How it works

Install once. Every Aztec app on your machine gets native-speed proving automatically.

1

Install

Download the app. It lives in your menu bar and manages proving binaries by itself.

2

It stays out of the way

No windows, no interruptions. A tiny icon shows what's happening, live.

3

Apps get faster

Any app using the SDK finds Presto and proves natively instead of in the browser.

Why “presto”?

A zero-knowledge proof is a magic trick with math underneath: something is shown true without revealing why. And presto is both the reveal word and the musical marking for “very fast”.

Built for everyone who will never read the word WASM, and shouldn't have to.
