Inco Lightning Launched on Base Sepolia, Enabling Developers To Build Confidential Apps

Confidentiality should be a fundamental tool for developers building onchain—just as it is in web2. Not something bolted on later, or reserved for niche use cases, but seamless, accessible, and deeply integrated into the developer experience.

With this in mind, we’re excited to announce that Inco Lightning, a fast, seamless solution developers can use to build confidential onchain applications, is now live on Base Sepolia testnet. 

Developers can get started building right away by visiting the docs. 

Users who want to try Inco Lightning can explore two applications on Base Sepolia: an onchain Hangman game, and Comfy, an interface for encrypting your onchain balance to keep it confidential.

Inco Lightning enables developers to build confidential applications directly on existing EVM chains. There’s no need to learn a new language, no new chain to deploy to, and no additional complexity introduced to the development stack. Just standard Solidity and a simple import.

Confidentiality unlocks a wide range of powerful onchain use cases—use cases that are either impossible or deeply compromised without it. From private payments and onchain games with hidden state to confidential voting and governance, the ability to compute on encrypted data allows developers to build new kinds of applications that respect user privacy while preserving decentralization.

With this release, we’re introducing private data types like euint, ebool, and eaddress, along with support for confidential compute functions e.add(), e.mul(), e.div() and encrypted randomness via e.randEuint8(). All of this is available through a single Solidity library: @inco/lightning/lib.sol.

You can get started in under 20 minutes: just write your confidential contracts in Solidity, connect your frontend via our JavaScript SDK, and deploy. That’s it. There’s no need for special infrastructure, no new tools or development environments, and no complex trusted setup assumptions.

Jump straight into the documentation at docs.inco.org to get started. We can’t wait to see what you create.

Stay up to date by following @inconetwork, and reach out if you’re building something with Inco Lightning—we’d love to hear about it.
