Why, in full
We compare privacy tools on four things. One of them, how many other people use each tool (25% of the weight), is measured by others, from DefiLlama and L2BEAT, not taken from the vendors. On 27 October 2026 we stopped using both while we ask them for written permission to republish their data, so when we read every tool again on 3 November 2026 that part could not be dated for any of them. For six of the eight tools, the other three things were also read from L2BEAT's privacy pages. We will not rank on a September measure older than our 45-day limit. Until then the tools are listed A to Z.
Not ranked since 6 November 2026. Last checked on 5 November 2026. What brings the ranking back: L2BEAT and DefiLlama give us permission to republish their data, or we count deposits onchain, from each tool's own contracts. Then we read every tool again and rank them.
