Abstract
This proposal seeks a grant of 80,000 ALGO to fund the official review, integration, and release of Algorand support within the AirGap ecosystem via its modular architecture known as Isolated Modules.
A community developer has already built a working Algorand module. With this grant, AirGap’s core development team will conduct a full code review, ensure security compliance, and integrate the module into AirGap Vault and Wallet — enabling secure offline storage, transaction signing, and broadcasting for Algorand users.
Once complete, the Algorand community will gain access to AirGap’s open-source, security-first cold wallet solution, designed to work even in regions where hardware wallets are not accessible. Users will be able to create and manage Algorand accounts securely on air-gapped devices, with no need for internet access or proprietary hardware.

Present Proposal
AirGap is a self-custody open-source cold wallet that transforms any spare smartphone into an airgapped cold wallet, providing maximum security without the need for dedicated hardware wallets. It consists of two applications:
-
AirGap Vault (offline) – Stores private keys completely offline and signs transactions securely via QR codes, preventing any exposure to online threats.
-
AirGap Wallet (online) – Manages balances, initiates transactions, and interacts with dApps, ensuring a seamless user experience.
To enhance blockchain coverage and user flexibility, AirGap introduced Isolated Modules, which allow developers to independently build and sideload new blockchain integrations.
A community developer has built an Algorand module using this system. The next step is to audit, improve (if needed), and officially integrate this module into the AirGap ecosystem — enabling seamless Algorand support in both AirGap Vault and Wallet apps.
To ensure proper review, security validation, and user-ready integration, we are requesting a grant of 80,000 ALGO to fund developer time, QA processes, and release management.
But why us?
True Randomness for Seed Generation – Unlike traditional wallets that rely on a device’s RNG (which can be manipulated), AirGap supports dice roll and coin flip entropy to generate seed phrases, ensuring verifiable, human-generated randomness for maximum security.
Totally Airgapped Security – AirGap Vault operates without Bluetooth, USB cables, Wi-Fi, or NFC, making it 100% offline, eliminating any potential attack vector from connected devices.
Advanced Security features - AirGap includes BIP-39 passphrase protection, BIP-85 deterministic seed derivation, and social recovery, allowing users to add extra layers of security and flexibility to their wallets.
Deliverables
1. Code Review and Audit (3 weeks after grant approval)
• Security and architecture review by core AirGap developers.
• Identification of improvements or compliance issues.
• Direct collaboration with the original developer to patch concerns.
2. Integration into AirGap Apps (2 weeks after code review)
• Finalize module packaging to match AirGap’s standards.
• Add support hooks for Algorand in Vault (offline signing) and Wallet (network interaction).
• UX adjustments for Algorand-specific workflows.
3. Production Release (1 week after Integration into AirGap apps)
• Release new versions of AirGap Vault and Wallet with built-in Algorand support.
• Update documentation and changelogs.
4. Post integration Maintenance Period (Upto 2 years post-launch)
• Bugfixes and minor version updates will be offered for upto 2 years.
• Community support will be handled via AirGap Discord and GitHub issues.
Official Algorand Module Integration:
1. Algorand support available in both AirGap Vault and AirGap Wallet apps (iOS & Android): Code pushed to the public AirGap GitHub repository under a clearly labeled versioned release.
2. Educational Content:
-
How Algorand was integrated.
-
Benefits of using AirGap for Algorand users.
-
Step-by-step guide for creating an Algorand account via AirGap.
-
Video showcasing the user flow.
3. Verification Process:
• Public GitHub issue tracker will be used for milestone tracking.
• Weekly status updates on the progress.
Benefits to community
Integrating Algorand into AirGap will offer Algorand users access to a robust, open-source cold wallet solution with no need for specialized hardware.
Key Benefits:
-
Secure Cold Storage Without Hardware Wallets: AirGap separates private key handling (Vault) from internet-connected devices (Wallet), offering a true air-gapped experience. This means Algorand users can store their assets offline without purchasing additional hardware.
-
Open-Source and Accessible to All: AirGap is fully open-source and freely available. This ensures transparency, verifiability, and community-driven improvement — making it a trustworthy option for privacy-conscious users and developers alike.
-
Broader Global Reach: Many Algorand users in underserved regions may not have access to mainstream hardware wallets. With AirGap, all they need is a spare smartphone to create an isolated cold wallet setup — democratizing access to secure self-custody.
-
Strong Security Foundation: AirGap has a proven track record of security-first architecture, including Encrypted QR-code-based transaction broadcasting, Isolation of private key operations, and Secure, offline storage of keys in Vault.
The integration of Algorand via Isolated Modules showcases the modular power of AirGap, paving the way for future community-driven blockchain integrations without compromising app integrity or user security.
By funding this proposal, the Algorand ecosystem will benefit from a secure, offline-first wallet experience that empowers users worldwide — especially those who prioritize privacy, sovereignty, and accessibility.
