Proposal Brief
We are seeking $75,000 to bring native TRON support to AirGap, while building the ecosystem’s first agentic payment infrastructure for a true cold wallet. AirGap is one of the few wallets that keeps signing keys permanently offline, and our approach extends this security model to AI agents without compromising user custody.
This will be the first agentic payment implementation for a true cold wallet, establishing secure infrastructure for AI-driven commerce, recurring payments, and autonomous financial agents. As AI rapidly becomes a core part of the Web3 experience, this project lays the foundation for secure, permissioned automation on TRON without sacrificing the security principles that cold wallets are built on.

Project Overview
AirGap is a self-custody open-source cold wallet that transforms any spare smartphone into an air-gapped 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.
Project Goal
Integrate native TRON support into AirGap Wallet and Vault while introducing secure agentic payments through TRON’s native permission system. This enables users to safely delegate on-chain actions to AI agents without ever exposing or moving their private keys online.
Unique Value Proposition:
We are building first truly secure AI agent architecture for TRON wallets — AI agents can execute transactions without users surrendering custody of their private keys.
Built on TRON’s native permission model it will uses Active Permissions instead of custom smart contracts, making delegation transparent, auditable, and protocol-native.
Why AirGap is best positioned to build this agentic payment infrastructure?
1. Hardware Wallet Accessibility
Problem:Devices like Ledger or Trezor are hard to source in many regions, and prone to supply chain risks.
AirGap’s Solution:Converts any spare smartphone into a secure cold wallet — no proprietary hardware or shipment required .
2. Online Wallet Vulnerabiliti es
Problem:Hot wallets (extensions, mobile apps) expose private keys to malware and phishing on connected devic es.
AirGap’s Solution:Uses a two-device model — Vault (offline) securely holds keys; Wallet (online) manages transactions. Keys never touch the inter net.
3. Weak Entropy & PRNG At tacks
Problem:Most wallets rely on system-generated entropy that may be predic table.
AirGap’s Solution:Adds real-world randomness through camera, mic, gyroscope, touch — plus dice roll and coin flip options — to protect against PRNG vulnerabi lities.
4. Closed-Source Hardware Lim itations
Problem:Many hardware wallets are closed-source, limiting auditability a nd trust.
AirGap’s Solution:Fully open-source and reproducible — users can audit the code and build fr om source.
5. Poor Key Management Flexibility
Problem:Limited support for advanced key derivation and bac kup options.
AirGap’s Solution:Supports BIP-39 Passphrase, BIP-85 see d derivations
6. Lack of Multi-Accou nt Arrangement
Problem:Most wallets are not optimized for users managing multiple accounts across chains.
AirGap’s Solution:Allows users to create and manage multiple accounts with ease, offering structured organization and control in one s ecure interface.
Additional Security Features
-
Totally Air-gapped Security – AirGap Vault operates without Bluetooth, USB cables, Wi-Fi, or NFC, making it 100% offline, eliminating any potential attack vector from connected devices.
-
Fully open source & free to use: Anyone can audit, contribute to, or fork AirGap - ensuring transparency, trust, and no vendor lock-in.
-
Globally accessible: No shipping, customs, or availability issues anyone with a spare smartphone, anywhere in the world, can set up a secure cold wallet instantly.
-
True Randomness for Seed Generation – Unlike traditional wallets that rely on a device’s RNG (which can be manipulated), AirGap uses device sensors (gyro,touch,mic,camera) and supports manual methods like dice roll and coin flip entropy to generate seed phrases, ensuring verifiable, human-generated randomness for maximum security.
-
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.

Expected Completion Date: Project is already LIVE.
Current Progress (%): AirGap is already live and has established itself as a highly secure solution for self-custody. Building on this strong security foundation, we now aim to expand the wallet-side experience by introducing new features that significantly enhance usability and overall UX. We’ve laid out the roadmap for full TRON integration and the rollout of the agentic layer.

