Frequently Asked Questions
What information can I find using an ETH explorer?
You can discover transaction details, wallet balances, smart contract code, gas fees, block information, and network statistics.
How do I verify if a transaction is confirmed?
Search the transaction hash in the explorer and check for the number of block confirmations. Typically 12-30 confirmations are considered secure.
Can I track ERC-20 token transfers?
Yes, all reputable Ethereum explorers support ERC-20 token tracking, displaying balances and transfer history for any compliant token.
What's the difference between a contract address and wallet address?
Contract addresses execute code when receiving transactions, while wallet addresses simply send/receive ETH and tokens. Explorers clearly distinguish between them.
How often is the blockchain data updated?
Most explorers update in real-time as new blocks are added to the Ethereum chain (approximately every 12-14 seconds).
