9−We've moved our public-key infrastructure to the Ethereum blockchain. This means
10−that Urbit ship-holders need to generate and secure Ethereum addresses
11−network, and so on. We are using a Type 1 chain of Type 2 hierarchical
12−deterministic (HD) wallets to mirror the affordances of ownership and proxy
13−rights. Our HD wallet solution is described in detail in

9+On-chain Urbit assets can require main different keypairs for operation. To simplify this potentially complex process, we designed our own wallet specification. [This Urbit Proposal](https://github.com/urbit/fora-posts/blob/master/proposals/posts/~2018.11.8..19.31.59..ba77~.md) describes the spec in detail. There are no new cryptographic primitives: it's bascially a Type 2 HD wallet nested inside of a Type 1 HD wallet.
