Boltz has suspended its Bitcoin swap service indefinitely, saying a surge in AI-assisted attacks has left it unable to continue operating safely.
In a series of posts on X on Monday, the company said swaps are disabled "until further notice" and that it cannot provide an estimate for when the service will return.
Because users retain control of their assets throughout the process, Boltz said "no user funds were ever at risk."
Boltz Swap Services are currently unavailable until further notice. We can't give an ETA as of this time, but will provide an update once we know more
Boltz said the pace of attacks accelerated over the past few days, leading it to conclude it could no longer safely operate its swap service.
"After reviewing the results of our own 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 wrote.
The company said its API remains available to process cooperative refunds, unilateral refunds continue to work because they do not depend on Boltz's infrastructure, and customer support remains available.
Boltz argued the attacks reflect a broader change facing Bitcoin infrastructure operators.
"What we are seeing is a major paradigm shift for Bitcoin services operating on an open source stack, and it needs careful analysis," the company wrote. "Do not expect swap services to resume shortly."
The announcement comes as the cryptocurrency industry grapples with how AI is changing cyberattacks.
