[ambient.xyz @ambient_xyz]

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🧵:

[Sui @SuiNetwork]

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.

[Big Brain Holdings @BigBrainVC]

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

[Utexo @utexocom]

Utexo has raised $7.5M from @tether, @BigBrainVC, and @PortalVentures to bring USDT natively on Bitcoin.

After more than a decade, USDT is finally coming home.

[kash @kash_bot]

Our mission at Kash is to completely redefine how the world prices and distributes beliefs.

[Sam @ReliableNarr]

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.

[Big Brain Holdings @BigBrainVC]

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

[Legend @legendtrade]

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.

[Sam @ReliableNarr]

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.

[Big Brain Holdings @BigBrainVC]

@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.

[Big Brain Holdings @BigBrainVC]

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.

[Big Brain Holdings @BigBrainVC]

@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.
