Introducing Hark Handoff
It is verifiably the best model ever built for using the internet.
It can order food, book flights, shop, deeply research, you name it - better and more affordably than frontier models.
Would you let an AI agent run your company's treasury?
Not if it holds the keys. Not if every balance is public.
A prototype from the Mysten team gives agents the job but not the keys and keeps the numbers encrypted.
Built on Seal MPC and confidential transfers on Sui.
🧵
We are going to see a lot of vertically focused AI native companies accelerate.
Routers, open-source models and specialized post-training enabled by companies like @FireworksAI_HQ have all made dramatic advances and the combination of the three is driving accelerating growth.
Companies like @wearelegora can now use their data to post-train an open-source model and then combine it with frontier models behind a router to get the same or better outcomes at lower costs than the frontier alone.
This dramatically improves the business model for all these companies. @cognition seeing similar trends.
Kimi K3 is live on Fireworks. Day 0, inference and training. US-hosted, and zero data retention.
This is the first frontier open model in the 3 trillion parameter class. It sports 1M context, native vision, and reasoning that rivals the top closed models.
Boom.
We have spent years thinking about what it would actually take to move capital markets fully onchain
and we honestly believe JUST tokenizing assets solves only the easiest part of the problem
bringing capital markets onchain is not simply about putting assets on a blockchain
it’s about allowing independent institutions to coordinate on shared infrastructure WITHOUT EXPOSING every position, balance or transaction to everyone
while also not cutting themselves off from the broader onchain economy
this is what #Sui Spheres are designed to make possible
inside a sphere, institutions can create controlled environments for private markets, lending, collateral and other multi-party workflows
they can decide who participates, what each participant can see and which rules govern the system
but unlike an isolated private network, a sui sphere can connect outward when public settlement, liquidity, assets or auditability are needed
and sui spheres do not have to exist in isolation from one another
different spheres can selectively connect when assets or workflows need to move between them, while each sphere keeps its own rules around participation and visibility
and also without forcing every participant and every piece of activity into one fully open system
this is the architecture capital markets actually need to go fully onchain
NOT one public blockchain for everything
and NOT thousands of private systems that cannot talk to one another
but a network of controlled environments, each built for a specific market or workflow, that can connect whenever value needs to move
control where control matters
openness where openness creates value
Do you know why the stablecoin market cap on
@SuiNetwork is higher than DeFi TVL?
> Sui Stablecoin Market Cap: ~$441.4M
> Sui Total Value Locked: ~$419.1M
Stablecoin MC is the total value of every stablecoin currently circulating on the Sui chain:
> $USDC ≈ $275M
> Sui Dollar / $USDSUI ≈ $72M
> $FDUSD ≈ $43M
> $BUCK≈ $26M
This metric counts all of them, no matter where they sit
DeFi TVL sums up the assets locked inside protocols like @navi_protocol, @suilendprotocol, or DEX pools chasing yield
Old ecosystems train users to park capital in vaults because moving money around is slow, expensive, and clunky
Sui flips that dynamic and is proving money movement is what accrues network value for enterprises and agents
> Zero fees on stablecoin payments
> Lightning fast transfers
> Bandwidth in the millions of TPS
When moving money is basically frictionless, capital doesn’t need to sit locked for minor yield
It stays liquid in wallets, payment apps, commerce flows, and autonomous AI agents
The liquid cash gap is wider than it looks. Sui isn’t behaving like a static yield vault
It’s starting to look like a high-speed transactional economy. $$ Flow matters more than locked liquidity
BREAKING:
SEC Chair Paul Atkins just laid out the fallback plan.
"I'm optimistic that Congress will pass the CLARITY Act."
But listen to what comes next.
The SEC is "ready, willing and able to come out with rules."
Either to implement the bill.
Or if Congress fails to act.
The top securities regulator in America.
Just said crypto rules are coming either way.
"We need the certainty of a statute that will help future-proof so that we have clear direction to go forward."
That's the preference. A law, not agency discretion.
But the message underneath it.
Washington isn't debating whether crypto gets regulated.
It's debating whether Congress or the SEC writes the rules.
Congress passing the CLARITY Act is the clean path.
The SEC acting alone is the backup.
Either way, the era of regulatory ambiguity is ending.
The vote is in.
A team of experienced cryptographers both inside Mysten and reputable Unis reached unanimous agreement on both the post-quantum signature schemes and the derivation path standards.
TL;DR
• Native authenticator → lattice-based (with planned hardware wallet/HSM ecosystem support)
• Smart contract Quantum Vault → hash-based
Both are NIST-compliant, serving different security and deployment goals. Spoiler that the native auth will be free of gas, zero penalties and cost for users obsessed with security. We prefer better key hygiene than charging for better security, that’s Sui’s non-negotiable ethics from day 1, even multi-sig and zkLogin was always for free.

I’m personally preparing a comprehensive report covering the final selections, the technical rationale behind each decision, and a detailed analysis, with facts and proofs, of why several alternative proposals were rejected.
Sui Quantum @ 2026
UPDATE: A new CLARITY Act draft has been released, merging the Senate Banking and Agriculture Committee versions and adding an ethics provision for the first time.
A motion to proceed is expected Monday or Tuesday, with a possible floor vote the week of August 3.
I have been building in this space through several cycles
when markets turn down, you see very quickly which teams were selling a vision and which teams were actually building toward one
so far in 2026, we have delivered gasless stablecoin transfers, sui dollar and deepbook margin on mainnet
we have put confidential transfers into public beta, launched deepbook predict and hashi on testnet
and pushed programmable transactions beyond 6 million TPS in a public experiment
and we are nowhere near done
before the year is over, deepBook predict and confidential transfers will be live on mainnet
and sui will support quantum-secure addresses and programmable quantum vaults
plus, there is much more coming around payments, security and AI this year that we cannot share yet
all I can tell you right now is that we are not slowing down
if anything, we are moving faster
