Gas Estimation API

by Blocknative

Gas Platform harnesses real-time global mempool data infrastructure to accurately and consistently estimate Ethereum transaction fees. This provides builders & traders with an up-to-the-moment gas fee API.

Blocknative's Gas Estimation RPC leverages Blocknative's real-time global mempool data platform to inspect all public pending Ethereum or Polygon transactions to accurately predict the minimum gas price required for next-block confirmation. Blocknative's Gas Estimation RPC uses an advanced machine learning model to accurately predict gas prices and makes predictions based on block number rather than time. The RPC endpoint will return gas estimation confidence levels, giving you and your users precise control over transaction fees.
