About this source
Bitwise BITB is the sole U.S. spot-Bitcoin ETF that publishes the actual custody addresses backing its share outstanding. Other spot-BTC ETFs (BlackRock IBIT, Fidelity FBTC, Grayscale GBTC, etc.) publish only Coinbase-Custody attestation totals without per-address disclosure. We ingest the 66 addresses Bitwise lists on bitbetf.com; addresses rebalance roughly monthly as the ETF creates and redeems shares.
How we got the data
Scraped via tools/scrape_bitwise_bitb.py from bitbetf.com's landing-page JSON, generic research User-Agent.
Why this confidence
Direct disclosure by the ETF issuer. ETF custody addresses are the cleanest possible attribution: a regulated entity publishing its own holdings under SEC oversight.
License & attribution
Operator publishes for transparency. We attribute to bitbetf.com on every row and retain the snapshot date so downstream consumers can pin a balance to an ETF rebalance.
Sample addresses
python tools/build_labels_db.py --update --only bitwise-bitb
to populate it.
