x711_tx_simulate

Active

Tool of x711 — Universal Agent Gas Station

declared in 1.0.0

Simulate an on-chain transaction on Base, Ethereum, Arbitrum, Optimism, Polygon, BNB Smart Chain (bnb/bsc), or opBNB L2 BEFORE broadcasting. Uses public RPC eth_call + eth_estimateGas — no wallet or API key needed. Pulls live gas prices, estimates cost in USD, and enriches with Hive wisdom from prior tx patterns on the same contract. Always simulate before calling x711_tx_broadcast. Returns: { success: bool, simulation.result, gas.estimate, gas.cost_usd, hive_wisdom, next_step }. Free tier: 3 sims/day (no API key needed).
