When a crypto wallet says it\u2019s \u201copen source,\u201d it basically means anyone can look at the code. But that doesn\u2019t automatically mean someone has checked it, or that the app on your phone was actually built from that exact code. Reproducible builds give you a way to check that the two match. The catch is that doing this verification yourself can be quite technical and time-consuming, much more work than the simple \u201copen source\u201d label might suggest.<\/p>\n\n\n\n
