Blockstream Green app brings liquid lightning swap capability to streamline private bitcoin payments

Blockstream has introduced a major update to its Green mobile wallet that enables a seamless Liquid Lightning swap for faster, self-custodial bitcoin payments across layers.

The new version of the Blockstream Green app adds atomic swap functionality between the Lightning and Liquid networks, letting users pay Lightning invoices directly from their Liquid bitcoin (LBTC) balances. As a result, they no longer need to manage channels or maintain inbound liquidity, which has often been a technical barrier for everyday users.

Lightning specializes in instant, low-fee bitcoin transactions. Liquid, by contrast, is a federated sidechain that emphasizes confidential transactions and easier handling of unspent transaction outputs (UTXOs).

By connecting these layers through atomic swaps lightning liquid functionality, Blockstream aims to offer the speed of Lightning and the privacy of Liquid in a single, user-friendly experience.

How the new swap mechanism works

The swap process is fully self-custodial and uses cryptographic hash locks to coordinate transactions across both networks.

Moreover, the design ensures that either both sides of the swap complete successfully or neither does, removing counterparty risk and aligning with self custodial bitcoin payments best practices.

If a swap fails for any reason, the funds automatically return to the original wallet. That said, users do not need to trust an intermediary, since the protocol enforces this all-or-nothing behavior at the cryptographic level.

This approach is meant to give non-technical users access to advanced multi-layer bitcoin tools without exposing them to complex operational hazards.

For many users, the ability to pay lightning invoice payments directly from LBTC balances means they can spend in real-world environments that support Lightning while keeping their long-term holdings on a more private layer.

Cafes, online stores, and service platforms that already accept Lightning can be paid instantly, while users continue to enjoy the liquid bitcoin privacy layer for their savings.

Benefits for merchants and power users

The integration also targets merchants that want fast payments but robust treasury management. Merchants can accept incoming funds over Lightning and then secure those assets in a Liquid wallet, avoiding the need to run large hot wallets or reveal balances publicly. However, they can still maintain the low fees and quick settlement times that Lightning offers.

According to Blockstream, this multi-layer workflow is designed to fit existing commerce setups with minimal friction. Moreover, it could appeal to power users and institutions that require better UTXO management and privacy while maintaining access to high-speed payment rails.

The company notes that the liquid lightning swap capability is live now in the Green app for supported platforms. Users only need to update the application to start routing transactions between Lightning and Liquid, without deep configuration changes or new infrastructure.

Upcoming improvements: on-chain swaps and hardware support

Blockstream has outlined a roadmap of upcoming enhancements that will expand interoperability further. A key step will be on chain swap support, which will allow users to move funds between bitcoin’s main chain, Liquid, and Lightning from within a single interface.

With this next phase, the Green wallet could operate as a central hub for navigating bitcoin’s layered ecosystem. Moreover, users would be able to rebalance funds on-chain, in Liquid, or over Lightning without leaving the app, improving liquidity management across all three environments.

Another planned feature is hardware wallet lightning support. Blockstream intends to let users receive Lightning payments to devices like the Blockstream Jade, integrating higher security for frequent payers and merchants.

That said, this will extend the trust-minimized design by enabling Lightning activity with keys stored on dedicated hardware.

Interoperability and user control

These developments fit into Blockstream’s broader push for interoperable second-layer protocols that preserve user control over private keys. By combining on-chain, Liquid, and Lightning capabilities in a coherent workflow, the company is trying to reduce friction while keeping custody in the user’s hands.

Over time, improved tools and integrations may encourage more people to experiment with multi-layer bitcoin usage. However, the core design principle remains that users retain direct control of their funds, with cryptographic safeguards instead of centralized custodians.

In summary, the latest update to Green connects Lightning speed with Liquid privacy, sets the stage for broader swap functionality, and strengthens bitcoin’s layered infrastructure for both everyday users and advanced operators.