Technical Details
Core functionality
airgap-coin-lib— foundational open-source library: A modular, multi-protocol JS library that handles:
-
Transaction building: Construct raw transactions, inputs, outputs, memos, fees.
-
Cryptographic signing logic: Abstracted across multiple blockchains.
-
Broadcasting: Push signed transactions to blockchain nodes via RPC or HTTP.
Any chain integration begins here, making it portable, reusable, and audit-friendly.
Two-app modular architecture for true air-gapping -
AirGap Vault: Runs on an entirely offline device. Stores private keys, generates secure wallets, and signs transactions using only QR codes — no Bluetooth, USB, or NFC.
AirGap Wallet: Runs on an internet-connected device. Used to create transactions, scan signatures from Vault, broadcast transactions, and interact with dApps.
Together, they ensure private keys never touch an online device, achieving a fully air-gapped flow.
How is the Project Governed?
AirGap is an open-source project, allowing anyone to review, contribute, and improve the codebase. It is currently maintained by Papers AG, ensuring consistent development and high security standards. The project is self-sustaining and relies on ecosystem grants to support new integrations and feature expansion. Over time, it has benefited from contributions by a wide range of developers.
Funding & Business Model
Revenue Model: AirGap is a lean, self-sustaining project with funding secured through previous grants from leading ecosystems such as Polkadot, ICP, Optimism,Rootstock, Tezos, Cosmos, and Stellar. In addition to grant support, AirGap receives community donations and generates revenue through the AirGap Shop, which offers security-focused products like metal backup plates.

Project Milestones
Milestone 1: TRON airgap-coinlib Integration ($10,000)
airGap-coin-lib is the core open-source library that powers the entire AirGap ecosystem.
It acts as the engine that handles transaction creation, signing, and broadcasting for different blockchains. Whenever a new chain is integrated into CoinLib, it automatically becomes compatible with both AirGap Vault (offline cold wallet) and AirGap Wallet (online app).
Because it’s fully open source, third parties can also use coin-lib to build their own wallets or tools for specific chains — without starting from scratch.

Milestone 4: Agentic Integration (Requested Add-on) ($50,000)*
Overview
This milestone extends AirGap’s TRON integration with a native agentic layer — letting users delegate on-chain actions to autonomous agents while preserving AirGap’s core security guarantee: no signing key ever lives on an online device.
Rather than placing an agent key inside the Vault (which would reduce AirGap to a hot wallet with a permission screen), this design uses TRON’s built-in account permission model. The agent operates its own key on its own infrastructure, and the user grants it a scoped Active permission directly on-chain.
The Vault is only involved three times: to grant the permission, to modify scope if needed, and to revoke it. Everything the agent does in between is independent, on-chain, and auditable.
Deliverables
-
OWS Implementation — Full implementation of the Open Wallet Standard agent-facing protocol. TRON is a founding network on OWS, making it the appropriate standard to build against for longevity and ecosystem compatibility.
-
Permission Console — A UI that exposes TRON’s full Active permission model (weights, thresholds, per-operation scoping), not just simplified cases. Users can define exactly what an agent key is and isn’t allowed to do at the protocol level.
-
Vault Grant & Revoke Flow — QR-based signing flows for adding and removing agent keys as Active permissions, with UX designed to make scope unambiguous at the moment of signing.
-
Chain-Event Audit View — A read-only log inside the Wallet that decodes agent activity from on-chain events into human-readable entries. AirGap does not hold or co-sign agent transactions; this view is observational only.
-
Agent-Facing Permission Request Channel — A defined channel through which agents can request permission grants or scope changes, routed to the user for Vault-side approval.
-
Security Review — End-to-end security review of the full agentic flow.
Design Boundaries
AirGap acts as a key and permission manager in this architecture — not the agent runtime. The agent operator is responsible for their own key and infrastructure. TRON’s native Active permissions handle operation-level scoping cleanly. Richer policy enforcement (per-tx value caps, daily spend limits, time-bounded sessions) requires smart account contracts; the TRON contract ecosystem for this is still early, so that enforcement layer is intentionally left as a future plug-in point. The OWS layer is structured to accommodate it without requiring changes to the wallet side when standards mature.
Note: If there are specific commerce flows you want this to land for first (recurring payments, merchant-scoped spend, marketplace agents, whatever else) let us know and we’ll build the permission templates around those rather than guess.
Total Budget Requested - $75,000
Note: AirGap will provide full post-integration support for two years, including maintenance, community engagement, and prompt bug fixes to ensure the integration remains robust and up to date.
Project in 5 Years: Our long-term vision is for AirGap to evolve into a fully self-sustaining, open-source cold wallet solution maintained and continuously improved by a global community of contributors.
