Optionally provide threshold_gwei (number, defaults to 50). Returns: current gas prices (slow/standard/fast in gwei), whether the threshold is breached (alert_triggered), current vs threshold comparison with delta and percentage, estimated transaction costs in gwei/ETH/USD for simple transfers, ERC20 transfers, and DEX swaps, and an actionable recommendation. Use this before submitting transactions to choose optimal timing, to gate automated operations on gas cost, or to monitor network congestion on Base.
