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.

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!

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 👇🏻

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 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.

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

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 👇🏻

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.

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.
