Gas Fee Tracker

用 Python 脚本调用公共 RPC 节点，查询 Ethereum、Base、Polygon、Arbitrum 实时 gas 价格，按各链阈值分为低/中/高，可输出 JSON、追加 JSONL 历史，并以退出码供自动化按阈值判断。仅取 legacy gasPrice，不含 EIP-1559 拆解或预测。

Metadata

name: gas-fee-tracker
description: Track live EVM gas fees across Ethereum, Base, Polygon, and Arbitrum using free public RPC endpoints with no API key required. Classifies current gas as low, medium, or high against configurable thresholds, logs snapshots to a JSONL history file over time, and supports threshold alerts for scripting into automations. Useful for crypto trading, defi, smart contract deployment, and passive income bots that need to time on-chain transactions to avoid overpaying for gas. Complements whale-tracking and defi yield-farming workflows by timing execution around cheap gas windows.

Gas Fee Tracker

Live gas price snapshots across four EVM chains, using only free public RPC endpoints — no API key, no rate-limit signup required.

When to use this skill

Timing a contract deployment or large transaction batch for a cheap gas window
Building an automation that only executes a transaction when gas drops below a threshold
Logging gas price history over time to spot patterns (e.g. daily/weekly cycles) before scheduling recurring on-chain jobs

How to use it

Snapshot all chains:

python3 scripts/gas_tracker.py

Single chain, JSON output for scripting:

python3 scripts/gas_tracker.py --chain ethereum --json

Append to a running history log:

python3 scripts/gas_tracker.py --log gas_history.jsonl

Use as a gate in an automation (exits 0 only if gas is at/below threshold):

python3 scripts/gas_tracker.py --chain base --alert-below 0.1 && echo "cheap gas, proceed"

Supported chains

Ethereum mainnet, Base, Polygon, Arbitrum One — each with its own low/high gwei thresholds tuned to that chain's typical range.

Limitations

Reports the current eth_gasPrice legacy gas price, not EIP-1559 base-fee/priority-fee breakdown or a predictive estimate of future blocks
Public RPC endpoints can occasionally rate-limit or time out; the script reports per-chain errors rather than failing the whole run
