# One Click

> One Click allows delegated trading through an authorized proxy wallet. Before calling `/send` endpoints, complete the authorization flow.

## Query Authorization Status

```
GET /api/v1/1ct/status
```

Response `data`:

| Field       | Type   | Description                                               |
| ----------- | ------ | --------------------------------------------------------- |
| `status`    | string | Authorization status. `/send` endpoints require `enable`. |
| `delegatee` | string | Proxy wallet address.                                     |

***

## Generate EIP-712 Payload

```
POST /api/v1/1ct/prepare
```

### Request Body

| Field      | Type   | Required | Description                                                |
| ---------- | ------ | -------- | ---------------------------------------------------------- |
| `deadline` | number | Yes      | EIP-712 signature deadline (Unix seconds). ≤ `4294967295`. |

### Response `data`

| Field         | Type   | Description                    |
| ------------- | ------ | ------------------------------ |
| `delegatee`   | string | Proxy wallet address.          |
| `signPayload` | object | EIP-712 typed data.            |
| `nonce`       | number | Delegate nonce.                |
| `deadline`    | number | Deadline matching the request. |

### signPayload Structure

```json
{
  "domain": {
    "name": "OneClickRouter",
    "version": "1",
    "chainId": 10143,
    "verifyingContract": "0x..."
  },
  "types": {
    "EIP712Domain": [
      { "name": "name", "type": "string" },
      { "name": "version", "type": "string" },
      { "name": "chainId", "type": "uint256" },
      { "name": "verifyingContract", "type": "address" }
    ],
    "Delegate": [
      { "name": "user", "type": "address" },
      { "name": "delegatee", "type": "address" },
      { "name": "nonce", "type": "uint64" },
      { "name": "deadline", "type": "uint32" }
    ]
  },
  "primaryType": "Delegate",
  "message": {
    "user": "0x...",
    "delegatee": "0x...",
    "nonce": 0,
    "deadline": 1893456000
  }
}
```

***

## Enable One Click

```
POST /api/v1/1ct/enable
```

### Request Body

| Field       | Type   | Required | Description                                               |
| ----------- | ------ | -------- | --------------------------------------------------------- |
| `signature` | string | Yes      | User's EIP-712 signature on `signPayload` (65 bytes hex). |
| `deadline`  | number | Yes      | Deadline matching the signature payload.                  |

{% hint style="warning" %}
`signature` is a `0x`-prefixed 65 bytes hex. `deadline` **must** use the same value returned by `/prepare`.
{% endhint %}

### Node.js Signature Example (ethers v6)

```js
import { Wallet } from "ethers";

const { signPayload, deadline } = prepareResponse.data;
const wallet = new Wallet(process.env.USER_PRIVATE_KEY);

// Verify signer address matches
if (wallet.address.toLowerCase() !== signPayload.message.user.toLowerCase()) {
  throw new Error("signer address must match signPayload.message.user");
}

// ethers v6 signature
const signature = await wallet.signTypedData(
  { ...signPayload.domain, chainId: BigInt(signPayload.domain.chainId) },
  { Delegate: signPayload.types.Delegate },
  {
    ...signPayload.message,
    nonce: BigInt(signPayload.message.nonce),
    deadline: BigInt(signPayload.message.deadline),
  }
);

console.log({ signature, deadline });
```

***

## Disable One Click

```
POST /api/v1/1ct/disable
```

No request body. Use empty string for `RAW_BODY` in signing.

***

## Available Send Endpoints

After One Click is enabled, use these `/send` endpoints for delegated trading:

| Operation    | Endpoint                        | Method |
| ------------ | ------------------------------- | ------ |
| Place Order  | `/api/v1/orders/send`           | POST   |
| Cancel Order | `/api/v1/orders/{orderId}/send` | DELETE |
| Deposit      | `/api/v1/cash/deposits/send`    | POST   |
| Withdraw     | `/api/v1/cash/withdrawals/send` | POST   |

Internal flow: build calldata first → send transaction via One Click. Order, deposit, and withdrawal endpoints auto-record txHash on success.
