# Multichain setup

#### The guide below is for running a node on both NeuroWebAI and Gnosis chain.&#x20;

{% hint style="info" %}
OriginTrail DKG V6 nodes are chain agnostic. You can set up one node on a server and use the same node on different blockchains. Each chain requires 50k TRAC to activate the node on that chain and to start submitting commits (winning assets).&#x20;

\
Example:\
To run a node that submits commits on both NeuroWebAI and Gnosis, you will require:

* 50k TRAC on NeuroWebAI + 2 NEURO for gas
* 50k TRAC on Gnosis + GNO for gas

The delegated stake can come from you or someone else.
{% endhint %}

{% hint style="info" %}
The DKG V6 on Gnosis is expected to go live in mid February 2024 alongside delegated staking. Delegated staking on NeuroWebAI will come at a later time.&#x20;
{% endhint %}

## Step 1 - Preparations

Begin by obtaining xDAI for operations on Gnosis chain through their [**faucet**](https://www.gnosisfaucet.com/).&#x20;

If you require more xDAI, you can use [**Jumper**](https://jumper.exchange/) to swap any assets to xDAI on Gnosis.

Since Gnosis is EVM compatible, you can use your Ethereum wallet on MetaMask or Ledger for all operations on the chain.&#x20;

If you want to delegate to your own node, bridge your ERC-20 TRAC from Ethereum to Gnosis by using the [**Omnibridge**](https://omnibridge.gnosischain.com/bridge)**.**

{% hint style="info" %}
A node can be fully operational with delegated stake only as long as the total stake amount is 50k TRAC or above.
{% endhint %}

Now, you need an [**Archival RPC Endpoint** ](https://docs.gnosischain.com/tools/rpc/)to communicate with the Gnosis chain. Note that not all providers provide archival endpoints. You will need to sign up through their links and get an Archival RPC Endpoint.&#x20;

{% hint style="success" %}
For a free Archival RPC Endpoint, try out [**BlockPi**](https://dashboard.blockpi.io/) or [**OnFinality**](https://app.onfinality.io/).
{% endhint %}

## Step 2 - Configurations

Head to your node config with the alias

```
otnode-config
```

or manually

```
nano ~/ot-node/.origintrail_noderc
```

Then, add the following to your config file

```
"gnosis:100": {
  "enabled": true,
  "config": {
    "rpcEndpoints": [
      "https://<desired_rpc_endpoint>"
      ],
    "gasPriceOracleLink": "https://gnosis.blockscout.com/api/v1/gas-price-oracle",
    "sharesTokenSymbol": "shares_token_symbol",
    "sharesTokenName": "shares_token_name",
    "operatorFee": "5",
    "operationalWallets": [
      {
        "evmAddress": "0x0bf...",
        "privateKey": "0x1e3..."
      }
    ],
    "evmManagementWalletPublicKey": "0xd09..."
   }
}
```

The end result should look like this. Double check for syntax errors!

```

  "modules": {
    "blockchain": {

                "privateKey": "0x1e3..."
              }
            ],
            "evmManagementWalletPublicKey": "0xd09..."
          }
        }
      }
    },

          "enabled": true,

          "config": {
            "repositories": {
              "privateCurrent": {

                "name": "private-current",
                "username": "admin",
                "password": ""
              },
              "privateHistory": {

              },
              "publicCurrent": {
                "url": "http://localhost:9999",
                "name": "public-current",
                "username": "admin",
                "password": ""
              },
              "publicHistory": {
                "url": "http://localhost:9999",
                "name": "public-history",

                "password": ""
              }
            }
          }
        }
      }
    }
  }
}
```

{% hint style="danger" %}
Before applying the config changes by restarting the node, make sure you added your operator fee. Once the config is applied, you will not be able to change operator fee for 28 days.&#x20;
{% endhint %}

ctrl+x and ctrl+s to save and restart your node

```
otnode-restart && otnode-logs
```

{% hint style="success" %}
If you added everything successfully, your node will show:

**blockchain module initialized with implementation: gnosis:100**
{% endhint %}

## Step 3 - Set node ask

The default ask is set to 0.01 in the script below. Please change it to your desired ask price.&#x20;

```
npm -C /root/ot-node/current run set-ask -- --rpcEndpoint=https://astrosat-parachain-rpc.origin-trail.network/ --ask=0.01 --privateKey=$(jq -r '.modules.blockchain.implementation.otp.config.evmOperationalWalletPrivateKey' /root/ot-node/.origintrail_noderc) --hubContractAddress=0x5fA7916c48Fe6D5F1738d12Ad234b78c90B4cAdA
```

## Step 4 - Add stake

Visit [**Houston**](https://houston.origintrail.io/login) **and connect your admin wallet. Head to Service Tokenomics and follow the on screen instructions to set up node operator fee, node ask and node stake!**

**You can then visit the**[ **staking dashboard**](https://dkg.origintrail.io/staking) to find your node.

Done!
