Non-custodial swap platform Boltz suspended all its Bitcoin and cryptoasset swapping services indefinitely on August 3, 2026, after a months‑long barrage of automated, AI‑assisted probing and several contained exploits. The team said the attackers now adapt faster than its developers can identify and patch flaws, making it impossible to maintain reliable operations.
Boltz earlier disabled swaps for EVM‑based assets such as USDT, USDC, WBTC, TBTC and RBTC on August 1 due to a bug in its Ethereum Virtual Machine integration. Two days later, the company shut down all remaining swap functionality, including Bitcoin, Lightning and Liquid pairs. The public API remains online only to process cooperative refunds, and unilateral refunds still work without depending on Boltz infrastructure.
No user funds were lost. Because Boltz uses an atomic swap design where users retain control of their assets, the platform absorbed all operational losses itself. Its support team continues to assist those with unfinished transactions.
The suspension triggered service disruptions at several integrated wallets. Bull Bitcoin reported that Lightning payments and conversions between Liquid Bitcoin and on‑chain Bitcoin were temporarily disabled; the firm is evaluating replacement swap providers. ZEUS deactivated its own Boltz‑based deployment, and Aqua notified users of similar swap interruptions. No wallet reported customer asset losses.
Boltz attributed the attacks to “multiple resourceful groups” but did not provide technical indicators to independently confirm the role of artificial intelligence. The company has not published a detailed incident report, a remediation timeline, or conditions for restoring services, asking users not to expect an imminent reopening.
