Investigations into the Coldcard exploit face technical discrepancies when quantifying the total theft. A detailed report on the hardware wallet exploit points to estimates ranging between 1,432 and 1,816 extracted bitcoins across the network.
Unlike a breach of a centralized exchange, this self-custody attack lacks a unified registry of compromised accounts. Analysts rely heavily on individual user reports to map out the scale of the security event. The dispersion of stolen funds complicates definitive tracking. Portions of these assets have been mobilized onchain, revealing transfers to crypto mixers in attempts to obfuscate the transaction origins and launder the digital assets.
Tracking onchain methodologies
Galaxy Research established a high-confidence minimum of 1,730 Bitcoin confirmed as of Tuesday, according to Alex Thorn. This figure emerges from corroborating victim claims against the movements recorded on the blockchain network. Galaxy’s methodology combines 450 directly verified bitcoins with another 730 identified through associated cluster patterns. The firm is withholding additional metrics from its counts until securing sufficient validation from the affected parties.
In contrast, CryptoQuant applies a stricter criterion based exclusively on public statements. Its metrics dashboard and onchain tracking data metrics set the confirmed losses at 1,432 BTC extracted from wallets affected by the breach.
Julio Moreno, head of research at CryptoQuant, argues that identifying victims solely by onchain behaviors could generate false positives. This conservative approach seeks to prevent artificial inflation in the balance of compromised funds.
The debate over methodologies highlights the vulnerabilities of physical custody. The metrics of the event expose lessons about cold storage against attack vectors undetected during initial security audits of the hardware devices.
Structural impact on compromised addresses
TRM Labs aligns with the upper range presented by Galaxy Research. The intelligence firm determined that the attackers drained 1,816 BTC across four waves, impacting more than 5,200 distinct addresses since the breach began. Ari Redbord, global head of policy at TRM Labs, projects that the loss estimate will continue to climb before stabilizing. The reliance on manual reporting delays the consolidation of information regarding the affected wallets.
Sorry I have no current have no plans to monitor or trace the ColdCard incident.

My time is focused on ecosystems who value my work whereas Bitcoin maxis are not donors or supporters so I have less obligation to help.

Other industry players have chosen to remain on the sidelines. While Chainalysis has not executed an independent tally, the blockchain investigator ZachXBT dismissed monitoring the event and its respective metrics publicly on his social media channels.
Traceability in decentralized environments imposes technical limits on forensic audits. Dealing with individual entities means investigators face privacy barriers that prevent them from consolidating an automatic inventory of the compromised private keys.
The consolidation of the final stolen amount will depend on the victims’ willingness to reveal their public addresses. Without this cooperation, blockchain analysts will continue operating within statistical margins of error.
The contrast between the figures reflects the tension between documentary precision and heuristic analysis. Both approaches are necessary to understand the complete architecture of a fragmented capital extraction in the decentralized ecosystem.
Until a consolidated forensic verdict is issued, the hardware wallet market operates with partial information. The community maintains scrutiny over outgoing transactions to identify potential bottlenecks in the stolen liquidity pools.
