FT4 accounts configuration

This section guides you through installing the FT4 library and configuring your accounts.

Install the FT4 library​

Before diving into account configuration, you need to install the FT4 library to manage accounts effectively. Add the following code to your chromia.yml file:

chromia.yml
libs:
  ft4:
    registry: https://gitlab.com/chromaway/ft4-lib.git
    path: rell/src/lib/ft4
    tagOrBranch: v1.1.0r
    rid: x"FEEB0633698E7650D29DCCFE2996AD57CDC70AA3BDF770365C3D442D9DFC2A5E"
    insecure: false
  iccf:
    registry: https://gitlab.com/chromaway/core/directory-chain
    path: src/lib/iccf
    tagOrBranch: 1.87.0
    rid: x"9C359787B75927733034EA1CEE74EEC8829D2907E4FC94790B5E9ABE4396575D"
    insecure: false

Configure FT4 accounts​

In this app, you will add FT4 accounts to your model, enhancing your authentication mechanism.

Start by importing the necessary modules:

src/registration/module.rell
import lib.ft4.core.accounts.{ account, single_sig_auth_descriptor, create_account_with_auth };

Next, define an account within the user entity:

src/news_feed/model.rell
entity user {
  mutable name;
  key id: byte_array;
  key account;
}

This setup enforces a one-to-one mapping between an FT4 account and a user. Now, modify the create_user operation to also create an FT4 account:

src/registration/module.rell
operation register_user(name) {
    val account = register_account();
    val user = create user ( name, account.id, account );
    create follower ( user = user, follower = user );
}

For detailed information on account permissions and the FT4 framework, refer to the FT4 Accounts and Tokens documentation.

Next, move the test section under the blockchain tag in your chromia.yml and add the admin public key:

chromia.yml
blockchains:
  my_news_feed:
    module: main
    test:
      modules:
        - test
    moduleArgs:
      lib.ft4.core.admin:
        admin_pubkey: x"023BEE5A479CE5AF31F6F64EDE7BEAD394E92E4D973E1727782DB577A55E878563"

libs:
  ft4:
    registry: https://gitlab.com/chromaway/ft4-lib.git
    path: rell/src/lib/ft4
    tagOrBranch: v1.1.0r
    rid: x"FEEB0633698E7650D29DCCFE2996AD57CDC70AA3BDF770365C3D442D9DFC2A5E"
    insecure: false
  iccf:

    tagOrBranch: 1.87.0
