If you’re a founder who missed the ultimate in-person mentorship experience, here’s a look at what went down at Arbitrum Founder House London 🇬🇧

We've brought teams together under one roof for a 3-day founder residency where they:

• Refined their product & GTM strategies
• Had mentorship sessions with our ecosystem partners
• Competed for $300k in prizes

Catch the highlights. 👇🏻

If you’re spending time solving:

• Wallet onboarding
• Gas management
• Cross-chain UX
• Transaction approvals

This is worth a read.

Read how @zerodev_app’s account infrastructure stack can help simplify these challenges for applications built on the Arbitrum Platform. 👇🏻

We're aware of a report of a bridge hack on Arbitrum and are investigating. We can confirm that the transaction in question originated from a third party protocol, and the Arbitrum native bridge has not been hacked or exploited in any way.

We will coordinate with the third party team and will report more details when we have them.

Always great to see more teams investing in developer tooling and sharing engineering insights publicly.

Looking forward to following the updates and seeing what builders create with Bitget Wallet X. 🤝🏻

[Bitget Wallet Devs @BitgetWalletX]

Hello fellow developers/builders

If you're building wallets, DeFi protocols, payment products, or autonomous agents, we'd love to connect.

This is our official account of the Bitget Wallet eng team, and will be the official source of all developer updates, tech insights, and ecosystem integrations.

We'll be sharing:
- Engineering best practices and tech insights
- Updates for API, SDK and dev tools
- Success cases/Root cause analysis for integrations
- Thoughts on onchain infrastructure

We believe in helping developers connect onchain with better tools:

Introducing: Bitget Wallet X
Crypto is now multichain and AI-driven. Developers need simple and better ways to access onchain liquidity, market data, and infrastructure.

Bitget Wallet X is Bitget Wallet's infrastructure stack for developers and enterprises.

Through our Swap API and Market API, we provide wallets, DeFi protocols, aggregators, payment applications, solvers, and AI agents with a single point of access to essential onchain capabilities.

Battle-tested and proven at scale: Our proprietary tech and integrated systems processed $56 billion in culminative trading volume, with daily volume peaking at $39 million, and a transaction success rate of 99.5%.

Bitget Wallet X supports major ecosystems including Ethereum, Solana, BNB Chain, Base, Arbitrum, HyperCore, HyperEVM, Polygon, Avalanche, Morph, and Robinhood Chain.

Successful partner integrations include @0xProject, @deBridge, @lifiprotocol, @CoWSwap, @VeloraDEX, and @symbiosis_fi. Our partners are already accessing better quotes, routing, and liquidity through Bitget Wallet X.

We'll also share our work and thinking across security, multichain architecture, protocol integrations, and onchain infrastructure.

We want to connect with more developers and partners, learning mutually as we explore a more open and efficient onchain infrastructure for the industry.

Builders and Devs, let's connect!

[Arbitrum Developers @ArbitrumDevs]

Robinhood Chain lets developers build with the same EVM tools and workflows they already know:

- Solidity contracts
- Foundry deploys
- Viem reads
- Wagmi writes
- ERC-20 approvals

Here's how to build your first Robinhood Chain app by @hummusonrails 👇🏻

[Arbitrum Developers @ArbitrumDevs]

Most apps and users are not expected to be affected, but teams that consume or verify eth_getProof proofs may need to update their tooling.

The design is not final. Any change would proceed through the standard governance process, including an ArbOS upgrade and a Constitutional DAO vote.

[Arbitrum Developers @ArbitrumDevs]

Builders and infrastructure teams: we want your feedback on a research-stage proposal that could change how Arbitrum represents and proves state.

Read the RFC and join the discussion:

[Arbitrum Developers @ArbitrumDevs]

Arbitrum scales Ethereum without compromising its security or decentralization, and this research advances that mission.

A more efficient state layer could reduce disk load and lower the hardware floor for running nodes, while keeping state authenticated and proofs verifiable.

[Ben Greenberg @hummusonrails]

I keep seeing embedded wallets framed as a login shortcut. That undersells what app teams can ship.

On @Arbitrum, a smart account can turn wallet setup into product policy: who gets sponsored execution, and under what rule. 🔐

[9lives 💙 @9livesso]

9lives is now deployed natively on @Arbitrum One, built with Stylus. 🐱

This is the first step in a bigger transition. 9lives is moving to where the liquidity is, starting with Arbitrum and heading to the @RobinhoodApp Chain.

Early deployment, so expect a few rough edges while our RPC infra catches up.

[Arbitrum Developers @ArbitrumDevs]

If you're still building or holding funds on Arbitrum Nova, now's the time to act.

We are currently halfway through the 90-day migration window, during which time developers and users are encouraged to migrate from Arbitrum Nova to Arbitrum One.

Learn more. 👇

[Arbitrum Developers @ArbitrumDevs]

Important Update on Arbitrum Nova.

As per a recent proposal, the ArbitrumDAO has voted to minimize Arbitrum Nova by transitioning it into a maintenance-oriented state with reduced capacity and deprioritized support.

A thread on what this means for developers and users 👇🏻

[Arbitrum Developers @ArbitrumDevs]

Exciting to see @cobuildersxyz go live with their Hardhat 3 plugin suite.

Developers can now compile, test and deploy Rust and Solidity smart contracts together in the Hardhat plugin suite with one single command.

Learn more below. 👇

[CoBuilders @cobuildersxyz]

Until now, building on @arbitrum Stylus meant having to leave your Hardhat workflow behind.

Not anymore.

We shipped a Hardhat 3 plugin suite that brings the full Stylus lifecycle into Hardhat. Rust contracts right next to Solidity.

Builder’s Block #021 is live!

This edition features Robinhood Chain by @RobinhoodCrypto going live on the Arbitrum Platform, @zerodev_app's new wallet, & Founder House London concluding with $300K awarded to winning teams.
