Reading the Solana Explorer

Block explorers are the most direct way to see what the Solana network is doing in real time. Two popular options are Solscan and Solana FM. Both show the same underlying data; the interfaces differ slightly.

Finding a transaction

Every transaction has a unique signature — a long string of characters. Paste it into the explorer search bar to see its details. You will find:

Status — whether the transaction succeeded or failed
Block time — when it was processed
Fee — the SOL paid for compute
Instructions — the individual operations within the transaction

A single user action (like swapping tokens) often involves multiple instructions bundled together.

Understanding accounts

Click any account address to see its balance, token holdings, and recent activity. Solana accounts are not just wallets — programs also have accounts that store data.

Look for:

Owner — the program that controls the account
Lamports — the SOL balance (1 SOL = 1,000,000,000 lamports)
Data — for program accounts, the stored bytes

Reading program interactions

When a transaction involves a decentralised exchange or NFT marketplace, the instructions section shows which programs were called. Common program IDs appear often enough that explorers label them (e.g., “Token Program,” “System Program”).

If you are debugging a failed transaction, the logs tab shows program output and error messages. Failed transactions still cost fees because validators performed compute work.

Tokens and NFTs

The tokens tab on an account page lists all SPL tokens held. NFTs appear here too, often with metadata links. Click through to see the mint address and current holders.

Practice exercise

Pick a recent block from the explorer homepage. Open three random transactions and identify: the signer, the fee, the number of instructions, and whether each succeeded. This builds intuition faster than reading documentation alone.

For a guided walkthrough, our Network Orientation Session includes a live explorer demonstration.
