var DefaultConfig = NewDefaultConfig()

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

var DefaultFullGPOConfig = gasprice.Config{
	Blocks:     20,
	Percentile: 60,
	MaxPrice:   gasprice.DefaultMaxPrice,
}

DefaultFullGPOConfig contains default gasprice oracle settings for full node.

var DefaultLightGPOConfig = gasprice.Config{
