Types

type Client

type Client interface {
	// TransactionReceipt returns the transaction receipt for the given transaction hash
	TransactionReceipt(ctx context.Context, txHash common.Hash) (*types.Receipt, error)
	// HeaderByNumber returns the block header for the given block number
	HeaderByNumber(ctx context.Context, number *big.Int) (*Header, error)
	// IsFinalized determines whether or not the given transaction receipt is finalized on the chain
	IsFinalized(ctx context.Context, conf uint64, txReceipt *types.Receipt) (bool, error)
	// Close closes the client connection
	Close()
}

Client provides calls to EVM JSON-RPC endpoints

func NewClient

func NewClient(url string) (Client, error)

NewClient returns an EVM JSON-RPC client

func NewL2Client

func NewL2Client(chain string, url string, l1Client Client) (Client, error)

NewL2Client returns a L2 EVM JSON-RPC client

type Header

type Header struct {
	ParentHash    common.Hash    `json:"parentHash"       gencodec:"required"`
	Number        *hexutil.Big   `json:"number"           gencodec:"required"`
	Time          hexutil.Uint64 `json:"timestamp"        gencodec:"required"`
	Hash          common.Hash    `json:"hash"`
	Transactions  []common.Hash  `json:"transactions"     gencodec:"required"`
	L1BlockNumber *hexutil.Big   `json:"l1BlockNumber"`
}

Header represents a block header in any EVM blockchain

type MoonbeamHeader

type MoonbeamHeader struct {
	ParentHash     common.Hash  `json:"parentHash"       gencodec:"required"`
	ExtrinsicsRoot common.Hash  `json:"extrinsicsRoot"   gencodec:"required"`
	StateRoot      common.Hash  `json:"stateRoot"        gencodec:"required"`
	Number         *hexutil.Big `json:"number"           gencodec:"required"`
}

MoonbeamHeader represents a block header in the Moonbeam blockchain
