Turn your iPhone into part of a decentralized cloud, and receive ACU rewards for it. Acurast lets your phone run small compute jobs for developers. In return, you receive ACU rewards for the work your phone completes. No technical setup needed: if you have a spare iPhone or one sitting on a charger, you can take part. HOW IT WORKS 1. Install Acurast and create your account. 2. Pair your phone as a Processor. It takes about a minute. 3. Start Acurast. Your phone picks up compute jobs and collects rewards as it works. BEST SETUP A spare iPhone on a charger and Wi-Fi is ideal. Start Acurast, let the screen dim, and your phone contributes compute to the network. YOUR PHONE STAYS YOURS - Jobs run in a sandbox, separate from your photos, messages and other apps. - Acurast doesn't collect data linked to your identity. WHAT IS DEPIN? DePIN stands for decentralized physical infrastructure network: real devices owned by everyday people instead of one company's data center. Acurast is a DePIN for compute. Developers use Acurast to run apps and AI models on thousands of phones, without depending on a single cloud provider. Rewards depend on the jobs your phone completes and are not guaranteed. Join the Acurast Cloud Rebellion and make your phone part of the unstoppable cloud.

Shamir Safe: Protect Your Crypto with Secret Sharing Secure your cryptocurrency wallets using Shamir's Secret Sharing (SSS) — the same cryptographic standard used by banks and security professionals. Split your seed phrase, private keys, or any sensitive data into multiple encrypted shares. No single share reveals your secret. HOW IT WORKS: Shamir's Secret Sharing splits your secret into N shares, requiring only K shares to reconstruct it (K-of-N threshold). Example: • Split seed into 5 shares • Require 3 shares to recover • Distribute shares to trusted locations • Lose 2 shares? Still recover your secret! KEY FEATURES: Secret Sharing (SSS) • Split seed phrases, private keys, passwords • Custom threshold (K-of-N) • Supports BIP39 mnemonics • Any text up to 2000 characters Secure Storage • No internet required (offline-first) Share Management • Create unlimited shares • Label shares for organization Recovery Tools • Visual share counter • Threshold indicator • Step-by-step reconstruction • Validation before saving Privacy First • Zero data collection • No analytics, no tracking • Open-source cryptography • Works completely offline PERFECT FOR: • Crypto investors securing seed phrases • Multi-sig wallet backup strategies • Estate planning for digital assets • Teams sharing sensitive credentials • Anyone needing secure secret distribution USE CASES: 1. Personal Backup: - Create 3 shares, require 2 - Store: phone, laptop, safety deposit box - Lose one device? Still recover! 2. Family Inheritance: - Create 5 shares for family members - Require 3 of 5 to access - Ensures access if something happens 3. Team Security: - Split company wallet seed - Require 3 of 5 executives - Prevents single point of failure WHY SHAMIR SAFE? Better than paper backup: - No single point of failure - Distributed security - Threshold recovery Better than password manager: - Mathematical security - No master password to forget - Offline by design Better than hardware wallet alone: - Geographic distribution - Survives device loss - No vendor lock-in IMPORTANT SECURITY NOTES: 1. Never share all shares in one location 2. Test recovery BEFORE deleting original 3. Store shares in geographically separate places 4. Shamir Safe cannot recover lost shares 5. You are responsible for share security PRIVACY: Shamir Safe collects ZERO data: • No analytics • No tracking • No personal information • No internet connection required • Your secrets stay on your device
