I will discuss the integrability and wall-crossing properties of Kondo line defects in rational conformal field theories. It provides a large class of interesting defect RG flow deforming from topological line defects. As a surprise, we found new examples of the ODE /IM correspondence, based on which we can predict the IR fate of the nonperturbative Kondo RG flows. This work is part of a multi-pronged exploration of studying four-dimensional Chern-Simons theory as an overarching structure for integrable systems.
