PROJECT: Standardized Hardware API for Cryptographic Interoperability

**The Problem:** as a developer, have to learn the APIs for a number of different hardware devices; as a user, you have the NASCAR problem of a list of providers. Worse, if any individual company changes their API, then everything breaks.

**The Solutions:** Develop a uniform API and architecture with relatively few commands, with capability-discovering on error that help to answer the hardware and network side of things.

- [ ] Analyze Patterns
- [ ] Define Goals of Principals
- [ ] Define Overall Architecture for Standard Wallet API
- [ ] Integrate with SSKR Recovery
- [ ] Update crypto-requests as Needed
- [ ] Update Other URs as Needed
- [ ] Write Draft of Paper for Ideal API
- [ ] Update [Wallet Architecture Diagram and Article](https://github.com/WebOfTrustInfo/rwot9-prague/blob/master/topics-and-advance-readings/whats-wallet.md) (see #90)
- [ ] Implement MVP of API

- [ ] Evangelize to community

This is expected to be a joint project of Blockchain Commons, CrossBar, and Proxy.

Comienza leyendo el borrador enlazado de Hardware Wallet Use Cases y la hoja de cálculo Crypto API Analysis; después, revisa el Wallet Architecture Diagram y el artículo referenciado con #90. Este issue solo estará terminado cuando se hayan definido la arquitectura, el borrador de la API, el MVP, la documentación y el despliegue para la comunidad del proyecto, y la checklist esté completa.
