Types

type Client

type Client interface {
	// BlockNumber returns the current block number.
	BlockNumber(ctx context.Context) (*big.Int, error)

	// Block returns the block data. The block number can be changed by using
	// the WithBlockNumber context.
	Block(ctx context.Context) (*types.Block, error)

	// Call executes a message call transaction, which is directly
	// executed in the VM of the node, but never mined into the blockchain.
	Call(ctx context.Context, call types.Call) ([]byte, error)

	// CallBlocks executes the same call on multiple blocks (counting back from the latest)
	// and returns multiple results in a slice
	CallBlocks(ctx context.Context, call types.Call, blocks []int64) ([][]byte, error)

	// MultiCall works like the Call function but allows to execute multiple
	// calls at once.
	MultiCall(ctx context.Context, calls []types.Call) ([][]byte, error)

	// Storage returns the value of key in the contract storage of the
	// given account.
	Storage(ctx context.Context, address types.Address, key types.Hash) ([]byte, error)

	// Balance returns the wei balance of the given account.
	Balance(ctx context.Context, address types.Address) (*big.Int, error)

	// SendTransaction injects a signed transaction into the pending pool
	// for execution.
	SendTransaction(ctx context.Context, transaction *types.Transaction) (*types.Hash, error)

	// FilterLogs executes a filter query.
	FilterLogs(ctx context.Context, query types.FilterLogsQuery) ([]types.Log, error)
}
