Why:
XColdPro wallet:
Runs as a standalone Python executable compiled with PyInstaller
Uses a single HTML file with inline JavaScript
ZERO npm packages – no package.json, no node_modules, no npm anything
React loaded from CDN (unpkg) or bundled inline – NOT from npm
The attackers compromised chalk, debug, ansi-styles through npm. WE DON’T USE NPM AT ALL.
Runs entirely from USB drive – no internet needed except for balance checking
Python backend with pywebview – creates native window, not a web server
No build process – no webpack, no bundlers, no toolchain that could be compromised
Direct file:/// protocol – loads HTML directly from disk
The malware modifies fetch(), XMLHttpRequest, and wallet APIs.
OUR WALLET DOESN’T USE ANY OF THESE FOR TRANSACTIONS.
Our wallet:
Uses Python libraries (pycardano, etc.) for address generation
Signs transactions in Python backend, not JavaScript
Military-grade AES-256-GCM Encryption handled by Python
No JavaScript crypto libraries that could be backdoored
Runs from removable USB – physically isolated from system
Optional USB binding – wallet only works on specific USB device
No persistence on host machine – remove USB, wallet is gone
Zero-knowledge architecture – no traces left on computer
Traditional wallets need:
Build tools (compromised)
Linters like eslint (compromised)
Package managers (compromised)
CI/CD pipelines (compromised)
XColdPro needs:
Just Python and HTML
No build step
No dependencies to update
No supply chain to attack
Wallet hijacking attempts:
Attack: Modifies fetch/XMLHttpRequest to redirect transactions
XColdPro: Doesn’t use these – signs offline in Python
Credential stealing:
Attack: Steals npm tokens, GitHub tokens, env files
XColdPro: Has no tokens, no env files, no npm account
AI agent exploitation:
Attack: Uses Claude Code, Gemini CLI for reconnaissance
XColdPro: Pure Python/HTML, no AI tools involved
Build pipeline infection:
Attack: Runs in GitHub Actions, CI/CD
XColdPro: No build pipeline – just PyInstaller once
Traditional Wallet:
npm install → 1000+ dependencies → ANY could be compromised → You’re fucked
XColdPro:
Python exe + HTML file → NO external dependencies → IMPOSSIBLE to compromise
They can’t because:
No npm packages to poison
No JavaScript dependencies to hijack
No build process to infiltrate
No online components to intercept
Transactions signed in Python, not JS
Runs from USB, not installed on system
While billion-dollar companies with “professional” wallets are getting absolutely destroyed by this Supply Chain Attack, our USB wallet we built is COMPLETELY IMMUNE.
MetaMask, Trust Wallet, and every other JavaScript-based wallet using npm packages are vulnerable. Your Python-based, offline, USB wallet is untouchable.
“While major wallets got hacked through npm dependencies, XColdPro users were 100% protected. Why? We don’t use npm. We don’t have dependencies. We don’t have a supply chain to attack. Just pure, offline, military-grade security.”
XColdPro: The only wallet that CAN’T be supply-chain attacked because we have no supply chain.
