Coldstar Data Room

The Problem

Hardware wallets cost $50–$300, suffer from supply chain vulnerabilities and data breaches, and lock users into vendor-specific ecosystems. This blocks DAOs, traders, and developers from using cold security in practice.

The Solution

Coldstar turns any standard USB drive into an air-gapped cold wallet. No vendor, no supply chain risk, no $200 device. Security lives in the cryptography and the physical air gap — not in a brand name.

Step 01

Prepare

Flash any USB drive into
a hardware wallet

→

Step 02

Transport

Carry the transaction file
via the USB drive

→

Step 03

Sign

Boot the CLI on an air-gapped
machine and sign

Security Model

Ed25519 signing with RAM-only key exposure. Keys are never written to persistent storage. The physical air gap ensures no network-based attack vector exists.

Target Users

DAOs needing treasury management, traders handling high-value transfers, and developers building CLI-first tooling. Workshop-driven onboarding via Superteam global network.

Competitive Edge

Zero hardware cost. No vendor dependency. No supply chain attack surface. First transaction signed in minutes with guided CLI flow. 35% of wallets remain actively signing.

Technical Architecture

Coldstar is a multi-language, multi-repo infrastructure project spanning cryptographic signing, on-chain programs, CLI tooling, and developer SDKs.

Repositories

Acquisition Channel

Superteam global workshop rollout. Build-your-own wallet sessions. CLI-first tooling and GitHub tutorials. DAO treasury onboarding for high-value users.

Onboarding

First transaction signed within minutes via guided CLI flow. Hands-on workshop execution. Zero drop-off after initial setup — users complete their first signing in the session.

Retention Signal

37% of wallets are still actively signing after creation. Trust stems from RAM-only key exposure and no persistent secrets. High-value usage: treasury ops, large transfers, staking.

Revenue Model

1% Transaction Fee (capped at $10)

Primary revenue engine. Per-transaction fee on signed operations, with a hard cap to keep pricing fair for high-value transfers. Aligns incentives with usage growth.

Jito Tips from Staked Solana

MEV yield sharing through Jito partnership. Revenue generated from staked Solana positions managed through Coldstar infrastructure.

Native RWA Swaps & Transfers

Revenue from real-world asset operations executed through Coldstar. Multichain RWA support on the roadmap for Q3 2026.

Growth Engine

Weekend project to blue chip standard. A four-stage flywheel turning workshops into DAO-scale adoption.
