For people using GrapheneOS on an 8th generation Pixel, there is another compelling reason to use Vanadium: GrapheneOS (@GrapheneOS): "Our Vanadium browser is also the first browser using MTE in production. In Vanadium, we enable Chromium's PartitionAlloc MTE implementation. PartitionAlloc's implementation isn't nearly as good as hardened_malloc, but we intend to improve PartitionAlloc's security in the future." | nitter
Chromium marks itself as compatible with MTE but then disables it as runtime, so other Chromium-based browser have MTE disabled even when the OS has it enabled.
The benefits of MTE are summarized in a comment from a different thread: Write about MTE (Android) - #6 by anon28734771
