Cryptography

The underlying cryptography / keystore for Gem Wallet is implemented using Trust Wallet Core for now.

    client-- pricing, notification and ... -->core-lib
    client-- cryptography such as seed generation and ... -->trust-core

Note: According to the roadmap, in the future, the client will only interact with the Gem Wallet Core, and the interaction with the Trust Wallet Core will be the responsibility of the Gem Wallet Core.
