What’s happening at Walnut.

If you've ever looked at a Starknet transaction and wondered where all the gas goes — we’ve got the answer.

Starknet is an ecosystem that made a bold decision: it launched with its own custom language—Cairo. That means, among other things, it had to build everything from scratch. Cairo devs couldn’t rely on any of the existing blockchain tooling available for Solidity, Ethereum, or other blockchain ecosystems.

Walnut Labs is partnering with Offchain Labs—the team behind Arbitrum—to improve the debugging experience across the Arbitrum stack. This effort is part of our broader mission to bring modern debugging and monitoring tools to emerging rollup ecosystems.
