Thanks for coming to Singapore. Next stop, Mumbai.
Hyperliquid.
Thank you to everyone who traveled near and far to make it to Monday's community event. Multiple members of the ecosystem hosted their own events to celebrate Hyperliquid and the community throughout the week. Thank you to every organizer for the hard work and dedication behind each one.
The builder booths were a highlight for many. To everyone building on Hyperliquid: thank you for bringing more of finance onchain and spreading the word.
Since last year, even more builders, users, and institutions have contributed to the ecosystem's growth. Hyperliquid's vision is to be infrastructure to house all finance, and every year, that vision becomes more of a reality.

@RobinhoodCrypto put real stocks onchain.
Launched on July 26, but with no prediction markets & no dispute layer.
So what we did differrent?
Docs: novakoracle.vercel.app/docs/…

Built on the layer:
• Range markets (LMSR AMM): buy a price range; prices = the crowd's forecast
• Yes/no + composite markets (AND / OR / BEFORE)
• Every fee split ⅓ resolvers · ⅓ jurors · ⅓ treasury
Plug it into any market: our SDK, a Solidity base contract, or Docker.

@RobinhoodCrypto put real stocks onchain. It launched with no prediction markets and no dispute layer.
So we built both from scratch.
Novak: the dispute oracle layer for tokenized stocks, and a paradigm AMM market on top of it.

How Novak settles a fact:
→ Resolvers read @chainlink + @RobinhoodCrypto stock tokens
→ 2-of-3 quorum proposes, evidence public
→ Anyone can dispute with a bond
→ Committees of ≤7, then ≤15, need 66%
→ No consensus? VOID, full refunds
Resolve it right, or refund it all

I’m at a very strange phase of my life and career
It feels like a high and low at the same time

I was recently building a coding agent and hit a problem that shows up fast: Long sessions make full-history context expensive and noisy. A common approach is to resend the entire chat history every turn. By turn 80, you're processing a lot of context just to recover the few details that actually matter. Oracle's Agent Memory takes a different approach:
→ Working: what the agent is doing now
→ Semantic: durable facts about the user/project
→ Episodic: what happened in past sessions
→ Procedural: rules for how the agent should behave
Old turns can be summarized, durable facts extracted, and only relevant memory pulled back into the prompt. Oracle's 80-turn benchmark: ~1.3K input tokens/request with memory versus ~13.9K with full history. Better answers on 48 turns vs 13 in the benchmark. The bigger takeaway for me: agent memory is a system-design problem, not simply a bigger-context problem. Full breakdown + code.

🤝 Paid partnership

Just wrapped another one. And Kolkata showed up.
Organized by @SuperteamIN, we brought Kolkata’s builders, developers, founders, and creators together for a @solana Mixer around the @colosseum Crypto World’s Fair Hackathon.
70+ registered. 30+ checked in. One room. A whole lot of ideas.
No stage. No long presentations. Just builders meeting builders, sharing ideas, finding collaborators, and talking about what they’re building.
@SuperteamIN × @eth_kolkata 🤝
A partnership that brought two communities together and made the evening even more special. Big shoutout to Eth_kolkata and everyone who helped make it happen.
And a massive shoutout to @SkyyCodes . To bring this this event's back again to Kolkata.
To everyone who showed up, connected, shared, and built with us: thank you.

Everyone’s talking about the $180B.
For Vayyl, the interesting number is one.
USDT0 brings a unified USDT supply to Stellar rather than another wrapped representation competing for liquidity.
That distinction goes deeper than liquidity for a shielded protocol.
Vayyl uses asset-specific pools: each pool settles a particular token, with its privacy set built around the users and liquidity in that pool.
So fragment the dollar across multiple representations, and you fragment:
Liquidity.
Anonymity.
Privacy.
One canonical USDT means:
One pool.
One shared liquidity base.
One larger crowd to disappear into.
As @jasonkarsh recently put it, better markets and stronger privacy depend on the rails Stellar is putting in place.
We’re building on those rails. – at Kolkata, India

We thought the liquidation circuit was done. It wasn't.
One assumption changed how we thought about private positions on Soroban
Sayan Roy | Devcon VIII 🇮🇳 retweeted
We understand what stellar is, therefore the target is the bottleneck privacy for the concurrent blocks of Orders . Settlements for the team with audits, clawback authority & most importantly unified payroll from the unified isolated pools itself.
We segregate the chunks by blocks(transaction nodes) slices(concurrent address)and codes(liquidity provider MMs)
The positions are set by authors from their own isolated private pools , the liquidity provider sets up the market strategies from the contract itself where the Oracle sets up the Moonlight rates, and then traders can set themselves up for a long or a short trade from the Orderbooks. Recognised by our very own Indexer.
Let's make this a success 💪🏻

Vayyl is through SCF pre-screening. Now, the decision is yours. Discover why we're building confidential settlement infrastructure for Stellar - and cast your vote.

spent the day with the superteam kolkata crew for proof of grass.
three years ago i was the one showing up to these rooms not knowing anyone. today i’m looking at a whole crew of that same energy and it hit different.
also we played football and i have the sore legs to prove it. 💜
