Hey @zakehowell

There is nothing out of the ordinary in these transactions. It's simply a transfer from the company's on-chain wallet to the company's Kraken account.

I've added the references below for you to review.

Company Polygon hot Wallet: https://t.co/epYM6OiZvV

The transfer to Kraken: https://t.co/ft416hU7GW

Kraken wallet: https://t.co/GBcK2ABJb6

The token has not yet launched, so no tokens have been distributed yet.

It’s officially here. @ZenithFdn is an EVM environment built on @CantonNetwork which allows Canton applications to compose atomically with EVM applications.

Testnet is now live.

Let’s show tradfi what defi can do 🔥🔥🔥

[Zenith @ZenithFdn]

Over the next few months, the Zenith team will travel across four continents, and we're hosting at two of those stops.

@kbwofficial in Seoul and @token2049 in Singapore are where we're investing the most energy this autumn, bringing together TradFi and DeFi partners in the kind of setting where real conversations happen.

Here's what we have planned:

Seoul: Korean Blockchain Week
September 29, 17:30-21:30
Invite-only dinner, co-hosted with @redstone_defi and @Figure. An intimate seated evening built for the conversations that don't fit a conference agenda. If you are working at the intersection of institutional finance and digital assets and want to be in the room, reach out directly. Details: https://t.co/ZnZHGIwHIr

September 30
@HeslinKim speaks at the RealFi x Asia Stablecoin Conference in Seoul. Check info: https://t.co/0H1mThBtXc

October 1, 11:00-14:00
The Seoul Table, an institutional lunch at Conrad Seoul, co-hosted with @KaikoData, @utila_io, and Happyblock. Meet the teams behind institutional digital asset adoption alongside banks, funds, and capital market participants working through the same questions. RSVP: https://t.co/Noz24tXJrl

Singapore: TOKEN2049 Week
October 7, 9:00-12:00
Opening Bell, an institutional breakfast co-hosted with @trex_network and @KaikoData. 10 minutes from Marina Bay Sands and timed to kick off your TOKEN2049 day. Relaxed setting, high-quality conversations, and the right people in the room. Quality breakfast on us, RSVP: https://t.co/OWY6l9G3En

While in Singapore, @HeslinKim is on stage four times across the week, catch him at:
- TokenizeThis 2026 by @redstone_defi on October 6: https://t.co/8ibCvCJYaA
- @blockworksDAS Digital Asset Summit on October 7: https://t.co/I2nbsTE3Ev
- Agentic Finance by @moreandmorebd on October 8: https://t.co/4rPNjinXIZ
- HSC Asset Management by @mpost_io Singapore on October 8: https://t.co/vuG0jaHcm0
- @rwasummitglobal on October 9 as part of RWA Week: https://t.co/B1QuY5efS1

Beyond Seoul and Singapore, autumn also takes us to New York for the Canton Summit on September 15, Germany the same week for @conf3rence with @NorbertVadas, and Rome in November for @AIBC_World with Heslin.

If you're going to be at any of these, we'd like to meet you, reach out ahead or find us on the ground.

Zth.

JUST IN: Zenith has been invited to join Progmat's Tokenized JGB and On-chain Repo Working Group, a consortium bringing together MUFG, Mizuho, Sumitomo Mitsui, BlackRock Japan, State Street, SBI Securities, Japan Exchange Group, and other major players, conducting a joint study on bringing Japan's $1.6 trillion JGB (Japanese Government Bond) repo market on-chain.

Japan's JGB repo market is one of the largest in the world, processing ¥250-270 trillion annually and representing roughly 10% of the global government bond-backed repo market. Today it settles a business day after a trade is executed, operates within traditional market hours, and requires manual processes at every step. The working group is targeting same-day settlement, 24/7 availability, and cross-border access, enabling fully on-chain repo transactions using tokenized JGB collateral paired with stablecoin cash legs via lending protocols.

A comprehensive report is expected in October 2026, with issuance pilots targeted for later this year. Read the full announcement: https://t.co/3qkmqesLfN

[Zenith @ZenithFdn]

Zenith is expanding and we're hiring two people to grow with us.

