A primary weakness is that if the seed is leaked, all funds are compromised, and wallet sharing is extremely limited. {% endautocrossref %} #### Type 2: Hierarchical Deterministic (HD) Wallets {% autocrossref %} ![Overview Of Hierarchical Deterministic Key Derivation](/img/dev/en-hd-overview.svg) For an overview of HD wallets, please see the [developer guide section][devguide wallets].
