Types

type SQLiteChainClient

type SQLiteChainClient struct {
	// contains filtered or unexported fields
}

SQLiteChainClient is an eventfeed.ChainClient backed by a persisted history of EVM events in a SQLite database. An EventFeed can be plugged to this backend instead of Alchemy/Infura.

func New

func New(dbURI string, chainID tableland.ChainID) (*SQLiteChainClient, error)

New returns a new *SQLiteChainClient.

func (*SQLiteChainClient) FilterLogs

func (scc *SQLiteChainClient) FilterLogs(ctx context.Context, filter ethereum.FilterQuery) ([]types.Log, error)

FilterLogs returns the logs matching a particular filter.

func (*SQLiteChainClient) HeaderByNumber

func (scc *SQLiteChainClient) HeaderByNumber(ctx context.Context, block *big.Int) (*types.Header, error)

HeaderByNumber returns the block header of the chain. Note that it can only be called with block==nil (i.e: last known block) since the underlying SQLite database isn't a full replication of the underlying chain.
