Non-custodial swap service Boltz officially halted all operations on August 3, 2026, due to a wave of automated AI-assisted attacks. The iteration speed of these cyberattacks proved to exceed the Boltz development team’s ability to respond to and patch their system’s vulnerabilities.
“Attackers are now iterating faster than a team of our size can find and patch them,” wrote a Boltz representative when announcing the shutdown of its services.
The collapse of the service began with a discovery on August 1. At that time, the Boltz team discovered a bug in the EVM integration and immediately restricted the swap feature for a series of major tokens: USDT, USDC, WBTC, TBTC, and RBTC. Two days later, they chose to suspend all operations. The halt of Boltz immediately triggered a domino effect on the Bull Bitcoin, Aqua, and ZEUS platforms, which had been relying on Boltz’s infrastructure. Although its service was completely paralyzed, Boltz ensured that customer funds were never at risk due to the use of a self-custodial architecture. The refund mechanism remains open for users.
Why Blockstream Moved Faster
The infrastructure void following Boltz’s shutdown forced other players to change their product launch schedules. Exactly one week after the incident, Blockstream officially released Blockstream Swaps to the beta testing stage on August 10, 2026.
This new exchange service facilitates BTC swaps on the mainnet, LBTC in the Liquid ecosystem, and Lightning without custodial intermediaries. Behind the scenes, the infrastructure runs using atomic swaps relying on HTLC (hashed time-locked contracts) contracts. Blockstream also implements Taproot and MuSig2 standards to maintain the efficiency of cooperative transactions within the network.
Currently, organizations can already request access to this beta program. Blockstream designed its service so that end users can pay Lightning invoices using their BTC or LBTC coins, without having to go through the hassle of opening a Lightning channel themselves.
Backup Solution Amid the Crisis
The entry of an entity as large as Blockstream right after the main provider collapsed sparked assumptions of a market takeover. However, the company dismissed this notion.
“We are not trying to replace any provider - this is a much-needed addition to increase redundancy,” Blockstream said regarding the intention behind its product launch.
The collapse of Boltz proves that the speed of AI attacks can now exceed the duration of manual fixes by development teams. In a landscape like this, users can no longer rely on a single gateway for the fate of their transactions.
