In just two weeks: some of the largest supply-chain attacks in history, a major commercial LLM sabotaging legitimate ML research requests, and a US export ban kneecapping the world's access to a major model release. More than ever, we need Open, Verifiable Inference. Today we start shipping direct responses. A🧵:

Introducing Hashi: a new era of Bitcoin finance on Sui. Bitcoin's market cap exceeds $1 trillion. < 0.5% of it is used in DeFi. Hashi is here to change that, with commitments from industry leaders including BitGo, Bullish, Erebor Bank, FalconX, Fordefi, Ledger, and more.

Private money and natively issued USDT secured on the biggest blockchain. @utexocom is finally bringing true utility to Bitcoin.

Our mission at Kash is to completely redefine how the world prices and distributes beliefs. We are meeting YOU where you already are, starting with social media. To accelerate this journey, we are proud to have partnered with top-tier VCs and raised $2M to bring prediction markets to your feed. Backed by @TheSpartanGroup and @BigBrainVC, with participation from Coinbase Ventures, Polaris Fund, Moonrock Capital, Halo Capital, Kosmos Ventures and Fabric Ventures. [Kash Flash Market: Will at least 3 verified accounts with over 100k followers quote post this announcement within the first 12 hours?]

Thanks for the shoutout @MikeZajko! We've been one of the most active funds since 2022, especially in the depths of the bear market while many were pulling back. I firmly believe the best teams and projects exist in any market env. and cycles are irrelevant in early stage venture. We're always on the lookout for generational teams, bull or bear.

Congrats to the team at @zardotapp on the new round!

Legend is the world’s first Trader vs. Trader arena. Trading is already the world's biggest video game - it’s time to make it multiplayer. Today, we’re proud to share that we've raised $1.5M in pre seed funding, from top-tier institutions and angels to build the best competitive-social layer for trading. Become Legend.

Live trading will become a spectator sport, an inevitable conclusion of hyperfinancialization and mirroring the same trajectory of videogaming and the multi-billion dollar esports industry. The outcomes of live trading are exponentially more competitive, high-stakes, fast-paced and accessible. @legendtrade is an inevitability of this trend and generation.

@DriftProtocol @JupiterExchange @HyperliquidX @pacifica_fi @bulktrade 12/ Aggregators won bridges (Wormhole) and spot (Jupiter). Perps are next. Trade the router, not the venue. That’s Ranger.

@DriftProtocol @JupiterExchange @HyperliquidX @pacifica_fi @bulktrade 11/ Venue leadership will keep rotating; fragmentation will likely deepen. The sane response isn’t more tabs—it’s better routing. One interface, one book, fills that clear.

1/ The war on liquidity is happening in the perps DEX market. Fragmented books and fragmented incentives demand a unifier. That unifier is @ranger_finance.
