Wallet and transaction analysis
Make sense of onchain activity.
Analyze a crypto wallet address or explain a transaction. Explore assets, transaction history, and public risk signals on Ethereum and Base, with source-cited AI analysis.
More tools
Go beyond a single lookup.
Check a balance change
My balance changed. Does the activity explain it?
Choose an address, ETH or a token, and a period. Compare the opening and closing balances with the recorded changes to see what adds up—and what doesn’t.
Checks a selected period, not lifetime profit.
Find assets across wallets
Which of my wallets holds this token?
Add the public addresses you use. Search by asset to see which wallets hold it and the balance recorded in each, without opening several explorers.

Watch for a new change
Has a transfer arrived, or has the balance changed?
Choose an address, asset and minimum change. Get an on-page alert when a periodic check finds a matching balance change or token transfer.
Checks run only while this tab is open and visible.
