Variables

var DefaultConfig = NewDefaultConfig()

DefaultConfig contains default settings for use on the Metal main net.

var DefaultFullGPOConfig = gasprice.Config{
	Blocks:              40,
	Percentile:          60,
	MaxLookbackSeconds:  gasprice.DefaultMaxLookbackSeconds,
	MaxCallBlockHistory: gasprice.DefaultMaxCallBlockHistory,
	MaxBlockHistory:     gasprice.DefaultMaxBlockHistory,
	MinPrice:            gasprice.DefaultMinPrice,
	MaxPrice:            gasprice.DefaultMaxPrice,
	MinGasUsed:          gasprice.DefaultMinGasUsed,

DefaultFullGPOConfig contains default gasprice oracle settings for full node.
