Blockstream Wallet integrates Boltz to enable trustless exchange between Lightning and Liquid

Blockstream announces that its mobile wallet has completed a major upgrade, allowing users to trustlessly swap between the Lightning Network and Liquid Network via Boltz. This update enables users to pay Lightning invoices directly with Liquid Bitcoin (LBTC) without manually managing channels or maintaining inbound liquidity, further enhancing the seamlessness and convenience of cross-layer Bitcoin network usage.

According to Blockstream, this integration relies on Hash Time-Locked Contracts (HTLC) to ensure all swaps are executed atomically: either all succeed or all revert. If a transaction fails, funds are automatically returned to the original wallet, all without third-party custody, increasing user funds’ security. Boltz acts as a non-custodial swap service provider, handling exchanges between Lightning and Liquid efficiently and trustlessly.

This update is especially significant for everyday Bitcoin users. The Liquid network offers fast settlement and stronger privacy, while the Lightning network is suitable for instant small payments. The upgrade tightly integrates both networks, allowing users to complete Lightning payments with LBTC without needing to understand complex channel management, providing a smoother cross-layer payment experience.

Blockstream also disclosed additional planned features, including on-chain swaps that enable users to freely move funds between the main Bitcoin chain (BTC mainnet), Liquid, and Lightning through a single interface. Furthermore, Blockstream plans to support hardware wallets (such as Blockstream Jade) to directly receive Lightning payments, further improving interoperability among ecosystem tools.

With the official integration of Boltz swaps, Blockstream’s wallet is becoming a central gateway connecting multiple layers of the Bitcoin network, offering a more comprehensive solution for users seeking privacy, high speed, and flexible payment options. This upgrade also promotes the adoption and real-world application of the Bitcoin Layer 2 ecosystem.
