About Aster

Aster is a next-generation hardware wallet that puts you in full control of your digital assets. Designed with a focus on security, transparency, and user experience, Aster enables true self-custody without relying on third-party services or cloud-based infrastructure.

Our wallet uses a tamper-resistant secure element (SE) to store your private keys, ensuring they are protected even if the device is physically compromised. The firmware is open-source and auditable, meaning you can verify every line of code yourself or through a trusted third party.

Aster is built for both individual users and institutional clients. Whether you're holding Bitcoin, Ethereum, or dozens of altcoins, Aster supports over 500+ cryptocurrencies and tokens with more being added regularly through firmware updates.

We believe in transparency and open development. Our roadmap, audits, and technical documentation are publicly available, and we encourage community involvement in the development process.

• Non-custodial — you own your keys
• Open-source firmware with reproducible builds
• Support for 500+ cryptocurrencies
• Multi-signature support for advanced users
• Shamir Secret Sharing for backup redundancy
• Secure element chip for key isolation
• Full audit logs and compliance-ready documentation

Features

Security

Security is at the heart of Aster. We employ a proprietary secure element for private key storage, a secure boot process, and encrypted firmware updates to prevent unauthorized access. Our device is fully air-gapped to eliminate network-based attacks, and every production batch undergoes third-party audits.

Aster follows a rigorous threat-modeling approach and continuously updates its cryptographic primitives. We integrate physical tamper detection, supply chain verification, and offer optional Shamir Secret Sharing for key backups. All aspects of our hardware and firmware are publicly documented for community scrutiny.

Each Aster device is manufactured under strict security protocols, with supply chain tracking to prevent tampering during production. Firmware updates are signed and verified cryptographically to ensure authenticity.

• Secure Element (SE) chip for key isolation
• Encrypted PIN protection
• Secure boot and firmware verification
• Physical tamper detection and response
• Supply chain verification
• Reproducible builds for transparency
• Regular third-party security audits

Whitepaper

Aster Whitepaper

Version 1.0 — 2025-04-05

Executive Summary
Aster is a next-generation cold hardware wallet designed to provide the highest level of security and transparency for cryptocurrency storage. Our solution combines secure hardware, open-source firmware, and a privacy-centric philosophy. We focus on true self-custody of digital assets by removing any single points of failure and empowering users with auditable code and verifiable processes.

Introduction
The proliferation of digital assets requires robust, user-friendly, and verifiable cold storage solutions. Aster addresses key industry pain points: ease of use, secure key generation and storage, verifiable code, and multi-currency support. In this whitepaper we explain our architecture, security model, compliance goals and roadmap to full production release.

Technical Overview
• Secure Element: Proprietary tamper-resistant chip for private key storage.
• Air-Gapped Transactions: Signing operations occur fully offline.
• Open Firmware: Fully auditable and reproducible builds.
• Backup & Recovery: BIP39 mnemonic plus optional Shamir Secret Sharing for redundancy.
• Cross-Platform: Compatible with major operating systems and wallet software.
• Modular Design: New cryptocurrencies and features can be added via firmware updates.

Security Architecture
Aster follows a strict threat-modeling approach. We outline the cryptographic primitives, secure boot process, and secure communication channels to ensure that private keys never leave the device. We maintain transparent documentation of threat models and third-party audits. We include physical tamper resistance, encrypted firmware, and secure supply chain measures.

User Experience
Aster integrates a simple, intuitive interface that guides users through setup, backup, and transaction signing. Our UI/UX principles prioritize safety without sacrificing convenience.

Compliance and Certification
Aster provides documentation to facilitate regulatory compliance and advertising certification (including Google Ads crypto wallet certification). We are committed to full transparency with regulators and partners.

Roadmap
Phase 1: Finalize hardware and firmware audits.
Phase 2: Beta testing with early adopters.
Phase 3: Public release and integration with major wallets.
Phase 4: Enterprise features including multi-signature management and custom policy enforcement.
Phase 5: Ongoing research and development for future security standards.
