Local Gas Estimation
Written by Russo β’ Updated: July 2025
Locanox includes a fully local gas estimator, giving users insight into approximate transaction fees even while offline. Instead of relying on remote APIs or exposing your IP to check gas prices, Locanox runs a compact estimator directly on your device. It uses cached fee data, customizable presets, and a lightweight formula to simulate likely gas requirements across various networks.
This approach allows users to plan transactions, swaps, and contract calls without needing a live internet connection. Whether youβre preparing a batch of offline transactions, building a script, or simply budgeting gas usage, Locanox gives you the privacy-first toolkit to operate confidently.
Offline estimation is never 100% real-time accurate, but itβs fast, private, and safer for those avoiding surveillance or traceable lookups.
β½ How Local Gas Estimation Works
The local gas estimator operates through these key components:
β’ Cached Fee Data
Uses stored historical gas price information to provide realistic estimates without network calls.
β’ Customizable Presets
Allows you to set conservative, standard, or aggressive fee preferences for different transaction types.
β’ Lightweight Formula
Runs efficient calculations on your device to simulate gas requirements across various networks.
β’ Multi-Network Support
Provides estimates for Ethereum, Polygon, and other supported blockchain networks.
β’ Privacy-First Approach
No IP exposure or external API calls - all calculations happen locally on your device.
Benefits of Offline Gas Estimation
- Complete Privacy: No external lookups that could reveal your transaction planning
- Offline Planning: Budget and prepare transactions without internet connectivity
- Fast Calculations: Instant estimates without waiting for network responses
- Customizable Settings: Adjust fee preferences based on your urgency and budget
- Multi-Transaction Support: Plan complex operations involving multiple transactions
While offline estimates may not reflect real-time network conditions, they provide a solid foundation for transaction planning in a completely private environment.
