	CallSpec(ctx context.Context, id string, atBlock uint64) (ethcall.Result, error)
}

type EthCallEngine

type EthCallEngine interface {
	MakeResult(specID string, bytes []byte) (ethcall.Result, error)
	CallSpec(ctx context.Context, id string, atBlock uint64) (ethcall.Result, error)
	GetRequiredConfirmations(specId string) (uint64, error)
	StartAtHeight(height uint64, timestamp uint64)
	Start()
