P2WPKH · reuse-exposed

P2WPKH 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 916,157 on 2025-09-24 (input_spend).

What we know about this address 6 findings

Deribit (Coinbase Prime Custody, unconfirmed)

Following Coinbase's August-2025 acquisition of Deribit, two label databases (OKLink, Spark.money) tagged this address as a Deribit cold wallet under Coinbase Prime Custody. The attribution did not survive adversarial verification: no first-party Deribit/Coinbase disclosure names the address, and the 'Coinbase Prime Custody' tag conflicts with Deribit's documented Copper Clearloop custodian (per BitGo/Copper announcements through Dec 2025). Listed at low confidence pending primary disclosure. Provenance: LOW, label-database hit contradicted by documented custody arrangement.
