const (
	Wei   = 1
	GWei  = 1e9
	Ether = 1e18
)

These are the multipliers for ether denominations. Example: To get the wei value of an amount in 'gwei', use 

new(big.Int).Mul(value, big.NewInt(params.GWei))

Functions

func GetExtra added in v0.7.4 

func GetExtra(c *ChainConfig) *extras.ChainConfig

func GetRulesExtra added in v0.7.4 

func GetRulesExtra(r Rules) *extras.Rules

func SetEthUpgrades added in v0.7.4 

func SetEthUpgrades(c *ChainConfig) error

SetEthUpgrades enables Ethereum network upgrades using the same time as the Avalanche network upgrade that enables them.

TODO: Prior to Cancun, Avalanche upgrades are referenced inline in the code in place of their Ethereum counterparts. The original Ethereum names should be restored for maintainability.

func SetNetworkUpgradeDefaults added in v0.7.4 

func SetNetworkUpgradeDefaults(c *ChainConfig)

func VersionWithCommit added in v0.2.5 

func VersionWithCommit(gitCommit, gitDate string) string

Types

type ChainConfig 

type ChainConfig = ethparams.ChainConfig

ChainConfig is the core config which determines the blockchain settings.

ChainConfig is stored in the database on a per block basis. This means that any network, identified by its genesis block, can have its own set of configuration options.

func Copy added in v0.7.4 

func Copy(c *ChainConfig) ChainConfig

func WithExtra added in v0.7.4 

func WithExtra(c *ChainConfig, extra *extras.ChainConfig) *ChainConfig

WithExtra sets the extra payload on `c` and returns the modified argument.

type ChainConfigWithUpgradesJSON added in v0.4.12 

type ChainConfigWithUpgradesJSON struct {
	ChainConfig
	UpgradeConfig extras.UpgradeConfig `json:"upgrades,omitempty"`
}

func ToWithUpgradesJSON added in v0.7.4 

func ToWithUpgradesJSON(c *ChainConfig) *ChainConfigWithUpgradesJSON

ToWithUpgradesJSON converts the ChainConfig to ChainConfigWithUpgradesJSON with upgrades explicitly displayed. ChainConfig does not include upgrades in its JSON output. This is a workaround for showing upgrades in the JSON output.

func (ChainConfigWithUpgradesJSON) MarshalJSON added in v0.4.12 

func (cu ChainConfigWithUpgradesJSON) MarshalJSON() ([]byte, error)

MarshalJSON implements json.Marshaler. This is a workaround for the fact that the embedded ChainConfig struct has a MarshalJSON method, which prevents the default JSON marshalling from working for UpgradeConfig. TODO: consider removing this method by allowing external tag for the embedded ChainConfig struct.

func (*ChainConfigWithUpgradesJSON) UnmarshalJSON added in v0.4.12 

func (cu *ChainConfigWithUpgradesJSON) UnmarshalJSON(input []byte) error

type Rules 

type Rules = ethparams.Rules

Rules wraps ChainConfig and is merely syntactic sugar or can be used for functions that do not have or require information about the block.

Rules is a one time interface meaning that it shouldn't be used in between transition phases.

type RulesExtra added in v0.7.4 

type RulesExtra extras.Rules

func (RulesExtra) ActivePrecompiles added in v0.7.4 

func (RulesExtra) ActivePrecompiles(existing []common.Address) []common.Address

func (RulesExtra) CanCreateContract added in v0.7.4 

func (r RulesExtra) CanCreateContract(ac *libevm.AddressContext, gas uint64, state libevm.StateReader) (uint64, error)

func (RulesExtra) CanExecuteTransaction added in v0.7.4 

func (RulesExtra) CanExecuteTransaction(common.Address, *common.Address, libevm.StateReader) error

func (RulesExtra) MinimumGasConsumption added in v0.7.5 

func (RulesExtra) MinimumGasConsumption(x uint64) uint64

MinimumGasConsumption is a no-op.

func (RulesExtra) PrecompileOverride added in v0.7.4 

func (r RulesExtra) PrecompileOverride(addr common.Address) (libevm.PrecompiledContract, bool)
