func (n *FnTracer) OnPublishL2Payload(ctx context.Context, payload *eth.ExecutionPayload)

func (*FnTracer) OnUnsafeL2Payload

func (n *FnTracer) OnUnsafeL2Payload(ctx context.Context, from peer.ID, payload *eth.ExecutionPayload)

type GethOption

type GethOption func(ethCfg *ethconfig.Config, nodeCfg *node.Config) error

type KromaGeth

type KromaGeth struct {
	L2Client      *ethclient.Client
	SystemConfig  eth.SystemConfig
	L1ChainConfig *params.ChainConfig
	L2ChainConfig *params.ChainConfig
	L1Head        eth.BlockInfo
	L2Head        *eth.ExecutionPayload
	// contains filtered or unexported fields
}

KromaGeth is an actor that functions as a l2 kroma-geth node It provides useful functions for advancing and querying the chain

func NewKromaGeth

func NewKromaGeth(t *testing.T, ctx context.Context, cfg *SystemConfig) (*KromaGeth, error)

func (*KromaGeth) AddL2Block

func (d *KromaGeth) AddL2Block(ctx context.Context, txs ...*types.Transaction) (*eth.ExecutionPayload, error)

AddL2Block Appends a new L2 block to the current chain including the specified transactions The L1Info transaction is automatically prepended to the created block

func (*KromaGeth) Close

func (d *KromaGeth) Close()

func (*KromaGeth) CreatePayloadAttributes

func (d *KromaGeth) CreatePayloadAttributes(txs ...*types.Transaction) (*eth.PayloadAttributes, error)

CreatePayloadAttributes creates a valid PayloadAttributes containing a L1Info deposit transaction followed by the supplied transactions.

func (*KromaGeth) StartBlockBuilding

func (d *KromaGeth) StartBlockBuilding(ctx context.Context, attrs *eth.PayloadAttributes) (*eth.ForkchoiceUpdatedResult, error)

StartBlockBuilding begins block building for the specified PayloadAttributes by sending a engine_forkChoiceUpdated call. The current L2Head is used as the parent of the new block. ErrForkChoiceUpdatedNotValid is returned if the forkChoiceUpdate call returns a status other than valid.
