Description
Geth shipped a breaking change which did the following.
valueirrespective of their ETH balanceThese two combination results in an insufficient funds as not even Vitalik has enough funds for 50 gwei @ MaxUint64 gas limit.
As a result we either need to drop (or lower) gas price to 1 wei, resulting in the user requiring 18 ETH for validation. We want to validate the gas price and protocol fee, so we cannot drop the gas price entirely. So this is out.
So we need to either fix the gas limit to something reasonable in the case we're performing a validation (eth call with ?? gas). Or we perform the Estimate gas first then the
eth_call, unable to parallelize.In
/swap/v0/quotewe have opted to remove the parallelization and first perform the estimate then the call.In MetaTxn we have opted to fix the gas limit to 10e6 as we do not yet have a signer. The reason we wanted to perform them in parallel is for speed and to reveal the
eth_callerror, not the gas estimation error.
