UPDATE ON THE FUTURE OF BOLTZ 📢
Over the past couple of months, AI-assisted attackers have been targeting Boltz with increasing frequency, intensity and sophistication. Several of these attacks succeeded, but because Boltz is non-custodial, user funds were never at risk. The entirety of the risk was ours, and as a result of the losses incurred, on August 3rd we made the difficult decision to suspend the service to prevent further damage.
While working on a plan to bring Boltz back over the past days, we had to accept one painful insight: as a bootstrapped five-person startup, we simply don't have the resources to withstand the current level of attacks in the long run.
Today, we are happy to announce that a group of veteran Bitcoiners came forward to help, bringing the capital and engineering power the project needs. They have agreed to take over Boltz and continue the service. Work to find and fix the vulnerabilities is already under way, with the goal of bringing swaps back as soon as possible.
As we want to give them the freedom to introduce themselves in their own time, we are not attaching any names today.
All original founders of Boltz have stepped down from the company, effective immediately. None of us will have any formal or authoritative role with the Boltz project going forward, and any future open-source participation by us is strictly on a voluntary basis.
We are grateful for the community's support all these years, for the patience and understanding of our integrators affected by the disruption of our service, and to everyone who reached out offering support over the past week.
It was a hell of a ride, and we are proud of our contributions to the Bitcoin ecosystem.
Godspeed to the new Boltz team as they navigate these perilous times. We know Boltz is in good hands.
- Kilian, Michael & Karl

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.
To be clear: this is not a response to a single incident. Over the past months we have seen a steady rise in automated, AI-assisted probing of our infrastructure, and we have dealt with several exploits. Each was contained, but the pattern is clear: attackers now iterate faster than a team our size can find and patch. In the past few days alone we saw a drastic acceleration, and we do not believe this asymmetry will reverse. 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.
What we are seeing is a major paradigm shift for Bitcoin services operating on an open source stack, and it needs careful analysis. Do not expect swap services to resume shortly.
To be explicit: no user funds were ever at risk. Boltz is non-custodial by design. And as a fully bootstrapped company, the losses were ours alone.
We don't know yet how things will continue from here, but we'll keep you posted as soon as we have had the time to catch our breath and make a decision 🙏

Update: USDT0 has temporarily increased Arbitrum outbound transfer times as a precaution following recent events.
As a result, Boltz swaps to non-Arbitrum USDT rails now take ~22 mins.
You can monitor progress via the “Open Claim Transaction” link.

Boltz Mini has a bunch of publicly announced channels and is decently well connected. You are the first to report an issue with it: https://amboss.space/node/03e9c5157126b8049ad235bdade8db97a473b5760b34781b8c870bd2ba34dbfcf8?section=Channels
It must be some limit you are applying locally to your routing that makes the payment fail. Anyhow let's continue debugging this in the support ticket you opened.
And regarding node selection: it's dynamic and we don't plan to expose this. The node we assign to a swap should always work for you and you shouldn't have to care which node. Let's figure out why you can't route to Boltz Mini.

Good question! For full transparency:
In this scenario it can:
a) you used the same rescue key for all your swaps and then use the rescue key file on a different browser to scan your rescue key for refundable swaps
In these scenarios it can't:
b) you refund using the same browser (using local storage, not the rescue key file)
c) you download a new rescue key for every swap just like before which is the default behavior for privacy browsers on a fresh local storage (see https://x.com/kilrau/status/1899852590797488332)
For privacy-conscious users, option c) avoids potential linking.
Just to have said it: we launched this for a reason
The old approach of per-swap refund files didn't work in some very painful edge cases. The idea is that with option c) we can serve both needs - privacy for the privacy-focused and emergency rescue for those in need.
Please let us know what we can improve 🙏

Say adiós to per-swap refund files 👋
Say hola to the Boltz Rescue Key 🛟
At boltz.exchange, we’re dramatically simplifying swap UX: instead of downloading a new refund file for every submarine or chain swap, you’ll now only need one Boltz Rescue Key—downloaded once—and we'll never bother with downloads again 🙏
How It Works
🔑 The Boltz Rescue Key functions as master refund key, deriving a new key for every swap
🖥️ It works on any device and lets you create refunds for all swaps created with it.
⚛️All without compromising the non-custodial characteristic of Boltz Swaps.
Why It Matters
The Boltz Rescue Key reduces the risk of users misplacing individual refund files and losing access to funds locked in swaps—especially critical for web-based swaps (like boltz.exchange) that require external key backups.
