# Operator Onboarding

This page describes how to create an operator, register it in SatLayer, and create a vault on SatLayer testnet. SatLayer's testnet exists as a set of smart contracts on top of Babylon's own [testnet](https://testnet.babylon.explorers.guru/) `bbn-test-5`. \
\
In order to onboard onto SatLayer testnet, operators have to complete the following steps:\
\
1\) Generate an address via a wallet app such as Keplr.

2\) Instantiate your address as a signer. 

<pre class="language-typescript"><code class="lang-typescript"><strong>const chainId = "bbn-test-5";
</strong>const endpoint = "https://babylon-testnet-rpc.nodes.guru";

import { GasPrice } from "@cosmjs/stargate";
import { SigningCosmWasmClient } from "@cosmjs/cosmwasm-stargate";
import { DirectSecp256k1HdWallet } from "@cosmjs/proto-signing";
import { stringToPath } from "@cosmjs/crypto";

const gasPrice = GasPrice.fromString("0.002000ubbn");

// create signer object using mnemonic phrase you created in Keplr
const signer = await DirectSecp256k1HdWallet.fromMnemonic("[YOUR MNEMONIC PHRASE]", {
  prefix: "bbn",
});

const client = await SigningCosmWasmClient.connectWithSigner(endpoint, signer, { gasPrice });
</code></pre>

3\) Register your operator in the `bvs-registry`.&#x20;

<pre class="language-typescript"><code class="lang-typescript"><strong>const registry = "bbn1a9tleevqygn862ll2la49g637fjttfzzlttdrmmua35fadpuvnksuyud7a";
</strong><strong>
</strong>const executeMsg = {
    register_as_operator: {
        metadata: {
            name: "[YOUR OPERATOR NAME]",
            uri: "[YOUR OPERATOR URI]"
        }
    }
};

await client.execute("[YOUR OPERATOR ADDRESS]", registry, executeMsg, "auto");
</code></pre>

4\) Create a `Vault` to start accepting collateral. `Vaults`can be configured to accept either `cw20`or `bank`module tokens.

**CW20:**

```typescript
const factory = "bbn1tnpg0hs099tpmaavzjzx02kvf7lcqhwmkrp0spg30aejmfydxnkqfzwdyx";

const executeMsg = {
    deploy_cw20: {
        cw20: "[YOUR CW20 ADDRESS]"
    }
};

const response = await client.execute("[YOUR OPERATOR ADDRESS]", factory, executeMsg, "auto");
```

Where the `cw20`argument is the address of the cw20 token that you wish to accept as collateral.

**Bank Module:**

<pre class="language-typescript"><code class="lang-typescript">const factory = "bbn1tnpg0hs099tpmaavzjzx02kvf7lcqhwmkrp0spg30aejmfydxnkqfzwdyx";

const executeMsg = {
    deploy_bank: {
        denom: "[YOUR BANK DENOM]"
    }
};

<strong>const response = await client.execute("[YOUR OPERATOR ADDRESS]", factory, executeMsg, "auto");
</strong></code></pre>

Where the `denom`argument is the `denom`of the `x/bank`module token which you wish to accept as collateral.&#x20;

5\) Whitelist your vault in the `router`&#x20;

<pre class="language-typescript"><code class="lang-typescript">const router = "bbn1tztx8vkgw24rm5f6ny52qyt6kpg7gyfd5nggvfgjjfj8n7ggkx7qfhvdum";

const executeMsg = {
<strong>  set_vault: {
</strong>    vault: "[YOUR VAULT ADDRESS]",
    whitelisted: true,
  }    
};

await client.execute("[YOUR OPERATOR ADDRESS]", router, executeMsg, "auto");
</code></pre>

After completing these steps, you will have created an `operator`and a `vault`, linked them together, and whitelisted this `vault`in the router. The final step to get set up on testnet is to identify a Bitcoin Validated Service (BVS) you wish to validate and register to validate it.

6\) Register services you want to validate to your `operator`. First you need to identify the address of the service in SatLayer. This address represents the BVS'es on-chain footprint.&#x20;

<pre class="language-typescript"><code class="lang-typescript"><strong>const executeMsg = {
</strong>    register_service_to_operator: {
        service: "[SERVICE ADDRESS]"
    }
}

await client.execute("[YOUR OPERATOR ADDRESS]", registry, executeMsg, "auto");
</code></pre>
