# Run a Data Reporter (testnet)

## Prerequisites

* A working[ node](https://docs.tellor.io/tellor/running-palmito-testnet/node-quick-start-testnet).
* An account for creating a reporter that has either [created](https://docs.tellor.io/tellor/running-palmito-testnet/run-a-layer-validator) or [delegated](https://docs.tellor.io/tellor/command-line-usage/leveraging-layerd/delegate-to-a-validator) to a validator.

#### 1) Configure a Reporter on Tellor

Use the `layerd` cli register and initialize your reporter configuration. Commission-rate and min-tokens-required are shown at safe values, but can be adjusted (now or later) for personal preference:

{% code overflow="wrap" %}

```bash
# create-reporter [commission-rate] [min-tokens-required] [moniker] [flags]
./layerd tx reporter create-reporter 0.05 1000000 REPORTER_MONIKER --from YOUR_ACCOUNT_NAME --chain-id layertest-5 --fees 10loya --yes
```

{% endcode %}

Parameters:

* A (example) `commission-rate` of `0.05` means that you get 5% of rewards from your selectors.
* A (example) `min-tokens-required` value of `1000000` prevents spam by requiring that selectors have at least 1 TRB in their wallet. This can be changed later.
* Choose a `REPORTER_MONIKER` that you love! (It does not need to be the same as your validator moniker.)

#### 2) Check if your reporter was created successfully:

```sh
./layerd query reporter reporters | grep -A 7 YOUR_TELLOR_ADDRESS
```

If your reporter was created successfully, this will output your reporter information.

#### 3) Download the latest `reporterd` binary:

{% tabs %}
{% tab title="Linux" %}
{% code overflow="wrap" %}

```sh
mkdir -p ~/layer/binaries/reporter && cd ~/layer/binaries/reporter && wget https://github.com/tellor-io/layer-daemons/releases/download/v0.1.7/reporterd_Linux_x86_64.tar.gz && tar -xvzf reporterd_Linux_x86_64.tar.gz && rm reporterd_Linux_x86_64.tar.gz
```

{% endcode %}
{% endtab %}

{% tab title="Mac" %}
{% code overflow="wrap" %}

```sh
mkdir -p ~/layer/binaries/reporter && cd ~/layer/binaries/reporter && wget https://github.com/tellor-io/layer-daemons/releases/download/v0.1.7/reporterd_Darwin_arm64.tar.gz && tar -xvzf reporterd_Darwin_arm64.tar.gz && rm reporterd_Darwin_arm64.tar.gz
```

{% endcode %}
{% endtab %}
{% endtabs %}

#### 4) Create .env

Be sure to configure these variables here or in your shell. (The .env file is required even if it's empty):

{% code overflow="wrap" %}

```sh
ETH_RPC_URL="wss://a.good.sepolia.rpc.url"
ETH_RPC_URL_PRIMARY="wss://a.good.sepolia.rpc.url"
ETH_RPC_URL_FALLBACK="https://another.sepolia.rpc.url"
TOKEN_BRIDGE_CONTRACT="0x62733e63499a25E35844c91275d4c3bdb159D29d"
WITHDRAW_FREQUENCY=3600
REPORTERS_VALIDATOR_ADDRESS=tellorvaloper1egaks...
CMC_PRO_API_KEY=YOUR_COINMARKETCAP_API_KEY
SUBGRAPH_API_KEY=YOUR_GRAPH_API_KEY
INFURA_API_KEY=YOUR_INFURA_API_KEY
ALCHEMY_API_KEY=YOUR_ALCHEMY_API_KEY
```

{% endcode %}

*Note: The API keys are not required, but reporters should consider setting them to enable reporting for all tipped feeds. This ensures maximum earnings.*

#### 5) Start the reporter:

{% code overflow="wrap" %}

```bash
./reporterd --chain-id layertest-5 --grpc-addr 0.0.0.0:9090 --from ACCOUNT_NAME --home ~/.layer --keyring-backend test --node tcp://0.0.0.0:26657
```

{% endcode %}

Note: Optional flags may be used to establish a stream of profit taking for your operation:

{% hint style="info" %}
**Optional flags for auto-unbonding:**\
`--auto-unbonding-frequency` : The frequency (in days) with which you would like to withdraw rewards (unlocked after 21 days).

`--auto-unbonding-amount` : The amount of TRB (in loya) which you would like to auto-unbond.

`--auto-unbonding-max-stake-percentage` : A safeguard against automatically unbonding too much. Set this to a percentage of your stake ( 0.01 for 1%)
{% endhint %}

Here is an example start command for a reporter who wants to automatically unbond 2.999 TRB (2999999loya) per day with a maximum set to 1% of their total stake:

{% code overflow="wrap" %}

```bash
./reporterd --chain-id layertest-5 --grpc-addr 0.0.0.0:9090 --from ACCOUNT_NAME --home ~/.layer --keyring-backend test --node tcp://0.0.0.0:26657 --auto-unbonding-frequency 1 --auto-unbonding-amount 2999999 --auto-unbonding-max-stake-percentage 0.01
```

{% endcode %}

{% hint style="success" %}
You can set up a grafana dashboard using [this\_guide](https://docs.tellor.io/tellor/setting-up-a-grafana-dashboard-for-your-layer-node) to monitor things in Tellor such as average gas price for submitting a report, block times, total bonded tokens, etc.
{% endhint %}

Congratulations on becoming a Tellor Reporter! 🎉
