Blockstream has launched Blockstream Swaps in beta testing after noncustodial swap provider Boltz suspended its services following months of automated probing and several exploits. According to Blockstream's August 10 announcement, the in-house service is already being tested with select participants, with development now being accelerated after Boltz stopped processing swaps on August 3. The Bitcoin infrastructure company stated that the product was under development before the shutdown and is intended to add another option for users moving funds between Bitcoin, Lightning and Liquid networks. The timing proves crucial as Boltz has offered only a 'soon as possible' restore timeline, with its web app still showing Swap Services Disabled.
Boltz attributed its suspension to a steady increase in automated, AI-assisted attempts to probe its infrastructure, along with several exploits that the team said were contained. As reported by Blockstream, the company kept its swap services offline because attackers were iterating faster than its developers could identify and patch weaknesses. Boltz emphasized that customer funds were never at risk because its architecture is self-custodial, with refund mechanisms remaining available while normal swap operations were disabled. The company had initially restricted swaps involving assets such as USDT, USDC, WBTC, TBTC and RBTC after identifying a bug in its Ethereum Virtual Machine integration on August 1, before suspending all services two days later.
According to Blockstream, the new service is designed as an in-house swaps feature built for the Lightning and Liquid networks, with organizations now able to request access to the beta program. The company stated that development was 'well into' its testing process before the Boltz suspension, and the recent disruption reinforced its decision to speed up the rollout. Blockstream emphasized that 'We are not seeking to replace any providers' and sees Blockstream Swaps as 'a much-needed addition to improve redundancy and resilience to the ecosystem.' The service supports users holding BTC on Bitcoin mainnet or LBTC on Liquid who need to interact with Lightning without managing Lightning channels directly.
The Boltz disruption has created a significant liquidity gap in the Bitcoin ecosystem, with Liquid handling 1,163,119 transactions in Q1 2026, nearly five times the same quarter a year earlier. This surge in activity highlights the critical role of self-custodial bridges in the Bitcoin Layer 2 ecosystem, as users and services lose one of the faster routes for moving value through the ecosystem. Blockstream's timing becomes crucial as it can capture repeat transfers as the path of least resistance, inheriting some of the flow that Boltz used to handle. The company does not need to create demand across the main chain, Liquid and Lightning - it only needs to become a usable path inside the flows that already exist, potentially monetizing the bottleneck through increased activity around swap points.
The competitive landscape presents both opportunities and risks for Blockstream's new service. While Boltz remains offline with incoming operators working to fix vulnerabilities, restoration is still described as 'soon as possible'. Blockstream faces a narrow window to win early usage and maintain its advantage, as the company must prove it can stay reliable under similar attack pressure that forced Boltz to shut down. The bear case remains Boltz's potential return with better security and similar speed, which could give Blockstream a testing bump rather than lasting market share. The wider risk loop extends beyond one provider, as Bitcoin L2s are now live networks with real activity, meaning higher flow means higher reward for attackers, making the durable edge go to the path that stays online.
