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)
	// LatestFinalizedBlockNumber returns the latest finalized block number
	LatestFinalizedBlockNumber(ctx context.Context, confirmations uint64) (*big.Int, error)
	// Close closes the client connection
	Close()
}

Client provides calls to EVM JSON-RPC endpoints

func NewClient

func NewClient(url string, override FinalityOverride) (Client, error)

NewClient returns an EVM JSON-RPC client

type Ethereum2Client

type Ethereum2Client struct {
	*EthereumClient
}

Ethereum2Client is a JSON-RPC client of Ethereum 2.0

func NewEthereum2Client

func NewEthereum2Client(ethereumClient *EthereumClient) (*Ethereum2Client, error)

NewEthereum2Client is the constructor

func (*Ethereum2Client) LatestFinalizedBlockNumber

func (c *Ethereum2Client) LatestFinalizedBlockNumber(ctx context.Context, _ uint64) (*big.Int, error)

LatestFinalizedBlockNumber returns the latest finalized block number

type EthereumClient

type EthereumClient struct {
	EthereumJSONRPCClient
	// contains filtered or unexported fields
}
