Since launching on mainnet, we've been hard at work refining Bark's DX and UX, guided by all the feedback we've been getting from early integrators and users. Some of the highlights from releases 0.2.3 to 0.3.0: Bark now pays LNURL links anywhere it accepts a Lightning address, you can run barkd as a containerized web app to back browser-based wallets, and wallet setup is simpler with one consistent flow and per-platform storage defaults. Your bitcoin also stays liquid mid-exit: an Ark balance can be spent right up until your emergency exit's leaf transaction is confirmed on-chain (spending quietly cancels the ongoing exit).

Bark is now a Lightning backend option in Alby Hub—enabling self-custodial Lightning payments for all your connected wallets with no Lightning node, channels, or liquidity to manage. The integration enables Bark across all NWC-enabled apps like Alby Go, Zeus, and Damus, and even agents like Claude and GPT. More details:

Bark went live with wallet apps ready to go on day one, built by bitcoiners who'd been working alongside us since long before launch. Noah, from the team behind Blixt, is the Ark wallet you'd expect from self-custodial wallet veterans, including some fancy Ark-infused Lightning addresses for static, free, offline payments. iOS and Android. Arké, from Christoph Ono, leverages years of the Bitcoin Design Community's open-source UX work, and pioneers brand-new UX for Ark. iOS only. Both apps are open source and available today.

SECOND IS NOW ON MAINNET. Bark, our implementation of the Ark protocol, is available for anyone to start making bitcoin payments. Included in the launch are our mainnet Ark server, the Bark SDK, and multiple wallets to try from day one.

Recent Bark releases 0.1.4, 0.2.0, and 0.2.1 have been packed with updates. The highlights: Slim VTXO storage cuts wallet memory use 20–100x, real-time notifications replace polling so wallets update the instant something happens, and a single payment request now bundles Ark, Lightning, and on-chain into one QR. And to ensure Bark slots nicely into existing stacks, emergency exits and boarding can now both be driven by an external on-chain wallet with its own signer. Full changelog: second.tech/docs/changelog
