Been working on this for a while! Happy to announce it properly.

[SevenLabs @SevenLabs_]

Introducing Carbon - a framework designed to simplify Solana data indexing using Rust 🦀

[Ferno @Ferno_ag]

Brace yourself French @solana community, as the fire house is coming.

The best Solana builder house, accelerator & incubator.
All year long Events, Workshops & Hackathons.

United, we stand with @collaterize & @JET_EUROPA_

Let there be fire once more. 🔥

Q2 2026. Paris.

[0xSol @Sam0xSol]

Just released Jetstreamer 0.5.0 which includes sequential mode: https://t.co/tmAsaLZkKv

This allows you to stream through solana old faithful txns sequentially at around 100-150k TPS with a good internet connection and clock speed!

Uses ripget's fast download windowing 🔥🔥🔥

[Solana @solana]

BREAKING: Solana flipped Ethereum in total RWA holders for the first time, according to @RWA_xyz 🤯

[Beff (e/acc) @beffjezos]

Just prompt it.

Excessively complicated agentic workflow engineering is going to be eaten up by better models anyway

[mert @mert]

you guys are way too emotional

the chains now scale, regulation is clear, and AI has reduced cost of shipping

crypto is internet native capitalism

for it to die, both the internet and capitalism would need to die and that's not happening

we'll be back higher than ever

[Jarry Xiao @jarxiao]

Solana allows you to move money around with:
• >40000x lower fees (0.000005 SOL * $116/SOL at today's prices vs. $25 for a wire)
• >200000x less time (0.4 seconds vs. 1-3 business days)
• infinitely more transparency (block explorer + public ledger vs. radio silence)

[Kellian @KellianDev]

Introducing Accelerate events between Breakpoint was such a good decision by @SolanaConf 🔥

[Solana @solana]

Solana returns to America 🇺🇸

Join us in Miami on May 5th, 2026 for Accelerate USA

[Banshee @banshee7l]

If your team is looking for Solana/Rust engineers, feel free to reach out.
We have some capacity in February at @SevenLabs_.

[Kellian @KellianDev]

@ParvatRajSingh Yes it does, you don’t need to rewrite the code that integrates these data sources. But of course you rely on infra providers subscriptions to get the data into your pipeline.

[Kellian @KellianDev]

Indexing on Solana is a solved problem at this point.

> Jetstreamer for historical data
> Yellowstone gRPC for realtime data (or now LaserStream so you don't have to worry about disconnects)
> Carbon to decode and pipe the data to your logic

We've come very far 🥹

[Helius @Helius]

NEW

You can now automatically replay historical data with LaserStream for the last 24 hours (previously was 3,000 slots or ~20 minutes)

The longer replay window and 60 blocks/s catch up speed means more time to recover, faster repairs, and better data integrity

Enjoy

[0xSol @Sam0xSol]

Working on a new open source + free dataset of all solana account updates as an add-on to jetstreamer, stay tuned

[Kellian @KellianDev]

@blueshift just ships

we dont talk about @multisig enough

- best multisig on solana
- best neobank infra on solana
- best mobile wallet on solana
- best design on solana

the future of finance is built on solana and it's built on squads.

“Bots” are bullish.

“Bots” are 70-80% of traditional finance.

It’s called algorithmic trading.

[Kellian @KellianDev]

Thanks @Sam0xSol for the great work on Jetstreamer.

[SevenLabs @SevenLabs_]

Carbon now supports Jetstreamer as a data source for historical transaction data.

In this video, we parse all Token 2022 instructions from slots 367,200,000 to 367,201,000 with a few lines of code ✨

Check out the example repo ⬇️

[Kellian @KellianDev]

Excited for this year’s @SolanaConf in Abu Dhabi!

I’ll be giving a quick talk on the Developer Stage about Carbon as we release v1.0.

Would love to connect if you’re around.

[Banshee @banshee7l]

We've reached 500 stars on Carbon 🤩

One year of building, shipping and improving the framework with all the @SevenLabs_ team.
Appreciate everyone using it - we’re pushing even harder now.

Would love for this to be the beginning of a streak of good decisions. Europe has been falling behind so quickly and it’s pretty sad to see.

[@levelsio @levelsio]

🇪🇺 Something is finally happening!

EU is:
- scaling down the GDPR (data privacy laws)
- watering down the AI Act (more like AI Ban), and
- finally removing the Cookie Banner laws

This gets us a bit closer to the top eu/acc ideas being reached
