Frequently asked questions

The Blocknative Gas Estimator provides accurate gas fee predictions by analyzing various factors such as the current state of the Ethereum network, the number of pending transactions, and the gas prices in those transactions. It uses historical data and statistical models to calculate the probabilities of different gas fee levels being included in the next block. The estimator takes into account factors such as the priority fee, maximum fee, and the likelihood of different fee levels being accepted. By considering these factors, the Blocknative Gas Estimator provides users with reliable predictions of gas fees for their transactions.

The Blocknative Gas Estimator supports the Ethereum and Polygon networks.

The gas fee probability percentages indicate the likelihood of a particular gas fee being included in a transaction on the Ethereum or Polygon network. For example, if the gas fee has a 80% probability, it means that there is an 80% chance that this gas fee will be included in a transaction. The gas fee is measured in GWEI (Giga-Wei), which is a unit of measurement for gas fees on the Ethereum network.
