Kite

Kite is a developer tool for Solidity which lets you to never expose your private key to env variables.

If the privatekey is exposed in some file then it can get stolen by a shady NPM package, leak through a Chrome extension/Vs code extension or even get sniffed by your AI companion “innocently” watching your .env file

Traditionally, developers need to expose their private key by adding it to their IDE before deploying a project. This makes the key highly vulnerable to attacks and theft through malware, browser extensions, or other exploits. Many past hacks have occurred because of this exact issue.

Kite removes this risk by providing a secure interface. Developers simply run a shell command on Foundry, which generates a link. Opening this link presents all the necessary fields to deploy and verify a smart contract without ever exposing the private key.

Additionally, Kite supports EIP-5792, enabling developers to run all transactions with a single click. It converts test scripts into browser-executable scripts, allowing hot wallets to run them seamlessly. This also helps teams where the authorized person responsible for contract deployment may not have deep technical knowledge and doesn't want to share their privatekey with developers. With Kite, they can simply open the link, review the details, and sign the transaction with a hot wallet.

Our mission is to create a safer environment for developers to build the future of Web3 removing unnecessary risks and making deployment faster, simpler, and more secure.

Kite is built on top of Foundry. We use SSH scripts to securely fetch all the required data for deployment and script execution. The frontend is built with Next.js, providing a smooth and responsive interface for developers.

For blockchain interactions, we leverage the Wagmi library, which allows us to send calls and implement EIP-5792 for one-click execution. This integration ensures that test scripts can be converted into browser-executable scripts, making it possible to run them directly from hot wallets with minimal friction.

By combining these technologies, Kite delivers a developer-friendly and secure workflow that bridges local development tools with seamless, browser-based deployment.
