Hypernorm is a generalization of the notion of a norm on a vector space over a field. In this paper, we consider a hypervector space $$(\mathbb {V}, +)$$
(
V
,
+
)
over a hyperfield, where $$+$$
+
is a hyperoperation, and prove that the hypernorm is continuous. We show that the natural linear transformation from $$\mathbb {V}$$
V
to $$\dfrac{\mathbb {V}}{Z}$$
V
Z
is continuous and open for all closed subhyperspaces Z of $$\mathbb {V}$$
V
. We prove $$BL(\mathbb {V},\mathbb {W}),$$
B
L
(
V
,
W
)
,
the set of all bounded linear transformations from $$\mathbb {V}$$
V
to $$\mathbb {W}$$
W
is a hyper-Banach space whenever $$\mathbb {W}$$
W
is complete. Furthermore, we obtain that in a hyper-Banach space $$\mathbb {V}$$
V
if $$\lbrace \mu _n \rbrace$$
{
μ
n
}
is a sequence of continuous linear transformations with $$\lbrace /\mu _n(u)/ \rbrace$$
{
/
μ
n
(
u
)
/
}
is bounded for every $$u \in \mathbb {V},$$
u
∈
V
,
then $$\lbrace \Vert \mu _n\Vert \rbrace$$
{
‖
μ
n
‖
}
is bounded. In the sequel, we prove several properties of hypernorm and linear transformations on hypernormed spaces.
