What you need to know before using Eclipse

We are not your typical rollup.

We're not really an "Ethereum" rollup, or a "Solana" rollup, or anything else like that. The point of Eclipse is that it can be deployed to any chain. Right now, we support deploying to Celestia (Cosmos), Polygon, and EigenLayer, but many more chains are on the roadmap.

You get to pick what virtual machine you write code for.

And we support all existing tooling.

One of the virtual machine options we offer is the Solana (Sealevel) virtual machine. This means that any tooling you can use with Solana, you can also use with Eclipse. (In technical terms, we implement the Solana JSON-RPC.) This ranges from things as simple as the Solana CLI and the Solflare wallet to as sophisticated as Seahorse, which lets you write Solana programs in Python rather than Rust. In this case, you'd need to install the Solana Tool Suite in order to use Eclipse.

You can also deploy Ethereum virtual machine (EVM) chains with Eclipse. So tooling like Truffle, Metamask, and Remix all work out-of-the-box.

It’s not done yet, but we want you to get your feet wet.

The vision for Eclipse is ambitious. We’re rebuilding many existing Layer 1 blockchains for the future.

In the long run, developers can spin up their own customizable blockchain-as-a-service, but it won’t be a full-fledged blockchain like Ethereum or Solana. It will be a trust-minimized “rollup”: a chain that isn’t secure by itself, but borrows security from some other blockchain.

But we’re not quite there yet. Right now, all Eclipse chains are deployed by the Eclipse team directly. We have capped the number of partners that we are supporting with our testnets, because we provide substantial Solutions Engineering resources for each partner. We're focusing on use cases that require high customization needs. If you think this is you, you should reach out to us at

Mainnet Eclipse chains are anticipated to launch in Summer 2023. Until then, keep posted for announcements about general purpose public testnets. We are excited to hear what you think.
