[Arbitrum @arbitrum]

Founder House kicks off this weekend in London. 🇬🇧

Our mentors and speakers are ready to help shape the next generation of products in the programmable economy.

From July 10-12, our mentors and speakers will be supporting founders as they refine their products, strengthen their go-to-market strategy and compete for $300K in prizes & grants.

Dive deeper into how the L1 (@ethereum) component is factored into the gas used on @arbitrum.

[José FP @josefp_crypto]

Gentle introduction into how gas works on @arbitrum L2/L3 chains.

0:00 gas on @ethereum
2:57 gas on arbitrum rollups
7:00 gas on arbitrum anytrust

[José FP @josefp_crypto]

Key takeaways (contd):

- This extra cost depends on the gas prices of Ethereum, so gas spikes on Ethereum require more gas for your transaction on Arbitrum.

- Always estimate the gas limit with `estimateGas` (or similar). Hardcoding the gas limit is not a good idea!

Oh whats this, the first Timeboosted txn on @arbitrum sepolia? 👀 hm

[Offchain @Offchain]

Say hello to true interop for @ethereum.

In collaboration with many teams, we're building a universal intents engine.

The goal?

Seamlessly connect @arbitrum chains and other Ethereum L2s with < 3s crosschain swaps and transfers to achieve flawless UX. 🧵

BoLD is live on Arbitrum Sepolia testnet! Permissionless validation on Arbitrum chains is closer than ever 🚀

[Arbitrum Developers @ArbitrumDevs]

Arbitrum’s BOLDEST upgrade just hit Arbitrum Sepolia!

Permissionless validation coming soon. Decentralization up and to the right!

[Derek @leeederek]

I don't think people realize how much experimentation & innovation we're cooking up at @offchain

In 2024, we've:
- Literally added a 2nd VM to @arbitrum technology
- Proposed new txn ordering policies to capture L2 MEV while keeping block times at 250ms (faster than Solana!)
- Collaborated deeply with @EspressoSys on a myriad of efforts, including decentralized sequencing
- Completed some hardcore stress testing of the next-gen fraud proof dispute protocol (BoLD)
- Become the leading AppChain tech stack in the industry
- Continued to be the home for DeFi

2025 is going to be insane, and I didn't even talk about the amazing work that @prylabs has been up to with Dencun and now the upcoming Pectra fork.

@0x_allan @offchain Welcome to the team! 🥳

[José FP @josefp_crypto]

We just updated all the tutorial scripts for new devs looking to experiment with @arbitrum:

Open to hearing if anything should be added or updated!

[Arbitrum @arbitrum]

It’s been three years of building together on Arbitrum.

Today, we bring you Stylus! Designed to drive innovation and foster collaboration across blockchains.

Stylus is now on mainnet. Open new doors. Shape what's ahead.

Do More. With Stylus.

[Offchain @Offchain]

Today, we're excited to share a roadmap of Arbitrum innovations that align closely with one of our core values.

Your Chain, Your Rules.

This includes horizontal scaling, decentralized sequencing, ZK proofs, Stylus (MultiVM support), and more. 👇

@DZack23 We'll miss you, sir. Wish you all the best 🙏

[Arbitrum @arbitrum]

Fraud Proofs took us to a Stage 1 rollup.

Today, with BOLD, we’re on our way to becoming a Stage 2 rollup!💙

BOLD, permissionless validation on Arbitrum, is now live on testnet! 🧵

[Ed Felten @EdFelten]

Ten years ago today, I drew a diagram on my office whiteboard at @princeton. It showed what is today called an “interactive fraud proof”. This was the seed from which Arbitrum grew. 🧵

[Arbitrum @arbitrum]

It’s been an amazing year for the Arbitrum ecosystem and community!

As part of the Foundation's commitment to transparency and giving the community a better understanding of operations, today we're sharing the annual transparency report.
