big outflows. Or track NFT mints. Expand it-add Discord webhooks. Game changer.
Trouble? "Rate limited"? Use QuickNode or Helius RPC-free tiers rock. Public ones throttle.
Export CSVs from Solscan. Spreadsheet magic for taxes.
Revoke approvals monthly. Wallets like Phantom have a button. Match mint addresses-logos fake.
Unknown tx? Pause. Inspect programs. Funds gone? New wallet, stat. Backup seeds first.
Cross check wallet UI vs explorer. Wallets simplify; explorers raw truth.
Big deposits? Note 'em. Airdrops vanish if not claimed right.
| Fee Type | Typical Amount | When? |
|---|---|---|
| Base | 0.000005 SOL | Every tx |
| Priority | 0.0001-0.001 SOL | Congested network |
| Compute | Variable, k units | Complex instructions |
That's it. Fees low, but stack up on spam.
Tx failed but fee deducted? Normal-blockhash expired or invalid instruction. Resend.
No token change on swap? Check inner txs-might've reverted mid way.
Stake not showing? Wait epoch (2-3 days). Find activation sig.
Script errors? Check RPC endpoint. Mainnet beta for live.
Sound familiar? Happens to everyone. Now you fix it fast.
One more: Multi sig or versioned txs? Explorers handle 'em, but code needs {maxSupportedTransactionVersion:0}.
