    This has been a long time in the making; it feels so great to finally be able to announce this. Native Bitcoin trading is an imperative. Permissionless global liquidity for the largest asset in crypto.

    We've been quiet because we're heads down on the most important scaling work we've ever done for Spark. This shit is hard. It's why it's never been done. Scaling a parallel DAG with sub-second finality under extreme concurrency is insane. Everyone's grinding, even partners flew

    We recently shipped our SDK to early partners building trading frontends. I wired up a full swap UI in <10min with Cursor. Bought and sold a token from a live partner pool. Zero friction, native Bitcoin. Flashnet + Spark = Bitcoin-native markets, end to end.

    Hi all, just wanted to let everyone know that today is my last day at @MEonBTC. I am honored to have helped launch and build atop the ordinals and runes marketplaces, and was truly a roller coaster ride with all of you in the BTC community. I apologize that I was ultimately

    We’re seeing a spike in Spark SSP failures, causing some outbound sat transfers to fail. All funds are safe. Flashnet’s internal health switch automatically pauses outbounds when issues arise, protecting users and preventing cascades. Overall swap success remains above 99.5%,

    Bitcoin just got a new stablecoin. It’s called USDB, and it just went live on Spark. Welcome, @brale_xyz

    Unilateral exit is now live. > You can leave Spark anytime > No matter what happens If you have to ask anyone besides Bitcoin for your Bitcoin back, it’s wrapped.

    Thanks for riding with us through Flashnet's first real-world testing. Refunds were processed, and everyone is whole. We’ve found issues and will be back soon to run it again smoothly. For those who got swaps through, hope you caught a glimpse of what’s ahead. Back soon!

    Brale + Flashnet + Spark = the cheapest place to buy BTC in the next 6 months.

    🚨Demo🚨 You can’t trade Bitcoin on a DEX. @flashnet fixes that. @ethanmarcus demos how. Built on @spark (🫡 @lightspark), powered by USDB (a Brale-issued stablecoin), Flashnet unlocks native BTC ↔ USDB swaps on-chain, low-fee, and fast.
