No L2 developer cares about unilateral exits as much as Second.
1/ Bark 0.8.1 is out, and emergency exits no longer require your wallet online to broadcast. You can now fully presign your exit, including CPFPs, and share them with a third party to broadcast on your behalf.
ALT A hand-drawn break-glass emergency box with a hammer hanging beside it on a chain and three signed transactions linked by arrows inside, representing emergency exit transactions signed ahead of time and ready to broadcast later

when you use bark by @secondhq for sending/receiving bitcoin at low cost without channel management

5/ Lightning invoices can now set their own expiry, anywhere up to the server's limit (48 hours by default). Use `--expiry` in the CLI, `expiry_secs` over REST, or the new invoice builder in the SDK.

6/ Lots more, including paid Lightning sends that now finish even if Bark stops mid-settlement (fixed by @nitesh_btc), WASM wallets that ride out Esplora rate limits, and Bitcoin Core v32 support. Read the breaking changes before you upgrade: second.tech/docs/changelog

For the public signet demo Ark watchtower, I'm building a public status page that shows uptime, guarded VTXOs, expiry details, etc.
You'll be able to play around with the watchtower and watch it exit VTXOs for you non-custodially.

Bark Wallet runs on your node 🐶
Get paid over Ark instantly, or over Lightning with no channels to manage. On Umbrel and Start9.

The @secondhq team is excellent.
Bark lets users pay over Bitcoin, Ark, or Lightning and instantly see branding for their counterparty.
Verification without surveillance⚡️

i've paid a lot of lightning invoices and never once read one full, it's always the first and last 4 characters
they're about 300 long
Speed Wallet was the first solution i saw that showed the destination logo as a double check back in 2024
now Bark can show the shop's name under the invoice, if the shop registered with Branta
checking who you pay went from something nobody really reads to a simple name check

Bark by @secondhq delivers a simple, yet powerful way to take self-custodial bitcoin payments.
Available on @BtcpayServer, @start9labs, and @umbrel.
Branta is proud to work with Second to enhance the sending experience.

비트코인을 직접 보관하는 것만큼,
내 지갑에서 꺼내 쓰는 일도 쉬워야 한다고 생각합니다.
이번 @btckoreaconf 에서는 한국에서 바크(Bark)를 어떻게 활용할 수 있을지 살펴보는 발표가 있었습니다. 코코넛 월렛 데모 소식도 함께 소개됐습니다.
바크는 @secondhq가 만든 오픈소스 소프트웨어로, 지갑 앱에 Ark 송금과 라이트닝 결제 기능을 더할 수 있게 해줍니다.
한국에서는 이 가능성이 어떤 모습일지 들려주셔서 감사합니다 @matthewvuk2 🙏
바크와 코코넛 월렛이 함께하면 어떤 모습일까요? 👀🥥
Second 의 아크 bark의 한국 사용사례에 관해 @matthewvuk2 이 @btckoreaconf 에서 소개했습니다.
AI 비용 지불, Ark로 라이트닝/vtxo 전송, 곧 공개될 @Coconut_BTC 의 데모를 소개했습니다.
