Summary
- Boltz has indefinitely halted its Bitcoin swap service.
- The firm cites the rapid pace of AI-enabled attacks as the reason for the suspension.
- Boltz assures that user funds are secure as it operates on a non-custodial basis.
Boltz, a non-custodial Bitcoin swap service, has announced the indefinite suspension of its Bitcoin swap operations due to a surge in AI-assisted cyber attacks that have compromised its ability to operate securely.
In a series of updates posted on X, the company indicated that swaps will remain disabled "until further notice," without providing a timeline for resuming service.
Boltz stated, “We can't give an ETA as of this time, but will provide an update once we know more,” in one of their posts on social media.
The platform enables users to exchange Bitcoin between the Lightning Network and the blockchain’s base layer while retaining control of their funds. Although Boltz has not disclosed specific transaction volumes, it currently manages approximately $262,000 in total value locked as reported by DeFiLlama.
Boltz emphasized that since users maintain control over their assets during transactions, "no user funds were ever at risk."

The company clarified, "This is not a reaction to a single event," adding that there has been a consistent increase in automated, AI-driven probing of their systems. They have faced multiple exploits, each contained, but the frequency of attacks has escalated, indicating that attackers are now moving faster than their team can patch vulnerabilities.
Due to the recent uptick in these attacks, Boltz concluded that it could no longer safely operate its swap services. "After reviewing our recent security scans, we cannot responsibly re-enable Boltz swaps, especially as we are being actively targeted by what appear to be multiple resourceful groups while we race to deploy fixes," the company noted.
Despite the suspension, Boltz's API is still operational for processing cooperative refunds, and unilateral refunds are functioning independently of Boltz’s infrastructure. Customer support services remain available as well.
Boltz suggested that these cyber threats reflect a significant shift in the landscape for Bitcoin infrastructure providers. "What we are witnessing is a major paradigm shift for Bitcoin services operating on an open-source stack, which requires thorough analysis," they stated. "Do not expect swap services to resume shortly."
This announcement coincides with ongoing discussions in the cryptocurrency sector about the evolving role of AI in cyberattacks.
On Tuesday, Ledger’s CTO Charles Guillemet warned that AI technologies enable attackers to rapidly scan code for vulnerabilities, while defenders are increasingly turning to AI to identify these flaws before they can be exploited. This commentary arose amidst the growing repercussions from the Coldcard exploit, which has led to losses approaching $130 million.
