透过eth_call 不断模拟买入 直到模拟成功 才去买入， 为什么gasPrice多高还是会慢1个区块。

然后我又改了geth源码,让他模拟的时候把txpool的交易也算进去了。他就直接比开盘的函数快2个区块。如何让我的交易紧跟着开盘的交易走。是要比开盘的交易的gasprice低一点点吗

bsc的geth 修改过的DoCall的源码在这里

func DoCall(ctx context.Context, b Backend, args TransactionArgs, blockNrOrHash rpc.BlockNumberOrHash, overrides *StateOverride, blockOverrides *BlockOverrides, timeout time.Duration, globalGasCap uint64) (*core.ExecutionResult, error) { defer func(start time.Time) { log.Debug("Executing EVM call finished", "runtime", time.Since(start)) }(time.Now()) state, header, err := b.StateAndHeaderByNumberOrHash(ctx, blockNrOrHash) if state == nil || err != nil { return nil, err } pendingTxs, err := b.GetPoolTransactions() if err != nil { return nil, err } tmpStatedb := state.Copy() for _, tx := range pendingTxs { if tx.To() == args.To { msg, err := core.TransactionToMessage(tx, types.LatestSigner(b.ChainConfig()), header.BaseFee) if err != nil { return nil, err } txCtx := core.NewEVMTxContext(msg) context := core.NewEVMBlockContext(header, NewChainContext(ctx, b), nil) evm := vm.NewEVM(context, txCtx, tmpStatedb, b.ChainConfig(), vm.Config{NoBaseFee: true}) _, err = core.ApplyMessage(evm, msg, new(core.GasPool)) if err != nil { return nil, err } } else { continue } } return doCall(ctx, b, args, tmpStatedb, header, overrides, blockOverrides, timeout, globalGasCap) }

python中大概的实现就是:

def simulate(): eth_call(xxxx) def main(): while 1: if simulate == True: 买入
