QuadrigaCX cold wallet addresses
QuadrigaCX, a Canadian exchange, collapsed in early 2019 after the reported death of its founder, who was described as the only person able to access the exchange's cold storage. Court-appointed monitor Ernst & Young reported that it had identified six bitcoin cold wallets, that five had held no bitcoin since April 2018, and that the sixth appeared to have been used only to route funds into the exchange's hot wallet. Independent blockchain analysis published a set of addresses said to correspond to that cold storage. Several of those addresses saw movement again in December 2022, which the monitor said was not authorised by it.

What is — and is not — established
The five cold-wallet addresses were identified by a Reddit analyst ("Decoze") and republished by CoinDesk — that is third-party clustering, not the monitor's own address list, which could not be fetched from EY's document centre this session, so the mapping to EY's "Identified Bitcoin Cold Wallets" is inference. Only 3N8auHdN9rtmHDHqNnXK4eWhfukBAQcve1 is described as appearing in a court affidavit, and that description is CoinDesk's. On-chain these addresses are drained (funded and spent totals match), so "empty cold wallets" is literally accurate; dormancy is flagged because renewed movement on them has previously been newsworthy.
