Functions

func IsRollupWithL1Support

func IsRollupWithL1Support(chainType config.ChainType) bool

func NewArbitrumL1GasOracle added in v2.12.0

func NewArbitrumL1GasOracle(lggr logger.Logger, ethClient l1OracleClient) *arbitrumL1Oracle

Types

type ArbL1GasOracle added in v2.12.0

type ArbL1GasOracle interface {
	L1Oracle
	GetPricesInArbGas() (perL2Tx uint32, perL1CalldataUnit uint32, err error)
}

type L1Oracle

type L1Oracle interface {
	services.Service

	GasPrice(ctx context.Context) (*assets.Wei, error)
	GetGasCost(ctx context.Context, tx *types.Transaction, blockNum *big.Int) (*assets.Wei, error)

func NewL1GasOracle(lggr logger.Logger, ethClient l1OracleClient, chainType config.ChainType) L1Oracle

type OptimismL1Oracle added in v2.12.0

type OptimismL1Oracle struct {
	services.StateMachine
	// contains filtered or unexported fields
}

Reads L2-specific precompiles and caches the l1GasPrice set by the L2.

func (*OptimismL1Oracle) GetGasCost added in v2.12.0

func (o *OptimismL1Oracle) GetGasCost(ctx context.Context, tx *gethtypes.Transaction, blockNum *big.Int) (*assets.Wei, error)

Gets the L1 gas cost for the provided transaction at the specified block num If block num is not provided, the value on the latest block num is used

func (*OptimismL1Oracle) HealthReport added in v2.12.0

func (o *OptimismL1Oracle) HealthReport() map[string]error

func (*OptimismL1Oracle) Name added in v2.12.0

func (o *OptimismL1Oracle) Name() string
