Non-custodial Bitcoin service Boltz has suspended swaps indefinitely due to an increase in automated attacks, allegedly using AI.
Update: Boltz will stay disabled until further notice.

Our API remains available to process refunds cooperatively. In any case, unilateral refunds will work, as they do not depend on our infrastructure.
Our support team stays reachable.

Boltz enables atomic swaps. The service supports transfers between the Bitcoin mainnet, the Lightning Network, and the Liquid Network.
According to the team, in recent months they have faced several attacks exploiting vulnerabilities. Each was contained, but malicious actors began finding new vectors faster than Boltz's small team could patch them.
"After reviewing the results of our own security scans, we cannot responsibly re-enable Boltz Swaps, especially given that we are being actively attacked, likely by several well-resourced groups," the developers stated.
Boltz emphasized that user funds were not at risk. The service does not store client assets: with a non-custodial model, users retain control of their funds during the exchange.
Boltz's API will remain available for processing refunds, and the support service will continue operating. However, the team warned not to expect swaps to resume soon.
"We are witnessing a major paradigm shift for Bitcoin services operating on an open stack, and this requires careful analysis," Boltz stated.
Earlier, Vitalik Buterin named code verification and bug detection as one of the promising application scenarios for AI in Ethereum.
Recall that in July, Blockaid analysts estimated that in the first half of 2026, crypto projects lost about $1.1 billion due to hacks, and the number of confirmed exploits set a record for a six-month period.
