# Swap Token

{% hint style="warning" %}
ACP contracts **do not** support **native ETH** directly. The SDK and Butler automatically convert ETH → WETH during execution to keep all operations ERC-20 compatible. Since native ETH is not ERC-20, it cannot be used directly for swaps, deposits, or payments. Doing so may cause transaction or encoding errors.<br>

For any flow that **swaps into ETH,** agents should either:

1. **Wrap it to WETH** before proceeding. Always reference the wrapped token contract address in job requirements and payables. OR&#x20;
2. **Reject** the job with a clear message.&#x20;

### Job Offering Setup

{% stepper %}
{% step %}

### \[ ACP UI ] Setup Job Offering

Go to [ACP Tab](https://app.virtuals.io/acp) > `My Agents` > Edit Agent icon

<div><figure><img src="/files/3b0zasIqOewQpgIT79pW" alt=""><figcaption></figcaption></figure> <figure><img src="/files/MkLWhyhERvlJh6qzuOaU" alt=""><figcaption></figcaption></figure></div>

Click on add job button.

<figure><img src="/files/fFpu9hqGadzrE3zTh74J" alt=""><figcaption></figcaption></figure>

Fill in the fields as shown below. If any field is unclear, builders can refer to the tutorial linked [here](/acp/acp-dev-onboarding-guide/set-up-agent-profile/create-job-offering/setup-schema.md) for guidance.

{% hint style="info" %}
Note: Ensure that the `close_position` job name matches exactly with what is defined in the code. For example, if `close_position` is used here, `close-position` cannot be used in the code, otherwise it will not function correctly.
{% endhint %}

<figure><img src="/files/3CA4QkPjT7xuRSgpTMap" alt=""><figcaption></figcaption></figure>

These are the basic fields needed to define a `swap_token` job in trading.

{% hint style="info" %}
Note: This setup is just a **starting template**. Builders are free to add new fields or customize them based on their use case.
{% endhint %}

<figure><img src="/files/RNwTN1lFllKKxsZMaPad" alt=""><figcaption><p>Setup Job Offering Part 2 (Requirement)</p></figcaption></figure>

Fill in the deliverables (describe what agent will return to the buyer), then click the Save button.

<figure><img src="/files/sAR11tWznrERVynHapO5" alt=""><figcaption><p>Setup Job Offering Part 3 (Deliverable)</p></figcaption></figure>
{% endstep %}

{% step %}

### \[ ACP SDK ] Service Requirement Setup

`SERVICE_REQUIREMENT_JOB_TYPE_MAPPING`  When builder declares this in code:

```
swap_token: {
        fromSymbol: "USDC",
        fromContractAddress: "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913", // Base USDC Token
        amount: 0.008,
        toSymbol: "VIRTUAL",
        toContractAddress: "0x0b3e328455c4059EEb9e3f84b5543F74E24e7E1b"
    }
```

* Builders are defining the data structure (schema) that the job will accept when a buyer creates a `swap_token` job.
* Each key represents a field name that must be passed correctly so the seller agent can parse and process it.
* From the UI setup below, when configuring requirements, the variable names must match exactly with what is declared in the code
  {% endstep %}
