Setting up Your Project

Create Environment

To start, run the command

chr create-rell-dapp my-first-project

To install chr command, check here.

Navigate into the folder

cd my-first-project/

You can now open the project in your favorite IDE.

Project Structure

A typical Yours Protocol project follows the standard Chromia project structure:

your-dapp/
├── chromia.yml           # Project configuration
├── src/
│   ├── modules/
│   │   ├── your_module_a/    # Your custom modules
│   │   ├── your_module_b/    # Your custom modules
│   ├── libs/             # Your dependencies
│   │   ├── ft4/          # FT4 library
│   │   ├── iccf/         # ICCF library
│   │   └── yours/        # Yours Protocol library
│   └── main.rell         # Main application file

Dependencies

Yours Protocol has two dependencies in order to be interoperable with other blockchains and dapps:

• FT4 - Account management system for handling token ownership and transfers

• ICCF - Inter-Chain Communication Facility for cross-chain bridging and token interoperability

Add the following libraries to your chromia.yaml:

libs:
  ft4:
    registry: https://gitlab.com/chromaway/ft4-lib.git
    path: rell/src/lib/ft4
    tagOrBranch: v1.0.0r
    rid: x"FA487D75E63B6B58381F8D71E0700E69BEDEAD3A57D1E6C1A9ABB149FAC9E65F"
    insecure: false
  iccf:
    registry: https://gitlab.com/chromaway/core/directory-chain
    path: src/iccf
    tagOrBranch: 1.32.2
    rid: x"1D567580C717B91D2F188A4D786DB1D41501086B155A68303661D25364314A4D"
    insecure: false
  yours:
    registry: https://github.com/megayours/yours-protocol.git
    path: src/lib/yours
    tagOrBranch: main
    rid: x"441DC91E16929A8929EE06D6FCB80183E3561FB08BA760EF14371B3E4F4503DA"
    insecure: false

After adding the dependencies to your config file, install them using the Chromia CLI:

chr install

Specify entry file

Per default configuration, in your chromia.yml the entry file should be src/ but, to keep everything organized and ready for your project to grow, we suggest specifying it.

compile:
  rellVersion: 0.13.14
  source: rell/src

Next Steps

With your project set up and dependencies installed, you're ready to:

1. Create your first module
2. Create and mint tokens
3. Make your tokens interoperable
