ZetaChain Announces Mainnet on Arbitrum! ARB's Ecosystem Continues to Expand

ZetaChain has officially announced full mainnet support for Arbitrum, marking a significant leap in the evolution of seamless cross-chain development and usage.

This integration enables over 50 million active wallets within the Arbitrum ecosystem to natively access and interact with other major blockchains such as Bitcoin, Ethereum, and Solana—all through ZetaChain's Universal EVM (Ethereum Virtual Machine).

Revolutionizing Cross-Chain Experiences

With Arbitrum now fully supported on the ZetaChain mainnet, users no longer need to switch networks or rely on external bridges.

Instead, they can manage their assets—including viewing balances, staking, providing liquidity, and trading Arbitrum-native tokens like ARB—directly through ZetaHub, the platform’s access portal.

This simplifies the user experience while boosting interoperability and accessibility across blockchains.

ZetaHub currently boasts over 500,000 monthly active users, with a peak daily transaction volume of 184,000, according to DappRadar. The inclusion of Arbitrum is expected to significantly enhance both the platform's liquidity and its growing user base.

Empowering Developers with Universal Smart Contracts

The most transformative aspect of this integration lies in its support for Universal Apps — decentralized applications built once on ZetaChain that can interact natively with multiple blockchains.

Developers no longer need to create custom cross-chain bridges or adjust dApp logic for each blockchain. Instead, they can build once and launch everywhere, dramatically reducing development time and complexity.

With Arbitrum support enabled, developers can:

1. Build dApps that natively support ARB and other Arbitrum-based tokens.

2. Interact directly with smart contracts across Bitcoin, Ethereum, Solana, and Arbitrum.

3. Eliminate the need for token wrapping, network switching, or multi-step transactions.

This streamlined development experience helps future-proof applications, as any updates or improvements in the Arbitrum ecosystem will be immediately accessible without requiring separate integration efforts.

Why Arbitrum?

As a leading Ethereum Layer 2 solution, Arbitrum is widely recognized for its high throughput, low transaction fees, and scalability. By integrating Arbitrum, ZetaChain delivers on its promise to combine performance with cross-chain usability, empowering developers and users alike to leverage the best of both worlds.

ZetaChain’s Universal EVM makes it possible to deploy dApps that seamlessly span the entire blockchain ecosystem, connecting assets, contracts, and users across chains in a unified, intuitive experience.

This positions ZetaChain as a cornerstone for the future of multi-chain applications and decentralized finance (DeFi).

What This Means for Users

With the Arbitrum integration, users can:

1. Use BTC, ETH, USDC, and other tokens on Arbitrum-based dApps directly from any connected chain.

2. Swap, send, or interact with assets across blockchains without wrapping tokens or switching networks.

3. Enjoy an intuitive and fast user experience, powered by Arbitrum's speed and ZetaChain’s infrastructure.

4. ZetaHub now acts as a cross-chain command center, allowing users to monitor their holdings, provide liquidity, and manage assets across the expanding ZetaChain ecosystem — all from one platform.

Building a Universal Blockchain

ZetaChain's vision is bold: to build a Universal Blockchain that delivers native, seamless access to every major chain in the crypto space.

The integration of Arbitrum is a major milestone toward this goal, and the platform has stated plans to support even more mainstream public chains shortly.

With ZetaChain, the lines between blockchains are beginning to blur. Developers gain access to the tools they need to create truly interoperable dApps, while users benefit from a unified and frictionless crypto experience.

Conclusion

The addition of Arbitrum to ZetaChain’s mainnet is more than just a technical upgrade—it’s a redefinition of how decentralized applications and users engage across the blockchain ecosystem.

From single-contract cross-chain apps to seamless wallet interactions, ZetaChain continues to pave the way toward a fully connected, Universal Blockchain future.
