I would love to know some more on this, I haven't been able to find these articles, specifically about the security flaws of the SeedSigner device (https://github.com/SeedSigner/seedsigner) in relation to not having a Secure Element chip . Specifically since the Secure Element chip is designed to store the "secure element" (in other words, the seed). And this is something which SeedSigner does not do. It is a stateless device.
