<h2 id="blockstream-steps-in-with-swaps-beta">Blockstream Steps In With Swaps Beta</h2>
<a href="https://x.com/Blockstream" rel="noopener noreferrer nofollow">@Blockstream</a> has launched a public beta of Blockstream Swaps, a service offering atomic swaps across Bitcoin, the Liquid sidechain and the Lightning Network. <cite>The product lets users pay Lightning invoices directly from their Liquid bitcoin (LBTC) balances in a self-custodial way, removing the need to manage payment channels or maintain inbound liquidity.</cite>
<cite>Atomic swaps use smart contract technology to allow two parties to exchange assets directly, without a third-party intermediary. The swap is atomic, meaning it either completes in full for both parties or does not happen at all, eliminating counterparty risk.</cite><cite>The mechanism uses hash time-locked contracts (HTLCs) to ensure that swaps either complete or automatically return funds to the sender's wallet.</cite>
The timing is notable. The launch comes just days after <a href="https://x.com/Boltzhq" rel="noopener noreferrer nofollow">@Boltzhq</a>, one of the primary non-custodial swap providers for the Bitcoin ecosystem, pulled its services offline.

<cite>Boltz suspended all Bitcoin mainchain, Lightning and Liquid swap services indefinitely on August 3, 2026, citing months of AI-assisted attacks that outpaced its patching capacity.</cite><cite>The company wrote that it had seen a steady rise in automated, AI-assisted probing of its infrastructure and had dealt with several exploits, adding: "Each was contained, but the pattern is clear: attackers now iterate faster than a team our size can find and patch."</cite>
<cite>Boltz said no user funds were at risk because its swaps are non-custodial.</cite><cite>Its HTLC-based design protected user assets throughout, with the company absorbing operational losses on its own books, and the refund API remaining live.</cite><cite>The shutdown affected downstream wallets and services including ZEUS, Aqua and Bull Bitcoin, all of which relied on Boltz infrastructure for swap functionality.</cite>
The incident highlights a broader security challenge facing smaller open-source teams in crypto. <cite>Blockchain security firm Blockaid reported that crypto projects lost more than $1 billion to hacks during the first half of 2026, with the number of verified exploit incidents already surpassing the total recorded in all of 2025.</cite><cite>TRM Labs found that infrastructure and operational compromises accounted for roughly 76% of crypto hack losses in the first half of 2026.</cite>
Boltz has given no timeline for restoring its service. <cite>The company said swaps are disabled "until further notice" and that it cannot provide an estimate for when the service will return.</cite>
