# Run DKG

Repository: [Distributed Key Generation GitHub](https://github.com/radiusxyz/distributed_key_generation)

1. Clone the repository

   ```sh
   git clone https://github.com/radiusxyz/distributed_key_generation
   ```
2. Build the binary

   ```jsx
   cd distributed_key_generation
   cargo build --release
   ```
3. Set up environment variables in `./scripts/execute/env.sh`.
4. Initialize the system:

   ```bash
   ./scripts/execute/01_init_key_generator.sh
   ```
5. Start the system:

   ```bash
   ./scripts/execute/02_run_key_generator.sh
   ```
6. Set up environment variables in `./scripts/rpc-call/env.sh`.
7. Initialize RPC: This action serves for registering a key generator by submitting its address and RPC endpoints to an internal system.

   ```bash
   ./scripts/rpc-call/10_initialize.sh
   ```
