I will discuss the recent progress towards renormalizing the Standard Model effective field theory to order (v/f)^4, with v being the electroweak scale and f the new physics threshold, that we have made using diagrammatic techniques off-shell. I will also discuss the interplay with amplitude methods and positivity bounds.
Likewise, I will elaborate on how we have dealt with difficulties such as removing (unphysical) interactions that vanish upon using appropriate field redefinitions.
Based on: 2106.05291, 2205.03301, 2409.15408.
