Bitcoin bridge Boltz has indefinitely suspended its swap services after a surge in AI-assisted attacks. The company stated attackers were iterating faster than its small team could deploy patches. While no user funds were lost due to Boltz's non-custodial design, the shutdown has disrupted services like Aqua Wallet and Bull Bitcoin, highlighting growing security risks for open-source crypto projects.
Boltz service suspension
- ▪The service allows users to move Bitcoin between the main blockchain, the Lightning Network, and the Liquid Network
- ▪Boltz, a non-custodial Bitcoin bridge, has indefinitely suspended its swap services as of August 3, 2026
- ▪Boltz confirmed no user funds were at risk due to its non-custodial design, and any financial losses were absorbed by the company
- ▪According to DeFiLlama, Boltz had a total value locked of approximately $262,000 at the time of the shutdown
AI-assisted hacking attacks
- ▪A similar trend involves the Coldcard hardware wallet, where an AI-linked exploit led to the theft of over $100 million in Bitcoin
- ▪The suspension was a response to a steady rise in automated, AI-assisted attacks from "multiple resourceful groups."
- ▪The pace of attacks against Boltz saw a "drastic acceleration" in the days immediately before the service was suspended
- ▪The company clarified the shutdown was not due to a single incident but a pattern of several contained exploits over recent months
Impact on Bitcoin ecosystem
- ▪Bull Bitcoin warned its users that Lightning payments and Liquid-to-Bitcoin swaps would "fail without explanation."
- ▪The suspension disrupted services for wallets that rely on Boltz, including Bull Bitcoin, Aqua Wallet, and ZEUS
Security challenges for small teams
- ▪Boltz described the situation as a "major paradigm shift for Bitcoin services operating on an open source stack."
- ▪Swan co-founder Yan Pritzker said the overhead for security against AI attackers may "price out many innovative startups."
- ▪Lucas Ferreira of Vinteum noted that Boltz is a small but "brilliant team" facing sophisticated, AI-powered hacking groups
- ▪Boltz stated that attackers now "iterate faster than a team our size can find and patch" vulnerabilities
- ▪Solana Foundation's CISO Michael Coates said the industry must switch to automated defenses as humans cannot scale to meet AI-powered threats
