# mint

## Description

The `estimateFee` function is an asynchronous function used to estimate the gas fee required for the `mint` operation of an ERC1155 token on a specific blockchain and environment. 

## Parameters

| Parameter           | Data Type | Description                                                                      |
| ------------------- | --------- | -------------------------------------------------------------------------------- |
| `blockchain`        | string    | The blockchain on which the ERC721 token exists.                                 |
| `contract`          | string    | The contract type, in this case, 'erc721'.                                       |
| `functionType`      | string    | The type of function for which to estimate the fee, in this case, 'mint'.        |
| `env`               | string    | The environment or network of the blockchain.                                    |
| `amount (optional)` | number    | The amount of ERC20 tokens to be minted. (Only required for 'mint' functionType) |

## Response

| Field          | Data Type | Description                                                           |
| -------------- | --------- | --------------------------------------------------------------------- |
| `code`         | number    | The response code indicating the success or failure of the operation. |
| `result`       | number    | The estimated fee for the contract deployment.                        |
| `VLRYEstimate` | number    | The estimated fee in VLRY (virtual asset).                            |
| `USDEstimate`  | number    | The estimated fee in USD (United States Dollar).                      |

## Example Request and Response

### Prerequisites

Before making requests with Volary SDK, you must have it installed.

You can install Volary SDK using either **`npm`** or **`yarn`**. Use the following commands to install Volary SDK:

<br>

```sh
npm install @nest25/evm-chains-lib
OR
yarn add @nest25/evm-chains-lib
```

### Request

Here is an example of how to make a `mint` request using the Volary SDK:

```sh
const { Nft } = require('@nest25/evm-chains-lib');

const nft = new Nft('testnet');

async function main() {
    const result = await nft.estimateFee('eth', 'erc1155', 'mint', 1);
    console.log("result", result);
}

main();
```

### Response

```sh
result {
        code: 1,
        result: 0.011711203649552238,
        VLRYEstimate: 147.52618853296894,
        USDEstimate: 22.12892827994534
      }
```

### Use Cases

* **Estimate ERC20 Mint Gas Fee:** By invoking this function with the appropriate blockchain, contract, functionType ('mint'), and environment, you can estimate the gas fee required for the `mint` operation of an ERC1155 token.
* **Supporting Multiple Blockchains:** The function allows estimating gas fees for ERC1155 mint operations on different blockchains by specifying the blockchain parameter (e.g., 'Ethereum', 'Binance Smart Chain', etc.).
* **Providing Results in Different Currencies:** The function returns the estimated gas fee in the native currency of the specified blockchain, as well as its equivalent in VLRY and USD, providing flexibility for users who prefer different currencies.
