Every Solana user needs a block explorer. Whether you're checking if a transaction landed, investigating a wallet, researching a token before buying, or debugging a failed swap — a block explorer is your window into what's actually happening on-chain.
Solscan has become the most widely used Solana block explorer for good reason: it combines clean design with deep on-chain data, token analytics, DeFi tracking, and an API that developers rely on daily. It's what Etherscan is to Ethereum, but with features tailored to Solana's unique architecture.
This guide covers everything Solscan can do — from basic transaction lookups to advanced analytics that most users never discover.
Updated May 2026: Solscan's UI got a refresh in early 2026, the Pro tier hit price parity with several alternatives, and a new "AI Insights" panel surfaces wallet behavior summaries. We've added these to the relevant sections, plus a new FAQ and a comparison to other Solana explorers (SolanaFM, OKLink, Solana Beach).
Navigate to solscan.io. No account or wallet connection is needed for basic functionality. The search bar at the top accepts:
Pro tip: Solscan also accepts program IDs. If you're a developer, you can search for any Solana program to see its transaction activity and interaction patterns.
Transaction analysis is the most common use of a block explorer. Here's how to read a Solscan transaction page.
When you search a transaction signature, the overview shows:
This section shows exactly how much SOL moved between accounts. For a simple transfer, you'll see the sender's balance decrease and the receiver's increase. For complex transactions (DeFi swaps, NFT mints), multiple accounts may show balance changes — including program accounts, fee recipients, and intermediaries.

Open the KOL TrackerThis is where Solscan shines for DeFi users. When you perform a swap on Jupiter or Raydium, the token balance changes section shows:
This is invaluable for verifying you received the correct amount after a swap, or for tracking exactly what happened in a complex DeFi transaction.
Every Solana transaction contains one or more instructions — the actual operations being performed. Solscan decodes these into readable format:
For known programs, Solscan shows human-readable instruction names (e.g., "Swap" instead of raw program data). For unknown programs, you'll see raw instruction data that requires technical knowledge to interpret. Some of that raw data is deliberate — our guide to Solana inscription tokens and on-chain data storage explains how projects write arbitrary content directly into transactions.
The logs tab shows the program execution logs — useful for developers debugging failed transactions. Common patterns to look for:
Wallet analysis is Solscan's second most common use case. Search any Solana address to see a comprehensive dashboard.
The wallet page shows:
Scroll down to see the wallet's full transaction history. You can filter by:
Each transaction shows the timestamp, type, counterparty, and amounts. Click any transaction to see its full details.
Solana requires a separate "token account" for each SPL token a wallet holds. The token accounts tab shows:
Pro tip: If you have dozens of empty token accounts from tokens you've fully sold, you can close them to recover ~0.002 SOL each. Solscan shows these clearly so you know which accounts are empty. Our step-by-step guide on how to recover lost SOL from empty token accounts covers the safest way to close them in bulk.
If the wallet has staked SOL, this tab shows:
Token analysis is critical before buying any Solana token. Here's what to look for on a token's Solscan page.
Search a token's mint address to see:
When evaluating a token on Solscan, check these fields:
Mint authority: If this shows an active address (not null/disabled), the token creator can mint unlimited new tokens, diluting holders. For legitimate projects, mint authority is typically revoked after initial supply creation.
Freeze authority: If active, the authority holder can freeze any wallet's tokens, preventing transfers or sales. This is a red flag for most tokens unless it's a regulated stablecoin (like USDC, which legitimately uses freeze authority for compliance).
Supply concentration: Check the "Holders" tab to see how supply is distributed. If the top 10 wallets hold 80%+ of supply, the token is highly concentrated and vulnerable to dumps.
For deeper token security analysis, pair Solscan with dedicated scanners — see our guide to the best Solana token scanners.
The holders tab shows:
What to look for:
The transfers tab shows all token movements chronologically. This is useful for:
Solscan includes a validator directory that's useful for stakers choosing where to delegate.
Navigate to the Validators section to see:

Solscan tracks trending tokens based on:
This can surface tokens gaining traction before they appear on other tracking platforms.
For developers and power users, Solscan offers a REST API for programmatic access to on-chain data.
Solscan provides both free and paid API tiers:
Transaction monitoring: Poll for new transactions on a specific wallet to build alerts or accounting systems.
Token analytics: Fetch holder counts, supply data, and transfer history for portfolio tracking or research tools.
Wallet analysis: Build custom dashboards that pull wallet balances and activity.
NFT tracking: Monitor NFT transfers and marketplace activity programmatically.
GET https://pro-api.solscan.io/v2/account/tokens?address=WALLET_ADDRESS
Returns all token holdings for a wallet with balances, prices, and token metadata. Useful for building portfolio trackers or wallet analytics tools.
The API documentation is available at pro-api.solscan.io with interactive examples and endpoint references.
