  We discuss possible implications of Exotic Stringy instantons for
Baryon-violating signatures in future colliders. In particular, we discuss
high-energy quarks collisions and $\Lambda-\bar{\Lambda}$ transitions. In
principle, $\Lambda-\bar{\Lambda}$ process can be probed by high-luminosity
electron-positron colliders. However, we find that an extremely high luminosity
is needed in order to provide a (somewhat) stringent bound compared to the
current data on $NN\rightarrow \pi\pi,KK$. On the other hand, (exotic)
instanton-induced six quark interactions can be tested in near future
high-energy colliders beyond LHC, at energies around $20-100\, \rm TeV$. Super
proton-proton collider (SppC) is capable of such measurement given the proposed
energy level of 50-90 TeV. Comparison with other channels is made. In
particular, we show the compatibility of our model with neutron-antineutron and
$NN\rightarrow \pi\pi,KK$ bounds.
