What is a Block Explorer?
A block explorer is a web-based tool that lets you search, browse, and analyze data on a blockchain. It's like a search engine for blockchain data -- you can look up any transaction, block, or wallet address to see what happened on-chain.
What Can You Do with a Block Explorer?
- Look up transactions: Enter a transaction hash to see its status (success/failed), the sender, receiver, amount transferred, gas fees paid, and more.
- Browse blocks: View the contents of any block, including all the transactions it contains and when it was mined.
- Check addresses: See the balance and transaction history of any wallet address.
- Track tokens: View ERC-20 token transfers, contract interactions, and token holder information.
- Monitor gas prices: Check current gas fees to time your transactions for lower costs.
How to Use Omniscanner
- Search by block number: Type a block number in the search bar to jump directly to that block's detail page.
- Search by transaction hash: Paste a transaction hash (0x...) to view the full transaction details.
- Search by address: Enter a wallet or contract address to see its activity.
- Switch networks: Use the network selector in the top-right corner to explore different blockchains.
Why Omniscanner is Different
Most block explorers only support one chain (Etherscan for Ethereum, Solscan for Solana). Omniscanner supports 147+ blockchains in a single interface, including:
- EVM chains (Ethereum, Base, Arbitrum, Polygon, etc.)
- Solana (SVM)
- Bitcoin and UTXO chains
- Cosmos SDK chains
- Substrate/Polkadot chains
- And many more
This means you can explore any supported blockchain without switching between different websites.
