So you want to build an app

You want to build an application.

You start on Ethereum. You learn Solidity, deploy your smart contract, and build your front end. And then you realize that the gas fees are too high for you.

So you look for another option.

You decide to rely on an existing rollup, an L2. It works better, fees are much lower, and it’s faster. Then, one day, you need to make a small change to your application. You can’t do it. You’re forced to use the EVM; you always have to use the EVM. Also, you’re not a fan of paying rent to the sequencer of this Layer 2.

So, you look for another option and build your own rollup.

You go on Caldera or Conduit and decide to use a fully packaged Rollup as a Service solution. One day, you realize they can turn it off whenever they want, no reason given. You don’t like this. You wish your application were sovereign.

So you look for another option.

You decide to build your own appchain. Pretty soon, you understand why people don’t just do that. You find yourself forking Geth, the OP Stack… This is hard. You have no clue what’s going on. And then you see things about managing ZK proving and building fraud-proof systems, and you feel more overwhelmed than ever.

You just wanted to be free to build the application you want. Is that too much to ask for?

That’s where Hyli comes in.

You get to write your app in Rust, not have a single-use programming language forced on you. You prove it using the zkVM or DSL of your choice. You let a proving network generate the proofs on your behalf because what you care about is your app, or you decide to prove client-side or on your own server because that does matter to you. And you settle on Hyli.

You’re free. You’re sovereign. And yet, you aren’t isolated: thanks to proof composition, your app is fully composable with all the other apps on Hyli by design. They can interact smoothly without needing complex and unreliable bridges or opaque gas fees.

Hyli sets you free to build exactly the application you envisioned: streamlined, composable, fully sovereign, and without the blockchain headaches you never signed up for. Our testnet is going live in the weeks to come: sign up for our waitlist!
