Real-time inflow / outflow signals on tagged Bitcoin addresses. Exchange and custodian in/out flow are the headline use case for traders, but the dataset is broader: every known address we can find or your provide a label for: mining pools, OFAC-sanctioned wallets, lost-coin cold storage, famous holders, your HODL stash the works.

What it'll cover

• Exchange clusters: Coinbase, Binance, Kraken, Bitfinex, OKX, Bitstamp, Gemini, etc. Hot wallets, cold storage, deposit-address ranges.
• Custodians: Anchorage, BitGo, Fidelity, BlackRock-IBIT, GBTC, the spot-ETF custodians.
• Mining pools: Foundry, AntPool, F2Pool, ViaBTC, Binance Pool, Luxor, etc. Coinbase reward addresses.
• Lost coins: Mt. Gox cold wallet, Patoshi pattern blocks, FBI-seized wallets, dormant Satoshi-era coins.
• Sanctioned wallets: OFAC SDN list addresses (Tornado Cash, Lazarus Group, etc.).
• User-supplied tags: clients can pass us their own address sets to monitor without exposing them publicly.

How it'll work

• Push real-time inflow / outflow events as they enter the mempool and/or confirm