> Business Development Associate: shape Zenith's launch by managing inbound client relationships, qualifying partnerships, and building the workflows that keep everything moving. You're organized, relationship-driven, and fluent in both Web3 and institutional finance conversations.
https://t.co/xEg65zmUXO

> Head of Security (Engineering): own security end-to-end across our full stack. This is a deeply technical role: threat modeling, vulnerability research, incident response, secure architecture from blockchain protocol layer to cloud infrastructure.
https://t.co/tnMf9WkkzC

If you want to work at the forefront of where DeFi meets institutional finance with an ambitious team playing the long game, we'd love to hear from you.

Canton builders in Cannes ☕️

Joined the @CantonFdn x @ZenithFdn Builders Breakfast at EthCC this morning - great conversations about where institutional DeFi is heading.

Find us if you're here 😉

[Henri Kämäräinen @Henrixbor]

Time to clear our Social calendars. @CantonNetwork, @zenithfdn, it's time to cook.

[Zenith @ZenithFdn]

They told us it was impossible. We did it anyways. Today we announce Zenith.

POV: You wake up H2 2026 and Ethereum‘s application layer has fully teleported into Wall Street’s blockchain of choice. We are that protocol, now opening a direct on-ramp between the world’s largest programmable and institutional blockchain ecosystems.

[Ethproofs @eth_proofs]

breakthrough by @thezkcloud :)

→ Fetching Ethereum block data to feed into zkVMs used to take minutes.
→ ZkCloud slashed that by 1,000x — from hundreds of seconds to hundreds of milliseconds.
→ The trick? A custom fetcher using Reth's debug_executionWitness. Open source soon™.

Time spent outside proving for block 22,795,300:

🥇 ZkCloud: 3s 😎
🥈 Succinct: 117s
🥉 Cysic: 298s
4️⃣ Brevis: 311s
5️⃣ Snarkify: 317s
6️⃣ ZKM: 365s

[Henri Kämäräinen @Henrixbor]

In Cannes for EthCC? Come say hi! 😃

[Henri Kämäräinen @Henrixbor]

ZK could be the next major meta-play that has yet to gain widespread attention. I can’t help but wonder about the opportunity cost many might face by not delving deeper into ZK now if we simply let things unfold.

[Henri Kämäräinen @Henrixbor]

@thezkcloud It does feel like the start of a new era is on the horizon☁️

[Henri Kämäräinen @Henrixbor]

@teemupai @jur7v2 @HeslinKim @jur7v3 Feel free to reach out to me on discord on tg to discuss more :)

[Henri Kämäräinen @Henrixbor]

Bitcoin hits 100k, and the Firestarter launch happens on the same day. Coincidence? I don't think so.

[Julia Suontama @SuontamaJulia]

Funny thing I've noticed since diving into Web3 this summer: coming from the outside, I'm constantly amazed at how sharp people are. The way they think is next-level. No one takes anything at face value—they question, explore different angles, and come up with the most out-of-the-box solutions.

Makes me wonder where this mindset comes from.

Eager to meet these folks again this week when heading to #DevCon2024

See you at zk events and rAAVE!
Few #zeroknowledge events to join:
https://t.co/6jkGDUL52c
https://t.co/Cc5sRqOWOL

[zerokn0wledge.hl 🪬✨ @zerokn0wledge_]

For the first time ever, @aztecnetwork blocks were ZK proved by third parties in its ProverNet contest, aiming to test provers ability to produce the proofs necessary validate Aztec blocks.

15 teams stepped up to the challenge and produced Aztec blocks over several days, competing in two categories (custom and generic)

Now, the results are in. ⤵️

Custom:

➊ @gevulot_network

Generic*:

➊ @gevulot_network (avg time: 419s)
➋ @MarlinProtocol (avg time: 430s)
➌ @lagrangedev (avg time: 483s)
➍ @Ember_Stake (avg time: 604s)

* ) four teams tied, proving all eligible blocks in time

Great to see @aztecnetwork pushing towards prover decentralization and how strong these teams have performed!

[Norbert Vadas @NorbertVadas]

Come and meet @gevulot_network in Singapore next week.

[Norbert Vadas @NorbertVadas]

Coming to Montreal for @__zkhack__ ?
Check out the bounties of @gevulot_network !

Bounty #1: Port a ZK-rollup prover to Gevulot
Hint: @zksync 's prover or @StarkWareLtd 's Stwo might be great candidates.

[Teemu π @vectordrift]

Tfw you’re used to crypto asset liquidity, but then you go try to buy stocks in a local stock exchange and discover that multibillion dollar companies have less than 100K€ order book depth. Also seemingly no market making.

Wtf is tradfi doing?
