At **Hyperweb**, we’re building the future of blockchain development—one where developers can launch, test, and connect across multiple chains with ease. And today, that vision takes a major step forward:

**Starship now supports Ethereum.**

This isn’t just another checkbox feature. It’s a game-changer for anyone building cross-chain applications, testing smart contracts across ecosystems, or prototyping multichain infrastructure.

## Why Ethereum Matters

Ethereum is still the gravity center of Web3. From DeFi to NFTs, it’s the most battle-tested smart contract platform, with the richest ecosystem of tools and developers.

Until now, spinning up an Ethereum devnet alongside other chains like Cosmos required separate tools, complex orchestration, and manual setups. That friction slowed down testing and made true _interchain_ development harder than it needed to be.

With Ethereum in Starship, we change that.

## A Unified Environment for Blockchain Development

Starship already lets you spin up Cosmos chains, relayers, explorers, and registries—all from a simple YAML config. Now, you can drop Ethereum into the mix just as easily.

Imagine testing your smart contract on Ethereum, then watching it interact with Cosmos-based apps—all in the same local environment. No juggling separate toolchains. No context switching. Just one command and you’re live.

This means:

- **End-to-end interchain testing** is finally accessible.
- **Cross-ecosystem dApps** can be developed in one place.
- **Experimentation between Ethereum and Cosmos** becomes frictionless.

## Unlocking Real Interoperability

Interoperability isn’t just about bridging tokens. It’s about developers being able to _build_ across chains with confidence and speed. When tools get out of the way, ideas ship faster—and that’s the spirit of Starship.

With Ethereum now a first-class citizen in the Starship universe, we’re giving builders a launchpad to test, simulate, and connect ecosystems that were previously siloed.

## What’s Next?

This is just the beginning. The Hyperweb vision is full-stack, full-chain, and fully open. Ethereum support in Starship is a foundational step—unlocking new patterns for testing, devnet coordination, and eventually… production-grade multichain systems.

Whether you’re working on an Ethereum app that talks to Cosmos, or a Cosmos chain that wants to tap into Ethereum liquidity, Starship makes that future easier to build today.
