Hidden Crucible — Crucibulum Occultum

Medieval illuminated manuscript depicting a scholarly king

Open-source frontend SDK designed to bridge public application interfaces with Arcium's encrypted computation layer.

It provides client-side primitives for working with encrypted computation: encrypting inputs before submission, interacting with Arcium's execution environment, and verifying outcomes without exposing internal logic.

Quick Start

Install globally (recommended)

npm i -g arcium-frontend-sdk

Initialize project

crucible init my-app

This flow ensures that your data is encrypted locally before ever reaching the network, keeping your application's logic hidden within Arcium's confidential compute layer.
