The Bitcoin Live Wallets page shows on-chain Bitcoin holdings and recent custody movements for US spot ETF funds — BlackRock's IBIT, Fidelity's FBTC, ARK's ARKB, Bitwise's BITB, and all other major ETFs. Every ETF custodian holds Bitcoin in known wallet clusters on the public blockchain. Bitcoin Live identifies those addresses and tracks them in real time.
The Wallets page lets you verify the ETF custody data you see on the Flows page. If IBIT reports a $500 million inflow for the day, you can check the on-chain Esplora data to confirm the corresponding Bitcoin was actually deposited into BlackRock's custodial addresses. Don't trust the ETF issuer's reports alone — verify the on-chain record.
Each ETF cluster page shows total on-chain BTC holdings, recent transaction history with timestamps and USD values, and a running balance over time. You can also look up any Bitcoin address directly to see its balance, transaction history, and whether it appears to be affiliated with any known fund.
On-chain data is the most transparent layer of Bitcoin money flow. Unlike exchange order flow (which shows aggregate taker activity) or ETF flow data (which comes from issuer-reported NAV filings), on-chain data is publicly verifiable by anyone with an internet connection. Bitcoin Live sources its on-chain data from the mempool.space Esplora API.
