Case Study: GasHawk protects users’ funds and saves on gas fees with Tenderly Simulation API

How GasHawk Brings More Value to Users With Transaction Simulations

GasHawk is a straightforward Ethereum gas-saving platform that helps users queue signed transactions and send them when fees are low. Its challenge was dealing with volatile gas prices, stuck transactions, and the need to provide more value and reassurance to a technical user base. To address this, GasHawk used Tenderly’s Simulation API to preview transactions before they were sent on-chain.

With Tenderly, GasHawk can simulate pending transactions, estimate actual gas usage, warn users about failed or undesirable outcomes, and let users inspect execution details. The result is a better user experience, stronger protection for user funds, and added confidence for technical users. GasHawk also reported measurable savings of around 30% on gas fees on average, with over 90% in high-volatility periods and 10–20% even during lower-fee times.
