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.
Getting Started
Navigate to solscan.io. No account or wallet connection is needed for basic functionality. The search bar at the top accepts:
- Transaction signatures: Paste a transaction hash to see its details
- Wallet addresses: View any wallet's balances, transaction history, and token holdings
- Token mint addresses: See token details, holders, supply, and transfer history
- Block numbers: View specific blocks and their transactions
- Domain names: Solscan resolves .sol domains (SNS) to their wallet addresses
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.
Reading Transactions
Transaction analysis is the most common use of a block explorer. Here's how to read a Solscan transaction page.
Transaction Overview
When you search a transaction signature, the overview shows:
- Status: Success or failed (with error code if failed)
- Block: The slot number where the transaction was included
- Timestamp: When the transaction was processed
- Fee: The transaction fee paid (typically 0.000005 SOL for a simple transfer, higher for complex transactions)
- Signer(s): The wallet(s) that signed the transaction
SOL Balance Changes
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.
Token Balance Changes
This is where Solscan shines for DeFi users. When you perform a swap on Jupiter or Raydium, the token balance changes section shows:
- Which tokens left your wallet (and how many)
- Which tokens entered your wallet (and how many)
- Any intermediate tokens involved in multi-hop routes
- Fee amounts taken by protocols
This is invaluable for verifying you received the correct amount after a swap, or for tracking exactly what happened in a complex DeFi transaction.
Instruction Details
Every Solana transaction contains one or more instructions — the actual operations being performed. Solscan decodes these into readable format:
- System Program: SOL transfers, account creation
- Token Program: Token transfers, approvals, mints, burns
- Associated Token Account Program: Creating token accounts
- DeFi protocols: Swap instructions, liquidity additions, lending operations
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.
Transaction Logs
The logs tab shows the program execution logs — useful for developers debugging failed transactions. Common patterns to look for:
- "Instruction: Transfer": A token or SOL transfer was executed
- "Program log: Error": Something went wrong — the message usually explains what
- "Invoke [program_id]": A cross-program invocation (one program calling another)
- Compute units consumed: How much computational budget the transaction used
Tracking Wallets
Wallet analysis is Solscan's second most common use case. Search any Solana address to see a comprehensive dashboard.
Portfolio Overview
The wallet page shows:
- SOL balance: Current SOL holdings
- Token balances: All SPL tokens held, with current values
- NFTs: All NFTs in the wallet, displayed with images
- Total portfolio value: Estimated USD value across all holdings
- Staking: Any staked SOL positions and their validators
Transaction History
Scroll down to see the wallet's full transaction history. You can filter by:
- All transactions: Everything the wallet has done
- SOL transfers: Only SOL movements
- Token transfers: Only SPL token movements
- DeFi activity: Swaps, liquidity, lending
- NFT activity: Mints, transfers, sales
Each transaction shows the timestamp, type, counterparty, and amounts. Click any transaction to see its full details.
Token Accounts
Solana requires a separate "token account" for each SPL token a wallet holds. The token accounts tab shows:
- All active token accounts
- Token balances and values
- Token account addresses (useful for technical operations)
- Empty token accounts that can be closed to recover rent SOL
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.
Stake Accounts
If the wallet has staked SOL, this tab shows:
- Active stake accounts and their delegated validators
- Stake amounts and activation epochs
- Rewards earned per epoch
- Deactivating/withdrawable stake
Analyzing Tokens
Token analysis is critical before buying any Solana token. Here's what to look for on a token's Solscan page.
Token Overview
Search a token's mint address to see:
- Name and symbol: As set in the token's metadata
- Current price: From DEX data
- Market cap: Calculated from price and circulating supply
- Total supply: Total tokens minted
- Decimals: Number of decimal places (important for understanding amounts)
- Mint authority: Who can mint more tokens (if this is still active, new supply can be created)
- Freeze authority: Who can freeze token accounts (a significant centralization risk if active)
Key Security Checks
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.
Holder Analysis
The holders tab shows:
- Top holders ranked by balance
- Percentage of supply each holder controls
- Holder wallet addresses (clickable for further investigation)
- Total number of unique holders
What to look for:
- A healthy token has thousands of holders with no single wallet controlling more than 5-10%
- Exclude known liquidity pool addresses and protocol treasuries from your concentration analysis
- A rapidly increasing holder count suggests growing adoption; a declining count may signal selling pressure
Transfer History
The transfers tab shows all token movements chronologically. This is useful for:
- Tracking large whale movements
- Identifying sell pressure (large transfers to DEX pools)
- Verifying claimed token burns (transfers to burn addresses)
- Monitoring team/insider wallet activity
Checking Validators
Solscan includes a validator directory that's useful for stakers choosing where to delegate.
Validator List
Navigate to the Validators section to see:
- All active validators ranked by stake
- Commission rates (what percentage validators keep from staking rewards)
- Uptime and skip rates (how reliable each validator is)
- Vote account addresses
- Data center locations and concentration
What to Look For in a Validator
- Commission: 0-10% is typical. Lower is better for delegators, but 0% validators may not be sustainable
- Skip rate: Lower is better. High skip rates mean the validator is missing blocks, reducing your rewards
- Stake concentration: Avoid validators with too much stake — it's better for network health to delegate to smaller, reliable validators
- Data center diversity: Validators in less common data centers contribute to network decentralization
For a deeper guide on validator selection, see our how to choose a Solana validator article.
DeFi Analytics
Solscan's DeFi section provides aggregate analytics across the Solana DeFi ecosystem.
DEX Activity
View trading volumes across major Solana DEXes:
- Daily and historical volume charts
- Top trading pairs by volume
- DEX market share comparisons
- Individual pool statistics
Token Trending
Solscan tracks trending tokens based on:
- Transaction count (most active)
- Unique wallets interacting
- Volume changes
- New token launches
This can surface tokens gaining traction before they appear on other tracking platforms.
Using the Solscan API
For developers and power users, Solscan offers a REST API for programmatic access to on-chain data.
API Access
Solscan provides both free and paid API tiers:
- Free tier: Rate-limited, suitable for personal projects and testing
- Pro tier: Higher rate limits, additional endpoints, priority support
Common API Use Cases
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.
Example: Fetching Account Tokens
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 vs. Other Solana Explorers
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.

Power User Tips
Bookmark Wallet Pages
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.
Use Browser Extensions
Several browser extensions integrate with Solscan to enhance your workflow:
- Auto-link wallet addresses on Twitter/X to their Solscan pages
- Add Solscan lookup buttons to wallet interfaces
- Show quick portfolio summaries in browser popups
Export Transaction History
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.
Monitor Programs
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.
Check Token Metadata
Before interacting with a new token, check its Solscan page to verify:
- The mint address matches what's listed on official sources
- Mint and freeze authorities are appropriately configured
- The token has reasonable holder distribution
- Transaction history shows organic activity (not just wash trading)
Common Tasks Quick Reference
| 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 |

Wrapping Up
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.
Pair Solscan with SolanaFM for the best transaction decoding, and the official Solana Explorer when you need raw developer-oriented data. Together, these three explorers give you complete visibility into everything happening on Solana.
