Crypto users need to know current transaction fees across multiple blockchains to time their transactions when network fees are low, saving money on gas costs

User clicks extension icon → popup displays current gas prices across selected blockchain networks fetched from public RPC nodes and APIs → user checks fees and decides optimal time to transact

Target users: Cryptocurrency traders and DeFi users / Blockchain developers / Anyone making on-chain transactions who wants to optimize gas costs

Source code is heavily minified (single-line JS files), making deeper logic analysis difficult
Cannot fully verify if ct.app parent service offers paid tools that this extension links to
Cannot confirm if popup.js contains any hidden paid feature gating due to minification

Monetization

No paid features detected

No payment processing, subscription management, premium gating, or billing APIs found. The 'subscribe' hit is generic HTTP library code. 'pro' hits are CSS class names and Vue template boilerplate, not premium features. 'license' hits are MIT/public domain license declarations. No Stripe, PayPal, or other payment platform integration detected.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: No
Reason: No login UI, authentication endpoints, or account creation flow found. The extension queries public blockchain RPC nodes and block explorers directly without requiring user credentials. 'token' hits refer to cryptocurrency tokens, not auth tokens; 'auth' hit is from axios HTTP library internals; 'account' hit is from cookie utility code.
