Boltz Founders Exit as Unnamed Bitcoin Group Agrees to Take Over Suspended Swap Service

Boltz said it suspended the service on Aug. 3 after AI-assisted attackers targeted it with increasing frequency, intensity and sophistication over several months. The company said several attacks succeeded and caused losses, but that user funds were never at risk because the service is non-custodial.

In its Aug. 3 outage notice, Boltz said attackers were iterating faster than its team could find and patch flaws. On Wednesday, it described itself as a bootstrapped five-person startup that lacked the resources to withstand the attacks over the long term.

Swaps Remain Offline

As of Wednesday, the Boltz web app still displayed “Swap Services Disabled.” The outage notice said the API remained available for cooperative refunds and that unilateral refunds did not depend on Boltz infrastructure. Boltz also said its support team remained reachable.

Boltz’s API documentation says clients use its REST API to query supported pairs and to create and monitor swaps. Its official software supports swaps involving Lightning, bitcoin and Liquid bitcoin; a broader reference library also lists RBTC, WBTC, USDT and USDC among supported currencies.

The documentation lists Aqua Wallet, Bull Bitcoin Mobile, Klever Wallet and Misty Breez as users of Boltz-related libraries. New swaps remained unavailable at the reporting cutoff.
