Non-custodial Bitcoin swap provider Boltz has suspended all swaps indefinitely. The team says attackers are finding vulnerabilities faster than they can patch them. The move leaves users of the platform without a way to exchange Bitcoin for Lightning Network assets or other cryptocurrencies through Boltz's service.
Why Boltz pulled the plug
Boltz is a non-custodial swap provider — meaning users never hand over control of their coins. That design is supposed to reduce trust risk. But it doesn't eliminate technical risk. According to the team, attackers have been consistently discovering flaws in the swap logic or infrastructure before fixes could be rolled out. The gap between discovery and patch kept shrinking until the team decided the only safe move was to stop entirely.
The company didn't specify how many vulnerabilities were found or whether any funds were lost. But the indefinite suspension suggests the problem isn't a single bug — it's a pattern.
What users saw
On the Boltz website and app, swap options are now grayed out. Existing pending swaps are being processed, but no new ones can be started. The team posted a brief notice on their official channels: swaps are suspended until further notice. No timeline was given.
For users who had funds in transit, Boltz says those swaps will complete normally. The non-custodial nature means the team can't freeze or redirect funds — but it also means users are responsible for their own transaction monitoring.
A losing race
Boltz's situation highlights a brutal reality for smaller crypto projects: security is a constant arms race, and the attackers often have the advantage. They can probe at will, while the team has to divide time between building features, maintaining infrastructure, and patching holes. When the discovery rate outpaces the fix rate, the only rational choice is to stop the service.
It's not the first time a swap provider has hit this wall. But Boltz's non-custodial model means the damage is limited — no central wallet to drain, no user funds pooled in a hot wallet. Still, the suspension is a blow to users who relied on the service for quick, trust-minimized swaps.
No timeline for return
Boltz hasn't said when — or if — swaps will resume. The team is working on a more robust architecture, but they're not promising a date. For now, users looking to swap Bitcoin for Lightning assets will need to find alternatives. The question is whether Boltz can rebuild fast enough to stay relevant, or whether the attackers have already won.
