Types

type Chain

type Chain struct {
	// contains filtered or unexported fields
}

Chain represents a blockchain with a unique Chain ID

func ChainFromID

func ChainFromID(id *big.Int) *Chain

ChainFromID returns the chain for the given ID If no chain is found, creates a new one and returns that

func (*Chain) Config

func (c *Chain) Config() ChainSpecificConfig

func (*Chain) ID

func (c *Chain) ID() *big.Int

func (*Chain) IsArbitrum

func (c *Chain) IsArbitrum() bool

IsArbitrum returns true if the chain is arbitrum

func (*Chain) IsL2

func (c *Chain) IsL2() bool

IsL2 returns true if this chain is an L2 chain. Notably the block numbers used for log searching are different from calling block.number

func (*Chain) IsOptimism

func (c *Chain) IsOptimism() bool

IsOptimism returns true if the chain is optimism

type ChainSpecificConfig

type ChainSpecificConfig struct {

ChainSpecificConfig lists the config defaults specific to a particular chain ID

var FallbackConfig ChainSpecificConfig

FallbackConfig represents the "base layer" of config defaults It can be overridden on a per-chain basis and may be used if the chain is unknown
