Boltz has suspended its swap services indefinitely due to a surge in automated attacks, believed to be using AI, while ensuring user funds remain secure.
Boltz, a non-custodial Bitcoin service, has indefinitely halted its swap operations following a rise in automated attacks that are suspected to involve artificial intelligence.
In an update, Boltz confirmed that its service would remain offline until further notice, noting that its API would still be available for processing refunds. Unilateral refunds will continue to operate independently of Boltz's infrastructure. The support team remains accessible, and they clarified that this decision is not in response to a specific incident.
The platform specializes in atomic swaps, facilitating transactions between the Bitcoin main network, Lightning Network, and Liquid Network.
The Boltz team reported encountering multiple attacks that exploited vulnerabilities over recent months. Although they managed to mitigate each attack, new vulnerabilities were discovered by attackers faster than the team could implement fixes.
"After conducting our security scans, we cannot safely reactivate Boltz Swaps, especially since we are facing active attacks from likely multiple skilled groups," the developers stated.
Importantly, Boltz assured users that their funds are secure, as the service does not hold customer assets; users keep control over their funds throughout the exchange process.
While the API will continue to facilitate refunds and customer support will remain operational, the team cautioned that swaps would not resume quickly.
"We are witnessing a significant paradigm shift for Bitcoin services operating on an open stack, necessitating careful analysis," Boltz added.
This incident follows a report from Blockaid, which estimated that crypto projects suffered losses of approximately $1.1 billion due to hacks in the first half of 2026, with the number of confirmed exploits reaching unprecedented levels.
