# Register Names

### Registration params

```javascript
{
    chainId: 97,
    domainName: 'test001',
    duration: 1, // Unit (year)
    bulkRegistrarControllerAddress: '0xbd418F36bC5cAB3B3A81ecd9a6a461b454328d92',
    registrarAddress: '0xFe166d97c891A47c732c8b564A842e05dac10eD9'
}

import { Services, evm } from '@jazdid/jaz-did-sdk';
```

### Get the price of registering a domain name

```javascript
const renewPrice = await evm.bulkRegistrarController.getRenewPrice({
  bulkRegistrarControllerAddress,
  data: [
    {
      registrarAddress,
      domainNames: [{ name: domainName, duration: 1 }],
    },
  ],
}, {chainId});

// Response:
console.log('renewPrice, \n', JSON.stringify(renewPrice, null, 2));
{
  "0xFe166d97c891A47c732c8b564A842e05dac10eD9": {
    "test001": {
      "domainName": "test001",
      "durations": "31556952",
      "currency": "0x441950B67fc906756Dc0a1648bD07762182Db403", // Tokens used for payment
      "cost": "5000000000000000000"
    }
  }
}

```

### Generate registration order

<pre class="language-javascript"><code class="lang-javascript">const { registarOrdersPrice, registarOrders } = await evm.bulkRegistrarController.registerByOrders(
  renewPrice, {chainId, account}
);

// Response:

// Subsequent, used when signing the order
console.log('registarOrders, \n', JSON.stringify(registarOrders, null, 2));
<strong>[
</strong>  {
    "chainId": 97,
    "registrar": "0xFe166d97c891A47c732c8b564A842e05dac10eD9",
    "name": "test001",
    "walletAddress": "0x089279aC5a9305B3F530d8439ae16cb678F48e31",
    "duration": "31556952"
  }
]

// Fees for registering a domain name
console.log('registarOrdersPrice, \n', JSON.stringify(registarOrdersPrice, null, 2));
{
  "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE": "0",
  "0x441950B67fc906756Dc0a1648bD07762182Db403": "5000000000000000000"
}
</code></pre>

### Coroutine Task

```javascript
const coroutineTask = [
  // approve token
  evm.bulkRegistrarController.registerByApprove({ mixedRegistrarControllerAddress, registarOrdersPrice }),
  
  // Sign order
  evm.bulkRegistrarController.registerBySigner({
    registarOrders,
  }),
];

const [_1, registerSig, _2] = await Promise.all(coroutineTask);

// Execute wait time after signature
await evm.bulkRegistrarController.registerByWaitTime(mixedRegistrarControllerAddress, {chainId});

// Response

// Signed order data
console.log(JSON.stringify(registerSig, null, 2));

{
  "signed": [
    {
      "issuer": "0xa076C59bc18973861325BAec94A7BD010d94EC41",

    }
  ],
  "unsigned": []
}
```

### Registeration name

```javascript
const registerByPay = await Api.evm.bulkRegistrarController.registerByPay({
  mixedRegistrarControllerAddress,
  registarOrdersPrice,
  registerSig,
});

// This variable is used in the following (step 6) as a parameter 
// for judging the successful and failed registration of the domain name
const nameRegistered = registerByPay.events; 
```

### Registration result

```javascript
const registerByResult = await evm.bulkRegistrarController.registerByResult({
  registersByPay: nameRegistered,
  registarOrders,
});

// Response
console.log(JSON.stringify(registerByResult, null, 2));

{
  "success": [],
  "fail": []
}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.jazdid.com/developers/register-names.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