Solscan isn't the only option. Here's how it compares to alternatives:
The official Solana Explorer is maintained by the Solana Foundation. It's more minimal than Solscan — focused on transaction details, account data, and program information. It's excellent for developers who want raw data without the analytics layer, but less useful for casual users who want to understand what a transaction did.
Choose Solana Explorer when: You need raw account data, program deployment info, or validator details from the official source.
SolanaFM is another popular explorer with a focus on transaction decoding and labeling. SolanaFM often provides more human-readable transaction descriptions than Solscan, especially for complex DeFi transactions.
Choose SolanaFM when: You want the most readable transaction breakdowns, especially for complex multi-instruction transactions. Our SolanaFM block explorer guide for beginners walks through its interface and decoding features.
For a head-to-head ranking of all three, see our best Solana block explorers comparison.
| Feature | Solscan | Solana Explorer | SolanaFM |
|---|---|---|---|
| Transaction decoding | Good | Basic | Excellent |
| Token analytics | Excellent | Basic | Good |
| Holder analysis | Yes | No | Yes |
| DeFi analytics | Yes | No | Limited |
| API access | Yes (free + paid) | Limited | Yes |
| NFT display | Good | Basic | Good |
| Validator info | Yes | Yes | Limited |
| User interface | Clean, intuitive | Minimal, technical | Modern, detailed |
| Best for | General use, token research | Developers, raw data | Transaction analysis |
If you regularly monitor specific wallets (your own, whale wallets, project treasuries), bookmark their Solscan pages. Solscan URLs are stable — solscan.io/account/ADDRESS always resolves to the current state.
Several browser extensions integrate with Solscan to enhance your workflow:
Solscan Pro allows CSV exports of transaction history — essential for tax reporting and accounting. Export by date range and filter by transaction type.
For dedicated tax tooling, see our Solana tax guide.
If you're tracking a specific protocol's activity, search its program ID on Solscan. The program page shows transaction volume over time, which can indicate growing or declining usage — useful for research before investing in a protocol's token.
Before interacting with a new token, check its Solscan page to verify:
| Task | Where to Find It |
|---|---|
| Check if a transaction succeeded | Search tx signature, check Status field |
| See what tokens you received in a swap | Search tx signature, check Token Balance Changes |
| Find a wallet's SOL balance | Search wallet address, see Portfolio Overview |
| Check who holds the most of a token | Search token mint, click Holders tab |
| Verify a token's supply | Search token mint, check Total Supply and Mint Authority |
| Find your staking rewards | Search your wallet, check Stake Accounts tab |
| Track a whale wallet's trades | Search whale address, filter by Token Transfers |
| Check validator performance | Navigate to Validators section |
| Export transaction history | Solscan Pro, CSV export feature |
Yes — the core block-explorer features (transaction lookup, wallet inspection, token search, holders, validators) are free with no signup required. Solscan Pro unlocks CSV exports, deeper analytics, the priority API tier, and the AI Insights panel. For casual use, free is plenty.
For deeper KOL-level analysis (which wallets are early on a token, who's coordinating buys), Solscan won't tell you — that's what our KOL tracker and deployer hunter are for.
Three checks: (1) Mint authority — should be null for established tokens (means no one can mint more); (2) Freeze authority — should be null (means no one can freeze your tokens); (3) Top holders concentration — if the top 10 holders own >50% of supply (excluding the LP pool), the token is rug-prone. None of these guarantees safety, but each red flag eliminates a percentage of obvious scams.
Most likely the transaction had multiple inner instructions and only some failed. Solscan shows the top-level status, but if a swap failed but a fee transfer succeeded, your balance will reflect partial activity. Look at the Inner Instructions section to see what actually executed.
Solscan has a paid API (Pro tier and above), but it's rate-limited and doesn't expose the live KOL/deployer enrichment we provide. For Solana-native intelligence (KOL trades, deployer history, token marketcap, real-time DEX firehose), our API is purpose-built — see the endpoint reference.
Solscan is one of those tools that every Solana user interacts with, but few use to its full potential. Beyond basic transaction lookups, it offers token security analysis, holder distribution data, DeFi analytics, validator information, and a developer API that powers countless Solana applications.
For most users, the key habits are: verify every transaction before and after it lands, check token mint/freeze authorities before buying anything new, and monitor your own wallet activity regularly to catch unauthorized transactions early.
For the chart and liquidity side Solscan doesn't cover, see our DEXScreener guide. Building instead of browsing? Our Helius guide covers the RPC/API infrastructure layer.
Pair Solscan with SolanaFM for the best transaction decoding, and the official Solana Explorer when you need raw developer-oriented data. For tracking which wallets are smart-money on a given token (a layer Solscan doesn't surface), use our KOL tracker. Together, these tools give you complete visibility into Solana — not just at the transaction level, but at the trader-behavior level.
