## YourService Signer

[YourService](https://yourservice.com) provides [brief description of your
service].

### Prerequisites

- YourService account
- API credentials
- Funded wallet

### Setup

1. Get your API credentials from [dashboard link]
2. Create a wallet...
3. Configure environment variables:

\```bash YOUR_SERVICE_API_KEY="your_api_key"
YOUR_SERVICE_API_SECRET="your_api_secret"
YOUR_SERVICE_WALLET_ID="your_wallet_id" \```

### Configure signers.toml

\```toml [signer_pool] strategy = "round_robin"

[[signers]] name = "yourservice_main" type = "your_service" api_key_env =
"YOUR_SERVICE_API_KEY" api_secret_env = "YOUR_SERVICE_API_SECRET" wallet_id_env
= "YOUR_SERVICE_WALLET_ID" weight = 1 \```

### Run Kora with YourService Signer

\```bash kora rpc start --signers-config signers.toml \```

feat(signer): add YourService signer configuration support

- Add YourServiceSignerConfig struct
- Add YourService variant to SignerTypeConfig enum
- Add build and validation logic for YourService
- Add example configuration files
- Add documentation to SIGNERS.md
- Add integration tests
