Appendix - MetaMask

Custom Network Over pricing

Metamask will pad the estimated gas without exceeding the most recent block gasLimit. However, If the network is a a custom network it will return the eth_estimateGas value

    "In this Systematization of Knowledge (SoK) we delineate the various EVM gas pricing API's along the following axes: its reported data, its 
    data types, latency, and accuracy of pricing transactions within specified intervals. 
    We provide a distinction between technical accuracy and economic accuracy for these transaction pricing API's. Finally, we provide an 
    ongoing comparison of these pricing API providers both on reported precision and accuracy of their services."
