Quantum exposure Reuse-exposed

P2WSH · reuse-exposed

P2WSH addresses hide the pubkey behind a SHA-256 + RIPEMD-160 hash UNTIL the first outgoing spend, which reveals it in the signature script or witness data. This address has been spent from, so its pubkey is permanently on chain. Every subsequent UTXO at this address is just as exposed as the moment of first spend.

First revealed at block 905,805 on 2025-07-16 (p2wsh_redeem_reveal).

What we know about this address 6 findings

Bitfinex (cold wallet, unconfirmed)

OKLink labels this 'Bitfinex. Cold Wallet_1', but the attribution appears to propagate transitively from an upstream sender (the 2024-12-31 30,000 BTC inflow source) that Arkham's 2026 research explicitly lists as Unattributed. Bitfinex's own published wallets.txt does not include this address. Listed at low confidence pending corroboration. Provenance: LOW, single label-database hit with weak chain-of-custody.
