How to Look Up a Bitcoin Wallet
The BTC.PH Wallet Lookup queries mempool.space's public API to retrieve balance and transaction data for any Bitcoin address — including legacy P2PKH addresses starting with "1", P2SH addresses starting with "3", and modern Bech32 SegWit addresses starting with "bc1". No API key or account is required. Enter any public address to instantly see total received, total sent, current balance in BTC and USD, and the five most recent on-chain transactions.
This tool is useful for verifying that a transaction has been received, checking the balance of a cold wallet, or researching a known address. All data is public and available on the Bitcoin blockchain — nothing private is exposed. For large transaction monitoring, see the Exchange Inflow/Outflow tool, or check live Whale Alerts on the Dashboard.
